If I write
<form wicket:id="form" id="form>
or even
<form wicket:id="form>...
Then the rendered HTML shows the id ‘form’ appended with different numbers whenever the page is refreshed e.g.
<form id="form7"....
Is there a way to disable this behavior of the Wicket framework?
This is the behavior you want in most cases when using wicket. The dynamic id is meant to prevent id collisions when Ajax behaviors are added to components or added to ajax responses for refreshing. For any of these situations, you really need both the client response and the server side state to be in cahoots. If there are external js resources you need the id of a component for dom lookup, then I would suggest adding a custom wicket component behavior that would then generate the js call to a function passing in the generated id.
I realize what I’m going to describe leads you more into the forest of Wicket. But I have been more than happy with the ajaxy stuff that Wicket opens up for you out of the box.
