I apologise to the group because I emailed Eric directly instead of going
via the group. I attach the details of the conversation below for anyone
who is interested in using this very useful macro.
*My initial query:*
I am trying to use your edit-list macro. I can get the pop-up list to
display but when I select an item, its value is not stored in the field
I specified.
<$macrocall $name="edit-list"
field="exhibition_id"
filter="[tag[Exhibitions]!tag[Index]]" />
No matter what I do, the field, exhibition_id remains blank but the
pop-up goes blank a well after making the selection. The field is
defined on the tiddler showing the pop-up.
Also, is there a way to display field data in the pop-up rather than
just the title?
*Eric's first reply:*
Although the documentation says that the tiddler param will default to the
currrent tiddler, this is not actually working at present.
Until I can fix this, you can bypass the problem by explicitly including
"tiddler=<<currentTiddler>>" as a param.
Also, if you want to display AND return a field value instead of a title,
then you can just add "get[fieldname]" to the filter param, where
"fieldname" is the field you wish to display and return. Thus:
<$macrocall $name="edit-list"
tiddler=<<currentTiddler>> field="exhibition_id"
filter="[tag[Exhibitions]!tag[Index]get[fieldname]]" />
However, if you want to display field values instead of titles, BUT still
return the corresponding title as the selected value, use the "listview"
param, like this:
<$macrocall $name="edit-list" tiddler=<<currentTiddler>>
field="exhibition_id"
listview="{{{ [<value>get[fieldname]] }}}"
filter="[tag[Exhibitions]!tag[Index]]" />
Note that the documentation for the edit-list macro currently not
finished. I started to write it a while ago, but got sidetracked with
other projects. Perhaps I can get around to completing it after I fix the
problem with the default value for the tiddler param.
*Eric's subsequent followup reply:*
I've just uploaded a fix for the tiddler param default to
<<currentTiddler>>. You can get a copy of the updated
TiddlyTools/Macros/edit-list from
http://tiddlytools.com/filtergenerators.html#TiddlyTools%2FMacros%2Fedit-list
With this fix, you can now omit the "tiddler=<<currentTiddler>>" param and
just write:
<$macrocall $name="edit-list"
field="exhibition_id"filter="[tag[Exhibitions]!tag[Index]]" />
One important note: when the "target" tiddler for the input field is the
<<currentTiddler>>, typing into the text input causes the input to lose
focus as each character is typed.
This is a known issue in the TWCore, and since my <<edit-list>> macro uses
the TWCore <$edit-text> widget, it behaves the same way.
This caused by the way that the TWCore's "refresh" handler works: whenever
the value of a field in a tiddler is changed, the display of that tiddler
is automatically refreshed to reflect the updated value. Thus, when the
$edit-text widget (or the <<edit-list>> macro) is displayed in the same
tiddler as the field that is being changed, it is also re-rendered, causing
it to lose focus.
There are some work-arounds that are discussed here:
