In XPath
1.0 default namespaces
are not used for QName expansion and so
the functions
in our examples should always contain the bpws:
prefix and xmlns:bpws
should
be explicitly declared.
From
Section 2.3 of XPath 1.0 specification:
"A
QName in the node test is expanded into
an
expanded-name using the namespace declarations from the expression
context.
This is the same way expansion is done for element type names in start
and
end-tags except that the default namespace declared with xmlns
is not used: if the QName does not have a
prefix,
then the namespace URI is null (this is the same way attribute names
are
expanded). It is an error if the QName has
a prefix
for which there is no namespace declaration in the expression context."

Fixing Typos in getVariable*() in BPEL examples

Issue - 102 - Fixing Typos in
getVariable*() in BPEL
examples
Status:
open
Date added: 9 Mar 2004
Submitter: Alex Yiu
Date submitted: 08
March 2004
Description: There
seem to be
typos in our BPEL examples
"bpws:getVariableProperty(stockResult,level) > 100"
"bpws:getVariableProperty(stockResult,level) >= 0"
"bpws:getVariableData(orderDetails) > 100"
We need to put quotations on function
parameters.
It becomes like:
"bpws:getVariableProperty('stockResult','level') > 100"
"bpws:getVariableProperty('stockResult','level') >= 0"
"bpws:getVariableData('orderDetails') > 100"
In some of the examples the "bpws:" is
actually extra and incorrect. The prefix-namespace mapping of a
function call
in XPath typically inherited from that of the hosting element.
