Tagakov / My SO question RxJava

Stack overflow question about rxjava and retrofit. How to transform observable's error to another observable?

	How do I transform observable's error to another observable?

	I am trying to implement algorithm showed on scheme below:

	![Block scheme][1]


	[1]: http://i.stack.imgur.com/777p5.png

	I am using a tutorial named Grokking RxJava to start my learning and found that flatMap operator can convert one Observable returning by Retrofit into another which allows me to do a chain of invocations of server methods. But in the tutorial chaining methods always return success result. How I can do the same chaining if one of the remote methods returns error?
