Cause

Root cause is on TCF functionality.

The same problem occurs when viewing menu View Tree as described in Note 787290.1: View Tree Button Not Working.

Solution

1. Navigate to System Administrator -> Application -> Menu
2. Query a Menu and press the View Tree button
3. If this doesn't open the new window, then this is the same case as described on Note 787290.1: View Tree Button Not Working and you need to follow the same solution.

Cause

This issue is caused by an inconsistent java signer state. Basically, it seems some files were signed using a different signature to others

Solution

1. Use the ADADMIN tool to regenerate jar files with option "force" set to "Y"

2. Stop and start middle tier services

3. Re-test the issue
