Tabs are not working after upgrade to DS 1.3

Question

Hi All,
I have 4 tabs Region, Plant , Plant section and Unit.
When I select one tab it sets as a filter values to the next tab and displays data(drilldown).
We also have a back button in the each level to go back .
It was working perfectly in DS 1.2 and we have upgraded to DS 1.3 and now when I click on the back button it comes back to same screen.
here is the steps.
  Step 1) select Region data will be displayed based on selected Region
  step 2) select Plant data will be displayed based on selected plant
  step) click Back button on Plant screen by disabling plant tab and enabling region tab.
Once I click on Back to Region button it quickly goes to Region tab and then come back to Plant tab.
not sure why this is happening.
please advise.
Thanks,
Manju

The chart select event fires again when it's redisplayed in tab 2.
Do this in your chart select event to prevent it:
var temp = REGIONBU_CHART1.getSelectedMember("0MAINTPLANT").internalKey;
if(temp!=XOperatingAsset_Plant){
     Tab_3.setEnabled(true);
     Tab_1.setEnabled(false);
     Tab_2.setEnabled(false);
     Tab_4.setEnabled(false);
     Tab_5.setEnabled(false);
            XOperatingAsset_Plant=REGIONBU_CHART1.getSelectedMember("0MAINTPLANT").internalKey;
     LV4_REGITPMCOMTREND.setFilter("0CALMONTH", {"low":XMetric_Period_Low,"high":XMetric_Period_High});
     LV4_REGITPMCOMTREND.setFilter("0MAINTPLANT",REGIONBU_CHART1.getSelectedMember("0MAINTPLANT"));
     LV4_REGITPMCOMTREND.setFilter("ZMETRICID","PMR02");
     LV4_REGITPMCOMTREND.setFilter("0MAINTPLANT__ZPMFNORG", XFunctional_Org);
     LV4_REGITPMCOMTREND.setFilter("0MAINTPLANT__ZPMOPAREA", XOperating_Area);
}else{
  XOperatingAsset_Plant = "";
