Null exception in SfRadioButton when checked status set by Parameter

[Bruno]

Hi

When I set the Checked value of a SfRadioButton from a parent component I get the exception from the builder: 
"System.NullReferenceException: 'Object reference not set to an instance of an object."

The following code is your own example but with stringChecked set via Parameter.

Thanks, Bruno​

<SfRadioButton Label="Option 1" Name="options" Value="card" @bind-Checked="stringChecked"></SfRadioButton>
<SfRadioButton Label="Option 2" Name="options" Value="cash" @bind-Checked="stringChecked"></SfRadioButton> 
@code {
   [Parameter]
   public string stringChecked { get; set; } = "check2";
}

P​arent component:
<TestComponent stringChecked="card" />

Sorry, it was my fault, a beginner's fault!

I called TestComponent multible time for several parameters.
Obviously thats not legal.

<TestComponent stringChecked="card" />

<TestComponent anotherChecked="check1" />  //>> not null exception in the tree builder
