greetings!

i have the following code which is working properly except for the part which should open modal panel

<rich:panel>
 <f:facet name="header">
 <h:outputText value="#{messages['ManageClassifications']}" />
 </f:facet>
 <rich:modalPanel id="mpClassification" minHeight="300"
 minWidth="650" zindex="2000" autosized="true">
 <f:facet name="header">
 <h:outputText value="#{messages['NewClassification']}" />
 </f:facet>
 <f:facet name="controls">
 <h:graphicImage value="img/16x16/actions/cancel.png"
 style="cursor:pointer"
 onclick="Richfaces.hideModalPanel('mpClassification')" />
 </f:facet>
 </rich:modalPanel>
 <rich:contextMenu attached="false" id="menu">
 <rich:menuItem action="#{classificationLinker.createNode}"
 onselect="javascript:Richfaces.showModalPanel('mpClassification',{width:650, top:200})">
 <f:param value="{clasid}" name="siblingId" />
 <b>option1</b>
 </rich:menuItem>
 <rich:menuItem action="#{classificationLinker.createNode}"
 onclick="javascript:Richfaces.showModalPanel('mpClassification',{width:650, top:200})">
 <f:param value="{clasid}" name="siblingId" />
 <b>option2</b>
 </rich:menuItem>
 <rich:menuItem action="#{classificationLinker.createLeaf}">
 <f:param value="{clasid}" name="parentId" />
 <b>option3</b>
 <rich:componentControl disableDefault="true" event="onselect"
 for="mpClassification" operation="show" />
 </rich:menuItem>
 <rich:menuItem action="#{classificationLinker.createLeaf}">
 <f:param value="{clasid}" name="parentId" />
 <b>option4</b>
 <rich:componentControl disableDefault="true" event="onclick"
 for="mpClassification" operation="show" />
 </rich:menuItem>
 </rich:contextMenu>
 <rich:tree id="treeClassification" switchType="ajax"
 icon="img/CasePics/book_yellow.png"
 iconLeaf="img/CasePics/book_yellow.png" preserveModel="true">
 <rich:recursiveTreeNodesAdaptor included="true"
 roots="#{caseService.classificationRootNodes}"
 nodes="#{classification.childClassifications}"
 var="classification">
 <rich:treeNode>#{classification.name}
 <rich:componentControl event="oncontextmenu" for="menu"
 operation="show">
 <f:param value="#{classification.id}" name="clasid" />
 </rich:componentControl>
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
 </rich:tree>
 </rich:panel>

essentially, user should be shown a tree and then on right-click get a context menu, select an option which should first trigger an action and then show modal panel. i put four options to illustrate the behavior:

option1 - shows modal panel for less than a second, then triggers the action and closes modal panel
option2 - triggers action only
option3 - does nothing!
option4 - triggers action only

and my second question is: how do i trigger action first and then show modal panel, in other words i'd like to achieve same behavior as with pageflow "trigger action, and then from action redirect etc."

thanks a lot
