The issue here is that when you push the button in the modal dialog, you should already know if it will be a full page request or an ajax request. Because you don’t know that yet, you can only perform an ajax request that returns a script to either perform the full page request, or adds the error message to the dialog:
html tbsButton
bePrimary;
onClick:((html jQuery ajax)
serializeForm;
script: [ :s | self showErrorMessage ifTrue: [ s << (self scriptForErrorMessageOn: s) ] ifFalse:[ s << (self scriptOnSuccessOn: s) ] ]);
with: ‘Go!’
The script to show the error message would be a ‘normal’ jquery script that appends some html somewhere (this is application specific).
The script to perform the full page request can be built in Seaside as follows:
scriptOnSuccessOn: canvas
^ canvas javascript callback: [ … do whatever you would do in a Seaside callback … ]
