There is one big API change in Beta 1 that will affect all existing SWX applications that are running off the public SWX gateway on swxformat.org (http://swxformat.org/php/swx.php).
The arguments property for your data holder movie clips is now args. This change was made for two reasons: One, arguments is a reserved word and, although it doesn't clash with the built in arguments object (for method calls), I still didn't feel right using it. The second reason is to make it consistent with the new SWX full API in Beta 1. See this post for an example of the full API (note: I just updated that post to reflect this API change so it will be slightly different to how it was yesterday).
I will amend this post with an update once this is done. Please update your applications accordingly once the public gateway is upgraded.
This change (of course) will not affect any local development versions of the SWX gateway you may have until you upgrade to SWX Beta 1.
Update: I'm still updating all the sample apps (of which there are multiple versions to demonstrate usage without the api, with the minimal api and the full api) so this, along with the beta release, is going to be delayed to tomorrow).
Update: I've updated the gateway on swxformat.org to the Beta 1 version. Please implement the API change outlined above in your applications if you are hitting the public gateway here.
After changing to beta 1 i had too add ‘as required’ the since attribute with userTimeLine just to let you know, didn’t get through without the null given. (was working without ;))
Those error messages are great by the way thanks.
