Try this, which is way cleaner too: Get that switch out of the render in a function and just call it passing the params you want. For example:
renderSwitch(param) {
switch(param) {
case 'foo':
return 'bar';
default:
return 'foo';
}
}
render() {
return (
<div>
<div>
// removed for brevity
</div>
{this.renderSwitch(param)}
<div>
// removed for brevity
</div>
</div>
);
}
