Re: tomahawk tree2 for clay built up tree structure
thx

From: stephan opitz [EMAIL PROTECTED]
problem is the structure.
if i have an object containing an id and a parentId (which is null, or
linking to another object - the parent one)
if i get a list from db how is it possible to build up the structure
for the tree2
i tried hashmap or recursive algorithm, but nothing with much success...
any ideas
You might consider the following code snippet.
public class TreeBacker {
public TreeNode findNode(TreeNode root, Integer sarg) {
Integer id = root.getDescription() == null ? null : new
Integer(root.getDescription());
if (compare(id, sarg) == 0) {
return root;
}
Iterator ci = root.getChildren().iterator();
while (ci.hasNext()) {
TreeNode found = findNode((TreeNode) ci.next(), sarg);
if (found != null)
return found;
}
return null;
}
public TreeNode getTreeData() {
TreeNode root = new TreeNodeBase(root, null, false);
TreeNode current = root; // current root
Collection dbRows = getDBRows();
Iterator di = dbRows.iterator();
while (di.hasNext()) {
MyVO vo = (MyVO) di.next();
Integer id = current.getDescription() == null ? null : new
Integer(current.getDescription());
int order = compare(id, vo.getParent());
if (order != 0) {
current = findNode(root, vo.getParent());
// if current is null you have an orphaned node
}
String type = vo.getParent() == null ? null :
vo.getParent().toString();
String desc = vo.getId() == null ? null : vo.getId().toString();
current.getChildren().add(new TreeNodeBase(type, desc, false));
}
return root;
}
public Collection getDBRows() {
// select parent, id from table order by parent, id
// null, 1
// null, 2
// null, 3
// 1, 4
// 1, 5
// 2, 6
// 2, 7
// 3, 8
// 3, 9
// 9, 10
// 9, 11
Set sortedList = new TreeSet();
sortedList.add(new MyVO(null, new Integer(1)));
sortedList.add(new MyVO(new Integer(1), new Integer(4)));
sortedList.add(new MyVO(new Integer(1), new Integer(5)));
sortedList.add(new MyVO(null, new Integer(2)));
sortedList.add(new MyVO(new Integer(2), new Integer(6)));
sortedList.add(new MyVO(new Integer(2), new Integer(7)));
sortedList.add(new MyVO(null, new Integer(3)));
sortedList.add(new MyVO(new Integer(3), new Integer(8)));
sortedList.add(new MyVO(new Integer(3), new Integer(9)));
sortedList.add(new MyVO(new Integer(9), new Integer(10)));
sortedList.add(new MyVO(new Integer(9), new Integer(11)));
return sortedList;

int order = compare(parent, vo.parent);
if (order == 0)
order = compare(id, vo.id);
return order;
}
}
public static int compare(Integer col1, Integer col2) {
if ((col1 == null) (col2 == null))
return 0;

RE: Is this possible to pass dynamically information from a beans as a shale method parameter?
Some notes. I forget to tell.
It is perfectly working with constans ...
s:validatorVar name=operationID value=Testing/
,not with beans ...
s:validatorVar name=operationID
value=#{mtJobOperation.operationID}/
Second line pass to a custom validator method just a null.

Hello Craig!
Thank you for feedback.
I want to be more specific. I need validate all rows in dataTable
component. JSP page show list of Foo objects. For example, the
inputText component with id=--- has shale custom validate. I need
analyze dependency component id=--- row i from component id=--- row
0...n.
In other words I need pass some current row id to get by id real object.
s:commonsValidator
type=validateQuoteHoursValue
arg=quoteHours
server=true
client=false
s:validatorVar name=operationID
value=#{mtJobOperation.operationID}/
/s:commonsValidator
This valuator does not works. It receive operationID equal null. But
outputText shown some not null information.
t:outputText value=#{mtJobOperation.operationID}/
The Shale validator example show some solution with dynamic shale method
parameter, but it is with standard validator example not a custom
validator.
Alex.

In JSF 1.1, you cannot do this (it's not a Shale issue, it's the basic
functionality of JSF method binding expression). In JSF 1.2, you can
...
but only for calls to static methods.
A better general strategy is to invoke a method that takes no
parameters, but ensure that the called method can extract whatever it
needs. For example, consider the standard JSF call to your action
method (which takes no parameters). There are at least two ways for the
called method to access request parameters on the incoming request:
* Via JSF programmatic APIs:
// Retrieve the value of the foo parameter
FacesContext context = FacesContext.getCurrentInstance();
String foo = (String)
context.getExternalContext().getRequestParameterMap().get(foo0;
* By managed beans expression evaluation. This example requires
a bit more setup to configure, but is much easier to use because
the values are injected for you. Consider again that you want to
extract the value of the foo parameter and use it in your myAction()
action method. Define your managed bean entry like this:
managed-bean
managed-bean-namemybean/managed-bean-name
managed-bean-classcom.mypackage.MyBean/managed-bean-class
managed-bean-scoperequest/managed-bean-scope
managed-property
property-namefoo/property-name
value#{param.foo}/value
/managed-property
/managed-bean
and set up your bean class like this:
package com.mypackage;
public class MyBean {
...
private String foo = null;
public String getFoo() { return this.foo; }
public void setFoo(String foo) { this.foo = foo; }
...
public String myAction() {
// Get the value of the foo request parameter
String foo = getFoo();
...
}
...
}
The formula #{param.foo} is evaluated when the managed bean is created,
and extracts the value of the request parameter named foo and calls
setFoo() on your bean. By the time the action method is called, the
value will be there already.

Re: Custom component with childrens
Assuming you are using JSP, how are using this on your page? With
your own taglib or binding to an existing instance? If you are
simply binding a standard HtmlPanelGrid and then declaring child
components, you will need to bind any nested components as well.

Re: Custom component with childrens
Am playing with jsf and learning ^^ (got example doing new HtmlXXX from
sun's forum)
for the tutorials, if you have good references i'll be happy to read
them, i couldn't find anything that went further than just creating html
elements inside the renderer (nothing about creating composite elements
for example). And i still need a bit of time to read the full 300 pages
jsf specs ^^ :)
Btw am still trying to find how to connect the 'command' to the bean
'someAction' method, because the bean is the result of evaluation of my
custom component 'value' and i bet if my custom component is invoked
like this
customLib:customComponent value=#{myBean.myProperty}/ and i try to
generate a method binding for command action using such an expression
'#{#{myBean.myProperty}.someAction}' this will probably fail :)
Thanks for your time,
David Delbecq
James Mitchell a écrit :
I see, sorry I wasn't paying attention to your constructor.
Try creating your components with something like this...
...
...
street = createHtmlInputText(street);
number = createHtmlInputText(number);
town = createHtmlInputText(town);
postCode = createHtmlInputText(postCode);
command = createHtmlCommandButton(command);
...
...
}
protected HtmlInputText createHtmlInputText(String id) {
Application application = FacesContext.getCurrentInstance
().getApplication();
HtmlInputText intput =
(HtmlInputText)application.createComponent
(HtmlInputText.COMPONENT_TYPE);
input.setId(id);
return input;
}
protected HtmlInputText createHtmlCommandButton(String id) {
Application application = FacesContext.getCurrentInstance
().getApplication();
...
...
The problem is in how you are creating new components. It isn't
enough just to do new HtmlXXX(), you must create them with the
createComponent method. There's a few things going on under the
covers with respect to how JSF deals with components. You might also
think about getting a good book or referencing a tutorial while
building your app. There's a lot more to JSF than meets the eye.
