How to show the errors produced when a SUEvaluator is used ?

Hello all.

When I use a SUEvaluator and an error occurs, an the error isn't rendered, whereas with a SUUpdater works properly. How to show the errors produced when a SUEvaluator is used ?

Here is the code to reproduce the problem

renderContentOn: aRenderer

    aRenderer select
        list: #(2 1 4 5 6);
        selected: 1;
        id: 'updaterList';
        callback: [ self error: 'an unexpected error' ]; "Show the error report"
        onChange: (aRenderer updater
                                id: 'show';
                                triggerFormElement: 'updaterList';
                                callback: [ :r | r html: 'hello' ]).

        aRenderer select
            list: #(2 1 4 5 6);
            selected: 1;
            id: 'evaluatorList';
            callback: [ self error: 'an unexpected error' ];
            onChange: (aRenderer evaluator
                                triggerFormElement: 'evaluatorList';
                                callback: [ :r | r element id: 'show';
                                                    update: [ : rr| rr html: 'hello'] ]).

        aRenderer div id: 'show'; with: ''

I'm using Seaside2.8a1-pmm.577 and Scriptaculous-lr.242

Thanks in advance.
Juan M.

I assume you are already using FireBug.

SUEvaluator should open a debugger in your image, but in this case the
form callbacks are not caught (only the primary callback). Can you
file a bug-report on this. SUUpdater normally renders in some way to
the page, but this is not visible in all cases.

It is a difficult problem, because Seaside cannot know what the user
wants to do with the generated output. I guess using something like
FireBug is the only feasible solution. In the log of FireBug you
immediately see any problems.

Cheers,
Lukas

I would like to replace the contents of the tag body with the error report. Something like:

...

[ "proceses callback" ]

on: Error

do: [ : err | aScript element

id: (SUStream on: 'document.body');

update: [: render | self reportError: err on: render ] ]

...

It is possible?

Yes, I use it, but the problem is that I cannot inform users that an error has occurred

Cheers,
Lukas

Sure, that might work in your specific case. I am not sure, if this is
something that makes sense in all applications.

The event #onFailure: or one of the others might help here.

Cheers,
Lukas

Could it be a good default, since the error is at least made visible?
