simpleTogglePanel - when rendered attribute is an EL express
I have a rich simpleTogglePanel whose "rendered" attribute is bound to a backing bean field that evaluates to a small boolean. What i want to achieve is when the rendered attribute is true the simpleTogglePanel would be shown, and hidden if false. The problem is even when the backing bean rendered value is true the simpleTogglePanel won't show. What am I doing wrong? Below is the markup and backing bean code. It would only work if i hard-coded the backing bean's rendered value to "true".
Thanks for your help.
