Sheetworker on-change events not firing when changes are made within a routine called by sheet:opened event

Re-opening this thread from a year ago as I just encountered it today.&nbsp; I initialize a few attributes when opening a sheet through the sheet:opened event.&nbsp; On:change listeners on skill fields connected to those attributes work just fine when the attributes are changed through user interaction.&nbsp; However, the change made to the attribute by the function in the sheet:opened event does not fire the on:change event, and so does not update the connected skills. <a href="https://app.roll20.net/forum/post/7266026/sheetworker-on-change-events-not-firing-when-changes-are-made-within-a-routine-called-by-sheet-opened-event/?pageforid=7268028#post-7268028" rel="nofollow">https://app.roll20.net/forum/post/7266026/sheetworker-on-change-events-not-firing-when-changes-are-made-within-a-routine-called-by-sheet-opened-event/?pageforid=7268028#post-7268028</a> &nbsp;&nbsp;&nbsp;&nbsp; //&nbsp;Stats&nbsp;to&nbsp;initialize&nbsp;with&nbsp;a&nbsp;value&nbsp;of&nbsp;1 &nbsp;&nbsp;&nbsp;&nbsp; const &nbsp; statListOne &nbsp;=&nbsp;[ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ' brawn ' , &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ' agility ' , &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ' intellect ' , &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ' cunning ' , &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ' willpower ' , &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ' presence ' &nbsp;&nbsp;&nbsp;&nbsp;]; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; statListOne . forEach ((stat)&nbsp; =&gt; &nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; on ( ' sheet:opened ' ,&nbsp;()&nbsp; =&gt; &nbsp;{&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; getAttrs ([ stat ],&nbsp;(values)&nbsp; =&gt; &nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; const &nbsp; thisStat &nbsp;=&nbsp;( isNaN ( values [ stat ])&nbsp;||&nbsp;( values [ stat ])&nbsp;===&nbsp; 0 &nbsp;&nbsp;||&nbsp;( values [ stat ])&nbsp;===&nbsp; " 0 " )&nbsp;?&nbsp; 1 &nbsp;:&nbsp; parseInt ( values [ stat ]); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; const &nbsp; statValue &nbsp;=&nbsp; thisStat &nbsp;&gt;&nbsp; 0 &nbsp;?&nbsp; thisStat &nbsp;:&nbsp; 1 ; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; setAttrs ({[ stat ]: statValue });&nbsp;&nbsp; //&nbsp;Properly&nbsp;sets&nbsp;the&nbsp;stats,&nbsp;but does&nbsp;not&nbsp;fire&nbsp;an on:change&nbsp;event;&nbsp;bug&nbsp;reported &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}); &nbsp;&nbsp;&nbsp;&nbsp;}); &nbsp; const &nbsp; skillStat &nbsp;=&nbsp;{A BUNCH OF skill:stat PAIRS} &nbsp;&nbsp; for &nbsp;( const &nbsp; skill &nbsp;in&nbsp; skillStat )&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp; on ( ' change:brawn&nbsp;change:agility&nbsp;change:intellect&nbsp;change:cunning&nbsp;change:willpower&nbsp;change:presence ' ,&nbsp;(eventInfo)&nbsp; =&gt; &nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; const &nbsp; stat &nbsp;=&nbsp; eventInfo .sourceAttribute; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if &nbsp;( skillStat [ skill ]&nbsp;===&nbsp; stat )&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CalculateDiceStatChange ( eventInfo , skill , stat );&nbsp;&nbsp; //&nbsp;Goes&nbsp;on&nbsp;to&nbsp;do&nbsp;the&nbsp;calcs&nbsp;on&nbsp;a&nbsp;manual&nbsp;change,&nbsp;but&nbsp;not&nbsp;from&nbsp;the&nbsp;sheet:opened&nbsp;event &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;&nbsp;});&nbsp;&nbsp; &nbsp;&nbsp;};

Someone with more skill points in Javascript than me will be along soon, and I could be wrong, but I do not think you can have your on() command inside a for . The sheetworkers respond to events so the on() needs to happen first to run anything.

Thanks Rabulias.&nbsp; In this case that doesn't seem to be the problem.&nbsp; I use this same pattern in several of my sheet workers and it seems to work fine.&nbsp; And the Universal Sheet Worker examples have a bunch of on:change events inside of for loops. <a href="https://wiki.roll20.net/UniversalSheetWorkers" rel="nofollow">https://wiki.roll20.net/UniversalSheetWorkers</a> The first function works and properly sets the stats.&nbsp; The second function works and sets the associated skill value when a user directly interacts with one of the stat fields by typing in or using the browser's number arrows (they're all number fields)--that definitely triggers an on:change event.&nbsp; It's that the setAttrs() inside the first function that is originally triggered with a sheet:opened event doesn't trigger a change event, which is what the second function detects in order to run.&nbsp; Everywhere else when setAttrs() is called, a change event happens on the fields changed.&nbsp; Mine is just one example, but it happens with any setAttrs() inside a sheet:opened event.&nbsp; Seems like an oversight on the Roll20 end that can be corrected.

Here is a very basic example that anyone can enter into a custom sheet sandbox: &lt; input &nbsp; type =" number "&nbsp; name =" attr_stat "&nbsp; value =" 0 "&nbsp;/&gt; &lt; script &nbsp; type =" text/worker "&gt; &nbsp;&nbsp;on('sheet:opened',&nbsp;()&nbsp;=&gt;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;setAttrs({'stat':&nbsp;1}) &nbsp;&nbsp;&nbsp;&nbsp;}); &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;on('change:stat',&nbsp;(eventInfo)&nbsp;=&gt;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;console.log(eventInfo); &nbsp;&nbsp;&nbsp;&nbsp;}); &lt;/ script &gt; When you open the sheet, you can see the stat is properly set to 1 (from a default value of zero, or whatever was entered before).&nbsp; When you change the number field, you can see the console message with the eventInfo.&nbsp; However, that console doesn't appear when the sheet is opened and the value is changed to1 via the setAttrs inside the sheet:opened event -- it doesn't seem to fire a change event.

I haven't confirmed this, but I suspect that the sheet:opened event is global in scope, so it doesn't know what character sheet to update when calling a setAttrs.&nbsp; Has anyone else had this issue with sheet:opened?
