• Of the data in the table to get a tree using declarative and perform operations above.

  Hello

  I use Jdeveloper 11.1.2.4.

  I'm creating a declarative component. The component is supposed to display the data in a table and allow the user to remove entries of it.

  The table should be included in a pop-.

  From now on, I made a picture of the tree within a collection of panels. I'm creating a tree in the pagedefinition of the ViewController project file and passing the tree of the same model to the component attribute declarative. After binds the attribute passed to table component tree declarative, I am able to fill lines. First please let me know if my approach is correct or not. The user can select any row of the table and press delete. The button must remove the entry from the table. Is it possible to remove operation on the table in the declarative component.

  Thank you

  First of all, please let me know if my approach is correct or not.

  Seems ok

  The user can select any row of the table and press delete. The button must remove the entry from the table. Is it possible to remove operation on the table in the declarative component.

  You have several ways to do this:

  (a) similar to the declarative component attribute, you can bind methods, for example: ADF Essentials eCourse - declarative components ADF: work with methods

  (b) pass the name of the iterator to your component and then use it to remove programmatic in backing bean

  (c) create pageDef declarative component for, something similar to this: ADF practice: liaison for component container declarative

• How to develop the Table of Backing Bean tree nodes?

  I have a requirement where I want my table to be expanded all three nodes. InitiallyExpanded = True develops alone.
  Is it possible to have all the Backing Bean nodes?
  
  Code snippet will be very useful.
  
  Thanks in advance,
  TK

  For all nodes in a treetable can be expanded, you will need to add all the rows of the disclosedRowKeySet.

  (1) create a binding for the treetable in average managed code as "treeTable.
  (2) create a CommandButton named "Expand" (under the picture of the tree) and Visible set to false and create a link to a page named expandButton & in the get accessor for the commandButton control method, call the following method:

  public RichCommandButton getExpandButton() {}
  this.expandTreeTable ();
  }

  private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();

  private void expandTreeTable() {}
  If (this.treeTable! = null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  Model CollectionModel = (CollectionModel) treeTable.getValue ();
  JUCtrlHierBinding = treeBinding
  (JUCtrlHierBinding) model.getWrappedData ();
  JUCtrlHierNodeBinding RootNode = treeBinding.getRootNodeBinding ();
  disclosedTreeRowKeySet = treeTable.getDisclosedRowKeys ();
  If (disclosedTreeRowKeySet == null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  }
  List = firstLevelChildren
  rootNode.getChildren ();
  for (node JUCtrlHierNodeBinding: firstLevelChildren) {}
  List ArrayList = new ArrayList();
  List.Add (node.getRowKey ());
  disclosedTreeRowKeySet.add (list);
  expandTreeChildrenNode (node, treeTable, list);
  }
  treeTable.setDisclosedRowKeys (disclosedTreeRowKeySet);
  }
  }

  Private Sub expandTreeChildrenNode (RichTreeTable, rt,
  JUCtrlHierNodeBinding node,
  The list parentRowKey) {}
  ArrayList children = node.getChildren ();
  List rowKey;
  If (children! = null) {}
  for (int i = 0; i)< children.size();="" i++)="">
  rowKey = new ArrayList ();
  rowKey.addAll (parentRowKey);
  rowKey.add (((JUCtrlHierNodeBinding) children.get (i)) .getRowKey ());
  disclosedTreeRowKeySet.add (rowKey);
  If (((JUCtrlHierNodeBinding) (children.get (i))) .getChildren () is
  null)
  continue;
  expandTreeChildrenNode (rt,
  (JUCtrlHierNodeBinding) (node.getChildren () .get (i)),

• Table of campus Solution 9.0 academic organization and his tree

  People,

  Hello. I implement 9.0 Solution Campus of a college.

  I am confused on how to type in data between the academic organization Table and his tree to tree Manager. 2 Navigations are below:

  Implemented AWAR > Foundation Table > academic Structure > academic > academic organization Table

  Tree Manager > create a new tree > tree: my academic organization

  According to the document - Campus Solution 9.0 Basic Application to Page 152 - academic organization of understanding:

  "Before you start using academic institutions, you must first use PeopleSoft tree handler to set academic organizations themselves, the hierarchy and the levels of each of the academic institutions and the relationships between academic institutions in the hierarchy."

  The document at Page 153: "system displays information entered through organizing academic Manager tree to tree in PeopleSoft." You can edit this information. »

  The document to Page 154: '' you should add new academic organization through PeopleSoft tree Manager. ''

  The meaning above, it seems that we create the tree first and then type in the data in the Table academic organization after him. But the 2 Navigations above don't work that way. The Navigations 2 above work the way below:

  Tree Manager > create a new tree > tree: my academic organization

  Step 1: Add level - a level tree name lookup table arrives.

