t:columns openDataTable.jsp: openDataList -- request scope
Hello,
When I change the backing bean openDataListto request scope, I got the exception when I click any header to sort.
javax.servlet.ServletException: Cannot get value for _expression_ '#{openDataList.data}'
If I set preserveDataModel=true or t:saveState value="#{openDataList.data}"/ or both, I still got the exception. What is wrong? When the backing bean is instantiated, its data model is created in the default constructor.
Does the backing bean have to be session scope?
Thanks for help. Dave

Re: t:columns data conversion
h:column or t:columns do not make any data conversion. The UIInput
component does it. Can you post your jsp code?
2005/9/16, Dave [EMAIL PROTECTED]:
Previously I used h:column with dataTable, data conversion was done by JSF
between String/Integer, String/BigDecimal. When I changed it to use
t:columns for variable number of columns, I got error.
Cannot set value for expression '#{backingBean.columnValue}' to a new value
of type java.lang.String
In the backing bean:
public Object getColumnValue();
public void setColumnValue(Object value);
The value passed into setColumnValue() is always String.
t:dataTable does not keep track of data type for each column and then
convert data automatically. So I need to make data conversion in
setColumnValue(Object value) for all columns.
Am I correct? Thanks! Dave

Re: t:columns resource bundle
AFAIK the resource bundle is only loaded once. But this depends on the
implementation for the resource boundle I think.
2005/9/15, Dave [EMAIL PROTECTED]:
When I use t:columns for variable number of columns in dataTable, I need
to call getResourceBundle() from ViewRoot, and then call
resoucebundle.getString(Label). In JSP, I just use #{bundle.Label}. Is
there any performance overhead? Is there a better way to display localized
string from a backing bean such as for t:columns? I am trying to
understand how JSP manage resource bundle? does JSF need to access disk
everytime I call getResourceBundle() or everytime a page loads that declares
a resouce bundle? or any cache going on? Thanks. Dave

Re: rendering a custom component
This code snippet from my last project should give you a good hint:
HtmlOutputText iconDesc = (HtmlOutputText)
app.createComponent(HtmlOutputText.COMPONENT_TYPE);
iconDesc.setValue(xxx);
try
{
RendererUtils.renderChild(ctx, iconDesc );
}
catch (IOException e){e.printStackTrace();}
I hope this answered your question?

Re: PreserveDataModel behaviour (2)
Any comments? I think this is a serious issue...2005/9/15, Enrique Medina [EMAIL PROTECTED]:
Hi again,
I have investigated another interesting behaviour about using
PreserveDataModel, which makes my application crash (due to the way I'm
working with data tables). Let me explain it to you in a
straight-forward manner.
Currently, I use a session scoped bean to work with my objects (e.g.
one bean to work with customer objects, one bean to work with the
users, etc), due to the fact that I don't want to loose state between
requests (yes, I know it could have been done using
t:saveState...). So within all my session beans, I have defined
a ListDataModel variable that holds the data model that is presented to
the view every time the view is rendered (nothing strange here, I
guess).
>From my views (JSP), I simply use:
t:dataTable .. value=#{sessionScopedWhateverBean.listOfObjectsAsListDataModel}
So whenever the view is rendered, the method public DataModel
getListOfObjectsAsListDataModel() in my session scoped bean is
invoked. Obviously, the first time it will be created, and the
subsequent calls simply will return the existing object. Everything's
fine here.
The problem comes when using PreserveDataModel because, as explained in
the wiki I posted about working with PreserveDataModel, every object in
my listOfObjectsAsListDataModel is added to a new ArrayList belonging
to a new _SerializedDataModel object, which is the object being really
serialized when saving the state by the JspStateManagerImpl. And why is
it the problem? Think about the future restoring phase...
When a link is clicked inside the data table to work with a particular
object, the event created as a consequence of the clicked link has
the information about the exact row which has been clicked
(specifically in its rowIndex attribute). Following, the state is
restored, and the previously serialized data model (as a
_SerializedDataModel object) is used to set the information about the
clicked row. What does this mean? It's as simple as this: the
clicked row information is set on the restored object, so it is
really set on the _SerializedDataModel object (nothing to be with our
original ListOfObjectsAsListDataModel object).
When afterwards the broadcast calls our action method (the one
associated with the link in the data table through usually an
HtmlCommandLink tag), our session scoped bean has the original
ListOfObjectsAsListDataModel object that was used to create the
_SerializedDataModel object when saving the state. But with a
definitive difference: the rowIndex from the event was set on the
_SerializedDataModel object, not the one we have here now, i.e. our
ListOfObjectsAsListDataModel object. And due to the fact that our
ListOfObjectsAsListDataModel was used to create the
_SerializedDataModel object, now it has its internal rowIndex attribute
set to the last row plus one (obviously, as the saveState method
iterates through the ListOfObjectsAsListDataModel list of objects to
populate the _SerializedDataModel list of objects).
At the end, the result is a call to setRowIndex(last row + 1), which
obviously does not exist, so a IllegalArgumentException: row is
unavailable is thrown. On the other hand, if I don't use
preserveDataModel, everything works perfectly, as the
ListOfObjectsAsListDataModel object is the one used to save the state
(not the _SerializedDataModel).
IMHO, the solution will be as simple as updating my
ListOfObjectsAsListDataModel object with the _SerializedDataModel
object when restoring the state. But I would like to hear the MyFaces'
team experts about this possibility before going deeper into the code.
Is it feasible? Is it possible to work with the preserveDataModel
together with a DataModel inside my bean and the getRowData() method?
Is the use od preserveDataModel incompatible with using the
getRowData() method inside my bean?
Looking forward to hearing your comments :-)
Re: PreserveDataModel behaviour (2)
Hi Martin,
What does 'ev' stands for?
One of the possible solutions I suggested was, the same way a new
_SerializedDataModel is generated from the current data model (my own
ListOfObjectsAsListDataModel), to assign the serialized data model to
the original data model in the restoring data phase.
Please also note that I also posted a solution to the problem of lazy
loading in Hibernate through the use of a LazyListDataModel object via
callback mechanisms (so this will also not work with
preserveDataModel...).2005/9/16, Martin Marinschek [EMAIL PROTECTED]:
Well,the preserveDataModel feature was not programmed especially for thisuse, I would say. I understand your interest for such a usecase,though.Were I've got my problems is that with normal valueBindings for the
dataTable, the model of the backing bean will not be used until therender response phase, instead the serialized data model will be used- for me this means that you will need to use the serialized datamodel in your backing bean as well.

[newbie] How to display dynamic content from a database
I would like to write a JSF-application that displays a data-list from a database.The amount of entries in that list, however, differs.My question is:I assume I have to place that data into the backing bean BEFORE the page is rendered. How do I do that? I actually have two use cases:Case 1: Upon its first call, a page has to display such a data list (so somehow I need to be able to place the data from the database into the backing bean BEFORE the page is displayed)Case 2: A page is called by another page which passes a key to the new page. The new page has to then use that key to query the database (Key can be a search criteria or such. It is usually an integer)How can that be done?ThanksEstherVerschicken Sie romantische, coole und witzige Bilder per SMS!Jetzt bei WEB.DE FreeMail: http://f.web.de/?mc=021193

Re: [newbie] How to pass a parameter from one page to another
with a commandLink, you could use the f:param tag. A cool MyFaces specific feature is the t:updateActionListener tag - you can set a value onto a backing bean if a command has been executed. Another possibility is to write an actionListener instead of an action method and use the supplied ActionEvent to get to the component and e.g. to the dataModel of a wrapping dataTable. regards, MartinOn 9/16/05, Esther Leimbeck [EMAIL PROTECTED] wrote: If I have a commandLink or commandButton on one page to which I attach a value (e.g. an integer or even a bean) – how can I pass that on to the next page so that the bean of the next page knows this value?

I'm stabbing in the dark here since this is all new to me also. It
doesn't look ilke you need to saveState of listener since your rendered

saveState and just put:
x:saveState id=foo value=#{foo}/
Maybe you can have more than one saveState on a page and only the first
one is getting called?
Also make sure the bean backed by foo is serializable (at least I think
it needs to be for saveState to work).

Thomas Spiegl wrote the following on 9/16/2005 10:14 AM:

That's not what I'm asking though. I'm asking about how to use the
t:updateActionListener tag. I'm thinking the tag would be used inside of
a commandLink or commandButton tag and when the action is fired that the
link or button represents, it will automatically set and bean properties
of the backing bean backing that action? If so, this would be a SUPERBLY
nice feature.
Currently, for example if you pass in parameters with a commandLink you
need to do the following in the resulting action (assuming foo is the
f:param):
FacesContext context = FacesContext.getCurrentInstance();
Map map = context.getExternalContext().getRequestParameterMap();
String foo = (String) map.get(foo);
I'm assuming that possibly t:updateActionListener would avoid this
construct and that if you had a property in the Action called foo it
would be automagically populated using the tag. This would be very nice
- so nice, that I think it should be part of standard JSF.

Are there any good examples of using Shale with MyFaces? In particular, I would like to see some examples of Clay so that I can better understand how this works. I am launching a new project in which JSF will be used and would like to put in place a good templating solution. Thanks, Brad
Re: [newbie] How to pass a parameter from one page to another
Rick,
My answer was related to Esther Leimbeck's question.
When using the updateActionListener nested inside a commandLink, the backing bean will automatically be updated.
Have a look at the Master-Detail example:

of the backing bean backing that action? If so, this would be a SUPERBLYnice feature.Currently, for example if you pass in parameters with a commandLink youneed to do the following in the resulting action (assuming foo is the
f:param):FacesContext context = FacesContext.getCurrentInstance();Map map = context.getExternalContext().getRequestParameterMap();String foo = (String) map.get(foo);I'm assuming that possibly t:updateActionListener would avoid this
construct and that if you had a property in the Action called foo itwould be automagically populated using the tag. This would be very nice- so nice, that I think it should be part of standard JSF.

validator question
I have a issue here, I define a validate method in backing bean
dealerPricing, we need validate force user must input at least 2 non
space letters, otherwise we may have legal issue, like somebody enter
spaces instead enter nothing. So we can't use default request
validator. I made a validator in bean. But we found my validator will
never be called if we put required=ture; if I remove required=true,
it will never be called when user enter nothing. I don't want create a
customized validator for this simple issue.
h:inputText id=whoShopped
value=#{dealerPricing.dealerVehicle.whoShopped}
validator = #{dealerPricing.validateWhoShopped}
required=true
rendered=#{!dealerPricing.isAA}/
Thanks.-- Zhong LiWebJabber.Net
Re: validator question
Does your submit button have immediate=true. If immediate is set to
true the validation phase is skipped. Is that your problem?

Re: validator question
If required=true and no data is provided, then validation isn't
checked (there's nothing to validate). Instead, the component will
throw a validation exception.
If required=true and data is provided, then your validator will be run.

Re: [newbie] How to display dynamic content from a database
the MasterDetail covers your problem

Just read the data from database, pack it into a java.util.List and pass it to your dataTable

somehow I need to be able to place the data from the database into the

Case
2: A page is called by another page which passes a "key" to the new

Have a backing bean hold on to a Collection (or maybe a bean holding a
Collection). You call a method in that backing bean that populates the
collection when you click on a link or button. The resulting page you
go to then just uses this Collection for the dislay.
Case
2: A page is called by another page which passes a "key" to the new
page. The new page has to then use that "key" to query the database
(Key can be a search criteria or such. It is usually an integer)

A couple ways. The cleanest solution seems to be using the updateActionListener tag that Thomas just introduced me to.
So for example I have a link in a table that looks like...
t:dataTable var=emp
t:commandLink action="">
h:outputText value=#{msgs.edit} /
t:updateActionListener property=#{employeeAction.employee.id}
value=#{emp.id} /
/t:commandLink
In the backing bean employeeAction there is an employee
reference. Clicking on the link above will set the Id of employee
in my EmployeeAction's 'prepareForEdit' method. It's very nice.
Character scaping inside f:verbatim
Guys, even if scape is false, some international characters keep being scaped inside f:verbatim. For example, ç gets scaped to #231; This is correct inside normal html, and the browser displays the correct character. But it gets messed when JSF outputs _javascript_ that is inside a f:verbatim tag body. All my alert messages that are displayed comes with the escaped characters. Is this normal behaviour or am I doing something wrong?

t:columns How to render different UI for each column
Some column is boolean type, need a h:selectBooleanCheckbox
some column is choice, need a h:selectOneMenu
The openDataTable.jsp example uses a flag to render h:inputText or h:outputText.
but what is the way to render different UIcomponent for each column? Thanks.
t:columns id="columns" value="#{openDataList.columnHeaders}" var="columnHeader" style="width:#{openDataList.columnWidth}px"

Re: [newbie] Forward to launch page
Hey Rick! It's nice to see a familiar name. Nice JSF example on your site. I'm using it to see where the heck I'm screwing up. Here's my directory set up: /index.jsp /css /images /javascript /pages/launch.jsp /WEB-INF Here's a snippet from my web.xml - snip servlet-mapping servlet-nameFaces Servlet/servlet-name url-pattern*.faces/url-pattern /servlet-mapping /snip Here's a snippet from my faces-context.xml file. This is really the only thing I have in it besides the doctype. -- faces-config navigation-rule navigation-case to-view-id/pages/launch.jsp/to-view-id /navigation-case /navigation-rule /faces-config Here's my index.jsp file: -- jsp:forward page=/launch.faces/ This set up produces a 404 error: --- HTTP Status 404 - /launch.jsp type Status report message /launch.jsp description The requested resource (/launch.jsp) is not available. Notices there is no mention of /pages directory in the error message. Now, if I copy or move the /pages/lauch.jsp to /launch.jsp AND make no other changes, redeploy. The page is found and is rendered. As long as launch.jsp resides directly under the webapp root context, I can even change to-view-id/pages/launch.jsp/to-view-id to to-view-id/launch.jsp/to-view-id and it is found. It's as if the /pages part of the view-id is being stripped out. I'm going to have a look at the source in org.apache.myfaces.application.jsp.JspTilesViewHandlerImpl to see if I can tell what's happening. Any ideas? Have you seen any examples where the pages reside in a subdirectory instead of directly under the web app root context?

My dev. env. consists of Tomcat 5.5.9, MyFaces 1.0.9, JDK 1.4.2, Win2K. I've configured MyFaces to use Tiles for view-handler. What I want to do is to have my welcome page (index.jsp), forward to a launch page for the application. In Struts, I would simply use a jsp:forward page=/app/launch/. In my struts-config.xml file I has an action mapping for action path=/launch forward=launch.tile/ which forwarded to a tiles configuration which builds the page. I'm trying to do something similar with JSF, but have been unsuccessful. I removed the tiles complexity just to see if it would display a non-tiles .jsp.

Re: [newbie] Forward to launch page
Well I believe your index page of: jsp:forward page=/launch.faces/ Is going to try to find /launch.jsp in the root but you don't have launch there so make it: jsp:forward page=/pages/launch.faces/ and you should be all set. Also this rule: navigation-rule navigation-caseto-view-id/pages/launch.jsp/to-view-id /navigation-case/navigation-rule I don't think will do anything since you don't have a from-outcome defined, so I'm not sure what the above will ever do. I think you are expecting the to-view-id to fire based on the forward set up in your index, but that's not the case since that forward is going to try to resolve to a jsp (which doesn't exist in your root).
Re: [newbie] Forward to launch page
From: Robert Taylor [EMAIL PROTECTED] /pages/launch.jsp jsp:forward page=/launch.faces/ What happens if you use: jsp:forward page=/pages/launch.faces / ? I don't think the navigation rules are coming into play at all, this is just strip off the .faces extension and look for a .jsp with the same name. The requested resource (/launch.jsp) is not available. Notices there is no mention of /pages directory in the error message. ... and that makes sense to me, because you told it to forward to /launch.faces, so it's looking for /launch.jsp. -- Wendy Smoak
