Thanks for letting us know, Larry!

For anyone else that may have experienced this problem, Infragistics was finally able to reproduce it. Installing NetAdvantage HotFix 6.3.20063.1059 fixes it.

I just received another reply from Infragistics tech support saying that they cannot reproduce the error. Since I haven’t seen any postings here of a similar error, maybe it’s something in my environment.  I tried uninstalling vol3, downloaded a new copy, re-installed and still received the same error. However since you were able to reproduce it using their standard distribution but not against their compiled source code I’m assuming that it’s something in the distribution or installation.  Since 2007 vol 1 seems to be functioning normally I’m going to forget about 2006 vol3 and move on.

Yes, I noticed the email that came in announcing 2007 vol 1... if the problem doesn't manifest itself in that version, then you might not get them to fix it in vol 3...

And, no, I don't think we have priority support, sorry, we have to wait in the same bucket as you do.

I guess I spoke too soon. I was able to reproduce the problem using one of their sample applications but they say they can’t reproduce it on their end and sent me back a sample application to try.  The sample they sent populated the UltraComboEditor directly and I was able to run it with no errors. It appears that the control must be bound to cause the error. I created an updated sample and sent it back to them and I’m still waiting for a response. They are no where close to providing the level of service that you guys do The sample is simple, just an UltraComboEditor on a standard Windows form with the following code in the form’s load event.

 

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim letters = New String() {"B", "A", "C", "E", "D"}

        Me.UltraComboEditor1.SetDataBinding(letters, "")

End Sub

 

Using that sample produces a null exception if SortStyle is set to anything other than “None” when run against 2006 Vol 3, Vol 2 runs okay.  If you guys have priority support with them you might try to see if you can get them to look at it. Since 2007 Vol 1 just came out I recompiled the SF wrapper for that version and so far everything looks okay.

Whew, I'm glad you were able to reproduce it with them... I thought I was going batty when it didn't fail after I rebuilt the source code...

Ben,

Thanks for looking into this. I did some more checking and found that I could reproduce the problem using the DataBinding VB sample that is distributed with the Net Advantage Suite… looks like it is definitely their problem. I’ve submitted a support request with them.

Yes, and no, Larry... when I drop a wrapped UltraComboEditor on a form and set the sort, then yes, it throws the exception... however the stack trace does not reference a single StrataFrame method.  So, I wanted to debug the issue and see what was being set to null, so I opened up the Infragistics source code, but since they do not distribute the .snk file for their source code, I had to change the reference to my compiled DLL.  When I did that, everything worked perfectly... no issues.  The only thing I did was change the reference.  It was the exact same code (at least I think it was... the source code they distribute might be different from the source code used to build their deployment DLLs).  So, I don't know what to tell you.  Yes, I can reproduce it, but looking at their code I cannot even fathom what might be throwing a NullReferenceException (all it does is retrieve a bunch of appearance stuff).  And when I build their source so that I can step through it, everything works fine, no NullReferences.

I was wondering if you were able to reproduce this issue. While I can develop in v1.6 it’s preventing me from actually using 1.6 in production.

Excellent... thanks for the details.
