Hi
I have a similar problem. I am trying to achieve something like this
(although the code doesn't work):
/define getList(tag) <$list filter="[tag[$tag$]]"/>
<$button set="!!myfield" setTo=<<getList {{!!myotherfield}}>> />
How do I force the evaluation of the macro before the set operation? (I
keep getting "{{!!myotherfield}}" as output.)
regards
