can't show a Set in dataTable (JSF)

Hello,

i have a problem and need your help.

follow:
i had a object A with a set of objects B and that will be loaded completely
by hibernate. hibernate presents a collection of objects A.

class B {
int id;
String description;
//getter and setter
}

class A{
int id;
String description;
Set<B> listOfBs;
//getter and setter
}

my jsp page with JSF tags using <h:dataTable for illustrate the collection
comes from hibernate. at moment i can show all description from object A. i
can't access or show the description of object b on my screen. an problem
with lazy-loading by hibernate are solved and the objects will loading
completely. i'm an newbie at JSF and my main problem is finding the correct
statement for present 'description' of B's.

the following table should appeared:
---------------------------------
| a1.description | b1.description |
| a1.description | b2.description |
---------------------------------
| a2.description | b1.description |
---------------------------------

<h:dataTable ....>
<h:column>
<f:facet name="header">
<h:outputText value="#{msgs.a_description}" />
</f:facet>
<h:outputText value="#{record.description}" />
</h:column>
...
<h:column>
<f:facet name="header">
<h:outputText value="#{msgs.b_description}" />
</f:facet>
// statements for show descriptions
from object B . <----------------------
</h:column>
...

i haven't an idea and can't find a solution for my problem.

thank you very much for answers.

best regards
Michael
