Hi All

I am doing some work on CForms.

I have now got AJAX-type submission via IframeIO in Dojo working for
forms that have file-upload controls in them.

I am aiming to get progress-bars working for Upload Widgets in Cocoon
..... (there is a ProgressBarWidget in the new Dojo 0.4.0 :-) )


and I have several problems ......


a repeater, select files for them, then submit them all in one go.

One problem is, that if you have file-upload controls on a form, that
have a file selected, they get submitted when you click on the
repeater's add button, as these action-events submit the whole form.

I would like to change this behaviour but do not know if this will
break some other usecases.

While working on the CForms Widget, to get IframeIO working, I
switched to using Dojo's built-in form preparation code (instead of
cocoon.forms.buildQueryString). Dojo has equivalent method that can

filter to be used when submitting an action-event.

Can you think of any usecases where sending only the minimal
button-event would break existing CForms functionality ?

But meanwhile, I am trying to get some sort of Upload Repeater working The usecase is that a user may add a number of file-upload controls to take a filter function as an argument, meaning we could have a special

IIRC Dojo's built-in function doesn't allow to specify what input
triggered the form submit, which is absolutely needed for CForms to

for quite some time and it may allow it now.

properly handle fd:submits and fd:actions. Now I haven't looked at Dojo

Hi Sylvain

I am not sure I get your point ..... sorry





Or am I missing something ? :-)

regards Jeremy

I do not propose that the behaviour of the full submit button is changed, only action-submits (maybe only action-submits in repeaters). In these cases, I am trying to work out if only the hidden 'forms_submit_id' field could be sent, instead of the whole form (which gets no validation at this stage anyway). Alternatively, action-submits could be made to use a special filter to remove file-upload controls from their submit.
