[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-4053) Can't resolve EL Function which serialized to ViewState

[Norman Richards (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-4053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12460589#action_12460589 ] 

Norman Richards commented on JBSEAM-4053:
-----------------------------------------

Hmm...  I tried your code and it worked as expected without any exceptions.   Can you please try running from trunk and let me know if you still see the exception?  There have been some minor changes that might possibly affect classloading here.

> It seems that EL Function which serialized to ViewState can't be resolved when the object is deserialize. Because the jboss-el directly use "Class#forName(String)". The code is as follows,
> {code:title=org.jboss.el.lang.FunctionMapperImpl.java|borderStyle=solid}
>         public Method getMethod() {
>             if (this.m == null) {
>                 try {
>                     Class t = Class.forName(this.owner);
>                     Class[] p = ReflectionUtil.toTypeArray(this.types);
>                     this.m = t.getMethod(this.name, p);
>                 } catch (Exception e) {
> {code}
> I think the above code cause ClassLoader Scope Problem. "Thread.currentThread().getContextClassLoader()" should be used.
> I found the jboss-el already had utility method for "Class.forName". It's "ReflectionUtil#forName(String)" method. Please use this method.
