Using the select widget actions

[TonyM]

Folks,

Any guidance on why this may not work would be appreciated.

• The below macros uses a select widget to set a selected-input field
• I am then using the actions parameter on the select widget to invoke set-input-actions
• However the intended actions to set the input field never works

\define set-input-actions()

<$list filter="[{!!selected-input}match[allobjects]]">

   <$action-setfield $field="input" $value="[!is[system]object-type{!!selected-object}]"/>

</$list>

<$list filter="[{!!selected-input}match[objects]]">

   <$action-setfield $field="input" $value={{!!instances-list}}/>

</$list>

<$list filter="[{!!selected-input}match[lists]]">

   <$action-setfield $field="input" $value="{{!!selected-lists}}"/>

</$list>

<$list filter="[{!!selected-input}match[filter]]">

   <$action-setfield $field="input" $value="{{!!selected-filter}}"/>

</$list>

\end

\define select-input()

<$select field=selected-input actions=<<set-input-actions>> >

<option value="allobjects">All Instances of Object</option>

<option value="objects">Selected Objects</option>

<option value="lists" >Selected list(s)</option>

<option value="filter" >Input Filter</option>

</$select>

\end

<<select-input>>

I have tested the conditions in the actions but they are not working "as actions"

• Could it be that the actions are called before the selected-input field is set?
• But then the previous value would be used and it is not!

• actions

  A string containing ActionWidgets to be triggered when the key combination is detected

• Later I will need to trigger these actions again with changes other than selected-input as well.

Is there a better, or even working method?

Any help would be appreciated.

Regards

Tony

Is the output of your filters what you want currentTiddler set to? 

If not, use a different variable in the list widget or specify the tiddler for the actions.

When you read the answer, I think you'll go "D'oh!":

The $list widgets in set-input-actions() are changing the value of currentTiddler.  As a result, the $action-setfield is creating new tiddlers named with the matched value!

Adding variable="null" to each $list widget fixes the problem.

Thanks for that. That is a reoccurring blind spot that can be hard given the problem is an absence of something.

I am very gratefulTony
