Only in Internet Explorer 11

I have a <zk forEach> list of <toolbarbutton onClick="win.doSomething(self)" /> There is also a header above the list with toolbarbuttons.

Two things:

  • if the list is long and you scroll the window down, all hyperlinks give an alert with : For input string : "<some doublevalue>"; if you scroll back sometimes everything works again, but mostly it's definitely broken. A solution is to put the list in a div with it's own scrollbar. It only goes wrong if the body is scrolled. So it is necessary to remove the body scrollbars.

  • If the window's zoom factor is not 100% you get the same error if you click the hyperlink. It is possible to make it 100% using Ctrl-mousewheel and everything works.

I have no clue why this happens in IE11. It seems like all ZK-bindings are broken.

Is it only a 3.6 issue? Or is Microsoft trying to kill a good framework? Upgrade to version 5,6,7 or 8 is not an option for me, can i expect a bugfix for this?

I fixed this: In ZK 3.6.4 the org.zkoss.zk.au.in.MouseCommand uses Integer.parseInt() to parse mouse data[0] and data[1] ie11 return this data as doubles, so the code throws an Exception.

I changed this to Double d = Double.parseDouble(), then get d.intValue()

if loaded in /classes/ this class is used by tomcat, instead of the one in the /lib/zk*jar
