Restore state failing with facelets component
I have a component that is created using the facelets tag handler API similar to the ui:component tag. I wasn't having any issue with AjaxAnywhere with it, but with A4J plugged in, I am getting an odd behavior:
java.lang.ClassCastException: java.lang.String at javax.faces.component.UIComponentBase.restoreState(UIComponentBase.java:947) at com.outlooksoft.cpm.livereport.controls.HtmlReportFilterDialog.restoreState(HtmlReportFilterDialog.java:237) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:731) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:722) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:722) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:722) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:722) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:722) at javax.faces.component.UIComponentBase.processRestoreState(UIComponentBase.java:722) at org.apache.myfaces.application.jsp.JspStateManagerImpl.restoreComponentState(JspStateManagerImpl.java:200) at org.apache.myfaces.application.jsp.JspStateManagerImpl.restoreView(JspStateManagerImpl.java:270) at org.ajax4jsf.framework.ajax.AjaxStateManager.restoreView(AjaxStateManager.java:83) at org.jboss.seam.jsf.SeamStateManager.restoreView(SeamStateManager.java:49) at org.ajax4jsf.framework.ajax.AjaxStateManager.restoreView(AjaxStateManager.java:83) at org.apache.myfaces.application.jsp.JspViewHandlerImpl.restoreView(JspViewHandlerImpl.java:231) at com.sun.facelets.FaceletViewHandler.restoreView(FaceletViewHandler.java:321) at org.ajax4jsf.framework.ViewHandlerWrapper.restoreView(ViewHandlerWrapper.java:116) at org.ajax4jsf.framework.ajax.AjaxViewHandler.restoreView(AjaxViewHandler.java:147) at org.jboss.seam.jsf.SeamViewHandler.restoreView(SeamViewHandler.java:64) at org.jenia.faces.template.handler.ViewHandler.restoreView(ViewHandler.java:263) at com.sun.facelets.FaceletViewHandler.restoreView(FaceletViewHandler.java:321) at org.ajax4jsf.framework.ViewHandlerWrapper.restoreView(ViewHandlerWrapper.java:116) at org.ajax4jsf.framework.ajax.AjaxViewHandler.restoreView(AjaxViewHandler.java:147) at org.apache.myfaces.lifecycle.RestoreViewExecutor.execute(RestoreViewExecutor.java:81) ...
My restore and save code:
@Override
public Object saveState(FacesContext context)
{
return new Object[] {
super.saveState(context),
ajaxZone,
value,
saveAttachedState(context, onAcceptListener),
saveAttachedState(context, onCancelListener)
};
}
@Override
public void restoreState(FacesContext context, Object state)
{
Object[] array = (Object[])state;
int index = -1;
super.restoreState(context, array[++index]);
ajaxZone = (String)array[++index];
value = array[++index];
onAcceptListener = (MethodBinding)restoreAttachedState(context, array[++index]);
onCancelListener = (MethodBinding)restoreAttachedState(context, array[++index]);
}
When I debug into the code, the state passed into the code is an array with the wrong length (7 instead of the expected 5). "state[0]" was a string instead of an array, its value being "_id172" which doesn't appear anywhere in the generated HTML (and this control doesn't have an auto-generated ID), so it is hard to find out what this state is actually for. Any ideas?
