Conditional View: transclusion/view and caption field is empty or has wikitext

[Mohammad]

Consider a $list like below lists tiddlers tagged with xx with their caption, if not present with their title

<$list filter="[tag[xx]]" >

<li>
<$link to=<<currentTiddler>> tooltip=<<currentTiddler>>>

<$transclude field=caption>

   <$view field=title/>

</$transclude>
</$link>
</li>

</$list>

Assume we have two tiddlers tagged with xx as below:

tidA has an empty caption filed

title: tidA
tag: xx
caption:      


title: tidB
tag: xx
caption: {{myTiddler}}


title: tidC
tag: xx

where myTiddler has no text filed.

Except for tiddler tidC, other cases shows empty or no value!

What do you think? What solution do you propose?

b + c worked OK for me. I think you'll need the reveal widget:

<$list filter="[tag[xx]]" >
<li>
<$link to=<<currentTiddler>> tooltip=<<currentTiddler>

>>
<$reveal stateTitle=<<currentTiddler>> stateField=caption type="nomatch" text="">
<$transclude field="caption"/>
 </$reveal>
<$reveal stateTitle=<<currentTiddler>> stateField=caption type="match" text="">
<$view field="title"/>
 </$reveal>

</$link>
</li>
</$list>

Thanks Mark,

 but tidB does not work.

Its caption field is {{myTiddler}}

There is myTiddler with empty text field.

Sure you populated "myTiddler" ? Works for me ...

[Mohammad]

So, what does it show: the title: tidB?

[Mark S.]

Does my screenshot not show up in your mail?

tidB shows the content of the tiddler, mytiddler, which is referenced by {{myTiddler}} in the caption field of tidB.

See attached json.

No!

Thank you! I got it. It works if myTiddler text field is populated! In my original post myTiddler text field is empty! That is I could not reproduce your results.

When I populate myTiddler text field then it works as you posted.

Many thanks Mark!
