I have a list view that will have a button on the left to expand or contract
a section that starts out hidden. this section will have some additional
details. Code and HTML below.
When I click the button, the event arrives in my onActivityLogExpansion, and
the wicket ajax debug control turns red. The log says the following, that I
did not setOutputMarkupdId to true. But I did as you can see in the code.
INFO: focus set on ui-id-3
INFO: focus removed from ui-id-3

component.setOutputMarkupId(true) on the component whose markup you are
trying to update.