  Step 2: Root node - table of correspondence of school organization coming up.

  Set Up AWAR > Foundation Table > academic Structure > academic organization Table: this table has no place to link to the tree of academic organizations.

  Navigation, we must enter data in the Table of level names tree and Table organization academic at first and then when to create the tree, 2 tables come tables selected data. After this, I run Set Up AWAR > Security > Secure Student Administration > process > update security - Acad Org. But this process gets the error and does not swell report SQR.

  My question is:

  Because document instruction does not work with sailing, all folk can me the concrete way to enter data in the Table, academic organization and his tree to tree Manager?  What is the first? What's the second? Where is Navigation?

  Thanks in advance.

  People,

  Hello. The problem is solved by myself.

  Hi Timo,

  Thanks for your quick response.

  I can't use listeners phase because I use jsff jspx.

  in any case, I found the solution by using the approach below
  creating a default method on the flow of task 1) and storage and by setting this method as the default activity in the workflow
  class Test
  {
  private RowKeySetImpl ps;

  public void initTreeTableNode() / * this method is used to develop all of the tree nodel.
  {
  if(PS==null)
  PS = new RowKeySetImpl (true);
  PS = new RowKeySetImpl (true);
  }
  }

  and store a page flow scope and usage disclosedRowKeys = "#{pageFlowScope.expanedAllNodes}" in treetable jsff on page "

  Thank you best regards &,.

• Get the values of default table row when the page loads

  Hello

  I am running JDev 11.1.1.7. We have a page that contains two tables in a relationship of the master / detail of nickname. We can do a real master ADF / detail with view items related because the query for the 2nd table is complex and works best when queries with binding settings. The View object for the 2nd table has a request with 2 link params as it can get in the first table. Thus, when a line is selected in the first table we want to execute ExecuteWithParams on the object from view of the table 2. We do it in the Bean managed for the page in a method that is the selection to the first table listener. It works fine except when the page initially loads, the first line is selected by default. When the default value is selected the selection listener is not triggered.

  I've seen the suggestion of not having a line selected by default when the page loads by removing the value selectedRowKeys on the table. However, we do not want that the 1st row of the table secondary master to be selected by default and we as the table of detail to show the correct corresponding lines.

  Steve

  Steve,

  Not really sure when you say that the 2nd table is complex and may not use the master detail. If the settings link in the parent table, you can set the ViewLink accordingly and it should work, right?

  In any case, if you're after the execution of methods on the loading of the page, you will find the links below.

  If it's a working group, you can add a methodCall as activity by default and UTF, you can use phase listener (if listener server does not).

• Forms - calculation of percentages are based on the percentages of parent in a tree structure

  Hello

  We have a scenario where we build a tree using a standard package available in oracle forms when new block and fill a tree structure of multi Instance.

  The block is based on a single table.

  The tree is is filled. The problem is with the percentage calculations. As the percentage of the child dependent parent

  PERCENTAGE of PARENT- CHILD LEVEL

  1                101                       0                                 45

  1                102                      0                                  35

  1                103                      0                                   30

  2 201 101 PERCENTAGE OF PARENTS 101

  2 202 101 PERCENTAGE OF PARENTS 101

  2 203 102 PERCENTAGE OF PARENTS 102

  2 204 102 PERCENTAGE OF PARENTS 102

  3 301 201 PERCENTAGE OF PARENTS 201

  You can get the percentages to level 2, level 3.

  I was wondering how this can be done in oracle forms... for example... .to child 201, is the percentage of the 101 level... but level 101 is also filled in the buffer of the block as well as all Level1s...

  All entries are appreciated.

  Thanks and greetings

  The solution me. Idea is to use the 'Post' at the time be called in a loop. Then POST will write in the validation of the database but strict.

  The idea is that at the time of execution, we would be able to select "Not ENGAGED" current session data in the database and use it more for treatment.

• Rules of naming on several tables

  Is there a quick way to the application of several tables-naming rules both in a relational model? The only way to do it, I found is to click with the right button on a table on the diagram canvas, choose Properties and click on the button 'Naming Rules. It is fine for a single table, but it's a bit tedious if there are many. If I select more than one table and apply the rules naming this method that the rules only get applied to the last table selected, not all the tables. While I can choose several tables in the browser tree there is no context menu right-click Allow me to do anything.
  
