/*
* We have to implement the setLeft method because if we use the one provided by ZK
* the tasks won't we moved back to its original position when they are dropped on an invalid position (i.e before the end
* of the main task) on a dependency relation
*
* This is the default boddy for a ZK set<AttributeName>
*
* function (v, opts) {
if (before) v = before.apply(this, arguments);
var o = this[nm];
this[nm] = v;
if (after && (o !== v || (opts && opts.force)))
after.apply(this, arguments);
return this;
};
*
* The before and and after properties can be set to something different to the default using the $define property.
*
*
* Our problem happens because if the dependent task is already aligned at the end of the main tasks
* and thats (for example) style. left = 800px, when we move it to an invalid position the server will try to set again
* the left property to 800px but when the default setter works it checks if we are trying to set a value equal to the previous
* one and in that case it doesn't apply the after function.
*
* Setting the force option to true does the trick
