Transparency in Tree component and actions in its sheets

Hello people
I'm doing a kind of catalog, and I'm using a component "tree" for listing.
But here's the problem: I need to use the background I have in the scene, and the component has a white background I need to remove. The workaround I've found is to give 0 _alpha property to the instance of the tree I have in the scene, but it also hides its icons, and I need those visible.
The other thing is that I need that when you run over a leaf, multimedia displays a small view of an image, and when you click-go to a specific frame where I have the large image with description.
If anyone knows how can help me I would be greatly appreciated.
I searched the online help that Adobe is now, and I found these properties of the tree but there is no way to work (at least I need):
themeColor
backgroundColor
backgroundDisabledColor
depthColors
borderStyle
color
disabledColor
embedFonts
Thanks in advance.
P.S: Sorry my bad english

Use xml. Resistance is futile.

Tree component event action

Hello
There's a page which contains the following 3 components: Input textfield, Button, Tree
I made the following settings of them:
I set the "event action" at the tree node, and so did I at the button properties.
When I click on the button, the action runs and set the value of the Input textfield:
�this.i_textField1.setValue("something");� - the Input textfield display it as it should.
When I click on the tree node and the event action runs (it can be tracked in debug mode) which runs �this.i_textField1.setValue('something');�, but the textfield doesn't display it.
Any suggestions?
Thanks

The root problem is that the tree node component always behaves as though it had an immediate property set to "true". You'll get the same behavior from button or hyperlink or any other action component is you set immediate="true". The text field submitted values are not cleared, and so the text field redisplays them instead of the value that is set in code or obtained by evaluating the binding on the session bean.
There is a work-around. There is a page bean method, erase(), which will clear all submitted values. Call this before you set the new values, e.g.:
    public String treeNode1_action() {
        this.erase();
     textField2.setValue("Tree Node");
        staticText2.setValue("Tree Node");
     getSessionBean1().setTemp("Tree Node");
        return null;

Tree component and loading xml files into text field

Hello and thank you for taking the time to read my issue....
I am making a simple self help application. I have a tree component that loads the different catagories and topics for my help app dynamically via an xml file...no issues there.
I then want it so that when the user cliecks on the actual topic that the TextArea component will load the info from another xml file using the name of the topic as the name of the xml file to make it that much easier for anyone to maintain this program.
So far the code i have is this.
myTreeListener.change = function(eventObject)
    var theSelectedNode = eventObject.target.selectedNode;
    var theSelectedNodeLabel = theSelectedNode.attributes.label;
    topicTextArea.text +=
I am a little fuzzy when it comes to loading the xml file in. Should i be loading html instead of xml is my other question as well?
Thanks in advance for your help

Check out the Oracle XDB Developer's Guide, Chapter 3. There is an example of using BFileName function to load the xml files from a directory object created using create or replace directory. It works really well.

Transient form component and action listener

Hi,
I am binding a transient component to my h:form and wonder why my action listener is not called when update the form. Could someone give me a hint if this is possible? Are transient forms ignoring action listeners? Can some one give my a short example?
Maciek

The actionlistener can do whatever you want. Not sure what you need exactly but it might be better idea to create some Action classes and use them on each button:

Java implementatino for AND-OR trees. And also for its visualization?

Hi,
I need to have an implementation of an AND-OR tree, that is, a tree in which the children of a node can either be conjunctive or disjunctive (normally the parent is consider an AND-node or an OR-node). The reason is that I need to represent Prolog rules in a java structure (not simply as a string). Do you know of any public implementation of such a structure?
In addition, do you know of any existing visualization package or implementation that represents such a structure?
Thank you in advance.

Contact the sales departments of the manufacturers (Giesecke&Devrient (G&D) and Oberthur, and maybe also NXP). They will refer you to the distributor/reseller for your area, through whom you can establish an NDA with the manufacturer and get access to the specification documents.

But the problem is that it publishes [type Function] in the
tree.
no actual xml nodes are visible, just bunch of [type
Function]
ive also searched for info / tutorial how to publish actual
xml data in the tree component but without any luck.
So what should i do and how ?

ADF Tree Component Iterating through all nodes upon ONE node click...

Hi to all !. My name is Agustin and I live far away... In Cordoba Argentina to be specific !. My doubt would be the following one: I wanted the other day to build a af:tree component and put in the NodeStamp an commandLink with a setActionListener... So as to get the selected Node... In this case, I have category of books... Let say DataBase, Cloud Computing, Web Development and so on... But the misterious thing happens when I click on one node, and the action method in my backing bean is executed one time per each node the Tree has... I notices this coz I made a System.out.println()... My idea would be to detect the user click event so as to update a Table... My code is as follows !...
<af:tree value="#{backManager.listaCategoria}" var="cat"
binding="#{backManager.tree1}" id="tree1">
<f:facet name="nodeStamp">
<h:commandLink binding="#{backManager.outputText1}" action="#{backManager.outputText1_action}" >
<af:setActionListener from="#{cat}" to="#{backManager.selectedItem}" />
<h:outputText value="#{cat.label}"
binding="#{backManager.outputText2}"
id="outputText2"/>
</h:commandLink>
</f:facet>
</af:tree>
and my backing bean is:
public String ejecutarSeleccion()
Categoria cat = (Categoria) this.selectedItem.getValue();
System.out.println("Nombre: " + cat.getNombre());
return null;
This method is the action attribute from the command link !.
the selectedItem is an attribute of the type SelectItem !.
Where I would be making the mistake ?... Or should I implement the thing in a different way ?... Thankx ! :D

