Problem with List with dynamic field in model

[neoraptor]

Hello,

I have a list that is linked with a store. This store is linked with a model.

I added fields and validation dynamically with :
for (var i = newFields.length - 1; i >= 0; i--){
MyApp.model.patientModel.prototype.fields.add(new Ext.data.Field(newFields[i]));
}

This works fine wenn I insert data (validations works and fields are added to the D.


The problem, is that my list does not display this dynamic fields (through itemTpl). The static fields in model are displayed correctly.
Wenn I insert a new element, the dynamic fields are displayed in the list for this element.

How could I update the list so that the dynamic fields are included?


​Any help is welcome

You really should have your model setup with the fields you want at instantiation

Is it not possible to update the model before displaying the list?
I need to have a dynamic model for my application.
