enable edit button for admin user

Hi,
     This is ramesh. I am implementing orbeon xform in my application. I have to do enable edit button for admin user only. if normal user login i have to disable the edit button.

      I have seen in examples as if relevant attribute is false then button will be in disable mode.
but it is not working for me.


          <xf:instance  id="term">
               <data xmlns="">
                <info>
                   <admin-name>false</admin-name>
                  </info>
                 </data>
              </xf:instance> 
    <xf:bind id="one" nodeset="/data/info/admin-name" relevant="instance('term')/info/admin-name"/>

      <xf:trigger bind="one">
          <xf:label>edit</xf:label>
        </xf:trigger >


can any one please give me suggestion how can i do it



Thanks & Regards

Hi Ramesh,

Your problem can be solved as
1) <xf:group ref=".[instance('term')/info/admin-name]">
            <xf:trigger >
          <xf:label>edit</xf:label>
        </xf:trigger >
          </xf:group>
or
2) you can keep another tag <isadmint>true</isadmin>  or false to that node and try with bind or <xf:group ref=".[instance('term')/info/isadmin ='true']">
            <xf:trigger >
          <xf:label>edit</xf:label>
        </xf:trigger >
 </xf:group>

Thanks for your replay.
             I got it with second option

Thanks

Hi Ramesh,

Just a couple of things.  If the relevant attribute is false then the button will not show at all - if you want the button visible but disabled then what you need is to set the readonly attribute to true.  What is really giving you a problem, though, is that the relevant attribute in the bind is not treating the string value "false" as a boolean false.  Basically, as long as there is a node at the location the path points to, then the value is interpreted as a boolean true.  There are various things you can do to fix that, some of which don't work quite as well as you might hope.  In the end the one I would probably use is

<xf:bind id="one" nodeset="instance('term')/info/admin-name" relevant=". = 'true'"/>

An alternative to try would be add a type="xs:boolean" attribute in the bind, or to cast the value to a boolean.  Another option is to not bother with a bind and relevance, but just add a ref attribute to the trigger itself which points to a non-existant location when you want the button to be hidden ... something like

      <xf:trigger ref="instance('term')/info/admin-name[. = 'true']">
	  <xf:label>edit</xf:label>
	</xf:trigger >

Hope this helps.
