The following setup:
textfield.addListener("changeValue", this._onChangeValue, this);
_onChangeValue : function(e)
{
var value = e.getData();
if(value > 0)
{
...
}
else
{
textfield.setValue(e.getOldData());
}
}
The problem is it creates recursion. Look at the value changing in the
textfield:
original: 3 -> normal in the function
type in: 0 -> function sets the textfield to the oldData 3, but the new oldData
becomes 0!!!!
type in: -1 ->function sets the textfield to the oldData 0 and the infinite
recursion started.
In this case there must be some way to not change the erroneous value to the
oldData like it works here.
If I call a throw new Error("Error!"); then the oldData is NEVER set to the
erroneous value!!! ...and it works!
I tried stop() which does not work and I can not see any other way except a
dirty clotty way: having a variable this.__data to buffer.........but it is an
unacceptable way.
Any other solution?
