hi carsten,
check out the 'setvalue' action and use a second instance, e.g. sth. like:
<xf:setvalue ref="instance('i-2')/item[1]" value="instance('i-1')/item[1]"/>
you'd have to do this for every item which value should be copied.
another approach would be to preprocess the instance data with XSLT in
order to select only the data you need to edit. you could plug in an
URIResolver which performs the XSLT transformation. the advantage would
be to have an instance not too large to be processed effectively by
Chiba. but then you can't decide within the XForm which data to edit.
this is only possible with 'relevant', since it's not a flag, but a
dynamically computed property.
hope this helps, uli.

Hello,
ok, I just tested and it works. It's a pitty that relevant is
default="true". The XML-Document I have is not "small".
Is there a way of filling an instance out of an other instance?
What I mean is, load the XML as an instance, and use this in an other
instance at the same XForm, using only the values of instance#1?
I tried a bit, but maybe I am to tired this evening or it is not possible.
Again, any suggestions would help.
Cheers,

Hello Carsten,
If the xforms relevant attribute on any instance XML element evaluates
to false(), then when the instance is submitted those elements will not
be included. Check out
http://www.w3.org/TR/xforms/slice6.html#model-prop-relevant
http://xformsinstitute.com/essentials/browse/book.php#ch08-77004
It is pretty straight forward to "turn off" the submission of certain
elements based on combinations of XPath functions, and this works as
expected in Chiba. If you need an example, I can cook one up. Also,
check out /forms/wizard-with-relevant.xhtml in the default distribution
of Chiba.

Hello,
I just test around with Chiba and XForms. Now I have a little probelm:
- I have an instance with a XML-Tree with data
- The Form should only use "some" of the data.
- The XForms should only submit some specified data.
Just an example:
instance:
<data>
<val1>test</val1>
<val2>test</val2>
<val3>test</val3>
<val4>test</val4>
</data>
The Form should only display input's for <val1> and <val2>. And if it is
sent, the sent XML should only have <val1> and <val2> in it, not <val3>
or
<val4>.
I just have one big dump of some XML-Instance-Data, and I can't split it
up (system-Requirements), but I just need to provide several ways of
Forms
for SOME of this data.
Hmm I hope you know what I mean, and I hope someone could help me.
