[richfaces-issues] [JBoss JIRA] Commented: (RF-7354) ELContextWrapper do not delegate property ELContext.resolved

[Danny Worm (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-7354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12471382#action_12471382 ] 

Danny Worm commented on RF-7354:
--------------------------------

I've found a workaround.

I extend ELContextWrapper with this method's.

    @Override
    public boolean isPropertyResolved() {
        return parent.isPropertyResolved();
    }
    
    @Override
    public void setPropertyResolved(boolean resolved) {
        parent.setPropertyResolved(resolved);
    }

And patch the jar with the new class file.

It seems to work.

Kind regards,
daworm

> Class<?> type = expression.getType(new ELContextWrapper(initialELContext, capturingELResolver));
> While the searchroutine for getType() look up all resolver, the code stops at the com.sun.faces.el.DummyPropertyResolverImpl - Resolver.
> This resolver set the property "resolved" in this line: (DummyPropertyResolverImpl:93)
> FacesContext context = FacesContext.getCurrentInstance();
> context.getELContext().setPropertyResolved(false);
> The searchroutine stops because the property isnt set to false in the ELContextWrapper object and the Wrapper do not delegate the property to the origin ELContext inside. 
> How can I solve this?
