jsf 2 - How to call the same method after every include of a .xhtml page in JSF? -


i have following part of .xhtml page:

<ui:composition template="./templates/template.xhtml"> <ui:define name="maincontent">      <ui:include src="include/includeableeditor.xhtml">         <ui:param name="includeparam" value="myclass" />      </ui:include>        <ui:include src="include/includeableeditor.xhtml">         <ui:param name="includeparam" value="yourclass" />     </ui:include>  </ui:define>

in "includeableeditor.xhtml" want call method after included (in case should happend 2 times).

now tried solve this: (metadata tag part of includeableeditor.xhtml)

<f:metadata>     <f:event type="prerenderview" listener="#{editor.onload}" />     <f:attribute name="textfieldid" value="#{includeparam}" /> </f:metadata>

the problem:

the method being called once. should called 2 times. once parameter "myclass" , once "yourclass".

do have suggestions?

thanks lot!

there can 1 <f:metadata> in entire view , must in top level view. unlike e.g. <f:view>, don't "extend" each other , others ignored.

you don't need here. it's necessary whenever need attach <f:viewparam> and/or <f:viewaction> specific view. <f:event> doesn't require <f:metadata>. hooked parent uicomponent. during jsf 2.0/2.1 ages (when <f:viewaction> didn't exist) being abused have hook invoke listener after <f:viewparam> values being set. it's self-documentary purposes being placed in same <f:metadata> <f:viewparam>s are.

so, rid of it. 

<f:event type="prerenderview" listener="#{editor.onload(includeparam)}" />

that said, postaddtoview better event hook on. , avoid "duplicate component id" errors on place later on, consider wrapping in <f:subview> or making composite.
