It looks like getContextArgument(...) can still be null!

Hi Marcellus!

After testing VoiceRepeater I've realized that lines 58 and 64, which both try to retrieve the value of a context argument, can still raise a null exception error when the arguments are not defined. It happens despite the fact that the context itself exists. What if you make a double check?

When what arguments are not defined? Can you show me code use case that would cause the problem you are talking about?

return this.app.getContext("last_prompt") !== null
? this.app.getContextArgument("last_prompt", "last_prompt").value
: "um....I don't remember what I said!";

From the screenshot above, we can see that this.app.getContextArgument("last_prompt", "last_prompt") can be null despite this.app.getContext("last_prompt") being not, thus causing the error above.

Same for "prefixed_last_prompt".

Okay cool, now I understand more! I thought I mitigated this issue..... :-(
What are the steps you are doing to reproduce it? Does it happen every time?

[wisdal]

At first glance, I would say it doesn't work when I askWithList() or askWithCarousel().
Does it make sense?

And what I still do not understand is that my app is one step late. What I want to say is that 'replay' repeats what the app said two steps back rather than what it just said, thus causing the error above at the welcome speech, for instance, as there was no response prior to it.

Right now things are busy for me at work. But I will take look this weekend. If you can show the problem that you experiencing in a small example app, that would help a lot.
