Problems with onChangePostAndUpdate

Hi,

I have a component with two WebDateInputFields. When selecting either
date I want to update the whole component. If I do:

e registerId.
endDateInput := WebDateInputField new aspect: #tst for: observee.
endDateInput onChangePostAndUpdate: e.

it works once and then doesn't react on clicking on the calendars any
more.

If I do:

endDateInput onChangePostAndUpdate: e id.

I get a debugger.

If I move the e registerID and onChangePostAndUpdate: e id. just
before the end of the method like in ...V2.st I don't get the
debugger.

Firebug shows, that after the first date selection e retains its ID
but the ajax.updater tries to update a different ID now.

What's my problem here?

Thanks,

Hi Herbert,

I would start inspecting this problem by extending the existing calendar
demo in Aida (WebDemoApp>>viewCalendar). Then we'll have sthe ame base
to inspect it together.

Best regards
Janko

ok let me do it in steps and write it down while I do it.
.... an hour with lots of head scratching ....
Well no, this gave me a headache as I couldn't reproduce it until I
noticed I had to change the month in the calendar by a click on the <.


So finally the steps:

1- Make the calendar into a component:
viewCalendarComponent
        | e |
        e := WebElement new.
        e addDateInputFieldAspect: #date for: self observee.
        e addBreak.
        ^e

and use it:

viewCalendar
        | e |
        e := WebElement new.
        e addTextH1: #en->'Date input with Javascript Calendar example'.
        e addBreak.
        e add: self viewCalendarComponent .
        self pageFrameWith: e title: 'Calendar example'

Everything keeps working.

2- stick the WebDateInputField into a local variable so we can send it
messages later on.
viewCalendarComponent
        | e startDate |
        e := WebElement new.
        startDate :=  WebDateInputField new aspect: #date for: self observee.
        e add: startDate.
        e addBreak; newRow.
        ^e

All ok.

3- Now make the calendar update the component.
viewCalendarComponent
        | e startDate |
        e := WebElement new.
        startDate := WebDateInputField new aspect: #date for: self observee.
        e add: startDate.
        e addBreak; newRow.
        e registerId.
        startDate onChangePostAndUpdate: e id.
        ^e

In this case everything seems fine unless you change the month by
using < or >.

Then case the calendar just doesn't vanish and you have to refresh the
page.

BTW it first worked when sending ..andUpdate e instead of ..andUpdate e id.

Now I can't reproduce that.
       
Cheers,
