XPages Event parameters solution found

It's very interesting that event parameters retrieval is totally undocumented and there is no articles / blogentries about it on the web. You should know that I have been searching and trying to get the solution thru the community but with no luck.

But Now I have found the solution

When triggering a onClick event the this object will contain a XspEventHandler and
this object has a method called getParameters() this method will return a Java ArrayList.
The arraylist will contain the parameters with name and value.
So to print all parameters you can walk thru them like this

var value=this.getParameters();
var tmp="";
for(x=0;x<value.size();x++){
tmp+=value.get(x).getName()+" - "+value.get(x).getValue();
}

tmp will then contain a string will all the names and data of the event parameters for you to display.

Check out my article in the application development wiki

  1. Hm...I tried to retrive the parameters in a computedField, but then I got:

    Script interpreter error, line=1, col=16: Unknown member 'getParameters' in Java class 'com.ibm.xsp.component.xp.XspOutputText'

    is this a client or server code?
    is event parameter used instead of scope, or why should this be used?

    there is also a SSJS global event called param, eg. param.get("name") but that does not seem to work in this context.

  2. It's available there computer field don't have any events, the only place I have tried to use this is with links.
    And in that case you could also use just the name of the event paramenter.
