RF4 Wizard page problem - replacing panel contents leads to FacesException...ClassCastException: StateHolderSaver cannot be cast to Object

[ssamayoagt]

I'm writing a wizard page which dynamically changes the content of panel but not only the content is bad rendering but when post is issued I got the following exception:

GRAVE: javax.faces.FacesException: Unexpected error restoring state for component with id fpaso:t1:s1:j_idt50:filter.  Cause: java.lang.ClassCastException: javax.faces.component.StateHolderSaver cannot be cast to [Ljava.lang.Object;.

This is the partial part of the wizard where panel content is replaced:

				<td width="80%" valign="top"><rich:panel id="paso"
					style="height:#{ppAsistenteNormal.pasoInicial ? 500 : 450}px;">
					<f:facet name="header">#{ppAsistenteNormal.pasoActual.nombre}</f:facet>
					<table width="100%">
						<tr>
							<td><ui:include
								src="/pp/pago/normal/paso#{ppAsistenteNormal.pasoActual.pasoId}.xhtml" /></td>
						</tr>
					</table>
				</rich:panel></td>

Problem came when panel is replaced and contains a rich:dataTable or rich:extendedDataTable: those components aren't rendered correctly.

When form is posted I get the above exception.

Just guessing, it seems that since is ajax replacement not all java script nor css is retrieved. I just looked for LoadScriptStrategy in RF4 but is no longer available.

So, if I cant find a way to get ALL css and js preloaded (that may not solve the problem anyway) seems that I will have to go back to  JSF 1.2 with RF3.3 or use another component library.

Regards.

UPDATE:

Exception go away when I remove a <a4j:ajax> from inputs and,  at differentpage, own composite component.

I have no clue why those components works well if page is "full" rendered but fails when is ajax rendered.

FWIW my composite componet is:

<composite:interface>

          <composite:attribute name="popup" />

          <composite:attribute name="hint" />

          <composite:attribute name="filtered" default="false" />

</composite:interface>

<composite:implementation>

          <a4j:commandLink id="filter">

                    <rich:componentControl event="click" target="#{cc.attrs.popup}"

                              operation="show">

                              <a4j:param id="event" name="event" value="event" noEscape="true" />

                              <rich:hashParam>

                                        <a4j:param id="top" noEscape="true" name="top"

                                                  value="jQuery(#{rich:element('filter')}.parentNode).offset().top + jQuery(#{rich:element('filter')}.parentNode).height()" />

                                        <a4j:param id="left" noEscape="true" name="left"

                                                  value="jQuery(#{rich:element('filter')}.parentNode).offset().left" />

                              </rich:hashParam>

                    </rich:componentControl>

                    <h:graphicImage library="img" name="filter12.png"

                              rendered="#{!cc.attrs.filtered}"

                              style="vertical-align: middle;border:0" alt="#{cc.attrs.hint}"

                              title="#{cc.attrs.hint}" />

                    <h:graphicImage library="img" name="filtered12.png"

                              rendered="#{cc.attrs.filtered}"

                              style="vertical-align: middle;border:0" alt="#{cc.attrs.hint}"

                              title="#{cc.attrs.hint}" />

          </a4j:commandLink>

</composite:implementation>

Bad rendering stills.
