Why not just put a conditional inside the wrapper around the

I want to allow subclasses, with the permissions working without
requiring a conditional

Hello, I'm trying to build a permission system that will disable
the contents of the entire component.
I guess normally I should override appendToResponse and disable the
writing of the component contents
there. But the problem is if I have a wrapper in the component I
still want to show the wrapper contents
so the wrapper will show everything apart from the
<wo:WOComponentContent />
The way I do it now is override the components template() method
and disable the elements that
should not be visible. My question is, is this the correct way of
doing it, and if so, are
there any hidden problems with doing it this way. The template
override code is this:
public WOElement template() {
WOElement tmpl = super.template();
if (!canViewComponent())
{
NSMutableArray<WOElement> children =
((WODynamicGroup)tmpl).childrenElements();
NSMutableArray<WOElement> removeElements = new
NSMutableArray<WOElement>();
for (WOElement el : children) {
if (el instanceof WOComponentReference) {
WODynamicGroup dg = (WODynamicGroup)
((WOComponentReference)el)._contentElement;
NSArray<WOElement> childrenElements =
dg.childrenElements();
if (childrenElements != null) {
/* this element is the wrapper,
only disable the
* content elements
*/
((WOComponentReference)el)._contentElement = null;
} else {
removeElements.add(el);
}
} else {
removeElements.add(el);
}
}
children.removeObjectsInArray(removeElements);
}
return tmpl;
}
