Clearing form fields after invalidation JSF - jsf-2

Ok i have the following problem: In my web app i have the CRUD all one page via dialogs controls of Primefaces. In the new dialog i have some validators. For example: when a user does not fill the necessary fields for form submission obviously the form doesn't submit. But when i close de New dialog and open it up again, the validation messages are still there! How can i get rid of this? I want a fresh new page (without accumulated validation errors) every time a dialogs open up! How that can be done?

The panelgrid inside a outputpanel or tabview has the components more smaller that the others panelgrid that are outside. I'm working with PF 4.0 and JSF 2.2
Thanks for all
Seems like this is because it scales based on width. In tabview width of panelgrid is much smaller, than outside.
In this case, I would suggest to create css styles for each component and apply them, rather then making them stretch automatically

preRenderView-Event triggered before an action

With the JSF Lifecycle in mind, it is not really possible to have an preRenderView-Event being triggered before the "Invoke application" phase is finished. Please double-check the following:
Is the action invoked at all? In case of an converter/validation error the "invoke action" phase is skipped and the response is rendered instantly.
Are you calling the method from somewhere else? saisieDevisController.init sounds pretty generic. Maybe a trigger like #PostConstruct calls it earlier (nested).
Hope it helps...

Problems with control of primefaces components by Managed Bean

I hope somebody could help me with the trouble I am having with JSF 2 and Primefaces 3.0M3.
the problem is that the back bean methods do not fired from any component in the layoutunit 'center' they are inside a form and nothing happens, even I tried to update the components with remoteCommand, autoUpdate of the outputpanel, commandButton with action and actionListener and nothing, there is no error message. In the layoutunit west works the components well, renders the outputpanel (pfpInfo) of the center layoutunit but I do not know what is happening.
here is the code

GET Parameter View Scoped Bean

I have a strange effect on my JSF2/richfaces 4 project. I use a viewscoped bean and a datascroller to view some data from my backing bean. The bean is viewscoped and to pass the figureId parameter I fire the preRenderView event.
<f:metadata>
<f:viewParam name="figureId" value="#{pointEdit.figureId}" >
<f:convertNumber pattern="###" />
</f:viewParam>
<f:event type="preRenderView" listener="#{pointEdit.init}" />
</f:metadata>
Displays fine, but when I click on the second site of the datascroller I get a nullponter exception for this line: <f:event type="preRenderView" listener="#{pointEdit.init}" />.

My Bean:
#ManagedBean
#ViewScoped
public class PointEdit implements Serializable {
public void init() {
FigureService figureService = Utils.getSpringBean(FigureService.class);
figure = figureService .getById(figureId); // figureId will NOT be passed from GET
pointListToDisplay = figure.getPoints(); // nullpointer :-(
Before I imported my new data it worked fine on my test figures.
Why is my figureId GET Parameter not found in the init function? With my testdata (5 figures) I never had a problem with this.

You need to either pass that parameter as <f:param> in the command link so that it retains in the subsequent request:
<h:commandLink>
<f:param name="figureId" value="#{pointEdit.figureId}" />
</h:commandLink>
or to check in the init() if FacesContext#isPostback() equals to false before proceeding (so that it only runs on a fresh new GET request, not in the subsequent postbacks as the bean is view scoped and the properties are already been set anyway):
public void init() {
if (!FacesContext.getCurrentInstance().isPostback()) {
// ...
}
}
My new test images where 5 times larger then the images i got 4 testing. In my ViewScoped bean i had the figure as property so the whole byte[] had to be serialized.
After removing this design flaw it works again and also explains why the new images cause troubles!
