Re: Bindings to non-existing instance:data

Greetings Roman, the section describing the xforms-form-control-initialize Event describes what happens.
[ http://www.w3.org/TR/xforms/slice4.html#evt-formControlInitialize ]

There are two basic situations which can lead to there being no instance 
data node for the UI element to bind to.

1) No <instance> was supplied in which case an instance data node will be 
created when the UI element is initialised.
2) There is an <instance> but there is nothing for the UI element to bind 
to, in this case the UI control should behave as if it was bound to a 
non-relevant node.

Regards, Roland

Hello,

I have quite a short question. I thought that I read it somewhere in the 
spec but I couldn't find the passage again.
What happens if I refer from a xform control to an element in my 
xforms:instance, which doesn't yet exist? Is it (the instance 
element)created when the user fills in the form control?

Or do I have to define a trigger, whichs creates the needed instance 
elements before?

wbr,
Roman
