+ | =====Session sharing====== | ||
+ | Client logon with (patientid, template) tupple.\\ | ||
+ | Server makes lookup in active sessions for tupples matching the one supplied by the client.\\ | ||
+ | If none matches, a new session is created and ' | ||
+ | If a match exists, the client is queried if it want to take over the session.\\ | ||
+ | The session state is to be stored with the session (open, closed_no_commit) so the client must actively notify the server when a session is closed without commit.\\ | ||
+ | If a client is about to take over an active (not closed_no_committed) a warning should be issued, about possible race conditions happening. | ||

+ | ====The Script Tag==== | ||
+ | The script tag can either consist of inline code, or be a reference to a serverside file, that will be inserted in-place by the server before it is sent to the client. | ||
+ | <code xml> | ||
+ | < | ||
+ | <script src=" | ||
+ | < | ||
+ | --example | ||
+ | </ | ||
+ | </ | ||
</ | </ | ||
+ | ====The Widget Events==== | ||
+ | Each widget has an event that is inspired by the current '' | ||
+ | Currently the script is referred by its name, and called whenever the widget changes its value.\\ | ||
+ | In the new system, the script attribute is removed and replaced by event attributes. The event attributes will themselves contain lua code and not simply a name. In order to call ' | ||
+ | The return values will no longer be used. Instead widget methods will be added to control the validation state of each widget, eg. '' | ||
+ | Since it is no longer required (due to redundancy) the '' | ||
+ | |||
+ | ====Event Handlers==== | ||
+ | * '' | ||
+ | * more to come | ||
+ | |||
+ | |||
+ | |||
+ | ====The Widget Object==== | ||
+ | When in a lua function, invoked by an event handler, the calling object (the object invoking the event) will be made available through the value ' | ||
+ | Other object can be retrieved using the '' | ||
+ | <code lua> | ||
+ | function foo() | ||
+ | if (this: | ||
+ | then | ||
+ | this: | ||

+ | |||
+ | bas = widget(' | ||
+ | if (bas && bas:value() == ' | ||
