PropertyNotFoundException exception

[Rafa de Castro]

Surely it has been answered before but i've been looking for two days on this (also used advanced search function and didn't find anything).

I have a form that displays a dataTable and I want to display some data with checkbox on it. Similar to a webmail.

The code for the jsf is (resumed to all important parts).

 
        <h:dataTable var="document" value="#{personForm.allDocumentsBut}" binding="#{personForm.selectedDocuments}" >
   <h:column>
   [...]
   </h:column>
</h:dataTable>

The backing bean definition has a method like this (just for testing purposes) for populating the table

public List getAllDocumentsBut() {
  return new ArrayList();
}

and for the data binding

    UIData selectionTable;
 
    public void setSelectionTable(UIData theTable) {
        selectionTable = theTable;
    }
 
    public UIData getSelectionTable() {
        return selectionTable;
    }

And the (big) stack trace.

[Rajeev Ravindran]

do you have the binding methods getSelectedDocuments() and setSelectedDocuments() in your backing bean ?

Thanks,

[Rafa de Castro]

Yes. I did a copy of other tryout. The correct code of the jsp was

        <h:dataTable var="document" value="#{personForm.allDocumentsBut}" binding="#{personForm.selectionTable}" >
          <h:column>
...
          </h:column>
        </h:dataTable>

Today I solved it but can't understad why.

I changed the declaration of getSelection table and seltSelectionTable like this and everithing worked.

    HtmlDataTable selectionTable;
 
    public void setSelectionTable(HtmlDataTable theTable) {
        selectionTable = theTable;
    }
 
    public HtmlDataTable getSelectionTable() {
        return selectionTable;
    }

Can somebody undestand why? All the docs I found were with the old declaration.
