Tree Component AS3 Error

When I click a leaf in the Tree Component I have a function
called using the itemClick Property. When I click a node (the
folder icons) I get the AS3 error below. Does this only show up
with Debug versions of Flash Player. Plus how do I stop this error
from occurring if the user happens to have the debug version
installed?

ORA-00600 internal errors should be reported to Oracle Support by SR. If you don't have a support contract try searching the web for more information and possible fixes or workarounds.
From the information available on MOS, if the type of the PG.ID_PAR_PLANO_GER column is not VARCHAR2, then try converting P22_ID_PAR_PLANO_GER to the same type.

well i never liked XML and before i worked with tree component
directly and no problem but now , Flex force me to work with XML or
API(well I don’t know what dose it mean ) and I was tiring to
find any way to get directly to tree component in Flex2 and no
result … so my question , do I have use XML ? Is there any

and I find the help content is really bad . pleas help , I get
crazy about this problem …….
BWY this form work terrible on my PC ….. anyone have

Use xml. Resistance is futile.

Why no Tree component for AS3?

Why is there no Tree component when working with an AS3 based

Hi i have the same problem, Did you found a solution ?

Garbage Collection Issue for Tree Component

Dear:
When I created a new Tree instance dynamically by following code, and clicked any tree node randomly and then I removed it via another button, but I found this instance couldn’t be removed by GC, if I just created this tree without mouse action, it can be removed by GC.
Tree Component:
-- TreeView
<mx:canvas>
<mx:Tree dataProvider="{data}" />   // data is a XML staments
</mx:canvas>
Create Tree:
           public function createView(event:Event):void{
              var view:TreeView = new TreeView ();
              view.name="myTree";
              addChild(view);
              view=null;
Remove Tree:
           public function deleteView(event:Event):void{
              var view:TreeView= TreeView( _con.getChildByName("myTree"));
              removeChild(view);
Could someone give me some suggestion?
Thanks a lot

Hi ajmcfarlane,
This is my first post here. I'm fairly new to AS3 still and
have been getting my education from a number of places. The best
education i have found is from the book located at
http://www.learningactionscript3.com/
Rich Shupe address this problem of removing the child from
memory. I Downloaded your file and found 2 problems and resolved
one of them. By now you might have already solved this anyway.
To remove the child from the Display List use -->
removeChild(myChildObject);
To remove the object from memory use --> myChildObject =
null;
You did these two steps but in the incorrect order, just by
moving the 'myChildObject = null' under the removeChild code makes
it work.
I found running a few trace statements after fixing the first
problem, i found the second problem. The error of trying to remove
a child when it is no longer there.
You just need to rework the design so that the order of
events fires as you want. Below is the traces i used and the output
that is received.
function Click1(e:MouseEvent){
trace("four ", loadedcontent);
modLoader.unload();
modLoader = null;
function unloadCompleteHandler(event:Event):void{
trace("one ", loadedcontent);
removeChild(loadedcontent);
trace("two ", loadedcontent);
loadedcontent = null;
trace("three ", loadedcontent);
output
Loaded mem: 20668 KB
four [object MainTimeline]
one [object MainTimeline]
two [object MainTimeline]
three null
unLoaded mem: 23352 KB
So you can see the click event is firing of the unload first,
when i think you want that last.
I hope this has been of some help :)

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 as swf

I have a swf file that is a Tree Component... (So when it
diplays it looks like a Directory structure with folders and files)
Some nodes access url links... And some access .doc files on
the network... This works fine when I run it from my local site,
but when I run it on the remote site (Intranet server) the nodes
that reference file paths so nothing, instead of opening the file,
the url type links do work fine on the remote site.
Any thoughts on why this might be occurring ? I am putting
the swf and the associated xml file and html page on the remote
site... Am I missing a file or setting on the server that I have
locally? I am also including my .as file and xml file for review.
Any help would be greatly appeciated.

This does work fine locally... But the file paths node do not
work when I publish to the Intranet server.

It is quite a pain in the rear to skin the AS2 components.
And I don't know of many 3rd party components for AS2. I know of
plenty AS3 3rd party components, but if you were using AS3
components you wouldn't need a Tree to replicate the adobe video
workshop type navigation, all you would need is the built in List
component. If you can go sans icons, I would suggest using the AS2
List to get the feel you're looking for.

