This one is getting me as well on Riot 3.0.4 - just switched to riot 3.0 and started updating everything, then jumped to 3.0.4 to hopefully help fix the bugs I got from going to 2 to 3 and now more bugs with this issue...


@riot/collaborators the current yield behavior should be fixed I would like to put it on the top of our priority list together with performance improvements. Thanks @juodumas for reporting this issue


On line 1135 in riotjs I did this:

// the value for the toggle must consider also the parent tag
//   value = isToggle ? tmpl(expr.expr, extend({}, this, this.parent)) : tmpl(expr.expr, this),
  value = tmpl(expr.expr, this),

I believe someone put this in to fix an issue, but I am not having that issue that I can find, and this fixed the issue here. Hope this helps solve the problem for the next release.

@TimWillis I did same as you, this issue has been vexing me last few days


Here's the original commit 9e024dd#diff-d54b456d54b337c5989fdf67462089ae

@GianlucaGuarini what was the reason here for the show directive also evaluating the parent? Seems to cause some complications, removing this would also eliminate the need for my PR patch #2186
