Question on removing a child node in a tree component - JSF

When I m trying to delete a child node in a tree component the focus is not transfering to the parent node. I m using the setselected method to set the focus to the current node but not sure how to transfer the focus to parent node once I delete a child node. Please advice.

Programmatic, using bean add Parent and child nodes in af:tree dynamically

Hi All,
i have to add parent and child nodes dynamically in tree .
Example :
i have created a tree like below.On click of button i will get value A ,from pl/sql function i will A1 and A 2 values.which i have to show in pop as tree.
A
|-----A1
|-----A2
If user clicks on A2.I have to catch A2 value and pass to pl/sql function which gives A2.01 and A2.02 values.
A
|-----A1
|-----A2
|------A2.01
|------A2.02.

How to add a button in the child node of the Tree Table?

Hi All,
I am having a requirement to create a tree table and it should have a delete button to each child node (screenshot attached).
Can anyone provide me a sample for how to implement this.
Thanks in Advance

Hi Aravindhan,
Try something like this:
var ttDesvios = new sap.ui.table.TreeTable();
var cbDesviacion = new sap.ui.commons.CheckBox();
ttDesvios.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Col1"}),
template: new sap.ui.commons.Label({text: "Info"}),
width: "50px",
ttDesvios.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Action"}),
template: new sap.ui.commons.Button({text: "Delete"}).bindProperty("visible", "pathPropertyChild", function(value){
if(value .............){ return true;} //For child
else{ return false;} //For parent
width: "160px",

Problem when selecting child node in Hierarchical Tree

I have a hierarchical tree on a form populated thru a table query(form1). When I click on a child node, it opens form2 which contains a tab canvas. After closing forms, I return to the form1(containing Tree). At this point If I want to click on the same child node, I should be able to open form2 again. This doesn't happen.
I have the following code in my When-Tree-node_selected trigger:
Declare
htree item;
vnode_label varchar2(50);
node_clicked FTREE.NODE;
vnode_value number;
vnode_depth number;
v_type number;
v_value varchar2(100);
v_form_name varchar2(100);
v_alert_return number;
begin
-- Find the tree itself.
htree := FIND_ITEM('tree_block.tree');
node_clicked := :SYSTEM.TRIGGER_NODE;
vnode_value := FTREE.NODE_label;
-- Find the value of the node clicked on.
vnode_label := FTREE.GET_TREE_NODE_PROPERTY (htree,:SYSTEM.TRIGGER_NODE,FTREE.NODE_label);
vnode_depth := to_number(ftree.get_tree_node_property(htree,:SYSTEM.TRIGGER_NODE,ftree.Node_depth));
--Open form for node selected on tree and/or specific tab page
if vnode_depth <> 1 then
if :system.trigger_node_selected = 'TRUE' then CASE vnode_label

if id_null(Find_form(v_form_name)) then
open_form(:global.application_path || v_form_name,ACTIVATE,NO_SESSION,SHARE_LIBRARY_DATA);
else
go_form(v_form_name);
end if;
END IF;
elsif vnode_depth = 1 then
if :system.trigger_node_SELECTED = 'TRUE' then CASE vnode_label
WHEN 'EMPLOYEE INFO' then
v_form_name :='HR_PERSONAL_INFO_UPDATE';
vnode_label := 'Personal';
WHEN 'REPORTS' then
v_form_name :='HR_REPORTS';
vnode_label := '';
if id_null(Find_form(v_form_name)) then
v_form_name := :global.application_path || v_form_name;
open_form(v_form_name,ACTIVATE,NO_SESSION,SHARE_LIBRARY_DATA);--,p_list);
else
go_form(v_form_name);
end if;
end if;
end;
Can anyone please help me? I don't want the user to double click. They should only click once.
Thanks,

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.

Deleting Child Node in a Tree

Hello,
I have a tabbed screen.
On one of the screen, I have used a container and the container is displaying my data in a tree format.
There could be 1 to N child node.
Now my requirement is to delete one or more of these nodes.
Any idea how do I proceed?
Thanks in advance.

