CakePHP v2模型局部变量

I'm working on moving to CakePHP v2 from v1.3.

In my old 1.3 model I had some local variables which a loadData() function set, and then I could retrieve using a get function.

In v2 I get:

Indirect modification of overloaded property [...] has no effect 

I've searched but it isn't related to the data/request->data changes.

Any ideas on how to set these local variables?

Thanks in advance!

Are you sure you updated any code that you are trying to assign values to the $this->data array to $this->request->data ?

You can no longer assign manually $this->data['newthing']['here'] any more in 2.0

It must be $this->request->data['newthing']['here'] or unset $this->request->data['currentthing']['here'] etc etc

Like the others said, however, some code would be nice if you have the time. Thanks.
