Hello,
I've defined an abstract subclass of WebPage (BasePage) that knows
whether or not a user can access the content of any concrete page. If
a user does not have access, I don't want to block them from landing
on the page; instead, I'd like to show some page-specific content
instructing them how they can gain access to it. The structure of
that content is the same across all of my pages, so I'd like BasePage
to a) define the markup necessary to display it, and b) hide its
subclass's content when necessary. I came up with the following
approach, defining childContent as a transparent resolver:
BasePage.html
...
<div wicket:id="childContent">
<wicket:child />
</div>
...
BasePage.java
...
WebMarkupContainer childContent = new WebMarkupContainer("childContent") {
@Override
public boolean isTransparentResolver() {
return true;
}
};
childContent.setVisible(isAccessible);
add(childContent);
...
Although this works, I have run into problems related to the
transparent resolver (e.g.
http://wicket-users.markmail.org/search/?q=#query:+page:1+mid:3gmjcjrggaxdrek2+state:results).
The only other approach I can think of is to add code to each
BasePage subclass that will hide its components when isAccessible is
false, but that seems fairly redundant. Any other ideas? Aside from
defining a transparent resolver (not recommended, and apparently
removed in 1.5), is there a design flaw to this approach?
I'm using Wicket 1.4.18.
Thanks for your help!
