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

I got it to work in mvel. You need to pass the second argument as an mvel array (note the curly braces) for it to recognize the method signature. Here is a rule that works for me: import java.util.Map; import java.util.ArrayList; import java.util.List; import java.lang.String; import com.recondotech.droolsTest.TestInput; import com.recondotech.droolsTest.TestConts; import com.recondotech.droolsTest.TestMap; dialect "mvel" rule "map list test rule" salience 155 when TestInput(val : val!=null) then String result = String.format("%010d",{val}); System.out.println(result); end From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Wolfgang Laun Sent: Friday, August 19, 2011 9:34 AM To: Rules Users List Subject: Re: [rules-users] String.format question in the RHS Do not use dialect "mvel". -W 2011/8/19 Dean Whisnant <dean(a)basys.com&gt; 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!
