[html-formfu] Client side validation in ExtJS

[Mario Minati]

Hello Moritz,

do you have any means about client side validation in ExtJS?

ExtJS 2.2.1 doesn't provide a good way of defining a custom validation method. 
The only way I see is to overwrite the validateValue method which all form 
field inherit from Ext.form.Field, but they provide allready specific 
functionallity.

An approach would be to overWrite validateValue with a function that calls our 
FormFu constraints and filters and after they are passed invokes the original 
validateValue code.

As I like the lazy instantiation I was looking for a way to do this poking 
aroundwith function pointers.
What I came over is the config option plugins which accepts a plugin object(!) 
not name.

What do you think?
Shall we create such a plugin which injects the necessary code to check forms.


Greets,

Mario Minati
