java.lang.IllegalStateException in tree2
Hi,
I am getting the following exception in tomahawk tree2 while
fetching the data
from database and constructing the tree:
java.lang.IllegalStateException: Encountered a node [0:0:0] +

tempNodeBase.getChildren().add(new
TreeNodeBase("foo-folder",tempChildList.get(cnt).toString()

treeData.getChildren().add(tempNodeBase);

Re: Inline validation method
Thanks David.
Is this "validator" attribute something added in JSF 1.2? I'm sure it
doesn't exist in JSF 1.1 (which is what MyFaces 1.1.x supports).
The article doesn't specify what JSF version each of the demonstrated
features is available in..
Cheers, Simon
David Chandler wrote:
FYI, here's the link to the original article:
http://www-128.ibm.com/developerworks/library/j-jsf3/
It simply illustrates inline validation in JSF 1.1, and Simon is
correct that the bean validator method gets passed a component
reference (along with faces context, and an Object value to validate).
In practice, the easiest way to code the correct signature for a bean
validator method is to use your IDE to auto-create the validate()
method by having your managed bean implement the
javax.faces.validator.Validator interface. The bean doesn't actually
have to implement the interface, nor does the method have to be named
validate, but it's a convenient way to create the code.

It would be nice if you gave a URL to the quoted article. I guess this
is some IBM proposal to add a feature to JSF (presumably for the JSF 1.3
or 2.0 releases).
At the point that validation runs, the "update model" phase has not
executed. So if you were to try to access the managed-bean property
specified in the "value" attribute, it wouldn't yet have the new value.
This is really the *point* of validation - checking before updating
model.
So to get the value to be validated, you must ignore whatever the
"value" attribute points to, and instead get the data directly out of
the JSF component.
I presume their proposed "validator" method gets passed the relevant
UIComponent object (an HtmlInputText in this case).

Re: changing styles in tobago
Hi Sascha,
you can add (and configure in the tobago-config.xml) a resource
directory for tobago to your application.
in this directory you need to create the tobago resource directroy
structure and there you can put a file "style.css" to overwrite the
styles.
e.g. to change the background color of the box in speyside theme to yellow:
1. create a directory "tobago-resource" in your webapp.
2. configure this directory as tobago resource directory in tobago-config.xml
tobago-resource
3. create the tobago resource directory stucture in this directory
"html/speyside/standard/style"
4. create a file with name "style.css" here with this content:
.tobago-box-content {
background: yellow;
}
thats all.
But be carefull changing any other than colors! You may destroy the
layout, because layout calculation depends on the "known" sizes,
borders, margins etc.

Volker

Change SelectMenu default value
Hi, I have a form where the default value of a SelectOneMenu item is dependent on a Date field value and associated validations. When the user enters a date in the date field, a date comparision logic along with a check of another static value, decides the value of the selectitem of the SelectOneMenu to be displayed on the page. This is entirely a client side operation, before any buttons/links are clicked or form submitted. I was thinking of using javascript , but javascript and jsf dont go well together. My second thought is to use a cleint side validator, but am not sure how to do this. What is the best way to do this? Your suggestions are most appreciated.

RE: How to get client browser's resolution.
There is no standard method for this on the browser or the server, and generally trying to code for this is bad practice anyways. Imagine, for a second, that you did some sort of magic to get the dimensions and depth, which you then pass to the server which returns the page with the necessary styles defined. Now the browser has displayed/rendered the page, and the user manually changes the size of the window (maximize, minimize, restore), the color depth, etc. None of these things automagically cause a page reload, so all of that complicated stuff you went through to get a pretty page at some resolution now looks like crap. -Original Message- From: Adrian Mitev [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 03, 2007 10:39 AM To: MyFaces Discussion Subject: How to get client browser's resolution.

RE: does not work properly when added programmatically- Any help
Hi David,
Thanks for a quick response. I changed the way encoding is done to what you
have suggested.
I have overridden the getRendersChildren method to return true so that
encodeChildren of this custom component will only get called.
However if you look at the code of HtmlNavigationMenuRenderer - renderer for
you will find that getRenderesChildren will return true.
This means that in the method that you have provided following will happen:
Note: There is only one child HtmlPanelNavigationMenu for this custom
component. This component in turn has many HtmlCommandNavigationItem components.
1. child.encodeBegin gets called
2. child.encodeChildren gets called
3. child.encodeEnd gets called.
Child component passed is HtmlPanelNavigationMenu.
Unfortunately nothing changes. Problems persist the way they were.

