Hi Matabele
Than you very much :-P
I tried to create first half of a combi button which should create a
teacher and/or a task which didn't already exist - I didn't succeed ... -
have to try again when I get some more toime on my hands ..
This was my first (half) attempt:
<$reveal type="nomatch" state="!!state1" text="show">
<$mangletags tiddler={{temp!!task}} add={{temp!!teacher}}>
<$setfield message="tw-mangle-tags">
<$mangletags tiddler={{temp!!teacher}} add={{temp!!task}}
message="tw-set-field">
<$maketid title={{temp!!teacher}} tags={{temp!!task}}
message="tw-mangle-tags" edit="show">
<$iftid tiddler={{temp!!teacher}} then="tw-set-field" else="tw-new-tiddler">
<$maketid title={{temp!!task}} tags={{temp!!teacher}}
message="tw-mangle-tags" edit="show">
<$iftid tiddler={{temp!!task}} then="tw-set-field" else="tw-new-tiddler">
<$button set="!!state1" setTo="show" message="tw-if-tiddler"
param={{temp!!teacher}}>Assign/Create/Assign</$button>
</$iftid>
</$maketid>
</$iftid>
</$maketid>
</$mangletags>
</$setfield>
</$mangletags>
</$reveal>
Second half of the button should start here ...
Cheers Måns Mårtensson
