7.3.1 [functionName] is not a function ERROR

Classic Servoy

Guys,

This is a really weird one. I have a form that has a long method that has been working perfectly for 3 years. It works fine in Developer, but when deployed it gets this error:

Servoy is telling you what’s wrong:

Program too complex

:lol: :lol: :lol:

sorry… :wink:
No clue why this happens

I would try blowing out the repository database and uploading your solution fresh.

Mozilla tells that. ;)

Mozilla says also:

(out of locals)

This refers to the local slots in the Rhino Javascript. See here: https://github.com/mozilla/rhino/blob/m … degen.java
Also a search reveals this snippet from here: http://permalink.gmane.org/gmane.comp.mozilla.devel.jseng.rhino/1168

Yes, the JVM has a limit of 256 local slots, where a double/long
consumes two slots. Rhino could presumably be smarter about saving and
restoring locals in an object to get past this limit, but the
complexity of that hasn’t yet been justified as not too many people
hit this limit.

As far as I can gather local slots are the underlying storage mechanism for local variables.
It is possible that your code being lengthy has too many.
Try breaking methods/functions into smaller pieces.
Just my suggestion…

Hi Tom,

Thanks for that! It is a pretty long method with many variables. It’s strange that this worked just fine in all previous versions of Servoy… :)

I appreciate your tip!

Bob

if you keep running in interpreted mode then this will work fine also in de client
(developer and web always do that)
you can set a system property: system.property.servoy.disableScriptCompile=true through the admin page so that also the smart client doesn’t compile to byte code.