The above line is suspicious. If you want to handle yourself your
component's child rendering process, you must do it more cleanly. Most
component don't render their childs by themselve. Most probably, your
call to encodeChildren() only do a partial work, explaining difference
you get.
Here is an example code i use when i need in a custom rendered to manage
myself rendering of childrens:
private void encodeChild(FacesContext context,UIComponent child)
throws IOException{
if (!child.isRendered())
{
return;
}
child.encodeBegin(context);
if (child.getRendersChildren())
{
child.encodeChildren(context);
}
else
{
for (int i = 0;i< child.getChildren().size(); i++)
encodeChild(context,
(UIComponent)child.getChildren().get(i));
}
child.encodeEnd(context);
}
Just call this method when you need to render one of your childs.
don't forget to override the getRendersChildren() and encodeChildren()
of your custom component btw.
Re: Inline validation method
FYI, here's the link to the original article:
http://www-128.ibm.com/developerworks/library/j-jsf3/
It simply illustrates inline validation in JSF 1.1, and Simon is
correct that the bean validator method gets passed a component
reference (along with faces context, and an Object value to validate).
In practice, the easiest way to code the correct signature for a bean
validator method is to use your IDE to auto-create the validate()
method by having your managed bean implement the
javax.faces.validator.Validator interface. The bean doesn't actually
have to implement the interface, nor does the method have to be named
validate, but it's a convenient way to create the code.

It would be nice if you gave a URL to the quoted article. I guess this
is some IBM proposal to add a feature to JSF (presumably for the JSF 1.3
or 2.0 releases).
At the point that validation runs, the "update model" phase has not
executed. So if you were to try to access the managed-bean property
specified in the "value" attribute, it wouldn't yet have the new value.
This is really the *point* of validation - checking before updating model.
So to get the value to be validated, you must ignore whatever the
"value" attribute points to, and instead get the data directly out of
the JSF component.
I presume their proposed "validator" method gets passed the relevant
UIComponent object (an HtmlInputText in this case).

does not work properly when added programmatically - Any help
Hi All,
I have a custom component which contains HtmlPanelNavigationMenu -
component class for .
This in turn contains a number of - component
class HtmlCommandNavigationItem
This is how I create the component:
HtmlPanelNavigationMenu panelNavigationComponent =
(HtmlPanelNavigationMenu)app.createComponent(HtmlPanelNavigationMenu.COM
PONENT_TYPE);
panelNavigationComponent.setId("leftNav");
panelNavigationComponent.setLayout("list");
// Set the CSS classes for the panelNavigation2 component
panelNavigationComponent.setActiveItemClass("navSelected");
panelNavigationComponent.setOpenItemClass("navOpen");
panelNavigationComponent.setItemClass("navNormal");
//Adding child components
Element rootElem = doc.getRootElement();
List children = rootElem.getChildren();
Iterator parentIter = children.iterator();
//Iterate through the children
while (parentIter.hasNext()) {
HtmlCommandNavigationItem commandNavigationItem = null;
Element node = (Element) parentIter.next();
if ("true".equals(node.getAttributeValue("visible"))) {
commandNavigationItem =
(HtmlCommandNavigationItem)
app.createComponent(HtmlCommandNavigationItem.COMPONENT_TYPE);
commandNavigationItem.setId(node.getAttributeValue("id"));
FacesUtils.setAction(commandNavigationItem,
node.getAttributeValue("action"));
commandNavigationItem.setImmediate(true);
// Create the panel grid
HtmlPanelGrid panelGrid = (HtmlPanelGrid)
app.createComponent(HtmlPanelGrid.COMPONENT_TYPE);
panelGrid.setColumns(2);
HtmlGraphicImage image = (HtmlGraphicImage)
app.createComponent(HtmlGraphicImage.COMPONENT_TYPE);
image.setUrl(node.getAttributeValue("imgurl"));
HtmlOutputText outputText = (HtmlOutputText)
app.createComponent(HtmlOutputText.COMPONENT_TYPE);
FacesUtils.setValueBinding(outputText, "value",
node.getAttributeValue("text"));
panelGrid.getChildren().add(image);
panelGrid.getChildren().add(outputText);
// Add the panel Grid component to the
commandNavigation
// component
commandNavigationItem.getChildren().add(panelGrid);
commandNavigationItem.setParent(panelNavigationComponent);
//recursively add child components to the parent
component
addChildComponents(node, commandNavigationItem);
//Add the commandNavigation2 parent component to
the panelNavigation2 component
panelNavigationComponent.getChildren().add(commandNavigationItem);
}
}
this.getChildren().add(panelNavigationComponent);
}
//Method to recursively add child components to
create a multi level left navigation
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
// Exit condition
if (null == parent.getChildren())
return;
List children = parent.getChildren();
Iterator childIter = children.iterator();
while (childIter.hasNext()) {
Element child = (Element) childIter.next();
if ("true".equals(child.getAttributeValue("visible"))) {
HtmlCommandNavigationItem childComponent =
(HtmlCommandNavigationItem)
app.createComponent(HtmlCommandNavigationItem.COMPONENT_TYPE);
childComponent.setId(child.getAttributeValue("id"));
FacesUtils.setAction(childComponent,
child.getAttributeValue("action"));
HtmlOutputText outputText = (HtmlOutputText)
app.createComponent(HtmlOutputText.COMPONENT_TYPE);
FacesUtils.setValueBinding(outputText, "value",
child.getAttributeValue("text"));
childComponent.getChildren().add(outputText);
childComponent.setParent(component);
childComponent.setImmediate(true);
// Add the child component
component.getChildren().add(childComponent);
// recursive call
addChildComponents(child, childComponent);
}
}
In the encodeBegin method of this custom component the
component is constructed programmatically.
In the Renderer for this custom component encodeBegin looks like:
checkState(context, component);
super.encodeChildren(context, component);
//Call encodeChildren on all the child components of this component
List children = component.getChildren();
if (null != children) {
Iterator childIter = children.iterator();
while(childIter.hasNext()) {
UIComponent childComponent =
(UIComponent)childIter.next();
childComponent.encodeChildren(cont
table row within tree2
Hello, I am using Sun JSF 1.1 and Tomahawk 1.1.3 I have a dynamically created table, which is created using c:forEach. Now within this table, and for each row, I would like to add the tree2 functionality. Therefore when a user clicks on a row (the + sign or whatever), this row extends into more rows. Any idea how I can implement this into tree2?

