Brian Minchau commented on XALANJ-2067:
---------------------------------------
Via JAXP the parameter is set before the transformation in invoked:
transformer.setParameter("data", doc);
In the stylesheet is:
<xsl:param name="data" select="/.."/>
The value in the select looks a bit strange, but in any case the "data"
parameter should be set in the Java code via JAXP, over-riding the xsl:param in
the stylesheet.
It looks like that JAXP parameter setting should persist from one transform to
the next.
This looks like legitimate bug.
