Hi Luca,
Indeed this looks like a bug in the BPEL 1.1. compatibility area.... for
now I'd recommend using the BPEL 2.0 syntax ($variable.part/...)
Can you file a Jira issue? That way, it will get on our TODO list.
thanks for reporting,
alex

Hi all,
I have been doing some more testing on this issue, and I
discovered that simply changing the notation of the assign
modify the behavior of the engine.
Using a:
<assign name="d0_InputData">
<copy>
<from><literal>
<xsd:PAAM_in xmlns:xsd="http://www.a-ware.org/airbus/xsd";>
<xsd:frequency>4</xsd:frequency>
<xsd:templateFile>string</xsd:templateFile>
<xsd:parameters>
<xsd:name>string</xsd:name>
<xsd:value>string</xsd:value>
</xsd:parameters>
</xsd:PAAM_in>
</literal></from>
<to variable="n0_PAAM_data_in"
part="body"><query>/</query></to>
</copy>
<copy>
<from variable="ProcessInstantiation_data_out"
part="body"><query>/xsd:templateFile</query></from>
<to variable="n0_PAAM_data_in"
part="body"><query>/xsd:templateFile</query></to>
</copy>
</assign>
output this weird message
The message received by paam is
<xsd:PAAM_in xmlns:wsdl="http://www.a-ware.org/bpel/airbusTest/wsdl";
xmlns:xsd="http://www.a-ware.org/airbus/xsd";>
<xsd:templateFile>pluto</xsd:templateFile>
<wsdl:frequencies>
<xsd:frequency>7.1</xsd:frequency>
<xsd:frequency>3.2</xsd:frequency>
</wsdl:frequencies>
<wsdl:parameters>
<wsdl:parameter>
<xsd:name>prova</xsd:name>
<xsd:value>bene</xsd:value>
</wsdl:parameter>
</wsdl:parameters>
</xsd:PAAM_in>
While if I use the other notation for the assign
<from>$ProcessInstantiation_data_out.body/xsd:templateFile</from>
<to>$n0_PAAM_data_in.body/xsd:templateFile</to>
I get the right message:
The message received by paam is
<xsd:PAAM_in xmlns:xsd="http://www.a-ware.org/airbus/xsd";>
<xsd:frequency>4</xsd:frequency>
<xsd:templateFile>pluto</xsd:templateFile>
<xsd:parameters>
<xsd:name>string</xsd:name>
<xsd:value>string</xsd:value>
</xsd:parameters>
</xsd:PAAM_in>
I thought that the two format of the assign were equivalent...
1> <from variable="ProcessInstantiation_data_out"
part="body"><query>/xsd:templateFile</query></from>
1> <to variable="n0_PAAM_data_in"
part="body"><query>/xsd:templateFile</query></to>
2> <from>$ProcessInstantiation_data_out.body/xsd:templateFile</from>
2> <to>$n0_PAAM_data_in.body/xsd:templateFile</to>
And why if I use the first format it outputs such a weird message?
Thank you,
Luca
