Hi,
I need to use the nested table option for display tags. Below is the current
code/setup which does not throw any errors but only displays the parent
table or the main table data but not the nested one.
Not sure what I am missing...I am using DisplayTag 1.2.
I have an object with a nested collection (One to many relation within the
same table - An asset can be child of another asset).
Here is my displaytag code
<display:table name="assetList" id="parent" requestURI="/listAssets"
pagesize="10" >
<display:column property="assetAddress" title="assetAddress" />
<display:column property="assetVersion" title="assetVersion"/>
<display:column property="comments" title="Comments" />
<display:table name="${parent.assetsCollection}" id="ad">
<display:column property="assetAddress"/>
<display:column property="assetVersion" />
<display:column property="comments" title="Comments" />
</display:table>
</display:table>
Here is the entity class code:
