Bug 200290 The warning message "A Column Binding Name as xxx already exist" should occurs while input the column binding name but not the expression[0001]
Description: The warning message "A Column Binding Name as xxx already exist" should occurs while input the column binding name but not the expression[0001] Build number: 2.2.1.v20070817-0630 Steps to reproduce: 1, New a table binding on a dataset 2, Insert a data item and input a already existed name such as CUSTOMERNUMBER 3, Specify the expression Expected result: In step2, a warning message: "A Column Binding Name as xxx already exist" should occurs to warning the user Actual result: In step3, the warning message occurs I think we should pops up this message during inputting column binding name but not inputting column binding expression. Hope to enhance that.
