Using Http and .json() - unexpected result.

[matt4446]

I've taken a look at the previous issue taking me to here
, but seems unrelated.

Im expecting an Array from .json() but I cant iterate over it, or get the length.

Testing in Android...
My current code

The call is correct.
.Text() has the expected outcome.
.JSON() appears to work - but i cant get any data from it.
Expected: Array (well Array)

Its working correctly in a ionic2 application link.

Here is the Logging for that view:

I've included your json passed log line. Any thoughts?

best regards,
Matt

Hi @matt4446

That turned out to be caused by a bug in our XMLHttpRequest implementation. I fixed it, and published a small sample repo that contains both a web and a mobile project that uses the Http service to read JSON data.

You could test it in your app by changing your tns-core-modules dependency to 1.6.0-angular-2.

Perfect.
Thanks.

@hdeshev I'm still having trouble with this (android). Shouldn't this now be part of 1.6?

package.json

"tns-core-modules": "^1.6.0"

I've tried switching to 1.6.0-angular-2 on my main project, but the response still does not deserialize into an array there either.

Pretty much the same code again

items.forEach fails as well.

@matt4446 My code here looks almost the same, and it works. The only difference is that I just tried it with tns-core-modules@1.6.0. Could you try upgrading to that version? I also upgraded the project to the latest angular renderer and Angular beta-6.

thanks @hdeshev
I'm preparing for a competition this evening from Friday -> Sunday evening after work so may not have time to check till Monday with a day off (will try this evening).

So change the package.json?
your demo package file:

my package file:

Am i missing something simple?
npm install has been run a number of times against the different versions.

I made the upgrade to 1.6 yesterday and now have several other things working like the Array.create on the animation. Some other things have changes like the border element disapearing on the view ...
but I'm focusing on this at the moment.
