Hi guys,
I went through the same error, I was not able to find or had the time to understand the root cause of it, I imagine that should be related to updated references or some garbage inside the IIs VIDIR, nevertheless, what I did to sort it out was:
- Clone the eSpace where we had the dropdown search that was causing the error
- Rename the original eSpace to "<module name>_Old"
- Rename the cloned version to the original name,
and voilá it worked, in the cloned eSpace we no longer had the issue.
Note: In our case, the eSpace was an End User module that was not producing for any other module, in the case of being a _CW module or another kind of module that is producing for other modules, you need to update the producers for the new module.
