Hi,

A programmer in our company is reporting that a messageBox in their v8 PLSQL Developer appears continuously with this text in it:

"Control 'dxDockBrowserPanel' has no parent window"

this guy tell me that can't do much longer because with any action that try to execute in the IDE the same messageBox is fired.

this is the content of the file plsqldev.elf:

Has anyone faced this problem?.

Any help will be great. Thanks.

 
We're currently looking into this. As a workaround, reset the docking layout to default by deleting the following registry sections:

HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Docking
HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Docking2
HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Docking3

 
Hi Marco,

The workaround has fixed the bug. The messsageBox is not fired anymore.

Thanks a lot, I will be looking for a path to v8 in the future.

Grettings.
