    Default Deployment Error with Sensha SDK Tool - 'null' is not a constructor

    Deployment Error with Sensha SDK Tool - 'null' is not a constructor


    I'm trying to deploy my extJS-Application, which is written in MVC-Architecture style. As described in the extJS Docs I've first tried to generate a JSB3 File with
    Code:
    sencha create jsb -a index.html -p app.jsb3
    Sadly I've got the following error:
    HTML Code:
    undefined:0 TypeError: 'null' is not a constructor
    I'm working on MAC OS X with Sencha Command v1.2.2.

    My application works fine in the debug-mode. I have so many files that I couldn't insert all my source code here .. but of corse if someone can give me his assumption where this error occurs I will paste that part of my application..

    Thanks for any help!

    Default solved

    solved


    All right, I found the solution:
    For me, it was not clear that I've created a "...applications built on top of a dynamic server-side language like PHP..." (see doc).
    Deploy my app this way
    HTML Code:
    sencha create jsb -a http://localhost/path/to/my/local/index.html -p app.jsb3
    as described in the extjs-docs, everything works fine now..

    Great to hear, thanks for the feedback. Sounds like we need to do a better job making this more obvious so I've logged a ticket to improve the docs here

    I'm facing with the same error message. Unfortunately I already use the URL pointing to my server, so I do everything according to the documentation.
    Can someone please describe me what is this message would like to mean? Thx!

    The error quoted in the subject appeared when I was using IIS as the web server (WindowsXP). Now I moved to Tomcat, and I got a win32 exception. (Tried with both version 5.5 and 7)

    Default Have to leave out index.html

    Have to leave out index.html


    This is a top Google result so I wanted to add another detail for anyone else confused out there. I too got the "null is not a constructor" error when using the from-the-guide command, even though I am not using a dynamic language. The command is shown below:

    Code:
    sencha create jsb -a index.html -p app.jsb3
    To remedy, I did what the OP did (sort of) and used the actual URL, however, including "index.html" (as shown in the Getting Started guide) produces a new error:

    Code:
    sencha create jsb -a http://localhost/application_manager/index.html -p app.jsb3
    
    [ERROR] Ext is not defined, please verify that the library is loaded properly on the application's page
    undefined:0 ReferenceError: Can't find variable: Ext
    To get a complete working build, I excluded the index.html from the URL and this correctly created the .jsb3, which could then be built. The final command, then, was:

    Code:
    sencha create jsb -a http://localhost/account_manager/  -p app.jsb3
    Maybe I made a mistake somewhere being it was my first time using Ext JS, but I'm pretty sure I simply followed the guide. Hope this can help somebody else that was confused like I was.
