Re: BPEL - How work activity ?

[Matthieu Riou]

Hi Anne,

So first you don't need to specify the namespace for the function. And it
even seems that specifying it leads to an incorrect result, which is
probably a bug. But for now just don't give any namespace for your functions
and that should work.

The second problem is that our implementation of the <if> activity doesn't
yet reflect the changes in the latest WS-BPEL draft so you'll need to write:

<if>
 <condition>...</condition>
 <then>...</then>
 <else>...</else>
</if>

I've created an issue to track this here:
http://issues.apache.org/jira/browse/ODE-95. Add yourself as a watcher to be
notified when this is corrected (hopefully shortly).

Hi,

I would like to test the if activity but I have strange results.
If I write a BPEL process as follow (I run it into Servicemix) :

<variable name="errorMsg" type="xsd:string"/>

<assign name="test">
<copy>
  <from>
   <literal>Toto</literal>
  </from>
  <to>$errorMsg</to>
</copy>
</assign>

<if name="coherencePrecision">
   <condition>fn:true()</condition>
    <sequence>
     <assign name="assignPrecision">
      <copy>
       <from>
        <literal>Titi</literal>
       </from>
       <to>$errorMsg</to>
      </copy>
     </assign>
    </sequence>
   <else>
    <assign>
     <copy>
      <from>
       <literal>Tata</literal>
      </from>
      <to>$errorMsg</to>
     </copy>
    </assign>
   </else>
  </if>

I get as result "Tata" !
So the condition fn:true() does not work !
My first question : must I prefix the xpath functions  with
xmlns:fn="http://www.w3.org/2005/xpath-functions"; ?

I also test these conditions with also strange results :
<condition>true()</condition> result : Tata
<condition>true</condition> result : Toto
<condition>fn:false()</condition> result : Toto
<condition>1 = 1</condition> result : Tata

So when I write <condition>true</condition> I get result : Toto : the BPEL
process does not execute the if activity and does not execute the else
activity !!!
How is it possible ???

Thanks in advance,

Anne.
