[Zope] Re: Variable name of the ZOPE root? For use in TREE

[Kevin Howe]

Hi, figured it out:


If you try to use PARENTS[-1] directy it doesn't work:

Example:
        <!--#tree "PARENTS[-1]" branches_expr="objectValues()" sort=id-->


but if you put it into a variable and then call the variable, it works:

Example:
        <!--#call "REQUEST.set( 'ZopeRootObject' , PARENTS[-1] )"-->

        <!--#tree ZopeRootObject branches_expr="objectValues()" sort=id-->

Strange.