TabbedPane skip validation but not field input values
Hello , I'm quite new to MyFaces/JSF .. I've got a t:panelTabbedPane inside a form with 3 t:panelTabs with several fields on each tab. Being everything included in just one form , submitting the first tab fields causes validation to be fired on required fields on the other two tabs. I tried to set immediate="true" on action commandlink/commandbuttons . This skips validation but I get null values for the fields in action methods.. The solution in posts on this forum seem to be writing an actionlistener to fill bean properties with user input values .. but how ? Any suggestion would be greatly very appreciated Thanks Felice Castelletti -- View this message in context: http://www.nabble.com/TabbedPane-skip-validation-but-not-field-input-values-tf2912864.html#a8138948 Sent from the MyFaces - Users mailing list archive at Nabble.com.

Re: binding / selectOneMenu in dataTable
The selectOneMenu binding object is null. And this is my code:
Here is the dataTable:
cellspacing="0"
columnClasses="defaultCol" headerClass="tableHead"
style="cursor:pointer; vertical-align:top"
rowClasses="zebraTableContentOdd,zebraTableContentEven" rows="20"
value="#{packageLines.packageLineList}"
var="packageLine">
In the dataTable there is a column. As you can see, there is a binding
for the selectOneMenu:
value="#{message['lineAllocation.tableColumn.productionLine']}">
validator="#{packageLine.validateLineSelection}"
value="#{packageLine.selectedLine}"
binding="#{packageLine.oneMenu}">
The selectOneMenu is declared as:
import org.apache.myfaces.component.html.ext.HtmlSelectOneMenu;
private HtmlSelectOneMenu oneMenu;
public HtmlSelectOneMenu getOneMenu() {
return oneMenu;
}
public void setOneMenu(HtmlSelectOneMenu oneMenu) {
this.oneMenu = oneMenu;
}
And heres the validation method:
public void validateLineSelection(FacesContext context, UIComponent
component,
Object value) {
logger.info(getOneMenu());
}
The problem is, that the oneMenu Object is null. I need access to each
SelectOneMenu object of the table, because I have to check the selected
client values.
Any hints what I have done wrong?

But this is always null. So I can't use the
getOneMenu().getLocalValue() method to access the clients value in

Does anybody now what I have done wrong? Or is this a bug in the

I'm having trouble understanding what your setup is. Please post the
