Using MvxGridView in MvvmCross - c#

What I want to do is s simple screen showing multiple items in a Grid. This can on android easily be archived using a GridView.
In MvvmCross I guess I have to use MvxGridView to archive the same.
Here is my axml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Mvx.MvxGridView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
local:MvxBind="ItemsSource Items"
local:MvxItemTemplate="#layout/itemview" />
</LinearLayout>
The itemview:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<TextView
android:text="Text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/textView1"
local:MvxBind="Text Name" />
</LinearLayout>
My ViewModel:
using System.Collections.ObjectModel;
using Cirrious.MvvmCross.ViewModels;
namespace GridViewBug.Core.ViewModels
{
public class FirstViewModel
: MvxViewModel
{
public FirstViewModel()
{
Items = new ObservableCollection<TestClass>();
Items.Add(new TestClass { Name = "Test1" });
Items.Add(new TestClass { Name = "Test2" });
}
private string _hello = "Hello MvvmCross";
public string Hello
{
get { return _hello; }
set { _hello = value; RaisePropertyChanged(() => Hello); }
}
public ObservableCollection<TestClass> Items { get; set; }
}
public class TestClass
{
public string Name { get; set; }
}
}
And here what happens when I run this example:

What I'm doing wrong?
I'm using the latest stuff I can get from Nuget. Running on Mono Android 4.6.4 in VS2012
Here is the repo with the complete code:
https://github.com/sschoeb/MvvmCrossGridViewProblem


From the tracem it looks like a straight-forward bug, probably a regression that occured somewhere while fixing another issue.
Your best bet would be to open an issue for this on GitHub - https://github.com/slodge/MvvmCross/issues/new? Or you could fork the source and fix it in your branch.
In the meantime, maybe try using the MvxListView? Or create a new bindable ViewGroup?

I have a physical device connected. When the phone is locked and I deploy the application after unlocking, the application works and everything is fine. But if the screen is unlocked and I deploy I get the following error. In this case, everything is ok on the emulator. Help me understand this nonsense.

"The property {property} does not exist on type {type}" - but it does. OData configuration issue?

I have a Blazor WASM application that has an OData back-end. I'm trying to configure the NavigationProperty of one of my models so that I can use the $expand= query parameter to return more data but I keep getting the following error when trying to make a PATCH request (GET works just fine):
Microsoft.OData.ODataException: The property 'JobId' does not exist on type 'Coin.ODataOrderHeader'. Make sure to only use property names that are defined by the type or mark the type as open type.
But it does exist! Not just in the model:
public partial class ODataOrderHeader
{
[Key]
public int OrderId { get; set; }
[Column("JobID")]
[ForeignKey("Job")]
public int JobId { get; set; }
...
[System.Text.Json.Serialization.JsonPropertyName("Job")]
public virtual Jobs Job { get; set; }
}
But in the $metadata document as well:
<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx">
<edmx:DataServices>
<Schema Namespace="Coin" xmlns="http://docs.oasis-open.org/odata/ns/edm">
...
<EntityType Name="ODataOrderHeader">
<Key>
<PropertyRef Name="OrderId" />
</Key>
<Property Name="OrderId" Type="Edm.Int32" Nullable="false" />
<Property Name="JobId" Type="Edm.Int32" />
...
<NavigationProperty Name="Job" Type="Coin.Jobs">
<ReferentialConstraint Property="JobId" ReferencedProperty="JobId" />
</NavigationProperty>
</EntityType>
...
</Schema>
</edmx:DataServices>
</edmx:Edmx>
Here is the code that creates the model:
private IEdmModel GetEdmModel()
{
var builder = new ODataConventionModelBuilder();
builder.Namespace = "Coin";
builder.ContainerName = "CoinContainer";
...
var orders = builder.EntitySet<ODataOrderHeader>("Orders");
return builder.GetEdmModel();
}
I should probably point out, ODataOrderHeader is more of a DTO type whereas Jobs is an EF scaffolded type.
Here is the Simple.OData.Client code that calls the API:
private async void UpdateItem()
{
ODataClient client = new ODataClient(new ODataClientSettings(HttpClient, new Uri("odata", UriKind.Relative)));
await client.For<ODataOrderHeader>("Orders")
.Key(currentOrder.OrderId)
.Set(currentOrder)
.UpdateEntryAsync();
}
And here's the controller action that the above code is calling:
[ODataRoute("/orders({key})")]
public async Task<IActionResult> Patch([FromODataUri] int key, Delta<ODataOrderHeader> order)
{
if (!ModelState.IsValid)
return BadRequest();
...
}
And lastly, the error message in its entirety:
Unhandled Exception:
Microsoft.OData.ODataException: The property 'JobId' does not exist on type 'Coin.ODataOrderHeader'. Make sure to only use property names that are defined by the type or mark the type as open type.

