FRM-47323: no nodes are selected in the tree.

Hi all

I'm currently upgrading my forms 6i in 11g. 6i form is currently using the element of the hierarchy tree.
After the form conversion, 11 g and the execution of the form I get the error FRM-47323 following "no nodes are selected in the tree.
The same shape work very well in the environment of 6i.

This error is not documented anywhere and am not sure why only after upgrading to 11g it gives this error.

After debugging the code, I noticed that the following code will fail with this error:

Declare
.....
current_node FTREE. NŒUD;
htree;
.....
Begin
...... At this point, it fails with the error FRM-47323.
current_node: = Ftree.Get_Tree_Selection (htree, Ftree.Get_Tree_Property (htree, Ftree.SELECTION_COUNT));
.....
End;


Any help will be appreciated. Let me know if you need more information on this issue.

current_node: = Ftree.Get_Tree_Selection (htree, Ftree.Get_Tree_Property (htree, Ftree.SELECTION_COUNT));

The problem is the reference "Ftree.SELECTION_COUNT". The Get_Tree_Selection function returns the reference of the selection tree node NŒUD. The SELECTION_COUNT variable stores a number that represents the number of nodes that are selected. Its been more than a table that a NUMBER because it contains the reference of the index for each node selected in the tree. ;-)

If you need to know which node is the current selected node, try to use: SYSTEM. Trigger_Node instead.

Hope this helps,
Craig B-)

  • How the records are selected in the database

    Hello

    How the records are selected in the database


    Thank you.

    Read articles on JDBC, here is what I understand...

    If I set LignesMax = 1 (in out select adapter DB) and I have 30 record in the table that satisfy the select query then what line is picked up? the first in the table or randomly any folder?

    The query returns the first line of the result set.  Not just a random line.  However, to get the rows to return in the result set in a specific order, you must include an order by clause, or the query will return rows in random order.

    And if I set LignesMax = 0 (unbounded, means any number registration) in this case if my select query satisfy 100 million documents so all million records will be picked up once, in one cycle?

    The answer to this depends on the size of the extraction of the query.  If the size of the extraction is > = 100 million, everything goes back in a single cycle of the DB.  If< 100="" million,="" then="" it="" will="" be="" divided="" into="" multiple="" trips="" to="" the="">

  • Form inputText select in the tree in the pop-up dialog box

    I have two entity objects. Recursive tree structure, the other has a foreign key to the first.

    The form of the second entity ADF, I need to make the user choose attribute for foreign key in a tree, so I've created a popup, a dialogue and a tree in it. Then we add a showPopupBehavior foreign key of the second entity object attribute inputText.

    Using a bean to backup, when you click on the button "OK" in the dialog box, I manage defining the foreign key of the selection attribute. I have the following code:

  • Select only the objects in a rectangle selection

    I am a new user of Illustrator CS5, switching from Freehand. I'm trying to find out if there is a way to select only the objects in a marquee? In AutoCAD, you can make a selection on the left window to the right and only those objects entirely in the window are selected. If you the window right on the left all the objects that are "crossed" or affected by the window are selected. Is there a similar technique in Illustrator?

    Currently, I have to select the objects, and then go back and hold the SHIFT key to deselect the object I don't want, or place objects on different layers and then lock the layers to prevent additional items get selected.

    In AutoCAD, my main program, you simply draw a window selection, left or right, depending on what your next step would be. No special tools or rocking or thinking, that's just the selection primary process and very intuitive.

    I posted a discussion on the Illustrator forum several months ago, which still arouses comments so this seems to be a tool that would be appreciated by many users. Someone posted a script but it has not worked for me yet.

    Thank you for everything that you can do to solve this problem.

    This is a copy of my last post of the original thread. I found some discussions confused because I have no experience in writing or by using scripts. So I copied all the recommendations in a document to read without the comments and digressions. After several hours and a lot of searching on Google I found what solution adapted to my goal, which was a selection process fast and simple with fewer steps to use.

    So, I think I have this job. The following is what I did:

    1 copy the script by Carlos Canto post #11 here:

    http://forums.Adobe.com/thread/856221?start=0&TSTART=0

    2. open the ExtendScript Toolkit Utilities > Adobe utilities - CS5.5 > ExtendScript Toolkit CS5.5 > ExtendScript Toolkit CS5.5.App

    3. when the program opens, paste the script in the large Panel on the left.

    4. then go to file > save as.

    5. that the dialog box click on the arrow next to the save box slot to expand the section options.

