LC Web integration is not good enough

The problem is that no web api expects an object with numeric keys, it
expects an honest, real, array. The fact that LC arrays are actually
hashmaps is awesome, I love them as well, but it still makes it impossible
to export arrays from LC which are really common on Web APIs. JSONExport
library should check if the keys of a given array level are all numeric and
cast it to a list type.
Thats is what I say when RunRev web integration is not good enough. They
provide a json import and export function but it doesn't work well enough
for you to call any API that expects an array... We always go like 70% or
80% of the way in a feature and then there is a new LC Infinite Ultra
Campaign to get some new stuff in when the current stuff is not yet ready.
Same thing with executing JS inside a WebView Widget, we need to use the
"do in widget" statement but this doesn't have a way to bind values, so you
end up assembling a JS string by hand in hopes that you got all the correct
quotes right because you need to inline all params as literal objects...
