JSF only calls getters but never setters Composite Component - jsf

Question

I have been asked to write a JSF component that handles results paging. The component takes in a bean that implements an interface. At runtime, the getter methods are called but never the setters. Here is the code
<cc:interface>
<cc:attribute name="pagableResultsBean" />
</cc:interface>
<!-- Question: We can't have a form inside of a form. Do we ecapsulate form operations here or
should the client handle them? -->
<cc:implementation>
<c:set var="pagableResultsBean" value="#{cc.attrs.pagableResultsBean}" />
<div
style="background-color: #F0F3FA; border: 1px solid #ABABAB; height: 25px; margin: 0px; padding: 2px 8px; position: relative; vertical-align: middle;">
<h:panelGroup>
<div style="float: left; width: auto;">
Showing Results <h:outputLabel value="#{pagableResultsBean.showingRecordMin}" /> - <h:outputLabel value="#{pagableResultsBean.showingRecordMax}" /> of
#{pagableResultsBean.totalRecordsNum} Results per Page:
<h:selectOneMenu value="#{pagableResultsBean.resultsPerPage}" onchange="$j(document).find('.pageBarSubmitBtn').click();">
<f:selectItems value="#{pagableResultsBean.resultsPerPageItems}" />
</h:selectOneMenu>
</div>
<div style="float: right; width: auto;">
Showing Page #{pagableResultsBean.currentPageNum} of #{pagableResultsBean.totalPagesNum} Jump
to Page
<h:selectOneMenu id="_pagesMenu" value="#{pagableResultsBean.currentPageNum}" onchange="$j(document).find('.pageBarSubmitBtn').click();">
<f:selectItems value="#{pagableResultsBean.resultsPerPageItems}" />
</h:selectOneMenu>
<h:commandLink style="position: relative; top: 3px;" action="#{pagableResultsBean.goToFirstPage()}">
<h:graphicImage value="/images/arrow-first.gif" />
</h:commandLink>
<h:commandLink style="position: relative; top: 3px;" action="#{pagableResultsBean.goToPreviousPage()}">
<h:graphicImage value="/images/arrow-previous.gif" />
</h:commandLink>
<h:commandLink style="position: relative; top: 3px;" action="#{pagableResultsBean.goToNextPage()}">
<h:graphicImage value="/images/arrow-next.gif" />
</h:commandLink>
<h:commandLink style="position: relative; top: 3px;" action="#{pagableResultsBean.goToLastPage()}">
<h:graphicImage value="/images/arrow-last.gif" />
</h:commandLink>
</div>
<h:commandButton style="visibility: hidden;" styleClass="jsfHidden pageBarSubmitBtn"/>
</h:panelGroup>
</div>
</cc:implementation>
This is the interface that the backing bean implements:
public interface PagableResults {
public int getShowingRecordMin();
public int getShowingRecordMax();
public ResultsPerPage getResultsPerPage();
public void setResultsPerPage(ResultsPerPage rpp);
public int getCurrentPageNum();
public void setCurrentPageNum(int pageNum);
public int getTotalPagesNum();
public int getTotalRecordsNum();
public List<SelectItem> getResultsPerPageItems();
public List<SelectItem> getResultsPagesItems();
public void goToFirstPage();
public void goToLastPage();
public void goToPreviousPage();
public void goToNextPage();
}
And here is the snippet where the control is used
<h:form>
<ndar:pagingBar pagableResultsBean="#{pageBean}" />
</h:form>
Can anyone see any reason why only the getters get called and not the setters?

Answer 1

As you seem to use c:set from the JSP JSTL Core Tag Library, this might not work well with the JSF and especially the JSF Composite Component system.
Have you tried to replace all instances of pagableResultsBean with cc.attrs.pagableResultsBean as this would eliminate one possible reason of the error?
Also, put a Debugger on the set-method you think is not getting called - and verify whether it is really not called or just the html result looks like.

Also make sure to have a h:messages tag to the jsf to make sure JSF tells you of a possible conversion-error.
