The security section seems to be slightly sketchy when deleting groups.

One problem I have noticed is when you select to delete a group what contains child groups, if you DON'T highlight each child group (select the checkbox so the group becomes a solid colour, rather than a light gray), the group will not be deleted from the database.

I've modified the javascript slightly so when a parent group is selected, ALL children are now automatically highlighted and assigned a delete action.

If anyone else has had this problem, feel free to use the code below as a workaround (its been tested for one branch but no more).

1. Open cms\javascript\SecurityAdmin_left.js

2. Go to the deletegroup object and insert the following lines below the if(sel && sel.className.indexOf('nodelete') == -1) { } block:

// NEW: Added to highlight child groups automatically
var children = sel.getElementsByTagName('li');
for(var i=0; i<children.length; i++)
{
var selIdx = $('sitetree').getIdxOf(children);
deletegroup.selectedNodes[selIdx] = true;
children.addNodeClass('selected');
}

This will basically highlight the child groups and assign the delete group method so the groups are deleted properly.

This issue also seems to affect users within the groups (if a group contains users, they are removed from the security section but still exist in the members table?!).

If i determine a quick fix for this I'll post it up.
