Can't set proxy *Param properties to undefined

[codemonkey7492]

REQUIRED INFORMATION
Architect Build tested:

Build: 640
Project Type:

ExtJS 4.x
Description:

Can't set proxy *Param properties to undefined (limitParam, pageParam, startParam, etc)
The documentation states if we want to send these params we need to set the value to undefined. SA 2 does not allow this.
Steps to reproduce the problem:

Create a model witha proxy. Try to set the limitParam = undefined.
The result that was expected:


limitParam: undefined
limit param is not sent with request
The result that occurs instead:


limitParam: 'undefined'
limit param is now named 'undefined' and sent with the request
