Hi
I've never really using binding much, and just ran into a problem which I hope
you guys might help me with (even if it isn't a seam issue).
I have a table which is backed by a bean in a long running conversation, when I
use a datatable defined by XHTML it works fine.
But when I switch to using binding for the datatable I have some problems.
When using the datascroller for moving to a new page of the data table I get
this error (this works when not using binding with the same backing bean):
| SEVERE: JSF1054: (Phase ID: RESTORE_VIEW 1, View ID:
/jsf/sdb/binding.xhtml) Exception thrown during phase execution: [EMAIL
PROTECTED]
| 2008/02/11 09:57:13,194 =========== RESTORE_VIEW 1 Time spent = 0 seconds

com.sun.facelets.el.TagValueExpression.setValue(TagValueExpression.java:95)
| at
com.sun.faces.lifecycle.RestoreViewPhase.doPerComponentActions(RestoreViewPhase.java:240)
|
Why is it that my backing "sdb" bean resolves to null when I use binding?
Backing bean:
| @Name("sdb")
| @Scope(ScopeType.CONVERSATION)
| public class SingleDealBrowser implements Serializable{
|
| // cut
| private List<PositionDisplayWrapper> allPositionWrappers;
|
| private HtmlDataTable bindingDataTable = null;
|
| @Create
| public void init(){
| System.out.println("SDB init()");
| if(!conversation.isLongRunning()){
| conversation.setDescription("SDB " +cpty +"," +cptyGroup +","
+expType);
| //Lets promote it into a long running one
| boolean status = conversation.begin();
| System.out.println("Tried to begin a long running conversation,
status=" +status);
| }
|
| runSearch();
|
| }
|
XHTML snippet :
| <ui:define name="posListing">
| <rich:dataTable id="posListingTable"
| binding="#{sdb.bindingDataTable}"
| value="#{sdb.allPositionWrappers}"
| style="width:100%;">
| </rich:dataTable>
| </ui:define>
|
Cheers,
Micke