Use the method delete_node passing the node_key parameter

Hi all,
Relatively simple table
create table replaced_parts
old_part_number varchar(7),
replaced_part_number varchar(7),
updated_date date
insert into Replaced_parts values('AAAAA/1', 'BBBBB/1', '2012-Feb-16');
insert into Replaced_parts values('BBBBB/1', 'FFFFF/1', '2012-Feb-23');
insert into Replaced_parts values('YYYYY/3', 'ZZZZZ/3', '2012-Mar-17');
insert into Replaced_parts values('FFFFF/1', 'LLLLL/1', '2012-Mar-18');
insert into Replaced_parts values('LLLLL/1', 'HHHHH/1', '2012-Mar-19');The question is how do I issue a select using 'AAAAA/1' and get the result 'HHHHH/1'
i.e. (A... -> B, B->F, F->L, L->H)
and select using 'YYYYY/3' to get 'ZZZZZ/3' (Y... ->Z)?
It would be really nice if I could also get my original value, say, 'CCCCC/1' if there is no entry
for 'CCCCC/1' in the replaced_parts table (maybe NVL?).
I have googled and tried various combinations of CONNECT BY, PRIOR, ISLEAF... &c. but
am beating my head off a brick wall at the moment.
TIA,
Paul...

Hi, Paul,Hi again Frank - couldn't sleep and am back at the "£$%^&* computer...
Yeah - it's a pity they weren't correct - I'll make doubly sure in future - see
my edited post (with DROP TABLE commands inter alia - I also removed
Order_Parts.User_Number since it was redundant - all that's needed is
Order_Number (normalisation) so now your SQL doesn't work - sorry
about that.
Just saying something "doesn't work" isn;t very helpful. What exactly is wrong with the SQL
statements I posted? Point out a couple of places where they are wrong, and explain how
you get the right results in those places.Nothing is wrong with your SQL - I meant *sorry* about the confusion in the DDL/DML from my end.
Now, I'm sorry again about the ambiguity of my English.
I'll reconstruct the original data that I gave you and re-run your SQL against that data - again,
this is *totally* my fault.
My tables creation script seems to work fine now - I've edited my reponse to Solomon - the definitive scripts
are now there - with Order_Parts.User_Number gone and the TO_DATE(...) as
you suggested - the VARCHARs seemed to give the right result though - but I
agree that if there's a correct way of doing it, then it should be done that way.
Remember why you need to go to the trouble of posting CREATE TABLE and INSERT statements
for some sample data here. It's to allow the people who want to help you to re-create the prolem
and test their ideas. I know, and that's why I did it - the OR REPLACE that I added (stupidly and without thinking or testing) was
so that people wouldn't have to go to the trouble of dropping the tables - I have now added
DROP TABLE blah... to the beginning of the script so it won't be necessary.
I have over 600 posts on this forum and only 26 questions - most of my time
spent here is trying to help (to the best of my limited ability - I'm not a guru
like yourself) and learning - it's amazing the number of times problems that
I've seen here have subsequently arisen at work - and I am frequently
frustrated by some posters' inability to explain their problem or at least give test
cases.
I can forgive bad English (except my own) - not everybody is a fluent speaker of the language,
but SQL should run no matter what language one speaks.
I appreciate that people are volunteering their time and effort here and I really do
try and make it as easy as possible for them when I ask questions - I messed up
this time, I'm afraid. It might also be the fact that I'm moving between SQL*Plus
and SQL Developer and a text editor that I got confused (plus, fatigue didn't help...)
In general, other people are not going to test anything on your system. I'm going to test
things on my system, Solomon will test things on his system, and other people will test things
on other systems. Well, if ever you're in Dublin ;). Again, I appreciate the effort that you, Solomon and sKr have
gone to in helping me.
Your INSERT earlier statements did not work on my system, because you were using a VARCHAR2
in a place where a DATE was required. The correct thing to do is to use DATEs where DATEs are required. Indeed, and I agreed with you that if there's a right way of doing it, then it should be done that way.
If your NLS settings are such that this is not causing you any errors right now, it's still a good
idea for you to fix it; but, at any rate, whether it works on your system isn't what's important in
this case; you're posting it to run on other peoples' systems.Ahhh.... <the blinding light of a moment of epiphany descends on Paul> I didn't realise it was
an NLS setting - of course Americans will be different - it's just that I thought that YYYY-Mon-DD
worked everywhere (I tried to avoid the day-first/month-first pitfall ) but now that you've explained
it to me, I'll *never* make that mistake again.
Yes - my mistake - I've now corrected the error
Where are the desired results? Don't merely hide them in an old message; post them in a new message.OK. I'll put it in a reply to this post. I really am endeavouring to be as clear as possible - please
excuse my errors - I will do better in future. I'm also very annoyed at my own incompetence and at
having put you to more trouble than you would have had to go to if I had my wits about me.
- should I keep Order_Parts.User_Number even
if it isn't conformant to normalisation rules?
If you have a good reason, it's okay to store de-normalized data. For example, some address tables in
the US contain both state and ZIP code, even though state is fucntionally depenedent on ZIP code. I think that in this case, denormalisation is not called for.
Re. the ZIP code thing, yeah, sure AIUI, the first two digits are dependent on the state, but the
last three? They're more or less random - at least in the sense that there's no way to type
in an address and calculate (mathematically, using a formula) them - so unless one were
to have weird SQL lookups to a "State" table for the first two digits and then take the final
three from a user-entered string field, then do a TO_CHAR on the returned 2-digit state number and add
this to the 3-character one - I can't see how the ZIP code is an example of this? But, maybe
(unless you wish to discuss that) we're getting side-tracked. Perhaps I'll ask this question
on comp.databases.theory?
Oracle actually added a new feature in version 11 (virtual columns) to make de-normalizing easier.Hmmm... is adding virtual columns denormalisation per se? My favourite "cheap'n'cheerful"
db server (Firebird) has had a COMPUTED BY clause (same idea) for yonks (> 12yrs) - no data
is actually stored - rather it is calculated on the fly. Another one for comp.databases.theory
perhaps?
BTW, wouldn't triggers remove all this hassle? It was my first idea, but trying to do it
purely through SQL is now *obsessing* me ;)
That would be another example of de-normalization. If the benefits of doing that outweigh the
costs, then go ahead. A trigger will take some effort to maintain, and it will make all DML slower, regardless
of how often that derived value is needed. Having the extra column will make some queries simpler and faster. Disk is cheap. Have an Original_Orders table (never changes) and a Revised_Orders table. When
a part replacement occurs - for orders that haven't been fulfilled (boolean flag?), change the
old part number to the new one. I can't imagine that replacement occurs very frequently, so
the expense of a trigger would IMHO be minimal - plus the down side of any trigger would
be mitigated by greatly simplifying the production of the Revised_Orders report?
... I'll experiment with what you've given me so far - but it's 23:40 here now, so I won't
get a chance to do it tonight - unfortunately, I *do* have to sleep.
If you haven't tested it yet, why did you start this message saying "your SQL doesn't work"?Sorry - what I meant was it obviously doesn't work when this eejit (i.e. me) has changed
the table structure - I did run it quickly (your 1st statement) against the (revised table
structure, the one you hadn't seen and I don't think even a man of your great SQL talents
can be expected to write working queries against unknown table structures :)).
Again, thanks for your help so far - I'll post the *_correct_* DDL and DML as a reply to this post
with the desired result. I'll also reconstitute the old (i.e. the one you worked against) tables
and data and let you know - again as a reply to this post - if I can at least learn something
from my fiasco, it won't have been a total waste of my time, and again, apologies for
wasting yours.
Thanks again and rgs.

