iam using MVVMCross 4.1.6 (tried on 4.1.4 aswell) and having an issue with a property of an item in a observable collection. It occurs when i repeatedly switch between my 2 tabs each with a MvxRecyclerView and a list of items which are connected together. Basically one is the normal list and one is a favoritelist.
Both of those lists get prepared by the data in the background when the fragment shows up by this method to unsure that all new data gets displayed:
private void updateChannels()
{
foreach (var category in CalCategories)
{
if (string.IsNullOrEmpty(m_searchString))
{
var channels = category.Channels.Where(o => o.Task == null).ToList();
if (category.Count != channels.Count)
{
category.Count = channels.Count;
}
if (channels.Count > 0)
{
if (!CalChannelList.Contains(category))
{
CalChannelList.Add(category);
}
if (category.Expanded)
{
foreach (var channel in channels)
{
if (!CalChannelList.Contains(channel))
{
CalChannelList.Add(channel);
}
}
}
}
}
else
{
var channels = category.Channels.Where(o => o.Name.Contains(SearchString) && o.Task == null).ToList();
if (category.Count != channels.Count)
{
category.Count = channels.Count;
}
if (channels.Count > 0)
{
if (!CalChannelList.Contains(category))
{
CalChannelList.Add(category);
}
if (category.Expanded)
{
foreach (var channel in channels)
{
if (!CalChannelList.Contains(channel))
{
CalChannelList.Add(channel);
}
}
}
}
}
}
}
The error occurs there after a certain amount of time just switching forth and back between the tabs and always happens at the line when the category.Count gets set.

06-02 12:24:13.942 E/mono-rt ( 6344):
Update
Seems to be related to the bindings and updating the ui elements. Maybe somehow the references for the elements get cleared up or not fully freed when an item gets removed? Atleast without the MvxBindings which gets changed during this process it doesnt crash.
Update 2
public abstract class BaseCategory : MvxNotifyPropertyChanged, IChannelItem
{
public bool Expanded { get; set; }
public int FavoriteCount
{
get { return m_iFavoriteCount; }
set { SetProperty(ref m_iFavoriteCount, value); }
}
public int Count
{
get
{
return m_iCount;
}
set
{
SetProperty(ref m_iCount, value);
}
}
public string Name { get; set; }
protected BaseCategory(string sName)
{
Expanded = false;
Count = 0;
FavoriteCount = 0;
Name = sName;
}
private int m_iCount;
private int m_iFavoriteCount;
public ChannelItemTypes CItemType { get { return ChannelItemTypes.Category; } }
}
And the layout which gets selected my a multititemtemplateselector:
<?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="wrap_content">
<android.support.v7.widget.CardView
android:foreground="?attr/selectableItemBackground"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
cardview:cardUseCompatPadding="true"
cardview:cardCornerRadius="2dp"
cardview:cardElevation="2dp"
cardview:contentPadding="10dp">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:layout_gravity="center_horizontal"
android:layout_marginRight="5dp"
android:padding="10dp"
android:textColor="@color/white"
android:textStyle="bold"
local:MvxBind="Text (Name+' '+Count)" />
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
Update 3 Apparently the updateChannels() method creates more and more data objects. Iam just not sure what might be the cause of it? The Binding to the UI-Element, the LinQ Command? Or am i just blind?
Update 4 I created now a seperate project with just a MvxRecyclerView and a ObservableCollection in a Fragment. If i click the button i add X new objects to the list after clearing the list. By watching it with the DeviceMonitor the objects just keeps increasing, so either i do something horribly wrong or something is wrong with the components i use.
https://github.com/Noires/MvxRecyclerViewLeakTest
Update 5 Though it was an issue, it was not related to the original problem. So at the moment i just changed the MVVMCross myself to prevent it and will check the real issue afterwards.
Update 6 Issue opened on https://github.com/MvvmCross/MvvmCross/issues/1379
