When trying to define an actor filter using custom information I get the following error:

I’m using Bonita 7.2 Community Edition.

Hi,

Maybe it’s a bug, when do you get this error exactly? When you try to create a new actor filter or when you’re using it in your process?

If it’s a bug, please post it in the bug tracker: https://bonita.atlassian.net/secure/Dashboard.jspa

Thanks

The error arises when I try create the filter. Actually, I’m unable to create it because the definition window turns irresponsive in the second next button.
