Expanding Collapsible Layout never finishes loading



The collapsed embedded layout never finishes expanding and can't be edited.

Error Messages

Not Applicable.

Steps to Reproduce

1.Create a section with collapsible layout.
2. When the section is opened at runtime, it displays "loading" and editing of the section is not possible.

Root Cause

A defect in Pegasystems’ code or rules. When a section is saved, a Java file is created. (In the section, under the Actions select View Java).


Delete the corrupted Java file, and restart the server then the section should work fine. But there maybe an exception where the corruptions may still occur.
