Paul,
Following up your usenet sussgetion:
<field column="id" template="${jc.fileAbsolutePath}${x.vurl}"
ignoreMissingVariables="true"/>
and to add more to what I was thinking...
if the field is undefined in the input document, but the schema.xml
does allow a default value, then TemplateTransformer can use the
default value. If there is no default value defined in schema.xml
then it can fail as at present. This would allow "" or any other
value to be fed into TemplateTransformer, and still enable avoidance
of the partial strings you referred to.
Regards Fergus.
