I have table of player in html: [table]
How I can hide or not render this table when it is empty? I try to add if conditional in java code and add this table to the page only if there is some value but then wicket throws an exception that he cant find component with this id. So how I can do this?
It throws the exception because the html markup expects the component to exist. Ie you must add it.
If it’s an entire panel you want to hide then using EmptyPanel is the will hide the entire panel.
You can also use component.setVisible(false) to hide it if its only one component in the panel.
