Problems with Wait inside Switch inside While

Question

Hi!
I have implemented a process that does something like this (BPEL 10.1.3.3):
1. reads some data and sets some variables
2. has a While activity that tries for 5 times to post some xml message to specified URL
3. if it doesn't succeed than set some error parameters and continue
The way I've done this:
[xml]
<while name="While_1"
condition="bpws:getVariableData('RetryNum') &lt;= 6 and bpws:getVariableData('ReturnStatusCode') != '202'">
<sequence name="PostXML">
<switch name="AbortDesision">
<case condition="bpws:getVariableData('RetryNum') > 5">
<assign name="AssignFailure">
<copy>
<from expression="string('202')"/>
<to variable="ReturnStatusCode"/>
</copy>
+ some more copy operations...
</assign>
</case>
<otherwise>
<sequence name="Sequence_3">
<switch name="TimeoutDecision">
<case condition="bpws:getVariableData('RetryNum') > 1">
<sequence name="Sequence_2">
<wait name="Wait2S" for="'PT2S'"/>
</sequence>
</case>
<otherwise>
<empty name="Empty"/>
</otherwise>
</switch>
<bpelx:exec name="PostXML" language="java" version="1.4">
<![CDATA[try     
Some Java code that calls the URL and sets some variables including ReturnStatusCode
}]]>
</bpelx:exec>
<assign name="IncreaseCount">
<copy>
<from expression="bpws:getVariableData('RetryNum') + 1"/>
<to variable="RetryNum"/>
</copy>
</assign>
</sequence>
</otherwise>
</switch>
</sequence>
</while>
[xml]
What I've tried to achieve is: for the first time don't wait, just execute Java code. If status code != '202' than wait 2 seconds and retry. Do this for five times. If I don't succeed then I should set statusCode variable to 202 manually and then continue the process. The problem is that the last wait never ends. Even if I change condition in switch name="AbortDesision" to <case condition="bpws:getVariableData('RetryNum') > 2">it is the same, the first wait never ends. Can someone please tell me how to solve this. If it is important, the java code throws an exception that is not handled. Could this be the problem?
Thank you in advance,
BB

Answer 1

I found out one very interesting thing:
When I changed condition case condition="bpws:getVariableData('RetryNum') > 5" to case condition="bpws:getVariableData('RetryNum') = 6" everything is working OK.
Nice, ha :)
