Subject RE: XSP bug: can get generate() to skip elements using java 'if's
Date Tue, 10 Sep 2002 16:08:56 GMT
Per-Olof,

Ah. You put the closing </xsp:logic before the <xsp:attribute>.

So the full snippet should be:

 <xsp:page>
     <page>
     <xsp:logic>
        if (!request.isUserInRole("root"))
        {
     </xsp:logic> <!-- Note this -->

       <xsp:attribute name="security-error">Not authorized</xsp:attribute>

     <xsp:logic>
     }
     else
     {
     </xsp:logic>
        <content>
         ...
        </content>
     <xsp:logic>
     }
     </xsp:logic>
     </page>
</xsp:page>

Ugh. Will try.
