Hmmm... where is performAction?
I have the following in Application:
public WOResponse handleActionRequestError(WORequest aRequest,
Exception exception, String reason, WORequestHandler aHandler, String
actionClassName, String actionName, Class actionClass, WOAction
actionInstance) {
if (actionInstance != null) {
if(actionInstance.context().hasSession())
actionInstance.context().session().terminate();
com.hb.pages.Home home = (com.hb.pages.Home) pageWithName
("Home", actionInstance.context());
return home.generateResponse();
} else {
return handleException(exception, null);
}
}
this traps the error and sends them back to the homepage, however, it
freezes the instance.

Anyone have any obvious ideas why a bad directAction would freeze

I noticed this from a bad link going to a non-existent DirectAction.
It might vary by version :-(, but in at least some versions, if
performAction throws and there is a session, the session will not
get checked in which deadlocks that session. If the app is not
dispatching requests concurrently, that will deadlock the entire app.
The solution to that one is to wrap performAction in a try..catch
block and pass the exception off to Application.handleException.
