Valuechange listener works only for some components in page

Question

This is a portion of XHTML, which is that included into the page. It hash 2 <h:selectOneRadio> which have the same listener, but only in the first case the method is called right after user changes value of radio. In the second case its triggered only when submiting the form.
*<h:selectOneRadio id="workType"*
*valueChangeListener="#{orderingPage.valueChanged}"*
*value="#{orderingPage.ordering.orderedObject.workType}"*
*layout="pageDirection">*
*<f:selectItem itemLabel="#{enums['WorkType.scan']}" itemValue="SCAN" />*
*<f:selectItem itemLabel="#{enums['WorkType.filmcopy']}"*
*itemValue="FILMCOPY" />*
*<f:selectItem itemLabel="#{enums['WorkType.papercopy']}"*
*itemValue="PAPERCOPY" />*
*<f:selectItem itemLabel="#{enums['WorkType.print']}" itemValue="PRINT" />*
*<f:selectItem itemLabel="#{enums['WorkType.readerPrinter']}"*
*itemValue="READER_PRINTER" />*
*<f:selectItem itemLabel="#{enums['WorkType.photo']}" itemValue="PHOTO" />*
*<f:ajax*
*render="scanTypesGrid copyFormatGrid copyColorGrid deliveryTypeGrid" />*
*</h:selectOneRadio>*
*<h:panelGroup id="copyFormatGrid">*
*<h:selectOneRadio layout="pageDirection"*
*value="#{orderingPage.ordering.orderedObject.copyFormat}"*
*valueChangeListener="#{orderingPage.valueChanged}"*
*rendered="#{(orderingPage.ordering.orderedObject.workType == 'PAPERCOPY') or (orderingPage.ordering.orderedObject.workType == 'PRINT')}">*
*<f:selectItem itemLabel="#{enums['PaperCopyFormat.a0']}" itemValue="A0" />*
*<f:selectItem itemLabel="#{enums['PaperCopyFormat.a1']}" itemValue="A1" />*
*<f:selectItem itemLabel="#{enums['PaperCopyFormat.a2']}" itemValue="A2" />*
*<f:selectItem itemLabel="#{enums['PaperCopyFormat.a3']}" itemValue="A3" />*
*<f:selectItem itemLabel="#{enums['PaperCopyFormat.a4']}" itemValue="A4" />*
*</h:selectOneRadio>*
Can't see anything, why also the 2nd should not be working fine. Generally in this page i have some listeners working, some not, don't know why.
thanks for help!
PS: I use primefaces 2.2.1 and jsf-api 2.1.2

Answer 1

Note that the first has an f:ajax attached to it and the second does not.
