Description Pablo CLA 2011-07-12 06:32:16 EDT 
Build Identifier: 20100617-1415

I can't find where it fails. I am working at this about 3 days.
I get this calendar for my web from dhtmgoodies and this have a nullpointexception that i can't find. I don't know where i need to go to request for help. It isn't a bug of Eclipse, it's a problem of the code i think.
Please give a watch on it, i don't want to disable the JSValidator.
A lot of thanks for all.

Reproducible: Always

Steps to Reproduce:
Simply, put that js in a dynamic web project and when building... BOOM!

Thank you another time more.

You seem to be using Helios.  Please retry it with Indigo.
Comment 2 Chris Jaun CLA 2011-07-13 16:35:46 EDT 
I can reproduce the following error in 3.2.5. Is this what you were seeing, Pablo?

Comment 3 Pablo CLA 2011-07-15 06:42:22 EDT 
Yep, i have that.

I just now try it with Indigo and I get the same Exception.

I dont know how to do for no disble JSValidator.

Anyone see something wrong?
Thanks for ur time.
Comment 4 Pablo CLA 2011-07-20 03:03:28 EDT 
I think i solved it.

I get out the switch/case sentences and it will work properly.

I dont know why but it is not getting the exception.

Thank you for all.