Hi,
its strange when you say it executes the action per each node in the tree. One thing tough I would change is to go from h:commandLink to af:commandLink as it allows you to set partialSubmit=true in which case a click on the tree doesn't refresh the whole tree. I then would add an f:attribute tag to the command link
<f:attribute name="cat" value="#{cat.id}"/>
On the command link I had the actionListener property pointing to a managed bean with a method like
public void onTreeNodeAction(ActioneEvent actionEvent){
RichCommandLink link = (RichCommandLink ) actionEvent.getUIComponent();
Object catId = link.getAttributes().get("cat");
// ... cast the catalog id to its type and you are ready to go
Another option would be to use the SelectListener of the tree and don't use a command link at all. You respond to tree node selection similar to here

Tree Component ... getting crazy !

So tree component is terrible , every thing is gone , trying
all day to get directly to tree component and no result ,and there
is no basic explanation and no examples , i tried to search in Flex
Help Content , but I get more Cold Fusion tree help than Flex tree
.. spend 800 dollar for flex and get CFHelp , I don’t think
is good idea , so pleas help me , how can i add simple tree node
with out XML , I hate XML , and i know some how we can work with
Tree component directly though ITreeDataDescriptor , but how ..?
In As2 it was simple and easy, now how to do this I
don’t know and I am not only one!
I am not a specialist in Action Script but in AS2 I never had
a problem, and if I did, we have a lot of documentation about AS2
and examples, but Flex trying to sell a product that not supports
any examples and documentation... Write in search content
‘tree’ and you get cf tree examples and structures, but
I don’t need cftree information, I need flex tree exemplas,
but there is few... Working with flex all week I get more tired and
depressed.. Any thing I trying to do is going wrong, AS2 is not
there any more and I understand that I have to learn AS3 from
beginning to understand it... I hate it!!!!!!
Flex - Rich Application for users and Rich work for
Developers!

Eddy, chill out man.
How can you say, "I hate XML," and really even try to learn
Flex? Flex is based on XML, MXML is XML, any services you call
(HTTP or WEB) are XML. I think it's time for change and time you
picked up XML. It's actually very, very simple.
You don't have to learn AS3 from the ground up. There are a
lot of similarities between AS2 and AS3.
You just need to write a simple function which goes through
the array and converts it to xml. While I could program that for
you, I think you could probably figure it out yourself.
But why even bother? Using an XMLList is just as easy.
Behold:
<mx:XMLList id="treeData">
<node label="Mail Box">
<node label="Inbox">
<node label="Marketing"/>
<node label="Product Management"/>
<node label="Personal"/>
</node>
<node label="Outbox">
<node label="Professional"/>
<node label="Personal"/>
</node>
<node label="Spam"/>
<node label="Sent"/>
</node>
</mx:XMLList>
XML is composed of parents and children. You can do much more
with XML than you can with plain old arrays, plus, when's the last
time you saw a 10-tiered multi-dimensional array? It's not possible
to do something like that without XML.
Over and out - Taka.

Tree component index confusion

Hello,
I have a Tree component and need to access some nodes by its
index. This is to make a "move up/down" control. My idea, after
trying many, is to duplicate the selected (current) node up or
down, then replace the content of the original with the previous
node content.
I wish not to use previousSibling or nextSibling since, as it
seems, it doesn't recognizes either the origin and destination
nodes are in the same hierarchical level.
Working with some
index function doesn't works as I would expect when in 2nd
level nodes (that is, some child nodes of the first nodes) ; for
example:
-- node (index 1)
-- node (index 2)
-- child (index 3)
-- child (index 4)
-- node (index 5)
if the selected node is the second child of the second node,
index = 4, and then I substract this number to get the (supposedly)
previous child,, that is, in index 3, then I get the node in index
5.... my thought is that, when closed, the node in index 5 was
actually index 3.
Any clarification on how this could be happening is greatly
appreciated. Thanks,
Alvaro Medina

I also need to get a exact position in the nodes for a
selected item, such as in the following format
getTreeNodeAt(0).getTreeNodeAt(5)
in order to delete certain folders
thisTree.getTreeNodeAt(0).getTreeNodeAt(5).removeTreeAt(2)
How can I do this?? All i can get so far is node object by
thisTree.selectedNode ...

Customizing the Tree Component inn ADF Faces..

