Re: SV: Re: basic dialog nullpointerexception

Hi.

After I switched my local project to another version (different
workspace), it indeeded stopped working with 5.5.23. But it worked
before with 5.5.23. I don't know what it blew up.

So that means, listeners in tlds only work up to tomcat 5.5.17? But it
didn't work out with my 5.5.17 version. Strange thing. Meanwhile I think
perhaps it's a problem with eclipse wtp and tomcat. Never tried it with
tomcat standalone. Did you?

BTW: I'm using Java5.

regards,
Veit
