Birt upgrade 4.3 to 4.5 Error in BirtStr.trim function

We use BirtStr.trim function in all our reports and it is failing on 4.5 (Eclipse Mars).


 


Stack trace:


 


BirtStr.trim(fname+" "+lname)


org.mozilla.javascript.ConsString cannot be cast to java.lang.String

   at org.eclipse.birt.report.engine.executor.ExecutionContext.addException(ExecutionContext.java:1245)

   at org.eclipse.birt.report.engine.executor.ExecutionContext.addException(ExecutionContext.java:1224)

   at org.eclipse.birt.report.engine.executor.QueryItemExecutor.executeQuery(QueryItemExecutor.java:96)

   at org.eclipse.birt.report.engine.executor.TableItemExecutor.execute(TableItemExecutor.java:62)

 


 


This code works fine in 4.3 version (luna eclipse)


 


 


When we change the code to use the BirtStr.concat function it works fine.


BirtStr.trim(BirtStr.concat(fname," ",lname))


 


 


Effort of making code changes are really high. 


 


Any recommendations ?

  • Issue 1:


    BirtStr - all functions


     


    BirtStr.trim(fname+" "+lname)


     


    Error


    org.mozilla.javascript.ConsString cannot be cast to java.lang.String


     


    Work around:


    BirtStr.trim(BirtStr.concat(fname," ",mname))


     


     


     


     


  • Hi,


     


    If you google the error message, you'll find out that with Rhino 1.7.4, now included in BIRT 4.5, Rhino has changed substantially how it handles Java to Javascript object conversion. I don't know of a workaround, except changing the way you concatenate strings.


     


    Hope this helps,


     


    P.
