 into a JSON object you can utilize.

I'm switching to json, and you're right, it is much easier to handle!

Hope that's helpful. There are much better explanations in the API
documentation, and people here in the group who can articulate it much
better than i.

 Thanks for the explanation.

 I was wondering: a better solution is may be to use json? What do you

 Hi,

 I have a little problem. I want to give the content of an array to a new
 page through a form. The javascript code is:

     this._view.selectedPicts.setAttribute('value', picts);

 I retreive the content using mod_python:

     fields = util.FieldStorage(req)
     selectedPicts = fields['selectedPicts'].split(',')

 All works fine under Firefox and Safari/konqueror, but fails under IE8:

 Firefox:

 fields={'numAdherent': [Field('numAdherent', '20')], 'numEvenement':
 [Field('numEvenement', '2')], 'selectedPicts': [Field('selectedPicts',
 'P4052858.JPG,PB135158.JPG,photo20-08-03_DSC5719net_redimensionner.jpg,_DSC0222.jpg,p1010005.jpg')]}

 IE8:

 fields={'numAdherent': [Field('numAdherent', '20')], 'numEvenement':
 [Field('numEvenement', '2')], 'selectedPicts': [Field('selectedPicts',
 '[object]')]}

 The strange thing is if I log 'picts' before sending the form, it is
 correct, even under IE8!

     console.debug(OrderingController._submit(): picts= + picts);

 Firefox:

 2009-11-0 12:53:55,198::DEBUG::OrderingController._submit():
 picts=P4052858.JPG,PB135158.JPG,photo20-08-03_DSC5719net_redimensionner.jpg,_DSC0222.jpg,p1010005.jpg

 IE8:

 JOURNAL : 2009-11-0 12:55:10,67::DEBUG::OrderingController._submit():
 picts=P4052858.JPG,PB135158.JPG,photo20-08-03_DSC5719net_redimensionner.jpg,_DSC0222.jpg,p1010005.jpg

 So, why do I get the wrong string in my form field under IE8? What should I
 use instead of just 'picts'?

 Thanks,
