Trouble with Frank Nimph Building a hierarchical tree from recursive table
I copy the example, but when i run it i get the error:
javax.faces.el.EvaluationException: javax.faces.FacesException: javax.faces.FacesException: Can't instantiate class: 'vuo.view.TreeHandler'.. class vuo.view.TreeHandler : java.lang.ClassCastException: oracle.jbo.domain.Number
Caused by: java.lang.ClassCastException: oracle.jbo.domain.Number at vuo.view.TreeHandler.populateTreeNodes(TreeHandler.java:58)
This is line 58 of TreeHandler.java : employeeNode.setEmployee_id((Number)row.getAttribute("EmployeeId"));
The problem is that i couldn't import oracle.jbo.domain.Number; like in the files TreeHandler.java and GenericTreeNode.java because when i type import oracle.jbo.domain.Number;on my java classes It doesn't compile, in GenericTreeNode does not recongnize:
private Number employee_id;
private Number manager_id;
private Number salary;
and in TreeHandler it said Number not found.
So i comment the import oracle.jbo.domain.Number; on both classes and compile ok, but when i run the page i get the error:
javax.faces.el.EvaluationException: javax.faces.FacesException: javax.faces.FacesException: Can't instantiate class: 'vuo.view.TreeHandler'.. class vuo.view.TreeHandler : java.lang.ClassCastException: oracle.jbo.domain.Number
So what can i do?
Thanks.
Hi,
as you copied the code, male sure that your classes import statement has oracle.jbo.Number and not java.lang.Number in it. It seems that you try to cast oracle.jbo.Number to java.lang.Number. Note that oracle.jbo.Number requires the ADF Business Component runtime libraries to be selected for the ViewLayer project (see project libraries)

Problem with Pre-Popup-Menu in Hierarchical Tree
Hi,
In Forms 10g I have made an application with an Hierarchical Tree. All works well, except the use of the Pre-Popup-Menu trigger.
In that trigger when I read the values of Node_Label and Node_Value I get the values of the previous selected node, not the values of the node on which I issue the right mouse click. So, it seems that by clicking the node I need is not selected.
Does anyone have any clues to solve this problem?
Thanks in advance.Right clicking does not change the current selection. The tree has no way to report what node was right clicked. Only work around is to left click the node you wish then right click it.

Can I use Hierarchical Tree from Forms6.0 in Forms5.0
Hello
The Oracle Custumer Support tell me that it should be possible to
use Hierarchical Trees also in Forms5.0
I look for a possibility to build a Navigator in Forms5.0
with Symbols. (look and feel like the Navigator in Forms6.0 if I
use Symbols in the Record Group).
I Description should be on
http://developer.us.oracle.com
but either i have no access to this side or
the URL is false.
Sure is that there is a description over this Problem.
And i have to get this description ;-)))
Thanks for Help

nullThat is not recommended. The new code editing features do not play well with an old workspace.
Please create a new workspace and import your projects into that.

Building a binary tree from a string
I'm having trouble building a binary tree with shape described in a string.
00 - means both left and right subtrees are empty;
01 - means that the left is empty, and the right is not;
10 - right is empty, left is not
11 - neither are empty
public BinaryTree(String s, Iterator it) {
This constructor is supposed to build the binary tree of the specified shape and fills it with values. THe values come from Iterator it, and are placed into the tree in preorder fashion.
I have to complete this constructor but I don't really know what to do. I was thinking I could use indexOf somehow. Any help would be greatly appreciated.
Thanks,
MikeI'd build it like this (this is from the top of my head, so no typo-free-warranties etc.) -- public class Tree {
private Object data;
private Tree left= null;
private Tree right= null;
private Tree(StringReader sr, Iterator di) {
char l= (char)sr.read(); // left and right subtree indicators
char r= (char)sr.read();
data= di.next(); // set data for this node
if (l == '1') left= new Tree(sr, di); // build left subtree
if (r == '1') right= new Tree(sr, di); // build right subtree
public Tree(String s, Iterator di) {
this(new StringReader(s), di);
} Note that the private constructor (the one that does all the work) doesn't handle incorrect strings
at all, i.e. it'll crash horribly when the string passes contains, say an odd number of characters
is is simply passing incorrect construction information. Also note that the Iterator must be able
to iterate over enough elements to be set.
kind regards,

