| [birt-dev] CheckIn: Fix Bugzilla Bug 121170 --- get column label from meta data object should return some user recognizable strings |
Description:
Why: Previously DataExtractionTask.getMetaData construct ResultMetaData from selectedColumns. In this way, we can't return column lable and types.
Fix: In DataExtractionTask.getMetaData calls extract() to get IExtractionResult and then call IExtractionResults.getResultMetaData to get IResultMetaData object. And we record the state that extract() has been called and return the extraction results in the succeeding call to extract().
