Bug 160193 Parameter name is changed with data type
Steps to reproduce: 1.New a sample data source 2.New a data set with below query: select * from CLASSICMODELS.CUSTOMERS where CLASSICMODELS.CUSTOMERS.CUSTOMERNUMBER = ? 3.Switch to parameters in data set editor, a parameter is created automatically 4.Double click the parameter, click "..." button behind the "Linked to report parameter", note the default name of report parameter is "param1". Click "cancel" to destory "new parameter dialog" 5.Change data set paramter type to Any, and click "..." again Expected result: Default name of report parameter is "param1" Actual result: Default name of report parameter is changed to "NewParameter1"
