David,
The list widget by default changes the currentTiddler value for each title
it generates.
In you code you are trying to look at the fields in each of the tiddlers
the filter finds.
<$list filter="[tag[Task]!tag[Done]]" *variable=currentTiddler*>
<$reveal type="match" state="!!edit_priorities" text="1">
<$edit-text field="priority" size="3" />
</$reveal>
<nobr> <$checkbox tag="Done"/> <$link>{{!!title}}</$link></nobr>
<br/>
</$list>
In bold is what the default is without giving it.
Now if you do not need to use the lists titles inside the list widget use
another variable
*variable=nul* is what I use if the code does not use the title, however if
it did it could use
<<nul>>
A Quick look at your code suggests it is all you need to make it wok
<$list filter="[tag[Task]!tag[Done]]" *variable=nul*>
<$reveal type="match" state="!!edit_priorities" text="1">
<$edit-text field="priority" size="3" />
</$reveal>
<nobr> <$checkbox tag="Done"/> <$link>{{!!title}}</$link></nobr>
<br/>
</$list>
Basically it is a simple convention If I don't use the variable in the list
statement I call it nul, or If I do use the list result I chose a
meaningful name lets say list-item
Most widgets then let you specify
tiddler=<<list-item>>
or in another parameter
By using the variable= the shorthand ways such as
{{!!fieldname}}
Continue to work.
Did you know if you allow the currentTiddler to change while listing a
number of tiddlers there are other short cuts
{{||$:/core/ui/Buttons/edit}} will give you an edit button for the current
tiddler.
Regards
TW Tones
