[jbosstools-issues] [JBoss JIRA] (JBIDE-18224) Table Selection has poor performance if "Verify Database Connection" is checked in previous step

Max Rydahl Andersen commented on JBIDE-18224:
---------------------------------------------

the PR seem to just handle not validating on every keystroke but that does not have any effect for this actual issue.

Does Forge not support having different validation when on a page (i.e. partial) vs pressing next (i.e. full) to avoid doing long consuming validations ?

> If the "Verify Database Connection" *is checked* then there is very *poor performance* in the next step during tables selection on JPA: Generate Entities From Tables wizard.
> I don't understand what is going on behind the scenes - but there is for sure some communication with DB happening. Not sure if this is necessary as the list of tables is read correctly and imho the list should be just checked if there is at least one table selected. 
> It works *without performance problems* if "Verify Database Connection" was *not checked* in previous step.
