Problem with setting selected value in a Radio button

Hi,

We've build an application using a Tab strip.

We enabled filtering using both the selected value in a Chart and a Radio Button group.

Our current problem is that after we use the selected member in the of the Chart to set a filter in a datasource  using the following code in the "on select section" of the chart :

" POC_DS2.SETFILTER("0CALYEAR",CHART_2.getSelectedMember("0CALYEAR"));.

The selected item in the radio button no longer corresponds with the selected filter in the Chart.

We've tried the following code in the "on select" section of the chart to allign the selected value in de RadioButton and the Chart. But that doesn't seem to compile.

RADIOBUTTONGROUP_1.setSelectedValue(CHART_2.getSelectedMember("0CALYEAR"));

Can anyone provide me with a solution for this problem.

Regards,

Freek
