From the J2EE developer's point of view it looks like return back to 2000s,
to Servlets and tons of HTML/CSS markup in code. IMHO all advanced Java
developers agree that moving HTML markup from Java code into separate JSP
files was great step forward.

Hello!
You can do it in many ways:
1. Create an empty placeholder for hidden input (div at the bottom of your
form). You can then easily replace content of this div and don't care about
multiple inputs:
addElement: function () {
$(totalsContainer).update('input type=hidden id=finaltons
When using v1.6.0.2 and serializing a form with a multiple select list,
I would get its value like myselect[]=foomyselect[]=bar.
In v1.7.0.0 it's posting the value like myselect[]=foo,bar. This does
not work properly on the backend (Rails).
Is this expected behavior?
Yes, Prototype 1.7
That is not conveniently tied to any event handler, so what is the
convenient means of disconnecting it, as in __eventHandler.stop(); ?
Sorry, I've not completely understood this phrase. I'll repeat myself:
// start observer - bindAsEventListener isn't needed
this.__z__handleSubmit =
Is this correct?
this.__z__handleSubmit = this.form.on('submit', this.__handleSubmit.
bindAsEventListener(this));
Is the bindAsEventListener necessary? I want to get back the Event
Handler so I can later destroy it with:
this.__z__handleSubmit.stop();
this.__handleSubmit.bind(this)
In short words, B element after dragging becomes z-index: 0 instead of
original z-index: auto and establishes new local stacking context. The
logic in startDrag()/finishDrag() methods should be fixed to properly
restore initial z-index for z-index: auto (now it defaults to 0).
--
You received
How can it be fixed?
in startDrag() (dragdrop.js):
if (this.options.zindex) {
// FIXED z-index: auto - z-index: 0
// was this.originalZ = parseInt(Element.getStyle(this.element,
'z-index') || 0, 10);
this.originalZ = Element.getStyle(this.element, 'z-index');
Maybe try Object.toJSON() and then String#evalJSON()? You'll be
transferring to main context single string.
