Hi Jim,
First question is very interesting: parameter tags + ifs are not very
good friends. There must be certainly a better way to do it, but this is
the workaround I usually use in show.dryml:
<%
custom_list = "client, location, ..."
custom_list += ", status" if @record.status == 'draft'
%>
<show-page>
<field-list fields="&custom_list"/>
</show-page>
I think the answer to the second question lies in the context. Try
something like this:
<show-page>
<field-list: fields="...">
<append-status-view:>
<transition-buttons with="&this_parent"/>
</append-status-view:>
</field-list:>
</show-page>
When you are inside the view of "status", the context is the status of
the record, and not the record. The "transition-buttons" tag needs the
record to work.
So in order to do that you can use this magic spell:
with="&this_parent"
this_parent makes you go up the ladder to the parent context. It's
really useful!
Regards,
Ignacio
