contextMenu menuItem value to bean

[nimo22]

I view a contextMenu via rich:componentControl triggered by "onRowClick".

<h:form  id="formTable">

<rich:extendedDataTable  value="#{myBean.users}" var="u" height="100px">

<rich:column>

  ..

</rich:column>

..

<rich:componentControl event="onRowClick" for="formMenu:contextMenu" operation="show">
                <f:param name="selectedName" value="#{u.username}" />
</rich:componentControl>

</rich:extendedDataTable>

</h:form>

<h:form  id="formMenu">

<rich:contextMenu  attached="false" id="contextMenu"  submitMode="ajax" hideDelay="0"  showDelay="0">

<!-- using selectedName in a4j:actionparam works   -->   

<rich:menuItem value="Details:  {selectedName}"  reRender="viewUser" limitToList="true"  ajaxSingle="true">

            <a4j:actionparam name="assingValue" assignTo="#{selectedUser.username}" value="{selectedName}"/>

</rich:menuItem>

<!-- using selectedName in a action as a parameter does NOT work , selectedName is always NULL  -->

<rich:menuItem value="Details:  {selectedName}"   action="#{myBean.viewUser(selectedName)}" reRender="viewUser" limitToList="true"  ajaxSingle="true"/>
..

</rich:contextMenu>

</h:form>

Why can I not use the param "selectedName" in "myBean.viewUser(selectedName)" ?

Hi Nimo,

Probably it works. You should enclose all parameters into braces: {...}, but you didn't do this for 'selectedName'.

Hello,

unfortunately this

<rich:menuItem value="Details: {selectedName}" action="#{myBean.viewUser({selectedName})}" limitToList="true" ajaxSingle="true"/>

leads to the following error:

Caused by: org.jboss.el.parser.ParseException: Encountered "{" at line 1, column 38.

I have also tried it by using ui:param instead of f:param.

I have to use f:param to access the attribute via {selectedName} and cannot access it via #{selectedName}.

So, I guess, the only solution is to provide a actionparam.
