Hi All, Ok, I will setup SVN, and give it a try.
Regards, Mark. -----Original Message----- From: Sandro Martini [mailto:sandro.mart...@gmail.com] Sent: Sunday, 26 January 2014 6:22 PM To: Users - Apache Pivot Subject: Re: How to Run Application without DesktopApplicationContext Hi all, Roger note that the additional version of main with an Application instance as argument exist already in DesktopApplicationContext (I put it with the changes for ...), take a look at: main(Application applicationInstance, String[] applicationArgs) which calls the usual version of main main(Class<? extends Application> applicationClass, String[] applicationArgs) As a sample (minimal) usage look at ApplicationWithPropertiesTest. So I think that all should already be in trunk, anyway tell us for other changes/improvements (that's the main reason for us to develop 2.1.x). For a non-GUI contric implementation of ApplicationContext, could be useful so if someone has an idea / some sample code we could try to look at it ... but in the meantime I hope that existing code in trunk (for 2.1.x) should be enough :-) . Tell us for suggestions, improvements, etc ... Bye, Sandro 2014/1/25 Roger and Beth Whitcomb <rogerandb...@rbwhitcomb.com>: > Hi Mark, > I have to apologize for confusing the issue.
