Inconsistent stack height 1 != 0

Classic Servoy
1

Hi guys,

since this week we have an unusual problem with starting up a client. We get the following error. And the client stops in its tracks.
I must mention that we are still using Servoy 3.5.10
I hope someone has encountered the same problem somewheer.
Thankx in advance

i guess that is a very large js method that generates an illegal class…
you could try to set the system.property.servoy.disableScriptCompile=true on the admin pages to disable script compile.

OK…we started checking large method we’ve changed in the past week. And we found one.
Allthough this method is not particularly large…172 rows…I changed 1 thing
tekst += ‘\r\n[staatszaak]\r\nWAARDE=’ + (dataset.getValue(1,28) == 1) ? ‘WAAR!’ : ‘ONWAAR!’ ;
into
tekst += ‘\r\n[staatszaak]\r\nWAARDE=’ + ((dataset.getValue(1,28) == 1) ? ‘WAAR!’ : ‘ONWAAR!’ );

I find it very hard to believe that this caused the problem…but hey…it works now…

Your tip send us on the right way…thankxxxx
