Get id of parent naming container in template for in render / update attribute
el, jsf-2, naming-containers, primefaces
Solution
Ugly, but this should work out for you:
<p:commandButton action="..." update=":#{component.namingContainer.parent.namingContainer.clientId}:form2:table2" />
As you're already using PrimeFaces, an alternative is to use `#{p:component(componentId)}`, this helper function scans the entire view root for a component with the given ID and then returns its client ID:
<p:commandButton action="..." update=":#{p:component('table2')}" />
Problem
I have a template and in its Definition I use several forms and buttons. The problem is the definition (define) xhtml file does not know the component hierarchy. And for example I want to update the element "table2" in a different form in the same define file. Template Insert: ``` <p:tabView id="nav"> <!-- nav --> <ui:insert name="content_nav">content navigation</ui:insert> </p:tabView> ``` defines the first level of my hierarchy "nav" Template define: ``` <ui:define name="content_nav"> <h:form id="form1"> <!-- nav:form1 --> <h:dataTable id="table1"/> <!-- nav:form1:table1 --> <p:inputText value="#{bean.value}"/> <p:commandButton action="..." update="nav:form2:table2"/> </h:form> <h:form id="form2"> <h:dataTable id="table2"/> <!-- nav:form2:table2 --> <!-- other elements --> </h:form> </ui:define> ``` In my define part I don't want to know "nav"! How can I do this? or how can I move one naming component upwards?, or save the highest parent complete id in a variable? sometimes i saw something like: ``` update=":table2" ``` But I could not find any informations about this?, the JavaEE 6 documentation just mentions the @ keywords.