Uncaught ExitStatusThe program '' has exited with code -1 (0xffffffff).
Is there a configuration error I'm missing or is there something wrong with the controller action?

For anyone that stumbles across this in the future, I was able to uncover a little more information.
Firstly, by adding some data annotations [IgnoreDataMember] on my Jobs class and by adding {IgnoreUnmappedProperties = true} when instantiating the ODataClient, I was able to get a different error. Something along the lines of: The key 'JobId' does not exist in the dictionary.
For context, I'm trying to do what OData refers to as a "deep update". I want to update a child entity while updating the parent entity. However, Simple.OData.Client does not support deep updates or deep linking or deep creation. Here's a 5 year old question from Simple.OData.Client's GitHub page that talks about this and unfortunately, it would appear that development of this package has ceased ("Future of Simple.OData.Client" and "Project Dead?"). Since it doesn't support "deep updates", it doesn't know how to generate the request URL which is why my PATCH request was failing.

realm.xamarin thows error "Data type mismatch" even when same data type

i am using realm.xamarin 0.75 with xamarin forms and while executing query, i get a weird error. the query is
DateTimeOffset fromOffset = new DateTimeOffset(fromDate);
DateTimeOffset toOffset = new DateTimeOffset(toDate);
var config = DependencyService.Get<IDatabase>().GetConfiguration();
using (var realm = Realm.GetInstance(config))
{
return realm.All<Measurements>()Where(o => o.CreatedDateTime >= fromOffset && o.CreatedDateTime <= toOffset).OrderByDescending(o => o.CreatedDateTime).ToList();
}
And the error is:

i suscpect DateTimeOffset could be causing the issue.
i checked the source code at https://github.com/realm/realm-dotnet
but couldn't find anything.

I found the issue. It happens when the class for RealmObject(in my case Measurements) is not inheriting directly from RealmObject.
My class Measurements was inheriting from a class BaseModel (i created this class for internal purpose) and this BaseModel class was inheriting from RealmObject.
When i removed this and made Measurements inherit directly from RealmObject, i doesn't throws exception.
From Dimitris Tavlikos 's comment,
Realm Xamarin does not allow models to be further subclassed in any way. The CreateObject generic method only works if you use it for a class which descends directly from RealmObject.

The app has Write external storage permission.
Realm and Fody nuget packages installed properly, Fody weavers are present as expected..
It also crashes with same exception using HTC One X with Android 4.2

The above attempt had other issues. There is a real bug currently in Realm with storage on external storage - see the issue https://github.com/realm/realm-dotnet/issues/554 which is proving awkward to debug.

DotCMIS/Alfresco: "error in XML document" when calling GetRootFolder

With DotCMIS I can successfully start a session to an Alfresco 4.0.1 CMIS server.
But when I call session.GetRootFolder(), I get the exception below:
Unhandled Exception: DotCMIS.Exceptions.CmisConnectionException: Parsing exception! ---> System.InvalidOperationException: There is an error in XML document. ---> System.InvalidOperationException: Read by order only possible for encoded/bare format

An important part seems to be: Read by order only possible for encoded/bare format
My code is pretty much straight from the tutorial:
using System;
using System.Collections.Generic;
using DotCMIS;
using DotCMIS.Client.Impl;
using DotCMIS.Client;
using DotCMIS.Data.Impl;
using DotCMIS.Data.Extensions;
namespace tests.sln
{
class MainClass
{
public static void Main (string[] args)
{
// Connect to repository
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters[SessionParameter.BindingType] = BindingType.AtomPub;
parameters[SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/cmisatom";
parameters[SessionParameter.User] = "admin";
parameters[SessionParameter.Password] = "admin";
SessionFactory factory = SessionFactory.NewInstance();
ISession session = factory.GetRepositories(parameters)[0].CreateSession();
Console.WriteLine("Created CMIS session: " + session.ToString());
// Get the root folder
IFolder rootFolder = session.GetRootFolder(); // Error happens here
}
}
}
What did I miss?
In debug mode I can see DotCMIS.Client.Impl.Session.GetObject (objectId="workspace://SpacesStore/77acb21f-811c-49a3-be4d-5cc7f177f461" in the stack, not sure what it means but 77acb21f-811c-49a3-be4d-5cc7f177f461 is indeed the node reference of Alfresco's company_home.
If I change the URL to http://localhost:8080/alfresco/service/cmisatom in the code above, then a Not Found error appears earlier, at the GetRepositories line. So I am pretty sure my URL is correct.
I downloaded the DotCMIS source code and am debugging it in Monodevelop now.
With Wireshark I have identified the packet on which the exception happens:

It is valid XML.

It is a Mono bug. Mono crashes on <xsd:choice>.
See https://bugzilla.xamarin.com/show_bug.cgi?id=2907
Sub-answer:
You are using the old Alfresco CMIS URL.
Check:
http://localhost:8080/alfresco/service/cmis/index.html
