How to get all the children of a MarkupContainer?
Use iterator(Comparator)?
Or other ways?
Thanks,
Valentine

Re: How to get all the children of a MarkupContainer?
Posted by Valentine2008 <va...@alumni.sfu.ca>.
Hi Igor,
I find it out!
The reason I couldn't get a child using a string component path is because
of the outdated JavaDoc sentences in MarkupContainer (Wicket 1.3.4):
"....Children can be added by calling the add() method, and they can be
looked
up using a dotted path. For example, if a container called "a" held a nested
container "b" which
held a nested component "c", then a.get("b.c") would return the Component
with id "c". ....."
It said about *dotted* path with a clear example. And I used the dotted
path.
Now I find that the Component.PATH_SEPARATOR is used, which is ":".
We have to use a.get(b:c") in the example.
Can we confirm that the JavaDoc is updated in the next coming release of
Wicket?
Thanks,
Valentine

no. why would it do that? visibility is a render-time condition, it
has nothing to do with component hierarchy.

But Component.get(pathString) will check the visibility and will return null
if the child is invisible. Right?
