View Full Version : Problem with Viewport - not a constructor

21 Apr 2010, 11:03 AM

I've created a simple project which works fine in the designer. Run it from a browser and I get the following error:

Error: ppViewPort is not a constructor
Source File: http://admin.peachpublishing.co.uk/ed/xds_index.js
Line: 15

Here's the URL of this project.


I've also attached the ExtDesigner project.

Any ideas why I'm getting this error?

It appears there is a bug in the Designer where assigning a jsClass name where the first character is lowercase results in an error. This is because the var reference name that gets used in one of the .js files then happens to be the name of the class - name collision!

I'd file a bug report on this. However, best practice oo programming is usually to begin a class name with an uppercase character, anyway.

Change your jsClass on the ViewPort to have an uppercase first character - like MyViewPort or something - and you should be fine.

Hey thanks for the solution, I was having the same problem. Should be fixed.
