User Macro getGroup

[Rene Hegewald]

I want to list users of a group, but if the group not exists, i get an error

## Users Pictures for Group - Confluence User Macro
##
##   Produces a pile of user profile pictures for members of a specific group
##
## WARNING:
##
##   Use very sparingly as this *will* slow down large Confluence instances.
##   Yes, it will try to print out 100,000 users if you have that many in the group
##
##   I generally remove this user macro after using once and add only when needed.
##   Or enable it for admins only.
##
## @param Group:title=Group Name|type=string|required=true|desc=The group name (yes, really)

 
#set($containerManagerClass = $action.class.forName('com.atlassian.spring.container.ContainerManager'))
#set($getInstanceMethod = $containerManagerClass.getDeclaredMethod('getInstance',null))
#set($containerManager = $getInstanceMethod.invoke(null,null))
#set($containerContext = $containerManager.containerContext)
 
#set($userAccessor = $containerManager.containerContext.getComponent('userAccessor'))
#set($groupManager = $containerManager.containerContext.getComponent("groupManager"))
#set($group = $groupManager.getGroup($paramGroup))
#set($users = $userAccessor.getMemberNamesAsList($group) )
#set($komma="")
#foreach( $username in $users )
    #if ( $username != "service" )
       $komma 
       #usernameLink($username)
    #end
    #set ($komma=",")
#end

is there a way to catch this erorr and wrote a message "Unknown group" ?

Hi! 

Looks like getMemberNamesAsList gets so slow. 

Because I have met the same situation in my plugin .

Have you fix it?
