I have UI screen with multiple rows of data - each row should have a tree component - which on click shall lazily load it's children
***** page *********
<property name="treeState" persist="session" initial-value="ognl:new java.util.HashSet()"/>
<component id="tree" type="tacos:Tree">
<binding name="contentProvider" value="new com.pennmutual.csc.pages.TransactionTreeContentProvider(currentTrans[tranIndex].transType,currentTrans[tranIndex].details)"/>
<binding name="value" value="item"/>
<binding name="state" value="treeState"/>
<binding name="nodeLinkAjax" value="ognl:false" />
</component>
***** page *********
I am creating TreeContentProvider for each row - and data is read from collection which is in session.
When I click on plus sign - nothing happens - plus sign does not expand . Additionally if I just do,
***** page *********
<property name="treeState" persist="session" initial-value="ognl:new java.util.HashSet()"/>
<component id="tree" type="tacos:Tree">
<binding name="contentProvider" value="contentProvider"/>
<binding name="value" value="item"/>
<binding name="state" value="treeState"/>
<binding name="nodeLinkAjax" value="ognl:false" />
</component>
//there is getContentProvider
// there is member
// private ITreeContentProvider CONTENT_PROVIDER = new TransactionTreeContentProvider("Parent","someparam");
***** page *********
in this case plus sign works ,
so I have 2 questions -
1) Has any one implemented tree using multiple content providers ?
2) How to manage the state of tree in that case ?
if any one can suggest any clues or has sample source code to share - that shall be of g8 help.
Thanks
