Re: WebMarkupContainer without template markup
We're choosing an item from a list and then using ajax to populate a
view of the item, together with a listview of purchasable details.
For any given item there may or may not be images. Either managing
the relevant components in a page-level collection or using a visitor
to find them works. The key to the solution is:
1. they are all in a panel
2. that panel must be an ajax target
3. the logic to determine whether they are visible must be in the
onbeforereneder method of that panel
Thanks all.

This is less centralized that keeping a list at the top level, if you

Damn. I just now recommended the same thing. Sorry, didn't notice
your post.
This approach definitely seems cleaner than managing a list of
component references -- I wonder if it works for Scott...

Re: WebMarkupContainer without template markup
How about using an IVisitor to call setVisible() on the image
components? That way, you wouldn't need to keep an explicit reference
to those image components. You could trigger the visitor in
onBeforeRender() and you could use a marker interface to identify the
image components whose visibility should be changed (called
'IOptionalImage' in the example below). Something like:
public class OptionalImageVisitor implements IVisitor {
private boolean visible;
public OptionalImageVisitor(boolean visible) {
this.visible = visible;
}
public Object component(Component component) {
component.setVisible(this.visible);
}
}
public class MyPage {
public onBeforeRender() {
boolean imagesVisible = ...logic to determine whether images are
visible
visitChildren(IOptionalImage.class, new OptionalImageVisitor
(imagesVisible);
}
}

Matej,
My issue isn't that the div is rendered, but rather that I have to add
it to the html file in the first place. I think that I could
implement this as a Behavior, but for this problem I just went ahead
and added div tags around the relevant components.
Thanks again,

The basic problem is that sometimes we have a set of images for a
product (scattered across a few components) and sometimes we
don't.
My thought is to wrap all of the relevant images in such a
container
that knows how to determine isVisible().
