Struts 2 Select tag issue

[Joe Harry]

Guys,

I have an object in session and I want to access this object and use it for the s:select tag rendering:

<s:select label="Go To Question: " id="#session.examObject.allQuestionIds" list="#session.examObject.allQuestionIds" listKey="key" listValue="value" />

examObject is what I have in my session scope and the allQuestionIds is a Map < Long, Long > defined in my ExamObject. When I used this, I got the following error:

Messages: 	

    tag 'select', field 'list': The requested list key '#session.examObject.allQuestionIds' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name}
    tag 'select', field 'list': The requested list key '#session.examObject.allQuestionIds' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]

I'm sure that I'm missing the basics. But help please!

Any ideas?

Why is it not possible to read a Map from session?

Ok. It worked. The problem was my Map was null and when I filled some values, it worked.
