T5: RadioGroup and null?
I'm using T5.0.14 and I'd like to get back null from a RadioGroup if the
user didn't click on any radio-buttons, but it seems the RadioGroup doesn't
support this?
<t:RadioGroup t:value="selection">
<input t:type="Radio" t:value="true" />
<input t:type="Radio" t:value="false" />
</t:RadioGroup>
This return false if no selection was made by the user.
regards,
Onno Scheffers

Hi Uli,
I figured any Object-type, including a Boolean, could be set to null, but
indeed when I change the type to a String it works.
Thanks a lot.
regards,

Boolean values cannot be set to null. If selection is a boolean variable
then it's always false except when it gets set to true. Use some other
type for your variable (e.g. String and parse that to boolean if it's not
null, use literal:true and literal:false in your radios). This will work.
