I am not sure from your symptoms description whether you are experiencing
browser javascript deadlock or an Application deadlock.
... for javascript browser deadlock......
- Use FireBug to see if you have javascript errors associated with the page or
upon executing the action from the JSModalWindow (which I have never used
myself)
- Try running the action temporarily from a plain WOHyperlink
- Try using AjaxModalDialog from Ajax framework instead of JSModalWindow
.... for application deadlock..... try....
- Turning on ERXEC lock tracing
- use ERXStatisticsStore to grab stack traces in middle of the problem request
- Do a dump of all thread stack traces after the app has frozen to see the
state of the threads using jstack
