Now i use Recaptcha and it work well.
But
i,m interesting to use it as Magritte component ( only for simply use
with other MADescription ) and i have do:
1) I copy the
RSRecaptchaComponent to MARSRecaptchaComponent ( as subclass
of
MAElementComponent ).
2) I create MARSRecaptchaComponentDescription
with:
defaultComponentClass ->
MARSRecaptchaComponent
kind ->
RSRecaptcha
3) Now when rendering a component with a description based on
MARSRecaptchaComponentDescription
:
task call: (
collectionOfDescription asComponentOn: model
)
adValidateForm;
addMessage:
'testo';
yourself.
The rendering work well ( i see
MARSRecaptchaComponent right )
But when test the
hasValidateResponse with :
validateSpecific:
anObject
super validateSpecific:
anObject.
anObject hasValidateResponse ifTrue:[ ] .
the requestBody ( RSRecaptcha method ) go in
error:
The anRSRecaptcha parameters
dictionary have :
'challenge'
->nil
'response' ->
nil.
I think registerCallbacksOn: html d'ont work well.
Thank for
any consideration.
Dario
