Hi Helma
Variables seem to be restrained to the scope of the Macro (the same for
forEach), we work around this like this, maybe it'll work for you.
declare a global variable(we use a hash but you can use any structure):
<jx:set var="globalvars" value="${java.util.HashMap(5)}"/>
<myMacro someParameter="somevalue"/>
<jx:set var="push" value="${resultvar}"/>
<jx:set var="dummy" value="${globalvars.put('getResult', resultvar)}"/>
</myMacro>
<p>${globalvars.getResult}</p>
