Comment 1 Ritesh Adval 2006-09-06 01:45:58 UTC 
Not a bpel project bug but validation bug in bpel editor.
changing subcomponent.

Should we have a subcomponent called "validation"?
Comment 2 Praveen Savur 2006-09-11 19:14:15 UTC 
fixed on friday. Each validator now validates within a transaction, so this
problem does not occur.
Comment 3 Andrey Yamkovoy 2006-09-13 11:56:49 UTC 
fixed
