BlazeDS IE8

Lauro Becker
Hi,

When I test my SWF in IE8 I get a NPE:
java.lang.NullPointerException

For some reason sessionHolder is null.

Anyone already faced this problem?

Thanks!

Re: BlazeDS IE8

We see this same stack trace (from NPE) in both Chrome and Firefox.  I don't think it's a browser issue, but rather some sort of plugin problem.  We're running Grails 1.3.7 with BlazeDS 2.0 and Spring Security 1.2.7.1.  Here's what I think is the relevant portion from our BuildConfig.groovy:

        runtime(':blazeds:2.0'){
            excludes ('spring-security-acl', 'hibernate', 'tomcat', 'spring-security-core')
        }
        runtime(':spring-security-acl:1.1'){
            excludes ('spring-security-core')
        }
        runtime(':spring-security-core:1.2.7.1'){
            excludes('release', 'svn')
        }

If anybody could shed some insight into this issue, we'd very much appreciate it.
