Hello All,
I have spent many hours trying to figure out the answer to my problem to no
avail, so I avail myself of your esteemed knowledge.
I am trying to implement the Person Manager in the tutorial. This should be
simple and for the most part it is.
I added the action method below to call the default Person Editor. It gets
called properly but clicking on the Save button does nothing. The halt code
is never reached, i.e. the editor never seems to answer...
PersonManager>>add
| e p |
e := MAPersonEditor new.
p := self call: e.
self halt.
p isNil ifFalse: [ self persons add: p ].
The PersonManager >>renderContentOn: method is implemented as follows:
renderContentOn: html
html heading level: 3; with: 'Person Manager'.
html anchor
callback: [ self add ];
with: 'Add New Person'.
self persons do: [ :p |
html text: p firstName , ' ' , p lastName]
Can anyone tell me what it is that I have failed to implement?
Thanks in advance
John

implement?
As far as I see your code looks ok. How does MAPersonEditor look like?
Is the button surrounded by a form? Does the button do an #answer: at
some point?
Cheers,
Lukas

Hi Lukas,
MAPersonEditor looks OK to me, the buttons are within the form, etc...
Last night, after sending that email, I happened to click on the Save button
without filling in any fields and the validation code was triggered (error
msgs displayed regarding first and last name) so it appears the
MAContainerComponent's save method is getting called. I will start from
there tonight, inserting a break and see where the code goes.
I am not the worlds greatest smalltalker and, while I have been enjoying the
exploration of the Magriitte hierarchy, I am not yet that quick to be able
to say, "oh that must be in the MAXXXXDecoration object" etc. I will let you
know how it goes tonight.
Warm regards
John

After further investigations, it does not appear that anything is amiss.
MAContainerComponent>>save method runs to completion and sends self answer:
self model. As I step into that send it goes through the decorationDo: [
:each | each handleAnswer: anObject ] etc. But none of the objects seem to
handle the answer lol. Can you tell I am a little bit lost?
Then I decided to run the pierexample app from the dispatcher. Clicked on
the Add link, went through the motions to add a new page(?), clicked save
and I hit the breakpoint in MAContainerComponent>>save method htat I had set
above. This is interesting, as I step through it and get to
decorationChainDo: I noticed that the first decoration in the chain is a
WAAnswerHandler, on my PersonManager test app it is a MAValidationDecoration
then a MAFormDecoration, no WAAnswerHandler...could this be it? (I am
attempting now to see who might add the WAAnswerHandler to the Pier form's
decoration chain. heh Wish me luck lol)
Warm regards

I looks like the MAContainerComponent does an answer, but not the
PersonManager? Is the Magritte Form a child of PersonManager? If so,
you need to pass the answer to the outer component. As far as I
understand your code, it looks like a different component answers than
the one that was called.
So in the PersonEditor where you create the Magritte Component do
something like this:
child := person asComponent.
child addValidatedForm.
child onAnswer: [ :m | self answer: m ]
The last line captures the answer of the Magritte component and lets
the PersonEditor pass it on.
HTH,
Lukas

I'll be darned. That works!
I am a little baffled that WAComponent>>call: adds an onAnswer: block but
that is not enough...I guess I have a bit more to learn =)..
Thank you for your help Lukas.
Warm regards

Yes, it adds an answer block, but not to the place where the Magritte
component answers from.
