iReport Designer - problem between versions 4.0.2 and 4.1.1

[zaya]

Hello.

I have a very simple report, producing just a simple xls-list with several columns (in Detail Band) and headline (in Title Band), created and running with version 4.0.2..

After opening and configuring a TextField in the Detail Band (e.g. repartitioning of a Field in the Expression editor), as well as successful compiling and saving of the report, I executed him again on a 4.0.2. version.

Following error message (posted in parts only) appeared:

"ERROR - 1 - Errors were encountered when compiling report expressions class file: 1. Cannot cast from BigDecimal to String value = (java.lang.String)(((java.math.BigDecimal)field_USED_EU2.getValue())); //$JR_EXPR_ID=16$ <-------------------------------------------------------------------> 2. Cannot cast from Timestamp to String value = (java.lang.String)(((java.sql.Timestamp)field_IMPORT_DATE.getValue())); //$JR_EXPR_ID=21$ <--------------------------------------------------------------------> 3. Cannot cast from BigDecimal to String value = (java.lang.String)(((java.math.BigDecimal)field_TAG_CATEGORY.getValue())); //$JR_EXPR_ID=34$ <(...)"

 

The Expresssion Class was correctly configured, compiled and saved in 4.1.1, but throws an error in 4.0.2..

Additionally a change or correction of the Expression Class, according to the error message, only is possible in 4.0.2.!!!

Even if it is changed and saved in version 4.1.1., it will come to the same error message in 4.0.2!!!

 

How can this be fixed?

 

Best regards so far...
