Porting a fix from smartClient

[ispasov]

Hi Isomorphic,

There is an already fixed issue in smartclient 9-10, which was recently discussed in this thread: http://forums.smartclient.com/showthread.php?t=29340

[Long story short, there is code that wraps a IE bug, but it uses a deprecated API (IE11 does not support document.selection) and it raises an exception.]

.. but there is no information for SmartGWT 3.1p branch?
I am trying with the build from 10.Aug.2014 (yesterday) and I see the wrong verification there.

ISC_Forms.js, Line 853:

 
isc.A.$100a=function isc_FormItem__IESelectionStuck(){
  if(!isc.Browser.isIE)return false;
  try{
    var _1=document.selection?document.selection.typeDetail:null
  }catch(e){
    this.logDebug("Internet explorer native 'stuck focus' state detected");
    return true
  }
}

Then this call on Line 911 fails:

if(this.$100a()){document.selection.clear();....}

The exception is caught and then re-thrown from ISC_Core.js ...

We would be grateful if you include the patch in a 3.1p version; This breaks a critical workflow in our system, and if you say that there is not going to be an official patch, we'd have to wrap it the ugly way.
