remote provided slot not resolved for particle in a separate recipe

[mariakleiner]

arcs-hello-world
If splitting the particles to separate recipes:
recipe
Greet
recipe
PersonalGreet

where
particle Greet
consume root
provide personalGreeting
particle PersonalGreet
consume personalGreeting

after Greet was instantiated, a slot should become available for Personal Greet, but it is not getting resolved by the map-remote-slots strategy.

this is due to the playground demo only calling the Planner to generate suggestions once.

ui.callback = () => {};

the suggestion-element callback needs to be set to smth that triggers Planner.suggest, similar to the demo-base.js nextStage() method.

In Arcs CDN v0.03 I implemented regenerating suggestions. Please try it out.

Thanks, I tested it with the hello-world and chat glitch apps, and it works fine.

In the hello-world glitch (https://glitch.com/edit/#!/arcs-hello-world) after choosing 'Hello' I expect 'Greetings to you' to become a suggestion, as per the discussion in this ticket.

I guess it's what I expected to work as per "tested it with the hello-world glitch app".

I must have the wrong expectation, can you explain?

[mariakleiner]

in https://arcs-hello-world.glitch.me/
at first I get 2 suggestions:
"Hello and Greetings to you"
"Hello"

after I choose "Hello", I get 4 suggestions, one of which is "Greetings to you".
Is it not what you're getting?

Sigh. Originally the toast was supposed to open again when there are fresh suggestions, this is the bug in my expectation: because the toast didn't open I assumed there were no suggestions.

A thousand pardons.

I actually thought it was a feature, because the demo always behaved like this (I think) - it makes perfect sense to me, when user already has their content on the screen, it might be better for suggestions not to pop up.

At one point I went to special pains to allow the apps to control this behavior (I think I wanted something different in the VR demo). At any rate, this is ancient history.

After I realized my gaffe, I came to the same conclusion you did (that it's better not to pop-up new stuff until the user asks for it).

Thanks for the help!
