[Seaside] Help with understanding how #call: works

[Diogenes Moreira]

Hi,

In Simple words..

When you use #call, you send the control to B object and  Object A waits for
B object answer.

I can guess  this problem happend  becouse  B Object don't receive any
canvas or context. renderON: method do this.

If you want render the B Object, the correct Form is:

#renderContentOn: html
      "child is a instance variable"
     self child:=B new.
     html render: self child.


And not forget children method.

#children
       ^ self child.

Is very common use #call method in callbacks..

Regards

PD: sorry for my english.
