Bug 150899 Cannot bind data values to chart series, which causes chart preview fail.
How to reproduce it? 1. Create a new chart, bind it with valid data set. 2. Assign the valid data values to category series and value series. Current result: 1. There is no chart live preview in chart builder. It still uses the default sample data. 2. Preview, dataset invalid exception is thrown out. Investigation: It is perhaps caused by ResultSetWrapper.java. There is no initializeMeta( ) in the Constructor.
