How to Trigger code in DNG.
Accepted answer
You can use the Javascript API to execute some javascript code as soon as one of the available events is triggered (ARTIFACT_SELECTED, ARTIFACT_OPENED, ARTIFACT_SAVED, ARTIFACT_CLOSED).
To use this API, you have to gain access to the Javascript RM Object - which first of all is available only in widgets.
Maybe there are also possibilities to access this object from outside widgets (e.g. in javascript code which you included using a Theme).
If you only use a widget, the user must first add it to the sidebar in order to activate your functionality.
You can find the Javascript API Documentation here:
In this topic:
I posted a short code example which executes some javascript as soon as a module is opened:
RM.Event.subscribe(RM.Event.ARTIFACT_OPENED, function(openedArtifact){
RM.Data.getAttributes(openedArtifact, [RM.Data.Attributes.FORMAT], function(result){
if(result.code != RM.OperationResult.OPERATION_OK)
console.error("Could not retrieve attributes of opened artifact!");
else if(result.data[0].values[RM.Data.Attributes.FORMAT] == RM.Data.Formats.MODULE)
console.debug("Module opened!"); }); });
Following this schema, this could be adapted in a way to be executed as soon as an artifact is saved.
You can then either implement your desired business logic directly in Javascript, or trigger some other code e.g. in a Server Application.

As far as I know you can not extend DNG to be able to do that, unfortunately.

Correct, you cannot extend or configure the web UI or server side code to do that.
What kind of functionality do have in mind?
Maybe I do not understand the question correctly, but what if you use a widget with some javascript which is executed when the ARTIFACT_SAVED lifecycle event is triggered (see section »Lifecycle events« in https://jazz.net/wiki/bin/view/Main/RMExtensionsAPI602 )?
You cannot prevent saving this way (because the event is triggered after the save operation), but I read the question like if some other functionality in addition to the save is demanded.
Yes Philipp,
I want to add additional functionality on save.
