    Problems getting jsp:include to work

    David M. Karr Newbie

      JSF 1.1, RichFaces 3.1.3.

      I have a tabPanel where some of the tabs will work identically, such that they will have the same fields, but each instance will go to a different array entry in the backing bean. I've tested and verified the functionality "inline" in the main page, but I think it would be better if I moved the content of the tab into an include file and use "jsp:include" with a parameter from the main page.

      On the first try, I'm not even using the passed parameter in the include file (just using a default index of 0 for now). I'll integrate that when everything else is working.

      When I first tried it, my "jsp:include" looked like this:

      <f:subview id="propertysubview0">
       <jsp:include page="/propertyTab.jsp">
       <jsp:param name="propertyIndex" value="0" />
       </jsp:include>
      </f:subview>

      When I ran this, it gave me an error like:

      Error testing property 'propertyID' in bean of type null

      I then realized that perhaps my include URI should be "/faces/propertyTab.jsp" (that's the mapping to my Faces Servlet). After I made that change, I instead got the following exception:

      java.lang.NullPointerException
       at com.sun.faces.el.ValueBindingImpl.(ValueBindingImpl.java:98)
       at com.sun.faces.application.ApplicationImpl.createValueBinding(ApplicationImpl.java:292)

       at org.richfaces.taglib.TabTag.setProperties(TabTag.java:568)

      My included JSP looks like this:
      <%@ taglib uri="https://ajax4jsf.dev.java.net/ajax" prefix="a4j"%>
      <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>

      <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
      <f:subview id="includedPropertyPage">
       <h:panelGrid id="propertyPanelGrid" columns="3">
       <h:outputText id="propertyIDOut" value="Property ID"/>
       <h:inputText id="propertyIDIn"
       value="#{ratingRequest.propertyList[0].propertyID}">
       <a4j:support id="propertyIDInSupport" event="onchange" reRender="propertyTable"/>
       </h:inputText>
       <rich:message for="propertyIDIn" showDetail="true"/>
       <h:outputText id="valueOut" value="Value"/>
       <h:inputText id="valueIn"
       value="#{ratingRequest.propertyList[0].value}">
       <a4j:support id="valueInSupport" event="onchange" reRender="propertyTable"/>
       </h:inputText>
       <rich:message for="valueIn" showDetail="true"/>
       </h:panelGrid>
      </f:subview>
