OK Brains Trust, this needs all of your input! I can't explain this at all.
Have implemented Joshua's suggestion from above, macro cal and
action-listops code, and added a couple of action-log calls to try and
tract processing.
Code is as follows:
<code>
\define buttonActions()
<$list filter="[tag[Mark]]">
<!--add global exhibition_id to the exhibition_id list-field of each
marked artwork tiddler-->
<!--$listops $subfilter will append any new filter run to the existing
list-field-->
<$action-listops
$field="exhibition_id"
$subfilter="[{$:/TLS/exhibition_id}]"
/>
<$action-log message="artwork_id" value={{!!artwork_id}} />
<!--append each artwork_id to artwork_id list-field of the exhibition
tiddler-->
<$action-listops
$tiddler= {{{ [{$:/TLS/exhibition_id}] }}}
$field="artwork_id"
$subfilter="[{$:/TLS/artwork_id}]"
/>
<$action-log message="exhibition_id" value={{$:/TLS/artwork_id}} />
</$list>
\end
This action will link the marked artworks with the selected exhibition.
The list of marked artworks
<$list
filter="[tag[Artworks]tag[Mark]!<currentTiddler>sort[title]]">
•
<$link/>
<$view field="artwork_title" />
<$view field="artwork_type"/>
<br/>
</$list>
<!-- the selected exhibition id will be stored in the exhibiton_id field on
this tiddler-->
Choose the exhibition from this list:
<$macrocall
$name="edit-list"
tiddler="$:/TLS/exhibition_id"
listview="{{{ [<value>get[exhibition_name]] }}}"
filter="[tag[Exhibitions]!tag[Index]]"
/>
<$action-log message="macrocall exhibition_id" value={{$:/TLS/artwork_id}}
/>
<$button actions=<<buttonActions>> >
Link Artworks to Exhibition
</$button>
