Undifined Index on Checkout, Magento 2.0.4

[grasdaggel]

We've installed your module on a Magento 2.0.4 system. When we're trying to access the checkout we get an error:

@grasdaggel do you have a hosted iFrame styling configuration in the database? What does

SELECT value FROM core_config_data WHERE path = "payone_general/creditcard/cc_template"

return?

Thanks,
Florian

It returns nothing. That said, we didn't modified the modules settings because we just wanted to have it installed in the shop.

The module shouldn't break anything when not configured or configured in a wrong manner.

[fjbender]

@grasdaggel agreed.
@Fatchip-Support Aren't we shipping some kind of default data, so that the array is always populated? Otherwise we should check if there is data before populating the array to avoid issues like this.

[grasdaggel]

If you need anything else from me, just give me a shot. I will deinstall the module for now, but I can reinstall it real quick. Thanks for your help.

Should be fixed with b5a990c.
