On the same note, I also have the following questions: The answers will help implement whichever option we choose:
1) Is there a limit on the number of members that can belong to a group?
No. Well, there's the practical limit of how large Java lists can get and how much memory the JVM has, but there's no special limit set in the XWiki core.
2) How can I create a "global" hashmap (xwiki.getHashMap()) that can be referenced anywhere (any page/space) to retrieve values based on keys?
You can't. That's what the XWiki objects are for, to give you persistence. Theoretically you can create a HashMap and put it in the application context, but that will disappear when you restart the server, and it requires programming rights.
3) Can I use the $context to add some more values(needed for our project) to the hashtable?
Yes; note that it requires programming rights.
4) I came across the following code snippet int he Wiki editor of the PanelWizard: #set($categoryMap = $xwiki.getHashMap()) #foreach($category in $categoryList) $!categoryMap.put($category, $xwiki.getArrayList()) #end
I do not understand the use of "!" in the put() method. what do we achieve with this!
Standard Velocity syntax, it means that a null output will not print the code. By default, when some script doesn't return a string, it will be printed literally, and ! prohibits this. If it wouldn't be there, the rendered page would literally display several $categoryMap.put... texts. -- Sergiu Dumitriu http://purl.org/net/sergiu/
