ADF 11g BC - Reactivate the "Add from Table..." button in Entity Object Overwiew Wizard

Applies to : JDeveloper 11.1.1.2

Problem description

• you are connected to database (network)
• you are able to choose the desired button
• so everything is fine, you are able to work productive

But

• you're went standby with your machine because you moved from work to homeoffice
• waking up you're machine, connecting to network you want to invoke "Add from Table...." button
  => No chance. the button is disabled! See my screenshot
• 
• -OK so first solution comes to mind. reopen the *EO.xml file
  => No change.the button is still disabled!

Fastest Solution found so far

• Open the project settings and navigate to Business compontens section
• 
• Do nothing, apply the button "OK" (not visible in screenshot)
  => the db connections seems to be reestablished or verified or what ever
• Close the EO.xml and reopen it
  => "Add from Table..." button is activated!
• => No need to restart JDeveloper. That would be another solution. But takes a lot more time if you only have an average hardware.

Failed solution approaches

• close *EO.xml and reopen it. => "Add from Table...." button is still deactivated

Open questions / improve usability suggestion

• Which circumstance leads actually to disable the "Add from Table..." button?
• It would be nice if the "Add from Table..." button would be active for ever. On Demand/Click would be reported if there is no valid database connection.

 

Have you experienced similar annoying problem? Any useful hints for the observed behaviour would be greatly appreciated.
