Hi,
I have tried it and it seem to me that this is a issue. It seems to me
that the scroll values are applied on the wrong DOM node.
If you can modified the TextArea class than override the original
methods by adding these methods to it:
getScrollLeft : function()
{
this._visualPropertyCheck();
return this._getTargetNode().children[0].scrollLeft;
},
getScrollTop : function()
{
this._visualPropertyCheck();
return this._getTargetNode().children[0].scrollTop;
},
getScrollWidth : function()
{
this._visualPropertyCheck();
return this._getTargetNode().children[0].scrollWidth;
},
getScrollHeight : function()
{
this._visualPropertyCheck();
return this._getTargetNode().children[0].scrollHeight;
},
setScrollLeft : function(nScrollLeft)
{
this._visualPropertyCheck();
this._getTargetNode().scrollLeft.children[0] = nScrollLeft;
},
setScrollTop : function(nScrollTop)
{
this._visualPropertyCheck();
this._getTargetNode().scrollTop.children[0] = nScrollTop;
},
Hope this solves your issue.
Cheers,
Chris
