• Flex - Cancel drag operation via keyboard

  - by Tom

  Hello I would like to be able to cancel a drag operation with the Escape key. The following did not work so far: calling stopDrag() on the component -- nothing happens calling DragManager.acceptDragDrop(null) -- nothing happens calling mx_internal function DragManager.endDrag() -- drag partly stops, the drag proxy image disappears but now the drop indicator shows at row 0, and also there's a null error when finally releasing the mouse Anybody else had any luck with this? Thanks!

• Implementing a scalable and high-performing web app

  - by Christopher McCann

  I have asked a few questions on here before about various things relating to this but this is more of a consolidation question as I would like to check I have got the gist of everything. I am in the middle of developing a social media web app and although I have a lot of experience coding in Java and in PHP I am trying things a bit different this time. I have modularised each component of the application. So for example one component of the application allows users to private message each other and I have split this off into its own private messaging service. I have also created a user data service the purpose of which is to return data about the user for example their name, address, age etc etc from the database. Their is also another service, the friends service, which will work off the neo4j database to create a social graph. My reason for doing all this is to allow me up to update seperate modules when I need to - so while they mostly all run off MySQL right now I could move one to Cassandra later if I thought it approriate. The actual code of the web app is really just used for the final construction. The modules behind it dont really follow any strict REST or SOAP protocol. Basically each method on our API is turned into a PHP procedural script. This then may make calls to other back-end code which tends to be OO. The web app makes CURL requests to these pages and POSTs data to them or GETs data from them. These pages then return JSON where data is required. I'm still a little mixed up about how I actually identify which user is logged in at that moment. Do I just use sessions for that? Like if we called the get-messages.php script which equates to the getMessages() method for that user - returning all the private messages for that user - how would the back-end code know which user it is as posting the users ID to the script would not be secure. Anyone could do that and get all the messages. So I thought I would use sessions for it. Am I correct on this? Can anyone spot any other problems with what I am doing here? Thanks

• Jetspeed 2.2 Nest or render one portlet inside another

  I have a requirement to build an extensible wizard in a portlet. This wizard will list components that are installed and forward the user to a sub-wizard that is component specific. The requirement is that the components are to be developed by other people and dynamically plugged into this wizard (Jetspeed reboot is okay).