    6. next, go to Applications > Adobe Illustrator CS5.1 > Presets > en_US > Scripts.

    7. then, in the Save as box enter a name to identify the script (I named mine Window1).

    8. click on save and close the Toolbox.

    Launch Illustrator and open a drawing.

    1 using the rectangle tool, I drew a rectangle around the objects.

    2. make sure that the new rectangle is selected.

    3. I went to file > Scripts > Window1.

    4A got an error message - error 8705: target layer cannot be changed 25-> iart.selected + true line:

    Oops, you must have ALL unlocked layers.

    5. you click OK.

    6 unlocked all the layers.

    7. my new activated rectangle.

    8. went to file > Scripts > Window1.

    9 here! Items in the rectangle are selected and the rectangle is removed.

    So yes, this script works as requested. Thank you, Carlos.

  • Table tree - Select All child nodes at the same time when the Parent node is selected.

    Hi all

    I am relatively new to ADF and JDeveloper, and so I hit a problem I can't deny.

    I have a tree table that looks like the following...

    1 status | Name | Employee ID

    -> Status 2. Name | Employee ID | etc. | etc.

    -> 3 status. Name | Employee ID | etc. | etc. | etc.

    I want to do is when I select the node from top of the line/parent (line 1) page I would like child nodes (lines 2 and 3) to choose from in the same mouse clicks.

    In the end I will be citing a listener of the property on a button, once the selection was made, to change the value of the 'Status' column in all three levels that have been selected.

    NB. each level in the tree above is derived from 3 views distinct, who are joined on the employee ID.

    Thanks in advance for your help and your advice.

    Kind regards

  • How to write a hierarchical query so that only the child nodes are displayed?

    Hi all

    I have a hierarchical query that I use in an area of tree demand APEX and there are nodes that have no children and I am trying to find a way to not display these nodes. Essentially if the user does not have to develop a lot of knots to know that nothing exists at the most detailed level.

    The data are based on the Oracle Fusion FND tables but for example purposes here is enough data to illustrate my question:


    create table APPL_TAXONOMY_HIERARCHY (SOURCE_MODULE_ID varchar2(30), TARGET_MODULE_ID varchar2(30));
    create table APPL_TAXONOMY_TL (module_id varchar2(30), description varchar2(100), user_module_name varchar2(30), language varchar2(5));
    create table APPL_TAXONOMY (MODULE_ID    varchar2(30),    MODULE_NAME    varchar2(30), MODULE_TYPE varchar2(10),    MODULE_KEY varchar2(30));
    create table TABLES (table_name varchar2(30), module_key varchar2(30));
    
    

    insert into APPL_TAXONOMY_TL values ('1', null, 'Oracle Fusion', 'US' );
    insert into APPL_TAXONOMY_TL values ('2', null, 'Financials', 'US' );
    insert into APPL_TAXONOMY_TL values ('3', null, 'Human Resources', 'US' );
    insert into APPL_TAXONOMY_TL values ('20', null, 'Accounts Payable', 'US' );
    insert into APPL_TAXONOMY_TL values ('10', null, 'General Ledger', 'US' );
    
    insert into APPL_TAXONOMY_HIERARCHY values ('1', 'DDDDDDDD');
    insert into APPL_TAXONOMY_HIERARCHY values ('2', '1');
    insert into APPL_TAXONOMY_HIERARCHY values ('3', '1');
    insert into APPL_TAXONOMY_HIERARCHY values ('4', '1');
    insert into APPL_TAXONOMY_HIERARCHY values ('10', '2');
    insert into APPL_TAXONOMY_HIERARCHY values ('20', '2');
    
    insert into APPL_TAXONOMY values ('1', 'Fusion', 'PROD', 'Fusion');
    insert into APPL_TAXONOMY values ('2', 'Financials', 'FAMILY', 'FIN');
    insert into APPL_TAXONOMY values ('10', 'GL', 'APP', 'GL');
    insert into APPL_TAXONOMY values ('3', 'Human Resources', 'FAMILY', 'HR');
    insert into APPL_TAXONOMY values ('20', 'AP', 'APP', 'AP');
    
    insert into tables values ('GL_JE_SOURCES_TL','GL');
    insert into tables values ('GL_JE_CATEGORIES','GL');
    

