Hi,
I am about ready to crack from too much Xforms in Open Office work I
have to say.
Why the does the following give a response of 'This is an invalid
binding expression':
The drawn element:
<draw:control draw:style-name="defaultCBCfield"
draw:text-style-name="P4" svg:width="3.5cm" svg:height="0.498cm"
text:anchor-type="paragraph"
draw:control="[EMAIL PROTECTED]"></draw:control>
the sun forms element:
<form:text form:name="[EMAIL PROTECTED]"
form:control-implementation="ooo:com.sun.star.form.component.TextField"
form:id="[EMAIL PROTECTED]"
form:convert-empty-to-null="true"
xforms:bind="[EMAIL PROTECTED]"
xmlns:number="urn:oasis:names:tc:opendocument:xmlns:datas:1.0">
<form:properties>
<form:property
form:property-name="DefaultControl"
office:value-type="string"
office:string-value="com.sun.star.form.control.TextField"></form:property>
</form:properties>
</form:text>
the xforms binding:
<xforms:bind id="[EMAIL PROTECTED]"
nodeset="/in:Invoice/cac:PaymentMeans/cbc:InstructionID/@schemeAgencyID"
required="false()" type="xsd:string"
xmlns:number="urn:oasis:names:tc:opendocument:xmlns:datas:1.0"></xforms:bind>
please note that all sorts of variations of this binding does not work:
//cac:PaymentMeans/cbc:InstructionID/@schemeAgencyID
and
//cbc:InstructionID/@schemeAgencyID
and
//in:Invoice/cac:PaymentMeans/cbc:InstructionID/@schemeAgencyID
don't work either.
Is it because this element does not exist in the document?
Well no, here is a fragment with it here:
<cac:PaymentMeans><cbc:ID/><cbc:PaymentMeansCode
listURI="urn:oioubl.codelist.paymentmeanscode-1.0"/><cbc:PaymentDueDate/><cbc:PaymentChannelCode
listURI="urn:oioubl:id:paymentchannelcode-1.0"/><cbc:InstructionID
schemeAgencyID=""/>
if I take the whole xml instance out and running it over this xslt:
<?xml version='1.0' encoding='utf-8'?>

</xsl:template>
<xsl:template match="@schemeAgencyID">
yes
</xsl:template>
</xsl:stylesheet>
the output I get is yes, so that means the binding does exist.
now why is this happening???
Well partially I suppose it has to do with namespace binding, for
example I can make the binding to my attribute is correct if using the
complete path /in:Invoice and so forth to the attribute but only if my
namespace prefix in is declared in the context of the element of the
element invoice. Thus it does not help at all if my namespace prefix
is declared on the document element of my open office document. This
however is a problem because I am generating the XML instance from an
XSLT processor and despite putting the namespace declaration both
places the processor can make its own mind up, in this case putting
the namespace in the document element. Reasons why this might be
problematic, well, not sure if moving it around or trying to take it
out of the document element isn't going to lead to a situation where I
am running around trying to chase bugs for the next week and I am
supposed to deliver on the 26th, the other reason is that I am not
sure if all the things I am doing in my program can be made to work
with namespaces not output on the document element of my Open Office
document.
Cheers,
Bryan Rasmussen
