HI,
im using this tag this way:
h:outputText value=#{date.start}
f:convertDateTime pattern=MMM /
/h:outputText
So my date.start is in Database saved as September 2007, but outputText show
me August 2007. If I convert days also, it will decrease my days by 1 and
not the month.
Im using MyFaces 1.1.5 with Tomahawk 1.1.5 and Facelets 1.1.11
Thx. i. A.
Daniel
Re: DataTable + Check Buttons
hello daniel, i read, that you are using tomahawk and that you found a solution for your problem. however, i would like to give you or maybe some others a useful hint: if you decide to use myfaces-trinidad there is a nice way to solve your problem without affecting your data. the trinidad table supports single and multiple row selection (and a lot of other features): you will find a selection-demo at: http://www.irian.at/trinidad-demo/faces/components/table_selection.jspx (on top of the page you can switch between single and multiple selection.) regards, gerhard 2007/11/21, daniel ccss [EMAIL PROTECTED]: The solution is here: http://balusc.blogspot.com/2006/06/using-datatables.html -- http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces

How to setup secure Cookies
hi, i try to setup myfaces to use only secure cookies (cookies wich are only sent by https). Does anybody know, how to manage this? thx -- View this message in context: http://www.nabble.com/How-to-setup-secure-Cookies-tf4855658.html#a13894655 Sent from the MyFaces - Users mailing list archive at Nabble.com.

josef_a [EMAIL PROTECTED] schrieb: i try to setup myfaces to use only secure cookies (cookies wich are only sent by https). Does anybody know, how to manage this? I've never heard of secure cookies. Cookies are sent from client to server as part of an http (or https) request. Cookies are sent back from server to client embedded in the response. So if the webapp is entirely accessed via https, then the cookies will be encrypted. If the webapp is accessed via http then they will not. In any case, this has nothing to do with MyFaces. The only cookie MyFaces ever uses is the standard http session cookie, and that's a webapp-level issue rather than a JSF library issue. So you need to read about how to configure a WEBAPP with https.

Re: DataTable + Check Buttons
Exactly Simon I applied the Select multiple rows to solved the issue :-) Regards On Nov 21, 2007 4:36 PM, simon [EMAIL PROTECTED] wrote: On Wed, 2007-11-21 at 15:16 -0600, daniel ccss wrote: The solution is here: http://balusc.blogspot.com/2006/06/using-datatables.html Ecch - component bindings. But apart from that, this page looks really useful. The select multiple rows example looks to me like exactly the right solution for this problem: add a boolean selected to the object in the list, then define a column containing a checkbox that maps onto it. Daniel, thanks for posting the link for the archives. I'm sure this will be useful to others. Regards, Simon
Re: DataTable + Check Buttons
Thanks nice example too. I will always askering me which will be the best solution Tomahawk or Trinidad. We decided Tomahawk, but I want to see which will be the better in the future.

Re: Session context was RE: Question about FacesContext
Hi guys... Thank you for replying my question. My EJB is connected to a server which running on difference machine. I do have a listener in my EJB. If something changes in the server that I connected to, it will inform my EJB straight away. The reason I ask that question is, I need to update my page for displaying the latest data that just informed by the server. My EJB have a data and EJB is the trigger point when I should update my page. Normally, the pages will requests the data from EJB. But in my case now, is the opposite way, the EJB request the page to updating the data. The reason why i need the facesContext, I need to access my manage bean and update some data in there. In my page, i do have a poll which will run and refresh the page in every few seconds. Basically, the new data will be display when pollevent is triggered. any idea?

