Basically what happen: * when you view the page: a java listener is created and registered in groovy and your velocity is executed but onEvent is not called * when an event is received: onEvent of previously registred java object is called and nothing else, the script is not executed
So if you need to do something when an event is received you need to do it fully in the onEvent method.
Thanks Thomas! As I understand, I should include all my planned script actions inside groovy script (same as groovy script make changes in a title of source page)... According to this, I have another question. I should include ALL my actions inside this onEvent object? For example, can I have on another page something like macros (like velocity macros) and everytime, when I need (when onEvent is called) - call this macros from onEvent object and execute this? This is can be helpful if I need to repeat (when onEvent received) some actions (for example - change title not only for source page, but for all pages of a some class). If I can - it is possible to call velocity macros, or all like this procedures should be written on groovy?
There is some possible hack to call velocity script from groovy but would be a lot easier to do pure groovy actually. If you want to repeat a task you should add a groovy method, for example onEvent itself is a method you can call it with parameters and it also can return an object which is a lot better that wiki macro in this context. Wiki macro are really targeting display and are really not supposed to be use as methods. To summarize: yes I think you will have to do learn some groovy and after some time you will see that it's a lot better than velocity for a use case like that where you don't have anything to display. You can take a look at http://groovy.codehaus.org/Beginners+Tutorial which seems pretty nice. You should get started pretty quickly, groovy is really easy for someone who already did programming in any other language.
