a4j:support issue

[alexanderbelov]

I use the following:

<h:commandButton value="#{app.nextWindowLabel}"
 binding="#{editMediateActorBean.submitButtonComponent}"
 id="saveButtonMediateActor">
 <a4j:support event="onclick" limitToList="true" action="#{editMediateActorBean.typeNext}"
 reRender="#{editMediateActorBean.innerPanelUpdate}" rendered="#{editMediateActorSessionBean.actionType!='DELETE_ACTION'}"/>
 <a4j:support event="onclick" limitToList="true" action="#{editMediateActorBean.typeFinish}"
 reRender="#{editMediateActorBean.addElementInputFormMessagesUpdate}" rendered="#{editMediateActorSessionBean.actionType=='DELETE_ACTION'}"
 data="#{editMediateActorBean.closePanelAfterSave}"
 oncomplete="if(data){Richfaces.hideModalPanel('#{editMediateActorBean.addElementModalPanelComponentClientId}');}"/>
 </h:commandButton>

And have an exception: java.lang.IllegalArgumentException: Component includeStartPage:include:editMediateActor:j_id46:saveButtonMediateActor not instance of org.ajax4jsf.component.UIAjaxCommandButton
at org.ajax4jsf.renderkit.RendererBase.encodeBegin(RendererBase.java:94)

at com.sun.faces.renderkit.html_basic.GroupRenderer.encodeChildren(GroupRenderer.java:106)
at javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:825)

Please, can anybody tell me what do I wrong?
I use JSF 1.2_06 RI, RichFaces 3.1.3-snapshot.

Please, tell me, why a4j:support does't work this way.

At first you shouldn't use support nested to h:command* - this will cause two submits in one time ajax and common..