Tree component in Sun Studio Creator

Hello.
I have a problem with Tree component in Sun Java Studio Creator when i use it.
Error:

Please, tell me, how to use this component?
Thank you.

java.net.MalformedURLException: no protocol:
/layout/layout.dtdDid you ever bother to read the error message? It tells you what's wrong, and it tells you how to fix it.
"/layout/layout.dtd" is not a valid URL. Fix that.

Tree component bug

We use a tree component on client side with several tree nodes.
We have a tree action for them.
It usually works fine, but randomly getCookieSelectedTreeNode() method returns null (empty string). Sometimes no error after 10 clicks, but sometimes it returns null after a few click.
If somebody have a solution for this, please let us know.

I have a solution for my problem now. It turns out that my issue wasn't quite the same as the original problem cited by K_Gabor.
Our issue was machine specific and was down to the fact that getCookieSelectedTreeNode() will return null if cookies are blocked by the browser. Not really surprising given the name of the method, but it is something that should be kept in mind when using this method.
Given that cookies are frequently blocked, is there an alternative method for getting the selected node that doesn't rely on cookies?
Cheers,
Chris.

Issue with af:tree component

Hi All,
I am using JDev 11.1.1.6
I am creating a tree component with collection model.I want to provide different action to each node,so I have defined an action attribute in the bean
which I set in the constructor as shown below
TestTree node1 = new TestTree("node1", "#{TreeBean.action1}");
Is this the correct approach..This gives me "method not found " error when I click on the node.
Below is the code for tree component :
<af:tree value="#{TreeBean.model}" id="t1" var="node"
styleClass="AFStretchWidth" inlineStyle="height:600.0px;">
<f:facet name="nodeStamp">
<af:commandLink text="#{node.label}" id="cl1" immediate="true"
actionListener="#{node.action}"/>
</f:facet>
<f:facet name="pathStamp"/>
</af:tree>

Hi,
I am trying to render myfaces client tree on faces portlet using RAD 6.0. As RAD does not support JSF 1.1, I have commented DOCTYPE from faces-config.xml in tomahawk.jar file.

Unable to implement Programmatic ADF Faces Tree component in jdev 11g

I have referred to the posts " [Back to programming: Programmatic ADF Faces Tree component|http://one-size-doesnt-fit-all.blogspot.com/2007/05/back-to-programming-programmatic-adf.html] " and " [Follow-up: Programmatic ADF Faces Tree in JDev 11g|http://one-size-doesnt-fit-all.blogspot.com/2007/05/follow-up-programmatic-adf-faces-tree.html] ",
The first post showed how to construct the elements in the tree programmatically rather than relying on bindings (in JDeveloper 10.1.3)
and the second post tells the only difference in 11g .
I am trying to implement the elements of the tree programatically in Jdev 11g(specifically 11.1.1.0.2) but no result is coming .
There is no compilation/run time error , its just that the tree is not visible.
Can anyone suggest any key points which should be focussed during this implementation?

Hi,
follow the description
http://www.oracle.com/technology/products/adf/adffaces/11/doc/demo/adf_faces_rc_demo.html
to install the ADF Faces RC component demo in JDeveloper. It has a tree example. Have a look at their implementation and dapt it to your needs

Bug in Tree Component

Hi All,
I am facing a problem in the dynamic tree which i created. I had created actionhandler for tree leaf node and actionListener for collapsible nodes but in a particluar case where the user first clicks a tree leaf node and after the tree is reloaded from the server if the user next clicks the collapsible node the actionhandler is invoked instead of actionListener and an execption is thrown which i have pasted below. It seems to me like this is happening because the focus is still on leaf node when the user clicks the collapsible node as the tree uses cookies to track the selected node. It seems like a bug in tree component. Does anybody knows any workaround for this

Customizing the Tree Component

Is there a way to set different font sizes and colors for
different levels of the tree menu?

I am guessing that you are using AS2 components, as there is
not a default Tree component for AS3...
I don't know about font sizes, but you can set depth colors
for the AS2 Tree.
The following will set the background colors to black, medium
grey, lighter grey for the Tree that is named "myTree":
var colorArray:Array = new Array();
colorArray.push(0x000000);
colorArray.push(0x555555);
colorArray.push(0x999999);
myTree.setStyle( "depthColors", colorArray );
Note that this is based on the depth. IE for the node
structure:
<node label="First Level">
<node label="Second Level">
<node label="Third Level">
</node>
</node>
</node>
First Level with have a black background, Second Level will
have a medium grey background and Third Level will have a lighter
grey background.