HI,
I am using the ADF Faces Tree Component and was wondering wheteher we
can use a specific theme instead of the default one..
The scenario's i am looking at are
1) Changing the Style of the Selected Node
2) Programatically can i assign a different styling for a Specific
Node (Previously Selected) in the Tree ??
3) And any info reg Enabling the Drag and Drop functionality ?? As of
now i don't think it is supported. Are there any plans of it being
supported in the furture releases??
Thanks
Sateesh

Hi,
1) See tree skin selectors: http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/skin-selectors.html
2) You can reference a managed bean for providing the inline style sheet on a component. This however only works when the tree is re-drawn and not dynamically
3) Drag and drop doesn't work in 10.1.3.x. In 11 this may work - havent tested yet - using a client listener component

JSF tree view GUI component and tree node actions

Hi,
I am new in using JSF and have a problem with my simple test application.
The application contains a tree view control with one static tree node and a separate text area. Clicking on the tree node shall fill the text area with the string 'hello'. Seems to be very simple, but it doesn't work.
What did I do?
First of all I use the Sun Java Studio Creator 2.
By double clicking on the tree node in the design window of the IDE a method called treeNode1_action() was created. I also added the String text to the session bean. treeNode1_Action() does not more than setting text='hello' ( getSessionBean().setText('hello'); ).
The jsp file contains the line
<ui:textArea binding="#{Page1.textArea}" id="textArea" style="height: 192px; left: 360px; top: 48px; position: absolute; width: 456px" text="#{SessionBean1.text}"/>, so the text of the text area is bound to the session property 'text'.
Running the application and clicking on the tree node does nothing except reloading the page (no 'hello' inside the text area).
Using the debugger showed me that the bean property text is set correctly to 'hello', also after reloading the page.
What did I do wrong?
What do I have to do to display 'hello' in the text area?
I would be glad for some good advice to solve my problem and looking forward for an answer.
Regards from germany
Matthias

want to remove the green patch from the jsf tree componentas u said ,, it is COMPONENET so this is a pre-made creator component that u cant chnage its attributes ,,
instead u can extract Theam.jar file and change the icons ,, u i didnt do it before ,, but u may be find what u want there,
hope this will help
good luck

Tree component transparent background

Trying to make the tree component have transparent
background.
I have tried puting it in a movie clip and making that Alpa =
0 but that makes the scroll bar and node icons disappear.
Is there a actionscript genius out there that would be kind
enough to help an aspiring flash junkie out?
Thanks in advance.

I just did the same myself and it became transparent....
import mx.styles.CSSStyleDeclaration;
if(_global.styles.Tree==undefined){
_global.styles.Tree=new CSSStyleDeclaration();
_global.styles.Tree.setStyle("backgroundColor","undefined");
however - after i did this, i lost the possibility to click
on the items in the tree - i could move with the up and down arrows
but thatds not the point so can anyone help me out here
please?

Issue with Drag&Drop between table and tree component

I want to drag table rows and drop it on the tree node. I use following code to achieve this:
<af:table value="#{bindings.pricingObjects.collectionModel}"
var="row"
rows="#{bindings.pricingObjects.rangeSize}"
emptyText="#{bindings.pricingObjects.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.pricingObjects.rangeSize}"
selectionListener="#{workspaceBean.onTableSelect}"
rowBandingInterval="0" id="poTable"
partialTriggers=":::csTree :::cbRefresh"
columnStretching="column:c4"
displayRow="selected"
contentDelivery="immediate"
clientComponent="true"
binding="#{workspaceBean.table}"
rowSelection="multiple">
<af:dragSource actions="MOVE" defaultAction="MOVE" discriminant="rowmove"/>
</af:table>
<af:tree value="#{bindings.privateChangeSets.treeModel}"
var="node" displayRow="selected"
selectionListener="#{workspaceBean.onTreeSelect}"
rowSelection="single" id="csTree"
expandAllEnabled="false"
binding="#{workspaceBean.tree}">
<af:dropTarget dropListener="#{workspaceBean.dropListener}" actions="MOVE">
<af:dataFlavor flavorClass="org.apache.myfaces.trinidad.model.RowKeySet"
discriminant="rowmove"/>
</af:dropTarget>
</af:tree>
With this code I am getting the data of dragged rows but I am not able to get the tree node where rows are dropped. Dropevent.getDropSite() always returns NULL.
Strangely, I tried to use deprecated tags <af:collectionDragSource> and <af:collectionDropTarget> and everything works fine. Dropevent.getDropSite() returns me the correct rowkey of tree node.
Any idea why am I not getting desired result with <af:dropTarget>?

Hi,
+" Please note that dropSite==null is a legal value for collection components. dropSite=null and DropOrientation==ON indicates that the drop has happened outside the data portion of the collection component and should be treated as a drop on the entire component Also note that dropSite==null and DropOrientation==AFTER indicates that the drop has happened on an empty collection component and the user intends to append the data."+
http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e10684/oracle/adf/view/rich/event/DropEvent.html#getDropSite__
List dropRowKey = (List) dropEvent.getDropSite();
        //if no dropsite then drop area was not a data area
        if(dropRowKey == null){
            return DnDAction.NONE;
        }Frank
