10:48 a.m.
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)
