Bug 181361 Exception is thrown out in Chart builder when you set all null values for Value Series [0001]
Description: Exception is thrown out in Chart builder when you set all null values for Value Series. Build number: 2.2.0.v20070405-0630 Steps to reproduce: 1. Create a Bar Chart, set all null value data for Value Series. Expected result: No exception is thrown out. Actual result: Exception is thrown out (See the screenshot). Error log: N/A