Using assign-activity:Append to append child nodes in XML-tree within loop

I would like to produce an XML looking something like this (just an example):
<Customer>
<Name>Tom</Name>
<Invoices>
<Invoice>
<InvoiceData>.....</InvoiceData>
</Invoice>
<Invoice>
<InvoiceData>.....</InvoiceData>
</Invoice>
</Invoices>
</Customer>
For different reasons (composite PK's in DB etc) I have to first get the Customer-data, and then get each Invoice for that customer.
Then I have to loop the Invoices and append each Invoice-node to the XML, ending up with the whole thing when the loop is finished.
This should be pretty simple (I guess), and I have tried different variations of the Append (assign activity), but everytime I end up with only the last Invoice-node.
I can see in the Flow-window of the BPEL Console that it is not the same Invoice-node I'm appending within the loop-iterations, so that can not be the case in any way.
In other words it seems to copy instead of appending.
What is wrong ?
Is this a bug in the Append function ?
Any suggestions to other approaches that might work ? (I have to use the loop to get 1 and 1 Invoice-node though, and in that way put the whole XML together in some way)
Edited by: user1694182 on 09.okt.2008 05:08

Thank you for your answer.
After taking your "debugging"-suggestions at hand and running some tests, I can now see that it gets appended in some way, but not correctly.
1st LOOP ROUND:
<installation>
<measurePoints>
<measurePoint><measurePointId>308</measurePointId>...</measurePoint>
</mesurePoints>
</installation>
Correct so far.
2nd LOOP ROUND:
<installation>
<measurePoints>
<measurePoint><measurePointId>322</measurePointId>...</measurePoint>
<measurePoint><measurePointId>322</measurePointId>...</measurePoint>
</mesurePoints>
</installation>
So now it appends the new measurepoint, but overwrites the 1st as well... Strange..
3rd LOOP ROUND (last round):
<installation>
<measurePoints>
<measurePoint><measurePointId>382</measurePointId>...</measurePoint>
<measurePoint><measurePointId>382</measurePointId>...</measurePoint>
</mesurePoints>
</installation>
So suddenly the same Append doesn't append, but overwrites the 2 I had with the new measurepoint...Strange...
WHAT I DO IN MORE DETAIL:
1: Assign(copy) the whole XML in the 1st loop round. (Copy - FROM: submitInstallation_InputVariable - TO: Powel_InstallationServiceInput)
2: Within each loop round I collect the whole XML with just 1 measurePoint (TransformActivity - FROM: DBAdapter-output - TO: submitInstallation_InputVariable).
3: Within each loop round I then append the new measurePoint (collected in step 2) to the measurePoints-node. (Append - FROM: submitInstallation_InputVariable - TO: Powel_InstallationServiceInput)
PS! I can see in the BPEL Console that it is a new measurePoint that gets collected in step 2, and just 1 node.
Help/tips on this is very appreciated ! :-)

