Bug 142893 Text key not found when library and report use different resource files
The following scenario was tested with BIRT 2.1RC2: - New library, assign resource file "r1.properties" which contains key/value-pair "k1=v1" - New label in library, set text key of label to "k1" - New report, assign resource file "r2.properties" which does not contain key/value-pair "k1=v1" - Drag and drop label from library to report body - Preview Expected result: - Report shows "v1" Actual result: - Report shows nothing. If key/value-pair "k1=v1" is added to r2.properties, than "v1" is shown.
