How to fix "Must be literal" error when using a4j:keepAlive tag?

Question

Hi everybody,
When I use <a4j:keepAlive> tag of Richfaces like this:
<a4j:keepAlive beanName="#{templateController.currentType}"/>I got the an error like this:
/templates.xhtml @20,91 <a4j:keepAlive beanName="#{templateController.currentType}"> Must be literalIn my class, I have declared as:
class TemplateController{
    private TemplateType currentType;
    public void setCurrentType(TemplateType type) {
    public TemplateType getCurrentType() {
}I implemented as guide from Richfaces document but don't know why this happened.
Could anyone tell me why? Please help me to fix it.
I really appreciate it,
Ringo

No, the error message says that the value must be a literal and thus not an EL. I don't know anything about Ajax4jsf (you're in the wrong place to ask questions about it, rather use the forums of the Ajax4jsf manfacturer at jboss.com), but the attributename and errormessage together makes it logical to put just the raw managed bean name in there. If this is not what you're after, then just consult their documentation and forums at jboss.com.
