Hi all,
I am running into a case where I need to check if a variable has been
initialized in a *<bpel:condition />*. The variable is first defined inside
*<bpel:variables>* without inline initialization. The following condition
is then added to a *<bpel:repeatUntil>*:
($variableIf_2Out.parameters/getStatusResult/status = 'CLICKED')
However *$variableIf_2Out* may not have been initialized as the
*<bpel:invoke>* activity that outputs it is conditional and may not have
been encountered yet.
I tried with:
(exists($variableIf_2Out) and
$variableIf_2Out.parameters/getStatusResult/status = 'CLICKED')
but that didn't seem to help (the expression language is set to
*"urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0"*).
In a desperate attempt I tried:
(exists(bpel:getVariableData('variableIf_2Out', 'parameters')) and
$variableIf_2Out.parameters/getStatusResult/status = 'CLICKED')
and even:
<bpel:condition xmlns:bpws="
http://schemas.xmlsoap.org/ws/2004/03/business-process/";>
(exists(bpws:getVariableData('variableIf_2Out', 'parameters')) and
$variableIf_2Out.parameters/getStatusResult/status = 'CLICKED')
</bpel:condition>
That didn't get me anywhere either (according to the logs the function is
not defined or arguments cannot be matched).
Is there a way in ODE by which a variable can be checked to have been
initialized?
Thanks,
- Stan
