controller.find() makes method stop in it's tracks

I have the oddest thing happening at a customer.

Their solution does a find/seach in a method. So far nothing special.
But when it does controller.find() it stops. The statusbar shows the “press F3 or return” text like you manually invoked the find.
The in the editor the script looks canceled. Any breakpoints after the controller.find() are not triggered. But the stop/pause buttons are disabled and the run button is enabled like the script doesn’t run anymore.

Also switching to design mode doesn’t make you go into design mode. You have to switch twice to design mode and back to be able to get out of this.

Anyone seeing this ?
Any reason why this would happen? (or is it a bug..)

This is with the latest 2.2.1rc-330 release. OS is Win2K.

I did some more testing.
On Mac OS X with java 1.5 it works fine.

The windows machine uses Java 1.4.2_05-b04 (Windows 2000)

I ran a stacktrace but I have to type it here (I wish vnc had copy/paste support).

etc...

I think it has to do with the fact that the leatest build was (accidently!) build with java 1.5. I am not sure!
You can try upgrading the 2000 client to java 1.5!

Wouldn’t that make it impossible to launch developer/server in the first place?
It does for the mac. No way I can launch it with Java 1.4.x.
So I suspect it’s something else.

Let me add that this behavior came directly after I updated them from (a working) 2.2.1 beta to the public 2.2.1rc1.
So it seems that something has changed in Servoy 2.2.1rc1 to cause this behavior.

They need this 2.2.1 version to be able to use the images plugin so moving back to 2.2 is not an issue.

Jan/Johan/Sebastiaan any ideas?
