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]]"
/>
<$log message="macrocall exhibition_id" value={{$:/TLS/artwork_id}} />
<$button actions=<<buttonActions>> >
Link Artworks to Exhibition
</$button>
In a rush but hope this helps. You were assigning the same value for
artwork id over and over from a tiddler, instead of getting it from the
field of the current tiddler in the list loop.
