Ben Dotte commented on TAP5-1210:
---------------------------------
This is fixed by adding a conditional if (attrs[i]) inside of the purge()
function of tapestry.js like so:
var attrs = element.attributes;
if (attrs) {
var l = attrs.length, i, name;
for (i = 0; i < l; i++) {
if (attrs[i])
{
name = attrs[i].name;
/* Looking for onclick, etc. */
if (typeof element[name] == 'function') {
element[name] = null;
}
}
}
}

> URL: https://issues.apache.org/jira/browse/TAP5-1210
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.2.0
> Reporter: Ben Dotte
>
> A MultiZone update currently fails in Internet Explorer given the below
> template. This works fine in Chrome and Firefox. There appears to be an
> instance where purge() in tapestry.js is looping over elements, hits a null
> element, and blows up trying to access .name on it. Hit the "Click Me" link;
> notice the date does not update.