For all intents and purposes they are tightly bound together in webapps. I think that both should be unknown to EJBs or other model/data layers. The boundary between webapps and appservers should allow simple domain objects, but no technology decisions on either side; it becomes a real pain when you want to change a web technology, but the server has become dependent on it. My comment regarding HTTPSessions was more a question of clutter. Obviously you need essential objects, like user key, and objects related to the interaction or user preferences, since they are costly to obtain, and should be near at hand for every subsequent request. The question is whether every class should know exactly how they are stored. And have to fetch them itself. I would prefer a SessionWrapper class that has specific get/set methods with strong typing rather than a free-for-all of hardcoded session queries like: session.getAttribute(isBlueMonday); The session object tends to get bloated, because everyone puts in, but no one dares clean it. You need to pass the session around in every call; it would be better to use a managed bean or a spring bean. This bean can certainly use the session for holding data. But, it is the only one holding the keys, literally. Other classes do not need to find the key or make sure that it's correctly initialized, or decide whether the whole object is stored or just the keys. And best of all, if some session attribute is getting corrupted, you can breakpoint the SessionWrapper access to it. Right now, I have a reasonably complex JSF system. I only keep the some keys related to the principle there. Again, for performance and clustering reasons, an essential (only the essential) session object is much better.

Is it a bad thing too, to access the session in JSF?? I do it all the time to get some beans from the session!! Or do you answerd only the question from pdt! the access to a session from the ejb? naba Neil Pitman schrieb: Hi Pdt, Whoa! That does not sound like a very good thing. JSF is definitely a web-layer/presentation thing. While it might work in JBoss, accessing the HTTP Sessions or HTTP Requests or JSF objects are a really bad idea. Here is a short and incomplete list of bad things that could happen: 1) Web objects are not necessarily serializable, and if they are, then modifications made in an EJB may be lost if the serialization is one way 2) Even if it works, these are big objects with complex graphs of subobjects or sister objects, the performance hit could be large 3) JBoss is outside the EJB spec when it allows collocated web apps and enterprise apps to see each others' class loader. Migration to other app servers will be problematic 4) The dependencies become nightmarish 5) The appserver now depends on the JSF (again, an inversion of dependencies) so that a webservice might need to simulate JSF 6) kiss goodbye to any hope of decoupling the webserver from the appserver for performance reasons. If there is data that you need from the context, like domain keys, then these should be passed in explicitly as parameters to the session beans. These can be fundamental types like Strings, or your own value objects. I have spent the last
binding property in my custom tag is not working
Hi ,
I want to create a custom tag with binding attribute.In the
customTagClass i put property binding .
The Tag class is:
public class CustomPanelGridTag extends HtmlPanelGridTag{
private String paginator;
private String binding;
public void setBinding(String binding) {
this.binding = binding;
}
public void setPaginator(String paginator) {
this.paginator = paginator;
}
public String getComponentType() {
return CustomPanelGrid.COMPONENT_TYPE;
}
public String getRendererType()
{
return javax.faces.Grid;
}
protected void setProperties(UIComponent component) {
super.setProperties(component);
setString(component,paginator,paginator);
// I tried by putting setString(component,binding,binding)
}
public void release() {
super.release();
}
public void setString(UIComponent component, String attributeName,
String attributeValue) {
if (attributeValue == null) {
return;
}
if (isValueReference(attributeValue)) {
System.out.println(attributeName+attributeValue);
setValueBinding(component, attributeName, attributeValue);
} else {
System.out.println(attributeNameattr+attributeValue);
component.getAttributes().put(attributeName,
attributeValue);
}
}
/**
* sets the value binding of an atttibute
* @param component
* @param attributeName
* @param attributeValue
*/
public void setValueBinding(UIComponent component, String
attributeName,
String attributeValue) {
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
ValueBinding vb = app.createValueBinding(attributeValue);
component.setValueBinding(attributeName, vb);
}
}
Component binding is not working with this binding property.
I even tried putting
try {
super.setBinding(binding);
} catch (JspException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
in set Properties method of this tag,then also component instance binding is
not done.
Please let me help in knowing what to do if we want to have a binding
property in the custom tag.It will be great help if any body tell how the
binding propery works done in JSF.To my knowledge , _jspService method
calls the UIComponentTag.setBinding... and after that
UIComponentTag.createComponentInstance is called to create the component
with the instance given by binding property.
Thanks,
Rajeshekar
