xforms:input initial value

Tamas,

If I read correctly, it looks like you think the initial value for a control could be read from instance node A while populating node B of the (or a different one) instance with a submitted value. I do not think this makes much sense from modeling point of view - there should be just a single instance node used for both "tasks". What does make sense though is to populate default values of instance dynamically upon (say) form load.

Hello,

I am quite novice to XForms.

Now I would like to pre-set the value of an <xforms:input /> field. As far as I read, I must bind the field
to a model element using either the ref or the bind attribute. Unfortunately, I cannot use the ref because
I already use that to save the results to the output model:
<xforms:input incremental="true" model="outputModel" ref="BBDemoSchema:CUSTOMER_NAME"/>
You can find the corresponding model below the mail.

I guess the solution must be using the bind attribute. But that is a bit tricky: the corresponding data is
also called CUSTOMER_NAME. It resides in the very same namespace. How can I trick that? How can I
set the initial value from the input CUSTOMER_NAME, and set the result to the other one?

Tamas

You can always use <xforms:setvalue/> to insert values into a node in the outputModel. Another option is to copy the values from inputModel into outputModel using <xforms:bind/> - that way your XForm could mirror (part of) the inputModel in the outputModel.

Hi Alexander,

This thing that the initial value of a control is being read from node A - that belongs to the model inputModel -
while populating node B - that belongs to outputModel - does make sense in Suns worklfow engine. The thing
is that the initializing assignments can occur in a different layer from the Xfroms: I just assigned values to the
nodes of the ouput mode. So this way I could initialze my forms. Thank you for your help!

Thanks,
Tamas
