Runtime Exception on Listbox Datasource

July 25, 2019, 04:13:26 PM

Hi

When im in page Design and choose the datasource for the Listbox component, i get the below exception and cant choose the table.
It doesnt happen always, possible cause could be that this specific field im choosing is part of a inner join (which in the listpage works fine)
But im no expert.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Update:
My theory above is confirmed, if the fieldname chosen is a field from a join the datasource picker crashes.
Possibly not a bug as the local field of the main table probably needs to be chosen in most cases (then it works)
However the Fieldlist for Fieldname then shouldnt show external table fields to choose.
