Re: Darstellung von Set-Elementen in JSF



Hello DeoXMAN,

thank you for your special note. :-)

here the translation of my previous contribution:

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