I'm having trouble with ABS kernel build
I built a kernel, as per https://wiki.archlinux.org/index.php/Cu … n_with_ABS . It seemed pretty straight forward.
The goal was to set CONFIG_PREEMPT=n so I could compile and native install ZFS. I managed to get the kernel compiled and installed with the modification.
Now, when I run configure on the SPL, I get the following error:
checking kernel source version... Not found
configure: error: *** Cannot find UTS_RELEASE definition.
It looks like I've done something wrong on the kernel build but I don't know what.I'm sorry I didn't see this before, but anyway I'm leaving this here in case someone else finds this through a search.
I encountered this error while configuring spl as well, though I had not built my own kernel. The definitions are provided by the kernel26-headers package.
For those interested in trying out zfs, there is as of 2011-05-31 an issue with zfs-0.6.0-rc4 + the Archlinux kernel (2.6.37 and 2.6.38 confirmed), that causes a deadlock when writing to a zfs pool, effectively making zfs unusable. There seems to be a way of configuring oneself out of this by recompiling the kernel. I shall update if I manage to get it to work.
More info here: https://github.com/behlendorf/zfs/issues/167 -
Build a hierarchical structure from a ordered table
Hi guys,
say I have a table A with 3 columns, each column represents a level in a hierarchical structure. Is it possible to make a recursive query (connect by) to retrieve the info in a hierarchically way?
TABLE A.
COL1 COL2 COL3
1 2 3
1 2 4
1 2 5
The tree I want should be something like:
1
2
3
4
5
Thanks for your help!.Not really, there was a display problem. What happen is that I want to display a tree in Forms based on the info I have in my table, so the tree(implemented with FTREE) has to look like this:
+1
--+2
----3
----4
----5
As you can see, if the table would be with only 2 columns with an pig ear relationship this would be very easy, however my hierarchy of my table is based on the position of the columns:
COL1 father of COL2
COL2 father of COL3
and so on...
My problem is that I don4t know how the query I have to fill in the Data Query property of my tree has to be.
I tried on Forms forum but didn't get any answer, so I hope you sql guys may give a clue, as I know you're very smart in this area.
Thanks for your sooner input.! -
Troubles with opening Finder, System Preferences, and others from dock
I am having problems with Finder, System Preferences, applications like Word, Excel, and Firefox. When I click on their icons in the dock, the menu bar appears with the name of the application and file, edit, etc. but the application does not open a window on the screen. I just see my background pic. Some of the items in the menu bar that pop down don't work. However, apps like my mail, Safari, Itunes and others work properly.
If anyone can help me with some suggestions, that would be great!
tannikcaHello t:
Welcome to Apple discussions.
Do those applications open from the application folder? If they do:
Try trashing a preference file and restarting (com.apple.dock.plist).
If that does not help, drag the icons that do not work off the dock (poof sound). Then go to the application folder and drag the appropriate icon to the dock.

Displaying data in a tree from database table
Hi,
I want to display data from a database table (mara-matnr) in a tree structure. I went through the coding of SBSPEXT_HTMLB. There static data was taken in to wa_tab. But there I want to bring data from a database table into wa_tab. For this I created an internal table without headerline by taking a work area, now how can I move data from this work area to wa_tab record by record.
I hope some one might have worked on this. Plz help me....
Thanks in advance,
Ravindra.Hi,
take a look at this <a href="/people/tomas.altman/blog/2004/12/13/sdn-blog-how-to-do-internal-tables-in-bsp which explains how internal tables work in ABAP OO.
Furthermore I think you want to do this:
insert <yourWorkarea> into table wa_tab.
A complete mara example would be:
data tab_mara type table of mara.
data wa_mara type mara.
select * from mara into table tab_mara.
*or you can use:
select * from mara into wa_mara.
insert wa_mara into table tab_mara.
endselect.

URGENT *** Hierarchical Tree in Forms 9i *** URGENT
Hello everybody,
for my company I need to build a hierarchical tree item, that will display static data over three levels. Let's say: departments, employees and employee projects.
How do I fill the Item?
When do I fill the Item?
Where do I fill the Item?
What are the elements of the SQL query, that fills the hierarchical tree?
Any help will be appreciated
[email protected]Note:210663.1 helped a bit.
I used the database column as the third element in the select part and put NULL as the fifth element. Then it worked.
Now I am looking for the way to add the employees, when the user selects / activates a department node. -
Finding proper help on Hierarchical Trees
Have spent a couple of hours trying to navigate the sprawling website of oracle.com with the purpose finding and then downloading the appropriate help file. I downloaded
Oracle9i Developer Suite Release 2 Documentation Library
from
http://www.oracle.com/technology/documentation/ids.html
Its about 130Mb, installed it, but could i find comprehensive documentation on using Forms 9i (in particular Hierarchical Trees) no, but everything else it seemed yes. The original doc that pre-installed with the 9i DS 'online help' is reasonably helpful but like some others on this forum I could not find proper help on how to use Hierarchical Trees all i could find was few descriptive portions of text and believe me i have looked.
Others have said they found examples of Hierarchical Trees usage i can only assume they are using 10g. So this is a desperate plea to you. Can you point me to an online resource that deals with Hierarchical Trees in Forms 9i (intro, usage, examples, etc). If you can i would deeply appreciate it.
Mr Frustrated :)Hi,
You have a lot of sample With the Forms Help.
If you search in the index with "htree."
The command hierarchical tree complete list appear.
