Exception after closing File History dialog (from Commit Dialog) which was not completely loaded

[feinstaub]

Reproduce:

1. Change some files
2. Open Commit Dialog
3. Right click on a changed file and click "View file history"
4. Close the File History dialog before the Loading is finished
5. Exception occurs.

Exceptions ocurrs in many places.

Example 1:
syncContext.Post(state1 => UpdateColumnWidth(), null);
Example 2:
syncContext.Post(_ =>
{
FileChanges.FixedFilter = filter;
FileChanges.AllowGraphWithFilter = true;
FileChanges.Load();
}, null);

It is queued and invoked in main thread after control was disposed.
All fragments like aboves have to be rewriten to ensure that they are not operating on diposed data.

Thanks for the explanation. With the current dev version I cannot reproduce the issue anymore. I'll wait for the next release and check again.

I close this bug. Please comment if you can reproduce it.

I can reproduce, the slower computer you have the more exceptions occur.

After closed GE commit info tries to load.

        if (Settings.CommitInfoShowContainedInTags)
            ThreadPool.QueueUserWorkItem(_ => loadTagInfo(_revision));
