Hi

I’m not sure if this has been brought to your attention, and I do apologise if this is a duplicate query.

I have been testing our system after upgrading to 17.3, but I picked up an issue.
I managed to recreate the error I get on a sample project. (Attached)
I have noticed that this only occurs on the Web project, the Win project works. We currently use the Web Project for our system.

In the sample project I have 3 object. TblDebtor, TblJournalBatch and TblJournal.
I have set up these objects in the same way in which we use them.
If you navigate to Default > Tbl Journal Batch and click on New, then again click on New under Journal Lines and then look for a debtor.
Once you select the debtor the following error occurs:

Application Error

Hi George,

This is a known issue and our developers have fixed it. The fix will be included into the next maintenance update. In case of urgency, feel free to download a hotfix in this ticket: ASPxGridListEditor - FormatException is thrown when selecting an object in a lookup ListView shown from an aggregated collection.

P.S.
When you experienced an exception in DevExpress code, I recommend you locate its callstack and search for one or several topmost method names in our support database, because this behavior might be reported by someone else: https://search.devexpress.com/?q=ASPxGridViewContextMenu.SelectObject&m=SupportCenter
In addition, I recommend checking the Known Issues sections in our What's New documentation:
    all XAF issues that were created in v2016 vol 2.6.
    all XAF issues that were created in v2017 vol 1.3
