Hi, I'm still trying to implement the AMChart component (or whatever),
and I managed to get down to the point when a URL is dynamically
generated, requested, and my block is executed. Now, my problem is that
this request does not generate any response, and rather generates a 302
Found with a Location... kind of redirect to the page containing the
The code I need should look like:
and I need the URL to return something dynamically generated from the
block, in the example below it's the string 'some string I want returned'.
My current try looks like:
| encoder |
^ String streamContents: [:strm |
strm nextPutAll: 'someJSFunction('.
encoder := WAURLEncoder on: strm.
encoder nextPutAll: (html context actionUrl
addParameter: (html callbacks registerCallback: [
'some string I want returned'])) asString.
strm nextPutAll: ');'.
I also tried with registerActionCallback: and pretty much all the family.
Also tried with self answer: 'some string...', and other combinations...
Any help? what's wrong with this, and more important, how's is it right?
and then... I think this could make it into a useful tutorial. I may
be the first outside the core team to write a complex Component (I doubt
it), but I'm surely not the last to do it.
