Event handler execution count for a handler defined for a behavior is shared among all installations of that behavior

[esbengc]

If a behavior defines an event handler with a dispath count filter, then that filter will track the total number of dispatches across all installations of that behavior, rather than applying to each installation separately.

Example:

<script type="text/hyperscript">
behavior CounterToThree
  on click 1 to 3 increment my textContent
</script>
<button _="install CounterToThree">0</button>
<button _="install CounterToThree">0</button>

Expected behavior: I expect to be able to click each button 3 times after which the two two buttons should display 3 3

Actual behavior: The 2 buttons can be clicked 3 times in total. That is, once they display either 3 0, 2 1, 1 2 or 0 3, neither button will respond to additional clicks.

To be honest I don't understand why your code didn't works.. but I made a change on it and now works fine:

<script type="text/hyperscript"> behavior CounterToThree on click increment my textContent unless my textContent is 3 </script> <button _="install CounterToThree">0</button> <button _="install CounterToThree">0</button>
