AlfrescoJavaScript: global script variables

[blackout]

Good day everyone!

I have been reading Alfresco's source code for some time, till I got to the createInputMap method in AlfrescoJavaScript.java file.
Inside that method I read that global variables like userhome and person are mapped into a Java HashMap, so that they're disposable for all scripts (depending on context).

Is there a way to have more global variables without modifying that file? Something like mycompanyhome or companyhomeRome, companyhomeFlorence and so on…

Thanks in advance

Yes.

Take a look at script-services-context.xml.

It demonstrates how to inject new root variables into script.

lol, flashreply ftw!

Thanks man

I have another question about search APIs: can you tell me examples of XPatch search (by using xpathSearch(String search)), Lucene search (by using luceneSearch(String search)) and normal search (by using findNode(String ref)) to find an hypothetical "Test Space", son of the default space "Company Home"?

I have to get that noderef in order to build a folder tree inside it.

Thanks

I tried this script:

var testFolder = search.findNode("workspace://SpacesStore/c88cbacf-b208-11db-b111-6108c46f71e5");var prjFolder = testFolder.createFolder("Folder di Prova");prjFolder = prjFolder.childByNamePath("Folder di Prova");prjFolder.createFolder("Documenti di gara");prjFolder.createfolder("Offerta tecnico economica");‍‍‍‍‍

But is not working:
