I have a built in Variable resolver / function mapper to resolve some EL in code. When my managed EL rules are not satisfied I wold like to delegate the EL interpretation to the default page mechanism. I retrieve the Page's FunctionMapper object with this code: component.getPage().getFunctionMapper(). However, sometimes component's page is null and the mechanism fails. Any suggestion on how to reach the current FuncionMapper?

Hi,

if the page is null, it means the component has not been attached a page yet and the function mapper cannot be determined yet safely. As the component could be attached to any page afterwards having different variable scopes.

I suggest you wait with accessing a functionMapper until the component is attached to a page (e.g. by overriding onPageAttached)
