templates - wso2 - check if a sequence really exists -
i have scenario in esb wso2:
- a variable stored in registry called version
- s1 -> sequence of version1
- s2 -> sequence of version2
- serror -> sequence in case of error
if version == 1 s1 called if version == 2 s2 called if version empy s3 called
now issue is: if version == 3 got error:
sequence named value {name ='null', expression =get-property('seqname')} cannot found
beacuse s3 doesn't exist
my question is: way check if sequence exists?
thank you!
regards claudio
there no way check existence of sequence through existing mediators. if need that, can write class mediator , check synapseconfiguration object. case, can use switch mediator , add default case default sequence notify request has not supported version.
<switch> <case 1> <seq1> <case 2> <seq2> <case default> <seqdefault> </switch>
