[rules-users] String.format question in the RHS

[Joe White]

What error do you get in the rule or does it just not format correctly?

Subject: [rules-users] String.format question in the RHS

 

Hello,

 

Can anyone see an issue with the following RHS?  The String.format is
failing.  I've copied it straight into java to verify my intentions and
it works there.

 

What I'm trying to accomplish is to concatenate the string UH005 with a
sequence number that is a fixed 10 digits, zero filled.  So if
CurrentClaimSeq_48 is the number 123, then I expect that TRN02_Check...
would be populated with UH0050000000123.

 

Again, this is working fine in straight java, but not in a rule.  What
am I missing?  Is there a better way to try to accomplish this in a
rule?

 

rule "L1000_TRN02_UHC_BPA"

    dialect "mvel"

    when

        CLM_835_SUPP( seq : currentClaimSeq_48 != ( null ) )

        CLM_DET_LOAD( )

        trn : x221TransactionHeader_TRN_ReassociationTraceNumber( )

    then

        trn.setTRN02_CheckOrEftTraceNumber( "UH005" + String.format
("%010d", seq) );

end

 

 

Here are the data types of the two fields involved.

 

private Integer CurrentClaimSeq_48;

 

public String TRN02_CheckOrEftTraceNumber;

 

Thank you!

 

Dean
