Tree (Single Selection) - Datatable - CommandButton

[diegoloro]

Hi all,

I'm using:
mojarra-2.1.1
primefaces-3.0.M1
glassfish 3

In my page I use a Tree, when clicking a node I populate a Datatable that has a CommandButton in every row.
That's the page code:

Code: Select all

 <h:form id="form1">
                <table>
                    <tr>
                        <td>
                            <p:panel>
                                    <p:tree id="tree" value="#{MenuController.root}" update="tabProdotto" var="node" selectionMode="single" nodeSelectListener="#{MenuController.loadProductTable}">
                                        <p:treeNode>
                                           <h:outputText value="#{node.name}"/>
                                        </p:treeNode>
                                    </p:tree>
                            </p:panel>
                        </td>
                        <td>
                             <p:panel>
                                     <table>
                                        <tr>
                                            <td>
                                                <p:dataTable id="tabProdotto" var="prodotto" value="#{MenuController.products}" paginator="true" rows="10" selection="#{MenuController.row}" selectionMode="single">
                                                    <p:column headerText="#{msg.name}">
                                                        <h:outputText value="#{prodotto.name}" />
                                                    </p:column>
                                                    <p:column headerText="#{msg.add}">
                                                        <p:commandButton value="#{msg.add}" actionListener="#{MenuController.add}" />
                                                    </p:column>
                                                </p:dataTable>
                                            </td>
                                        </tr>
                                    </table>
                             </p:panel>
                        </td>
                    </tr>
                </table>
                </h:form>

All goes right, the tree works populating the Datatable on node click, but when I click the CommandButton on the row I get an Exception:

Code: Select all
