… Even though I should know that It drove me crazy the last hour. It’s important to remember when using render in error handling with nested resources. The following actually does not work, since when calling render :action => “new” in the error handling, @b will not be set, an therefore render will fail (probably unless @b is not used at all)

It’s important to actually set @b in this case even though it is not actually needed for the create

Just nice to know, because it actually feels like calling a controller but it doesn’t.
