DS.clearAllFilters() or DS.clearFilter resetting the Data Source Initial View in Design Studio 1.5

Hi,

DS.clearAllFilters() or DS.clearFilter resetting the Data Source Initial View in Design Studio 1.5.

I have selected only some measures from data source. Then applying filters on the data source based on the selection made in the drop down list. On button "Reset" click i reset the data source using any of the DS.clearAllFilters() or DS.clearFilter  method. I am surprised that data source getting reset as Initial View first time. How to overcome with this.

And also i am looking for the some functions like add and remove Measures dynamically not the dimensions.

Finally i want to display data on Crosstab not on Chart otherwise we can do dataSelection for chart.

Design Studio Version : 1.5

BI Version: 4.1 SP 04 Patch 2

Thanks
