What PRPC version you are on? Atleast in &.2.1 , i see that by default nothing i selected in runtime though in design time it shows first value as selected.

This is unless u select the checkbox called "Include option for Not Applicable", incase you select this, then this value will be selected by default.

Hi,

I have checked this on Pega 7.1.6 too.  By default no value gets selected.

Could you please share a screenshot?

Thanks,

One quick way to verify the behavior is to go to UI gallery and check the radio button example.

In 7.2.1 all the example related to radio button will come up without having any default option selected. So may be at your end you should first check the behaior in UI gallery

I had the same problem when i was using radio button for the first time in my application.

I did some changes in the cell properties(changing the orientation, label format, etc), none of them related to the default radio button selection and then after it started displaying without a default value, i don't know how that fixed it but that's how it happened for me.

When exactly do you see the value get selected?  Is it when a screen is first loaded or upon some other action?  When you see this, is the related property on the Clipboard updated?  Is it always the same radio button that's selected (same relative position or same value)?  Finally, can you check (with Tracer) if there are any activities or data transforms that may be initializing this property to the selected value?

Thanks!

Is source for radio button is Prompt/local list or through Datapage/RD/Clipboard page?
