Is it possible to have some code run as soon as a wizard page is displayed?

I'm trying to accomplish the following: On the first page of a wizard, query
parameters are collected. When the user advances to the next page, the query
should be run automatically, and the results should be displayed for further
selection.

Eric,
Yes.
getNextPage() method should return the next wizard page that would be
displayed when next button is pressed. (Should return null if the user did
not specify all the required attributes for the current page i.e. next
button would be disabled). After collecting all the information in the
current page, perform the query and pass in the value to the next page.

You can also use this to skip pages in the wizard, for instance

Thanks for the tip. In any case, it works, though having functionality such
as running queries being called from a method with the name 'getNextPage'
doesn't make the code any less confusing... Having methods that are called
whenever a page is entered or left would be a much nicer solution, in my
opinion.

You prefer this? You are called with getNextPage(), then you return a page,
then you are called again that the page you just returned has been entered.

The idea is that wizard pages are chained, but you control what page
is shown next, allowing you full control over the page continuation process.
Seems overkill to send you page enter/leave events in this case?

My point of view: I have code that needs to be run when the page is loaded,
and apparently the only solution is to put it into a method called
'getNextPage'. Seems strange to me...

Just a design tradeoff. Your case was apparently decided to be of secondary
importance :-)
