Re: Hidden XForm controls

Hi Jonathon,

there are two questions to your answer (at least :)

1) If by a hidden form control, you mean something like a hidden control 
in html forms: you don't need such a thing in the xforms world.
In html, such a field is just to add a name/value pair to the data. You 
can just put your data in the instance, there is no need for it to be 
bound to a control.
If you want that data to be calculated, you can define a binding that 
does so. (in the binding tab of the data navigator) no need to associate 
a control with the binding.

2) If you want a control that is visible, only when a certain condition 
or state in the instance occurs, than xforms:toggle is what you need. 
toggle isn't yet supported in OpenOffice.org though.
