App not showing in Browser

**heloWelo** · 12 Aug 2012 12:14 AM

Hi All

First post here and VERY new to Sencha and Architect.

I've loaded an XML file into a List view and it previews the data correctly but when I try to preview the app in Chrome, I just get a small light blue rectangle in the browser. Nothing shows.

I'm guessing this some kind of deployment issue?

Anyway, would appreciate some pointers!

Thanks

Are you loading the xml from the same domain you are deploying the app to?

If not, you will want to ensure that you are...

See http://en.wikipedia.org/wiki/Same_origin_policy

If you open the developer tools, do you receive any errors?

Yes its in the same domain, just a quick test. The data shows up in Architect as expected.

I wasn't aware I needed to run the SDK tools when working in Archetect... have I missed something fundamental?!

I guess you meant Chrome Developer Tools? Oops

Can't see any obvious errors but this is my first use of these tools - diving into the shallow end!

You don't.

I was just making sure that it was being copied to the same place. If you are using a JSON proxy, you should also use a relative url and setup your URL Prefix as to where the project will be deployed.

I'm using an Ajax Proxy and everything works within Architect.

I've tried a new file with nothing but a button on it and still can't get anything in the brower. The standard(?) app.html is there when viewing the source code.

Is there a way for me to test my setup?

I suspect the XHR request is failing, open up the developer tools and see what is happening.

**heloWelo** · 13 Aug 2012 11:58 PM

Nothing showing for XHR.

Is this HTML correct for referencing the style sheets and Java scripts etc? I thought they might have to be deployed locally on a local server...

I've also discovered that once I have deployed for the first time, all subsequent saves and previews only view the original. e.g. Putting a button on, saving, deploying and then removing, saving and deploying, still shows the button...

We'll need more info about workflow, steps to reproduce, etc
