Hi all,
One of the difficulties I am finding with wicket is the best practice
when displaying/using data that is potentially null.
Example:
I have a "user" object which has a nullable "group" property. I want to
show a link to the group details page when the "group" property is not
null, but show nothing otherwise (let's keep this simple).
My issue is that either way, I have to construct the link component and
add it to the page, whether I want it is visible or not. This is tricky
at the best of times, as I must always carry out a lot of "is null" logic.
The construction issue becomes multiplied if I want the same behaviour
on a stateful page (i.e. the link, etc. can be appropriate for linking
to the group, or be null and not visible and can switch between the two
states).
My question is - am I missing something, or do I just need to have a
better strategy for this type of situation?
If the answer is the latter, does anyone have any tips and/or components
that would cut down on the extra coding?
Thanks
