Component javax.faces.component.UIViewRoot is no ValueHolder

[esource]

I'm getting this error:

Component javax.faces.component.UIViewRoot is no ValueHolder, cannot set value

11:33:24,062 User:admin ERROR [shared_impl.taglib.UIComponentTagUtils] Component
javax.faces.component.UIViewRoot is no ValueHolder, cannot set value.

What does this mean?

I have a .jsp in a dialog that calls a method in the backing bean:

<h:dataTable binding="#{DialogManager.bean.dataTable}" value="#{DialogManager.bean.dataList}" var="dataItem">
    <h:column>
        <f:facet name="header">
            <h:outputText value="ID" />
        </f:facet>
        <h:commandLink value="#{dataItem.id}" action="#{MyBeanDialog.editDataItem}" />
    </h:column>
 
    <h:column>
        <f:facet name="header">
            <h:outputText value="Name" />
        </f:facet>
       <h:outputText value="#{dataItem.name}" />
    </h:column>
 
    <h:column>
        <f:facet name="header">
            <h:outputText value="Author" />
        </f:facet>
        <h:outputText value="#{dataItem.author}" />
    </h:column>
</h:dataTable>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

in my backing bean dialog:

public class MyBeanDialog extends BaseDialogBean {
…
    public String editDataItem() {
 
       if (logger.isDebugEnabled()) logger.debug("editDataItem");      
 
        // Get selected MyData item to be edited.
        dataItem = (customNode) dataTable.getRowData();
 
        // Store the ID of the data item in hidden input element.
        dataItemId.setValue(dataItem.getId());
 
        return "edit"; // Navigation case.
    }   
…

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

in my faces-config.xml:

      <navigation-case>
           <from-action>#{MyBeanDialog.editDataItem}</from-action>
           <from-outcome>edit</from-outcome>
           <to-view-id>/jsp/extension/dialogs/edit-data-item.jsp</to-view-id>
       </navigation-case>  
‍‍‍‍‍‍‍

in edit-data-item.jsp:

<h:panelGrid>
    <h:outputText value="ID" />
    <h:outputText value="#{MyBeanDialog.dataItem.id}" />
 
    <h:outputText value="Name" />
    <h:inputText value="#{MyBeanDialog.dataItem.name}" />
 
    <h:outputText value="Author" />
    <h:inputText value="#{MyBeanDialog.dataItem.author}" />
</h:panelGrid>

‍‍‍‍‍‍‍‍‍‍‍‍‍

When clicking on

 <h:commandLink value="#{dataItem.id}" action="#{MyBeanDialog.editDataItem}" />
‍‍

edit-data-item.jsp appears on a screen blank.

What is causing the error? Why aren't the jsf components appearing on the screen?

It means you are missing <f:view></f:view> tags around your jsf tags.  Check your code once again.  It's a jsf issue not alfresco.

Yes, thank you.  It resolved the error.  Another question.  Currently, when clicking on:

<h:commandLink value="#{dataItem.id}" action="#{MyBeanDialog.editDataItem}" />
‍‍‍

edit-data-item.jsp appears, but it covers the entire browser display.  What do I have to do so that it displays within the Dialog?
