Ext TreePanel in AIR application [Solved]

[RobSmith]

I want to use a TreePanel in my first AIR application and get an error regarding security reasons of using eval() in AIR application sandbox. So I took a look at the sample application written by Jack himself (simple task). When I looked up the code I realized that he rather extended the TreePanel class instead of just instancing.

Does anybody can explain why? Is it because of the security issue of AIR I mentioned before?

Thanks in advance

Rob

Addition:

The error occurs when I am hovering the TreePanel. This is, what the log says:

Error: Adobe AIR runtime security violation for JavaScript code in the application security sandbox (eval)

Seems as I left my brain at home today. I hate mondays. The solution is quite simple, I forgot to implement the Ext/air javascript.

Sorry guys to bothered you.

Hi Rob smith, I encountered the same problem, it seems that the eval() is not allowed in AIR. What do you mean by implementing Ext/Air? Did you import other libraries or change certain lines in ext-all.js? Thanks

[RobSmith]

Sorry for the late answer. What I mean was to include the tag

<script type="text/javascript" src="..../ext-air.js"></script>

to your html file. That was what I forgot to do. Hope this helps in your case too.