How to avoid showing extra accessor nodes in "af:tree" component?

I work with with JDev 11.1.2.3. (ADF BC, ADF Faces stack)
I have a data structure that is hierarchical (table references itself), and another table that referneces first one.
First table contains names of containers (container can be in another container), and second table holds contents of containers.
I want to create tree that shows data from both tables.
When I create tree binding I have two accessors for first table, one with which table references itself and another accessor with which second table references the first one.
Because of that in rendered tree under each node which represents first table's row I get two extra nodes (one for each accessor).
Is it possible not to show those extra nodes but that everything is packed under the same hierarchy?
Best regards,
Nebojsa

The logic here is pretty similar to the one with folders and files. Folders are container types and files are just leaf nodes (can't contain other files).
I don't want under each folder node to have two new container nodes - one that hold other subfolders, and another one that hold just files. And that's just what I get now.
How to avoid that?
Anybody?

How to open a dialog box while double cliking the JTree child node.

hi
I am new to Swing technology.I want to open a dialog box while double clicking the child node of a tree.Could anyone please send me some examples.

mouse listener on the tree, see if the click count is 2 and what node it clicked, open the dialog. MouseEvent can give you the click count and x/y coordinate, JTree can tell you what node is at that coordinate.

Selected node in a tree table (via Data Controls and not managed bean)

I am facing some problems in getting the selected row in a tree table.I have used data controls for creating the tree on the page.
I have 3 POJO's,ex; Class AB which has a list of Class CD.And Class CD has a list of class EF. (Used for the tree table)
Now i have a java class, called MyDelegate.java which has a list of AB.I generated data controls off this MyDelegate class and have dropped the ABlist as a tree table (also displaying CD and EF in the tree table).
It displays fine with nodes of AB,CD (child of AB)and EF(child of CD)
The tree table is not bound to any managed bean.
For performing actions on the tree, i create a method - "doSomething() in the delegate class",generate data controls and drop it as a button.
Inside doSomething(), i need acess to the selected node in the tree (it can be a node of type AB or CD or EF).
The problem: I always get access to the node of type AB, and not the child nodes no matter what i click in the tree table.
doSomething(){
DCBindingContainer dcBindingContainer = (DCBindingContainer)ADFUtil.evaluateEL("#{bindings}");
DCIteratorBinding dcTreeIteratorBinding = dcBindingContainer.findIteratorBinding("lstABIterator");
RowSetIterator rowTreeSetIterator = dcTreeIteratorBinding.getRowSetIterator();
DCDataRow rowTree = (DCDataRow)rowTreeSetIterator.getCurrentRow();
if (rowTree.getDataProvider() instanceof AB) {
          //do something
          AB selectedAB = (AB)row.getDataProvider();
} else if (rowTree.getDataProvider() instanceof CD){
          //do something
} else if (rowTree.getDataProvider() instanceof EF) {
          // do something
How do i access the "selected child node of the tree table" here in the delegate class method? Pls help.

Hi Frank,
Thanks for the response. In my case, i dont have a managed bean, so i am slightly unsure how to do it.
There is a mention "Note that another way to access the treeTable component at runtime is to search for it in JavaServer Faces UIViewRoot. This latter option allows you to write more generic code and does not require to create a page dependency to a managed bean"
How do i use this adf view root (without a managed bean) to get hold of the selected row in the tree table. Pls help.
Thanks.

Tree component. ::: Movable nodes.

Hi guys,
Can i able to move or change the node structure( folder structure ) by
drag and dropping a node with in tree component (af:tree) ?
or
is there any other components supporting this kind of functionality ?

Hi,
don't think this is working in the JDeveloper 11 ADF Faces RC preview. I'll keep this as a usecase on my list of things to follow up with. Note that - if this worked .- a drag and drop on a tree wont change the underlying business model without you adding any code to perform the change.
