I am having problems with a DataModelSelection. I have an s:link in a table
column and when I execute the action, the row data is not being injected into
the DataModelSelection. What I am attempting to do is create nested tables
where an Address list is in the parent table and matching service requests are
in the child table, so there is no page navigation involved at this point.
Here is the page
<tr:table
| id="addresses_id"
| var="addressRow"
| value="#{foundAddresses}"
| rowBandingInterval="1"
| rendered="#{foundAddresses.rowCount>0}"
| rowSelection="single">
| <tr:column>
| <f:facet name="header">
| <tr:outputText
value="#{msgs['AddressList.addressNumber']}"/>
| </f:facet>
| <s:link id="viewRequests"
action="#{addressListing.findRequests}" value="View Requests"/>
| ....
Here is the SFSB
I am Beginning a conversation when the first datamodel(foundAddresses) is
populated, then ending the conversation when the second (requests) is populated
via the DataModelSelection(selectedAddress) object from the first DataModel
(foundAddresses)
