HI,

I am writing an application to update Frontbase from FileMaker.
I use AjaxLongResponse in my interface to see the progress in the browser.
But I always get an error:
<er.ajax.AjaxRequestHandler>: Exception occurred while handling request:
java.lang.IllegalStateException: Illegal Lock usage: unlocking thread not owner. [2008-02-04 19:25:12 CET] <WorkerThread0> java.lang.IllegalStateException: Illegal Lock usage: unlocking thread not owner. at com.webobjects.foundation.NSRecursiveLock.unlock(NSRecursiveLock.java: 207) at com.webobjects.eocontrol.EOEditingContext.unlock(EOEditingContext.java: 4720)

        at java.lang.Thread.run(Thread.java:613)

Is there a way to avoid this? Or am I impplementing this wrong?

I can see also next error):

Another Exception  occurred while trying to clean the application:
