Re: JSF Chart Creator and JSF Client Side Validators
Hi, I'd like to use the chart creator component in one of my JSF applications. I followed the installation steps in the manual[1] and copied the jars to the /lib folder. I followed the example in the manual, but when my jsf page is rendered, I just get a broken image icon and a NullPointerException[2] in the log file. Any pointers? Any help really appreciated! Thanks and by the way, there's an upper/lowercase typo in the manual. Installation: step3: the component-type should be chartCreator not chartcreator, right?

Re: Tree2 startup Question-
Matias, I'm not _the_ expert as well, but can't you use the body onload to execute the backing bean methode to expand the tree.

Re: Popup calendar javascript - loadPopupScript not defined
Hi,
thank you for the idea. I followed the thread discussing that the extension
filter needs a head or body tag to be able to add the neccessary
javaScripts.
I do indeed work with a non standalone JSF application, but it's not in a
portal
environment. The thing is called Sakai and is a sort of classroom management
software using frames.
I did check the rendered response and there are proper body and head tags
and additionally there are some javaScript extensionFilter entries defined.
Just to show two examples:

Re: How to get currently selected node of tree2 component
Hi Hans, thank you for this hint! This looks like somethink that should work. The question is only, why the HtlmTree.getNode() is reset anyway after the listener. But I think this is out of scope for now. How did you find out about this updateActionListener? I just found the JavaDoc entry after you pointed this listener out to me. Additional the doc is not very descriptive in terms of functionality. Again, thank you very much! Take care, Kurt
h:inputTextarea bug?
Hi everyone,
I ran into a problem by using the inputTextarea component of myfaces-1.1.1.
I simply like to display some editable text by adding
h:inputTextarea id=patientHistory rows=#{configBean.patientHistoryHeight}
cols=#{configBean.patientHistoryWidth} value=#{bean.patientHistory}/
to my jsp page. The application crashed with an ClassCastException [1] while
retrieving the attribute cols for the tag.
The two methods configBean.getPatientHistoryHeight and configBean.getPatientHistoryWidth are
returning two Strings like 10 and 40 respectively. I double checked this by
adding
h:outputText value=#{configBean.patientHistoryHeight}/ by
h:outputText value=#{configBean.patientHistoryWidth}/
to my page, which renders properly showing: 10 by 40
If I replace the value bindings for rows and cols by actual numbers, the
application works fine.
Any ideas why I can't use value bindings, which are returning string values,
with the inputTextarea component??
Thank you for your help in advance,
Kurt

Re: How to get currently selected node of tree2 component
Hi Daniel,
thank you for your answer. That's probably a better way than using
another bean property to store the selected node in the listener. But
why and when is the tree.getNode() reset? If you set the node
explicitely by tree.setNodeSelected(evt) is this persistent until the
next node is selected?
Thank you again and sorry for the late response,
Kurt
on 12/14/2005 2:53 AM Lefevre, Daniel stated:
Hello,
My (short) experiences shows that the getNode() method returns the node
which is selected in the htmlTree. Then the getNode() method returns the
selected node only in your selection event or via the htmlTree, when you
have set it explicitely.
What I do is as follows:
- in my selectNode method (actionListener), I take the selectedNodeId
and set the selected node of the htmlTree.
public void selectNode(ActionEvent event)
{
// set the selected status on the node of the tree
htmlTree.setNodeSelected(event);
selectedNodeId = htmlTree.getNodeId();
}
- in the other actionListeners, I access the selected node by using the
selectedNodeId.
public void addNode(ActionEvent event)
{
// get access to the selected node
htmlTree.setNodeId(selectedNodeId);
MyTreeNode node = ((MyTreeNode) treeModel.getNode());
.
.
.
}
The used variables being declared as follows (with getters and setters
of course):
private TreeModel treeModel;
private transient HtmlTree htmlTree;
private MyTreeNode selectedNode;
private String selectedNodeId;
This is maybe not THE solution, but it works.
Hope this helps,
Bye, Dan

Quick question - is it possible to attach more than one action listener
method to a commandLink component using the JSF EL? Effectively, could I
do something like this?
h:commandLink actionListener=#{EL gobbledygook here}
h:outputText value=dummy/
/h:commandLink
I have two separate backing beans that provide separate functionality
when the *same* ActionEvent fires. It seems reasonable to allow more
than one listener on an event, I just don't know how to write the JSF
expression for it, and documentation on the EL that I've found so far
doesn't discuss this. Obviously, I know how to write expressions to
register one listener with #{beanName.methodName}.
Any clues?

Hi Darren,
I was looking for such a component to be able to embed SVG graphics in a

It was pretty much straight forward to implement a custom component

pluginspage, and type.
If you would like to use this tag, I'll could provide you with the

the code ;)

How to get currently selected node of tree2 component
Hi, I'm having another issue with my tree2 component. I'm using a TreeModelBase field to be able to access the currently selected node within my backing bean, which should be possible regarding to the Javadocs by using the method getNode(). I have a page with a tree2 component, from which I can select a node and this node is highlit according to the css styles. If I invoke a method in the backing bean where the tree2 is hosted as well by pressing an commandButton, I don't get any values for TreeModelBase.getNode(). The value remains 'null' regardless if a node is selected in the tree or not. I attached an ActionListener to the nodes and when this is invoked, the TreeModelBase.getNode() method is actually returning the currently selected node (which has triggered the listener). I have verified that I'm dealing with the same instance of the bean with a debugger and they are indeed the same. Why can't I access the currently selected node in the backing bean though in the action listener? I don't have any validators attached to the component and also a generic h:messages/ in the same jsp page doesn't print any errors. Any thoughts? What would be the best practise to access the currently selected node? Thanks for any help, Kurt

Re: StartupServletContextListener crashes Tomcat container
Jeff, the error message just say that the exception occured in FacesServler.service but doesn't tell you anything about the reason. If you'd like to find out, you have to look into tomcat's log file for some stacktrace telling you what caused the crash. But anyway, since you are having trouble to get the whole JSF thing running, I'd recommend you to give it a fresh start and look into one of the different tutorials or quickstart applications like Equinox or AppFuse. You can find them at https://equinox.dev.java.net/ and https://appfuse.dev.java.net/ respectively. Once these apps are running, you know your setup is fine and can start developing your own application.

But had you ever the chance to take a look at the jsftags-guide examples
(http://www.exadel.com/tutorial/jsf/jsftags-guide.html)?
They are using the SelectItems directly. Where's the difference?
The page shows this example:
h:selectOneMenu id=selectCar
value=#{carBean.currentCar}
f:selectItems
value=#{carBean.carList} /
/h:selectOneMenu
But where does it say what datatype method getCurrentCar is returning?
I would think it returns String, eg accord.
And likewise, I would expect setCurrentCar to take a String parameter,
which will be one of accord, 4runner, nissan-z depending on what
the user chooses.

Re: h:selectOneMenu question
Hi Simon, the exadel example jar actually runs without any problems and I don't see any custom converter configured. I don't know why this is the case, this was the reason for starting this thread anyway ;) I modified my classes to handle Strings in the getter and setters and now it works. I still would like to know why the exadel example handles javax.faces.model.SelectItem directly. Regards, Kurt on 12/8/2005 2:36 PM Simon Kitching stated: Simon Kitching wrote: Kurt Edegger wrote: Let me post the carBean class to show that 'carBean.currentCar' accesses the SelectItem directly [1]: Hmm..interesting. Thanks for posting that. However I can't see any Converter class in MyFaces that is capable of doing String-SelectItem conversion. The Converter methods do get passed the associated UIComponent, so potentially such a converter could access its parent component in order to iterate over its child SelectItem objects. It must be possible, as the example jar clearly does it. However I can't figure out *how* the UISelectOneMenu can use a value-binding dealing in SelectItem instances. I'd be very happy if someone could explain! Of course, specifying the value binding as a primitive property (String/int/etc) works fine. Looking at the official Sun javadoc for the SelectItem class, the getValue() method is defined as follows: quote Return the value of this item, to be delivered to the model if this item is selected by the user. /quote This sure implies that the value attribute of the enclosing t:selectOneMenu should point to a property that takes objects of the same type as is returned by SelectItem.getValue(), rather than taking a complete SelectItem instance. The MyFaces examples dir has selectbox.jsp, whose backing bean is class CarConfigurator.java. This example always maps the select component's value attribute to primitive properties, eg public String getCar(); public int getDoors(); Does the exadel example jar actually run? Cheers, Simon
h:selectOneMenu question
Hi everybody,
I'd like to use a dropdown menu in my jsp page, therefor I added
h:selectOneMenu id=selectModifier value=#{bean.currentItem}
f:selectItems value=#{bean.itemList} /
/h:selectOneMenu
to my page. The bean provides getter and setters for both properties, whereby
currentItem is of type SelectItem and itemList is an ArrayList containing
SelectItems.
Just a static example copied from jsftags-guide into my bean class:
private SelectItem currentItem;
private ArrayList itemList;
public SelectItem getCurrentItem() {
return new SelectItem(4runner,Toyota 4Runner,Toyota 4Runner - suv);
}
public void setCurrentItem(SelectItem currentItem) {
this.currentItem = currentItem;
}
public ArrayList getItemList() {
this.itemList=new ArrayList();
this.itemList.add(new SelectItem(accord,Honda Accord,Honda Accord -
sedan));
this.itemList.add(new SelectItem(4runner,Toyota 4Runner,Toyota 4Runner -
suv));
this.itemList.add(new SelectItem(nissan-z,Nissan Z350,Nissan Z350 -
sports));
return itemList;
}
public void setItemList(ArrayList itemList) {
this.itemList = itemList;
}
But whenever I try to render the page, I'll get an
'java.lang.IllegalArgumentException: Value is no String and component
treetestformdb:selectModifier does not have a Converter' Exception.
IMHO the returned SelectItem should be rendered as a String automatically
without the need to attach a custom converter.
What am I'm missing here? I'm banging my head for an hour now,
Kurt

Bean definition question faces-config.xml
Hi, I wonder if it is possible to declare the constructor of a bean in faces-config.xml similar to using constructor-arg in spring's configuration files. The idea behind this is, that I'd like to inject a bean into my application and use a referenced bean already in the constructor. As far as I know and encountered, first the default constructor is called, then the referenced beans are injected by using the corresponding setters, and finally the bean is used in the application depending of the scope. Or is possible to use/reference Spring beans in faces-config.xml? Thank you for your answers, Kurt
Re: Bean definition question faces-config.xml
Thank you for your fast response!

[...snip...]
This is definitely not a feature of the JSF specification, and MyFaces
can't add any new tags to the faces-config.xml file without violating
the spec.
Ok, short and precise answer ;)
[...snip...]
You can also do initialisation after all the properties have been set.
See the FAQ entry How do I know when a managed bean's properties have
all been set?.
There's a method called initDao() in the class
org.springframework.jdbc.core.support.JdbcDaoSupport which should be
overwritten in a case you need to init a DAO (which is the case in my
situation).
But this one is not called by JSF right? So I'd need to use spring to
construct the bean?
Thank you for pointing to the FAQ - missed that one ..
Take care, Kurt
http://wiki.apache.org/myfaces/FAQ
Or is possible to use/reference Spring beans in faces-config.xml?
Any managed-property like:
managed-property
namefoo/name
value#{someValue}/value
/managed-property
simply looks for a key someValue in the request, session and
application scopes. So if your spring bean is stored in one of those
maps then it will be passed to the managed bean on creation.

Simon
Re: naming conventions in faces-config.xml
Hi Mike,
thank you for your help, but I don't think that your answer is correct.
We are talking about two different classes. The first one is
CasesJdbcDAO with the setter taking an JDBCDataSource Object and the
second on is the JDBCDataSource class having a getDs() method to return
the actual javax.sql.DataSource object. To clearify: The JDBCDataSource
object is injected to CasesJdbcDAO using the setter in CasesJdbcDAO
which takes the correct type of JDBCDataSource.
I don't think this is an issue of a misscasted type since it works if
the field in CasesJdbcDAO (marked as [1] in my former postings) isn't
named 'dataSource'. In that case the JSF implementation seems to
interpret the name as a type and causing the exception. In the case it
isn't named 'dataSource' (e.g. 'ds' in my example) the injection is done
without any problems.
I'm appreciating your help and thoughts.

naming conventions in faces-config.xml
Hi,
I do have a question relating to properties of managed beans defined in
faces-config.xml. I do face the following situation of two beans:
managed-bean
managed-bean-namejdbcDataSourceBean/managed-bean-name
managed-bean-classJDBCDataSource/managed-bean-class
managed-bean-scopeapplication/managed-bean-scope
/managed-bean
managed-bean
managed-bean-namecasesDAOBean/managed-bean-name
managed-bean-classCasesJdbcDAO/managed-bean-class
managed-bean-scopesession/managed-bean-scope
managed-property
!-- [1] --
property-nameds/property-name
value#{jdbcDataSourceBean}/value
/managed-property
/managed-bean
The first bean is injected into the second one and everything works
fine, but as I wrote the code I decided to name the managed-property of
the second bean 'dataSource' since it's more descriptive.
I renamed the field in the class and the setter as well.
But when the casesDAOBean is contructed at runtime, the application
crashes with an exception 'javax.servlet.jsp.el.ELException: Attempt to
coerce a value of type JDBCDataSource to type javax.sql.DataSource'.
Somehow the property name is recognized as type, even I had to declared
it in CasesJdbcDAO anyway (JDBCDataSource dataSource; ).
Why am I not allowed to call the field like a class in the package
javax.sql?
I had a hard time to find this one, since I wouldn't think of simply
renaming the field solved the issue.
Any clues why this happens?
Thanks,
Kurt

Issues adding childNodes to TreeNode elements when using Tree2 component
Hi!
I'd like to use a tree2 component in my JSF application.
The entries are aquired via a DAO from a database. The DAO holds a list
containing the entries in the tree describing the entry itself and the name of
the parent node where it should be attached to (the names of the nodes are
unique).
I'm parsing the list and attach a new TreeNode to the root for each entry where
the parent node is either root or not defined. To add the child nodes, I'm
searching the tree and if the parent node is existing I'm adding a new TreeNode
to the parent one.
But after I added the child to the parent, the tree.getChildCount() method still
returns the number of nodes without the child.
What could be the reason for loosing the child node after adding it to the
tree?
Here's a small code snipplet to demonstrate:
nodeIdentifier = parentNodeIdentifier;
TreeNode parentNode = getNode(treeData, nodeIdentifier);
TreeNodeBase groupNode=null;
if (parentNode!=null){
int index = treeData.getChildren().indexOf(parentNode);
TreeNode pNode2 = (TreeNode) treeData.getChildren().get(index);
//pNode2 is the same as parentNode as expected
nodeIdentifier = childNodeIdentifier;
groupNode = new TreeNodeBase(type, name, nodeIdentifier, false);
//[1]
parentNode.getChildren().add(groupNode);
//[2]
}
treeData holds the root of the tree as a simple TreeNodeBase element.
parentNode.getChildCount() return 0 at [1] and 1 at [2] as expected,
but treeData.getChildCount() returns 1 at both positions of the code.
Even if I add the parentNode explicitely again to the tree, the number of childs
in the tree is increased only by 1 (the parentnode) and not by 2
(parent+child).
What am I missing here? Is there an easier way to construct a tree which has
more than one level of children?
Any help appreciated.
Thank you,
Kurt

jsCalendarPopupCalendar not embedded
Hi,
I would like to use the inputCalender element on one of my jsf pages.
I'd like to have the element rendered to use the javaScript popup to
display the calendar. But when I add the following to my jsp document, I
only get an jsCalendarPopupCalendar is not defined JavaScript Error
after clicking on the calendar icon next to the input field.

I did add the extension filter entries to my web.xml and I can use other
elements correctly. I found a former thread in this group relating to
the same issue, but there the issue was that the jsp document had no
body nor head elements, which I do have both in my jsp.
Any ideas?

It seems to be a CSS issue, but I copied the CSS from the source distribution. The CSS is readbecause I can change attributes like font size and color. How do I get rid of the spacing between the actual tables (each row a table on its own, right?)? Please find a small image of the rendered response (a pic says more than 1000 words). Thank you for your help, Kurt
