allow accounts[0] to be undefined

[dkent600]

Allow accounts[0] to be undefined. Issue a logged warning instead of throwing an exception.

This allows for cases where arc.js is used in read-only situations.

When undefined, don't set a default user in Utils.requireContract.

A possible related feature would be to provide some means of reinitializing WrapperService when the default user account changes.

So then Alchemy would have to check if the default account exists or not?

[tibetsprague]

would love to have arc.js auto detect account changes

Yes, the application (Alchemy) would need to check if the default account exists. No more exception in that case.

I will create a new ticket on creating a Pub/Sub event for when the account changes.

When the user finally sets the default account, the application will have to re-invoke InitializeArcJs. You can use the existing Arc.js subsystem for watching for account changes.
