[oni_ffm]

hi
What i want to do is something likes

<rich:panelMenuGroup label="Group 1">
 <a4j:support event="onclick" action="#{panelMenuState.onClick}" >
 <f:param name="clickedItem" value="Group1"/>
 </a4j:support>
</rich:panelMenuGroup>

and

<rich:panelMenuItem label="Item 2.1"
 action="#{panelMenu.updateCurrent}">
 <f:param name="current" value="Item 2.1" />
</rich:panelMenuItem>

but i want to write this in java code. I have problem that i don't know how i can pass parameter ( <f:param name="clickedItem" value="Group1"/> or <f:param name="current" value="Item 2.1" />)

what i have done

HtmlAjaxSupport ajaxSupport = new HtmlAjaxSupport();
ajaxSupport.setActionExpression(FacesContext.getCurrentInstance()
 .getApplication().getExpressionFactory()
 .createMethodExpression(
FacesContext.getCurrentInstance().getELContext(),"#{navigationMenu.onClick}", String.class, new Class[] {}));
ajaxSupport.setEvent("onclick");
ajaxSupport.setReRender("output");
menuGroup1.getFacets().put("a4jsupport", ajaxSupport);

can someone help me, i have not found in "richfaces users guide"
thanks in advance

Hello,

Use javax.faces.component.UIParameter class.

[oni_ffm]

hello,
do you mean

UIParameter parameter = new UIParameter();
parameter.setName("onclickNode");
parameter.setValue("menuGroup1");
ajaxSupport.getChildren().add(parameter);

thanks it works fine

<rich:panelMenuItem label="Item 2.1"
 action="#{panelMenu.updateCurrent}">
 <f:param name="current" value="Item 2.1" />
</rich:panelMenuItem>

By the way, what is <f:param name="current" value="Item 2.1" /> good for?

Where can I find documentation about this feature?

talking about client-server interaction functionality menuItem is fully similar to commandButton . So f:param put to request map in this case as it performed for any command components and could be used in action.
