DS 1.3 SP01 get selected member in Chart

Hi,

We are in DS 1.3 and SP01.

We have two charts CHART1 (from DS_1) and CHART2 (from DS_2).

CHART2 refresh based on the selection in CHART1.

Selection mode is single in CHART1.

I have below code in Onselect of CHART1.

DS_2.setFilter("0FISCPER3", CHART1.getSelectedMember("0FISCPER3").internalKey);

The code is not working as "CHART1.getSelectedMember("0FISCPER3").internalKey" always return "(ALL_MEMBERS)" irrespective of the section.

Has anyone faced the same issue? How to solve it?

Thanks and Regards,

Suresh.
