Error with given script on mobile

[Shawn Smalley]

I have a startup script provided from you guys in this post:

https://forums.cnxcorp.com/web/forum/valence-community-support/valence-framework-6-x/16501-using-edit-grid-checkbox-row-selection-to-change-appvar

The script lets me check and uncheck a row in a grid to change an app variable. That app variable is tied to enabling and disabling buttons on a separate widget so that the user can only click the buttons if a row is checked in the grid.

It seems that the script is only partially working on mobile: once a row is check, the buttons do enable, which is good, but after unchecking the box the buttons stay enabled, and I can't seem to find a way to make them disable.

Is there any changes to the script I could make so that it works on mobile? it seems to be working fine on desktop. Alternatively I know you guys mentioned in the previous forum post that you would add it as a feature request, so is there possibly a cleaner way of doing it at this point?

Thanks

Updated script:

var testAppVar     = getAppVar('testAppVar'),
    editGridWidget = getWidget('myEditGrid');

editGridWidget.down('grid').on('selectionchange', function (sm, selected) {
    const sel = sm.getSelected();
    
    if (sel.length > 0) {
        setAppVar('testAppVar', true);
    } else {
        setAppVar('testAppVar', false);
    }
});

success();
