Not sure this is the plugin actually...
I have seen quite a lot of Exceptions (running Servoy from Eclipse0 when updating the field - these are coming from the java HtmlEditorKit used by Servoy for HTML_AREA fields...
Maybe you could output a flag to confirm that the plugin returned the value and see if the lock occur before or after the value is sent back...
From the stack trace here it seems that this is DBGP (javascript Servoy debugger) which is locked.

But these are not trapped by Servoy because they happen in a different thread.
And they happen AFTER the plugin has sent back its return value.
I must admin it's only recently that I have seen these exceptions in Servoy (using 5.2.7i here in my case), but it definitely smells like a new Servoy issue to me.

okay, lets call it a Servoy Dev issue then and not the plugin.

I'm going to follow that, and probably report to Servoy...
Basically as soon as you you have more than 20 tweets in the HTML_AREA (the threshold is not that clear cut), you get one of these exceptions for each new line you add.
I think there is something wrong in com.servoy.j2db.util.FixedHTMLEditorKit, I don't think it was there before, will need to check the history on that unless it's coming from yet another class called by this one.
Maybe one thing to try in the sample solution though would be to fill a temp String variable and then fill the "tweets" form variable in one go?

I updated the sample solution to use a variable to fill the form-variable in one go.

Yes, and guess what: no more EmptyStackException
I will try and do a simple case for Johan on this one.
