Orbeon throw the next error:

Failed to compile stylesheet. 1 error detected. Error at  of  oxf:/apps/sample-web/screen/scr_win/new/screen/screen.xml: XPath syntax error at char 40 on line -1 in
{...e-list-instance')/scr_tblpa...}:     Unknown system function instance()

instance() is an XForms function. The expression you are doing here is
an XSL expression. Since XSL has no function named instance(), you are
getting an error.

If you want to perform this expression, you will need to reference
information known to the XSL processor at the time it is run. (which
is before the XForms instance is created) Do you have an input that
you use to populate this instance, or is this information coming in
during the run time of the form? (my guess is the latter)

If this is information that you could only get while the form is
running, and you are trying to do this in response to some event fired
by the form, then you'll probably need to be looking at xf:insert and
xf:delete instead.

I got it Daniel!!!

Do you know about any example that could guide me (xf:include and xf:delete)???? or how can I modify the next example ( in Government forms).

<xsl:copy-of select="doc(concat('../forms/', doc('input:instance')/*/form-id, '/view.xml'))/*"/>

I'm novice in the xsl issues.


Any help!!!
THANKSSSSSSS IN ADVANCEE!!!

Where would the <xsl:copy-of
select="doc(instance('id-22-example-list-instance')/scr_tbl/par_avalue)"/>
need to be used? In most cases, the only "instance" you can access in
XSLT is the instance that was submitted. If an instance was submitted
from page A to page B, in the view of page B, you can access the
instance submitted from A.
