Seam GWT pageflow transition

由 北城余情 提交于 2020-01-05 05:11:07
问题 I am trying to integrate, Seam and GWT. I was wondering if can specify html pages in Seam page flow. Is it possible ? If yes what will the name in the tranisition stand for ? 回答1: We also use a combination of Seam page flow and GWT. Explicitly, we divide the login page from the main page to enable login via https. But, we do not use normal html pages, we still use xhtml pages. You can include a GWT html page within a Seam xhtml page by wrapping the <html></html> pair with a <f:view></f:view>

How do I listen to all Seam contextual events with parameterized names?

由 那年仲夏 提交于 2020-01-04 05:23:06
问题 Seam will fire different kinds of events that relate to particular scopes, tasks, or processes and appends the name of the scope, task or process to the end of the event. How do I listen to all the events of a type? E.g. for any <name> I'd like to listen to events such as these: org.jboss.seam.createProcess.<name> — called when the process is created org.jboss.seam.endProcess.<name> — called when the process ends org.jboss.seam.initProcess.<name> — called when the process is associated with

How does scope type affect the way an EntityQuery object is re-used

由 别来无恙 提交于 2020-01-04 02:34:11
问题 for (...) { UserList userList = (UserList) Component.getInstance(UserList.class, ScopeType.METHOD); userList.getUserByEmailAddress(emailId); } There are different ScopeTypes which are supported by Seam (e.g. METHOD, PAGE, EVENT, APPLICATION). We currently use the METHOD scope to retrieve User object by email id. The above code is present in a for loop (i.e. for a collection of user email addresses we retrieve the user object). Is this the right ScopeType or would it be preferable to move the

What is the 'official' SEAM way of listening to JSF-SEAM phases?

由 烈酒焚心 提交于 2020-01-01 16:26:37
问题 A simple question on the title. My case is that I want to listen to "before RENDER_RESPONSE" phase, and alter some components internal state. Is PhaseListener the "right way" to do this in SEAM applications? 回答1: If you want alter JSF component internal state, rely on JSF phase listener. Seam way of declaring JSF phase listener is shown bellow @Name("applicationPhaseListener") @Scope(ScopeType.APPLICATION) public class ApplicationPhaseListener { /** * Called TRANSPARENTLY by Seam */ @Observer
