[chirp_devel] RadioSettingValueString in RadioSettingGroup

Hello, As in many other drivers I use RadioSettingGroup for additional memory settings.I have to map an hexadecimal string of 4 chars to each memory.So I tried to add a RadioSettingValueString in the RadioSettingGroup but it does not seem to work as expected. No stringbox and no errors in console.This drives me crazy at this stage. Any idea what's wrong? Cheers.
