[Seaside] self request from renderContentOn

[Patrick Collison]

Hi,

I don't understand why the following doesn't work:

renderContentOn: html
    html heading: (self request: 'Enter a title')

I've got it working a little more circuitously (using an anchor with a
callback to set an instance variable), but I don't understand the
error that I get with the above:

MessageNotUnderstood: UndefinedObject>>isGet

UndefinedObject(Object)>>doesNotUnderstand: #isGet
self	nil
temps
aMessage	isGet

...

Anyone got some pointers?

Cheers,

Patrick
