Wrong selected option for selectOneMenu with POJOs and Converter

由 牧云@^-^@ 提交于 2019-12-13 09:25:52
问题 in our company we're hitting a serious problem which we think is a serious design flaw of the JSF spec, if it is the normal behavior. This is our usecase: SelectOneMenu (standard JSF or primefaces, doesn't matter, same behavior) SelectItems with a database entity as it's value and a string as the label A converter (via attribute on the selectOneMenu) which translates the entity to its ID (getAsString) and from the ID to the entity (getAsObject) Everything works as expected as long as the

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . It seems to me that p:inputText does not support sending parameters via f:param . Is this true? If yes, how could I pass the parameters? In more details I have a list of inputText fields generated via: <p

Transfer and trigger javascript code by ajax call with jsf

由 戏子无情 提交于 2019-12-13 07:37:58
问题 I have some jsf-code with a tag that is re-rendered by an ajax call. It contains something like <h:outputScript>alert("Gotcha")</h:outputScript> but this is only executed on first load, not on an ajax induced partial render. This is but a minimal example, what I'm really trying to do is to trigger some server-generated javascript right after the ajax-call has returned, something like <h:outputScript>#{scriptBean.getScript()}</h:outputScript> I've seen calling .trigger("click") that is in

Primefaces 5 <p: calendar> does not display the option to select time

由 前提是你 提交于 2019-12-13 07:35:12
问题 Need to use the component p:calendar with the option to select the date and time (hours, minutes and seconds). The problem is that the option to select the time is not displayed, only the option to select the date. I am using the following pattern "dd/MM/yyyy HH:mm:ss". According to primefaces showcase no additional attribute is required for display of schedule options, only define the pattern. <p:calendar pattern="dd/MM/yyyy HH:mm:ss" value="#{calendarMB.date}" timeZone="GMT-3" /> Managed

How to add JS effects on rendering AJAX parts in JSF2?

由 旧时模样 提交于 2019-12-13 06:55:54
问题 In JSF2, I can update part of view by AJAX. I assume part of components tree is just generated/updated on server, rendered to HTML and this HTML is sent to client. Then inserted into DOM where appropriate. This works, but I wonder if I could add some jQuery (or other JS) effect when I want this new HTML part to appear? What if I want it e.g. to fade in? Can I do this? How? 回答1: It's easy if you use Primefaces: http://www.primefaces.org/showcase/ui/effects.jsf Otherwise you could use the
