Since I upgraded to the latest version of SF, none of my combo boxes will populate.  This happens for all ComboBoxEdits that are set to populate by BO.  They were working before and now everytime a form with a combobox on it tries to load I get an error and the rest of the form quits loading.  I get an error with a stack trace like the following.  I also attached the SQL log from this morning.

I'm not sure why you're getting this error because I just tested it and it worked fine on this end... what you might do is put a break point in the method that you're using to populate the business object (FillWhatever()).  And step through the method until the current line lands on the End Sub.  Then, check Me.CurrentDataTable within the Watch window and make sure that the CurrencyType column does actually exist on the table...

Yep, did exactly what you said and it DOES have a CurrencyType field in there.  I have attached the screenshot so you can see what I mean.  This is happening on every combo box and I can't get to a lot of my forms to work.  Any other ideas?

What version of DevExpress are you using?

DevExpress version is 6.2.3

First of all, we beleive you otherwise you would not be posting out here.  But neither of us have been able to reproduce this.  Could you create a small sample project, you could use the StrataFrameSample database if you would like, so that we might be able to see this in action.  Obviously there is something different between what you are doing and what we are doing or there is another element in the forumula.

Also, you are the first to report this as well, so I do not think it is a framework wide thing.  Otherwise, we would have already heard about this since the 1.5.1 release has been out for 3 weeks now.

So if you could help us work through your problem, that would be great.  We want to help, but we need more information.

Ok, no problem.  I'll try to get together a sample project.  I figured this would be an interesting one to figure out.  I've looked through StrataFrame source code, my source code, and just haven't seen anything I could pinpoint as the cause.  Maybe a smaller project will shed some light on this.  Stay tuned

Great...thanks.

I now get a different error after I set up a sample project.  I used the customers table and just put a customers BO in the project from the StrataFrameSample db.  I then set the PopulationDataSourceSettings on the ComboBoxEdit to use a FillAll method which I added to the BO.  When I load the form, I get an error which says: "Exception has been thrown by the target of an invocation."  Please check out the project I am attaching and tell me if I've done something wrong here.  I have also attached a screenshot of the error I get in case it does something different on your end.  Thanks in advance.

Ok, I feel stupid now. My database wasn't pointing to the right place so that's why the invocation error.  I fixed it and it seems to populate from the Customers BO.  Let me try a couple of other things and see what I can come up with.