    My hierarchical query is as follows:

    with MODULES as
    (
    SELECT h.source_module_id, b.user_module_name, h.target_module_id
          FROM APPL_TAXONOMY_HIERARCHY H,
          APPL_TAXONOMY_TL B,
    APPL_TAXONOMY VL
    where H.source_module_id = b.module_id
    and b.module_id = vl.module_id
    and vl.module_type not in ('PAGE', 'LBA')
    UNION ALL
    select distinct table_name, table_name,  regexp_substr(table_name,'[^_]+',1,1) 
    from TABLES --needed as a link between TABLES and APPL_TAXONOMY
    union all
    select module_key as source_module_id, module_name as user_module_name, module_id as target_module_id  from appl_taxonomy VL where VL.module_type = 'APP')
    SELECT  case when connect_by_isleaf = 1 then 0
                when level = 1             then 1
                else                           -1
           end as status,
    LEVEL,
    user_module_name as title,
    null as icon,
    ltrim(user_module_name, ' ') as value,
    null as tooltip,
    null as link
          FROM MODULES
          START WITH source_module_id = '1'
          CONNECT BY PRIOR source_module_id = target_module_id
    ORDER SIBLINGS BY user_module_name;
    

    In Oracle APEX, this gives a tree with the appropriate data, you can see here:

    https://Apex.Oracle.com/pls/Apex/f?p=32581:29 (username: guest, pw: app_1000);

    The SQL of the query results are:

    STATUSTITLE LEVELVALUE

    ---------- ---------- ------------------------------ ------------------------------

    11 oracle FusionOracle Fusion
    -12 financial tablesFinancials
    -13 accounts payableAccounts payable

    -14 GLGL
    05 GL_JE_CATEGORIESGL_JE_CATEGORIES
    05 GL_JE_SOURCES_TLGL_JE_SOURCES_TL
    02 human resourcesHuman resources

    The lowest level is the name of the table to level 5. HR is not any level under level 2, in the same way, "AP" (level 4) has nothing below, i.e. no level 5 and that's why I don't want to show these nodes. Is this possible with the above query?

    Thanks in advance for your suggestions!

    Hello

    The following query will include only the nodes of level = 5 and their ancestors (or descendants):

    WITH modules LIKE

    (

    SELECT h.source_module_id

    b.user_module_name AS the title

    h.target_module_id

    To appl_taxonomy_hierarchy:

    appl_taxonomy_tl b

    appl_taxonomy vl

    WHERE h.source_module_id = b.module_id

    AND b.module_id = vl.module_id

    AND vl.module_type NOT IN ('PAGE', "LBA")

    UNION ALL

    SELECT DISTINCT

    table-name

    table_name

    , REGEXP_SUBSTR (table_name, ' [^ _] +')

    From the tables - required as a link between the TABLES and APPL_TAXONOMY

    UNION ALL

    SELECT module_key AS source_module_id

    AS user_module_name module_name

    module_id AS target_module_id

    Of appl_taxonomy vl

    WHERE vl.module_type = 'APP '.

    )

    connect_by_results AS

    (

    SELECT THE CHECK BOX

    WHEN CONNECT_BY_ISLEAF = 1 THEN 0

    WHEN LEVEL = 1 THEN 1

    OF ANOTHER-1

    The END as status

    LEVEL AS lvl

    title

    -, NULL AS icon

    , LTRIM (title, "") AS the value

    -, NULL as ToolTip

    -, Link AS NULL

    source_module_id

    SYS_CONNECT_BY_PATH (source_module_id - or something unique

    , ' ~' - or anything else that may occur in the unique key

    ) || ' ~' AS the path

    ROWNUM AS sort_key

    Modules

    START WITH source_module_id = '1'

    CONNECT BY PRIOR Source_module_id = target_module_id

    Brothers and SŒURS of ORDER BY title

    )

    SELECT the status, lvl, title, value

    -, icon, tooltip, link

    OF connect_by_results m

    WHEN THERE IS)

    SELECT 1

    OF connect_by_results

    WHERE the lvl = 5

    AND the path AS ' % ~' | m.source_module_id

    || '~%'

    )

    ORDER BY sort_key

    ;

    You may notice that subqueries modules and the connect_by_results are essentially what you've posted originally.  What was the main request is now called connect_by_results, and it has a couple of additional columns that are necessary in the new main request or the EXISTS subquery.

    However, I am suspicious of the 'magic number' 5.  Could you have a situation where the sheets you are interested in can be a different levels (for example, some level = 5 and then some, into another branch of the tree, at the LEVEL = 6, or 7 or 4)?  If so, post an example.  You have need of a Query of Yo-Yo, where you do a bottom-up CONNECT BY query to get the universe of interest, and then make a descendant CONNECT BY query on this set of results.
