Which is the best way to manage the visibility of a component?
Hi, I'm using wicket 1.5.7 and I have the following scenario. A page with two DropDownChoice that we will call A and B. Values of B depend on value of A and are updated by Ajax. Then a WebMarkupContainer component that we will call C. The visibility of C depends on value of B. I added in the method onUpdate of AjaxFormComponentUpdatingBehavior(onchange) of B some statements to check the value of B and set the visibility of C accordingly. But it's triggered only when the user change the value of B. That value can be changed by ajax when the user change the value of A. So, which is the best practice to deal with this kind of problem? I have to add the same code in the AjaxFormComponentUpdatingBehavior(onchange) of A too? Is there a better solution avoiding duplication of code?

You can write the code in a separate method and call that method from A and B... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Which-is-the-best-way-to-manage-the-visibility-of-a-component-tp4650853p4650854.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

You could override C's onConfigure() to set its visibility based on B, and override C's onEvent() to add C to the ART if it's current visibility is wrong. https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-Defaultajaxevent On Sun, Jul 29, 2012 at 6:17 AM, Alberto abros...@ogs.trieste.it wrote: Hi, I'm using wicket 1.5.7 and I have the following scenario.
