So map the FormCategory as an entity.

Thanks muir,
but
FormCategory is already mapped as an entity. I am giving code snippet from my xhtml

<tr style="height:30px" >
<td align="right" width="35%" class="dvtCellLabel">category</td>
<td align="left" width="65%" class="dvtCellInfo">
<h:selectOneMenu value="#{forms.formsCategory}" class="detailedViewTextBox" >
 <s:selectItems value="#{formsManager.refreshedFormCategories}"
 var="formsCategory"
 label="#{formsCategory.categoryName}"
 noSelectionLabel="Please Select..."/>
 <s:convertEntity />
</h:selectOneMenu>
</td>
</tr>

I think i have problem with

<s:convertEntity />

Any suggestions are welcome!!

No, I think you have a problem with your mappings - are you *sure* that class is mapped as an entity? Check in the entity mappings at startup and post code!

Any suggestions are welcome!!
