Exception handler, construct and send shape

 

i have catchexception block in orchestration. within build exception message using construct shape , send message port direct message box bound

 

this working fine. until had add web service calls within exception block perform clean up. in addition existing shapes have 2 web service calls.

 

issue whenever exception thrown ends "uncaught exception..." message

 

the service instance remain suspended until administratively resumed or terminated.

if resumed instance continue last persisted state , may re-throw same unexpected exception.

inner exception: value cannot null.

parameter name: val

 

this thrown directly on construct shape(construct exception). if add expression shape right between construct , send ; , add valid statements there (like system.diag....eventlog..write etc) never above error

 

looks orchestration trying send constructed message before constructed.

 

any pointers?
