Hey all, I'm currently in the progress of migrating a largish Wicket 1.5 app to Wicket 6.2. The only major problem I could not resolve so far are precondition scripts with user input.
My old code looked like this: @Override > public CharSequence postDecorateScript(Component component, CharSequence > script) { > return "jConfirm(function(r) { if (r) {" + script + "}});"; > } The whole script was decorated and the callback only executed if the user pressed OK in a custom confirmation dialog. In Wicket 6, there are no more script decorators, just listeners that provide hooks into the ajax lifecycle, so I changed my code to this: @Override > public CharSequence getPrecondition(final Component component) { > return "jConfirm(function(r) { if (r) { return true; } }); return false;"; > } The problem is, that the callback function I'm passing to jConfirm is evaluated only when the user makes a selection, but the precondition has to return an output immediately. It would work if we used browser-level confirmation dialogs, but we use a custom jquery dialog for better user experience. Is there any way to emulate the pre-Wicket 6 behavior using listeners? Kind regards, Thomas
