JSF ViewParam Required +AJAX breaks page

由 巧了我就是萌 提交于 2019-11-29 21:12:12
问题 When I click the command button on the page below navigations fails. (Clicking on the button refreshes the page, removes the URL parameter and displays the required error message instead of navigating to the index page) However if I remove the required attribute OR I remove the f:ajax tag the navigation works fine.

JSF bean: call @PostConstruct function after ViewParam is set

由 匆匆过客 提交于 2019-11-29 01:56:41
I have a product.xhtml and a ProductBean. I use /product/{id} to access the products so I have a viewParam in product.xhtml with value=ProductBean.id. The problem is that inside the bean I use an init function with a PostConstruct annotation in order to fill the details of the product. To do this I need the id to call an external function. I guess though that init is called before viewParam sets the id of the bean and therefore inside init I cannot call the external function because id is not set yet. What am I doing wrong and how do I fix this? UPDATE I found what was wrong. I think the

View-scoped bean recreated on POST when URL parameters not used

I have a view-scoped JSF-managed bean that's backing an xhtml view where I read one parameter from the URL using f:viewParam . The view presents a form to the user. However, when the user submits the form by pressing the p:commandButton it seems that the view-scoped bean is recreated (I added a @PostConstruct annotation to verify this) and so doesn't remember the instance variable read from the f:viewParam ( invId in the code below). I originally navigate to the view with a GET that includes a URL parameter but the POST message that's send when the user presses the p:commandButton doesn't
