[zvitek]

Hi, im using react-router-component in version "^0.26.0" and work fine. But in IE9 does not work and teverything finish in last route "NotFound"
I have no idea what im doing wrong.

<Locations>
   <Location path={'/'} handler={HomePage} />
   <Location path={'/choose-trainee'} handler={ChooseTraineePage} />
   <Location path={/\/feed\/([0-9a-z]{10})/} handler={WallPage} matchKeys={['user_Token']} />
   <Location path={'*'} handler={NotFound} />
</Locations>

cases:
IE10 - mydomain.com/choose-trainee -> use handler 'ChooseTraineePage'
IE9 - mydomain.com/choose-trainee -> use handler 'NotFound'

Thx for help
