Tabs are not working after upgrade to DS 1.3

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