  I looked in the help of the naming rules and get 9 hits, none help. Nothing at Universal help either (aka Google).
  
  Probably I'm missing something really obvious...

  You can apply naming rules in the relational model all - it is in the context menu for the node of relational model in the browser - "apply naming key standards and constraints."

• How the comprehensibility of the tables gets reduced?

  How comprehensibility of the tables gets reduced if Gets the size of the table and relational tree depth increases. How can I show that the size of the table and the depth of relatonal tree increase reduced the comprehensibility.

  user1151621 wrote:

  You started with a very vague and confusing issue. When asked for clarification, you didn't change the word 'table' to the 'schema '. The question is still vague and confused. When asked further clarification, you didn't repeat the same question.

  Go back to the drawing board and rephrase the question.

  We do not know what you mean by "understanding of the schema.
  We do not know what you mean by 'reduction' of "understanding of the schema.
  We do not know what you mean by "relational tree depth."
  We do not know how the size of the table or the "relational tree depth" refers to "understanding of the schema.

  ... I was wondering if the name that (...), select help here...

  Subqueries certainly help. They do not have to be in a WITH clause. views online would work in this case.

  I have to respect the tree structure, because the table contains several separate trees...

  In a tree, each node has only one parent (if any). In my_tree_links, id = 26 has two parents (10 and 20), so this isn't a tree. You not helping yourself or someone else if you say it is.

  INSERT INTO my_objects
  SELECT LEVEL
  , mod (LEVEL,7)
  FROM DUAL
  CONNECT BY LEVEL < 27;
  /
  

  When end you a statement with a semicolon followed immediately by a slash, then the statement is executed twice. I suppose that this isn't what you wanted. If my_objects.id is not unique, the solution below will have some minor changes.

  To limit the results to the nodes that have an ancestor with the target node, you can do a Query of Yo-Yo , where you do a query of bottom-up first, to find all the ancestors without parents of the target node, then do a query from top to bottom, to find all their descendants, like this:

  VARIABLE     target_id     NUMBER
  EXEC  :target_id := 26;
  
  WITH     got_roots     AS
  (
       SELECT     id_up
       FROM     my_tree_links
       WHERE     CONNECT_BY_ISLEAF     = 1
       START WITH     id_down     = :target_id
       CONNECT BY     id_down     = PRIOR id_up
  )
  ,     got_descendants     AS
  (
       SELECT     id_down
       FROM     my_tree_links
       START WITH     id_up     IN (
                           SELECT     id_up
                           FROM     got_roots
                         )
       CONNECT BY     id_up     = PRIOR id_down
  )
  SELECT DISTINCT
       mo.*
  FROM     my_objects     mo
  JOIN     got_descendants     gd  ON     mo.id     = gd.id_down
  WHERE     mo.value     = (
                      SELECT     value
                      FROM     my_objects
                      WHERE     id     = :target_id
                   )
  AND     mo.id          != :target_id     -- If wanted
  ;
  

  Output (where: target_id = 26):

  `       ID      VALUE
  ---------- ----------
          12          5
          19          5
           5          5
  

  Always tell what version of Oracle you are using. The query above works in Oracle 10 (and), but could be adapted to run on Oracle 9.

  Whevever you need to do a CONNECT BY query as a join, it is faster if you can CONNECT BY first, in a separate subquery and join the results for the other tables. This is what the second auxiliary request, got_descendants, is for.

  What results would you if: target_id = 8?
  The query above, as written, would not include id = 1. If you want, you will need to somehow enter the root ID for example 1, which are never id_down, in the same column with all the id_downs. You can do it with a UNION in the query, but you can change permanently my_tree_links so that these roots have some parent (themselves or some dummy, like NULL).

• Tree nodes are duplicated

  Hello
  I want to create a relationship of the master / detail between a tree (master) and a table (detail) reading. Tree consists of three levels, Status (parent), FormType (child), FormNumber (grandchild). The SQL in the t for each query is as follows,
  Parent - status-> SELECT DISTINCT CREATED_BY, STATE of LCS_NAVIGATION_TREE_V WHERE CREATED_BY =: pCREATED_BY
  Child - FornType--> SELECT DISTINCT FORM_NAME, $form_id, CREATED_BY, LCS_NAVIGATION_TREE_V STATUS
  A grandchild - FormNumber-> SELECT $form_id, FORM_NAME, TRACKING_NUMBER, CREATED_BY, CREATED_DATE, LAST_UPDATE_DATE, SUBMITTED_DATE, STATUS, FINILIZED_DATE OF LCS_NAVIGATION_TREE_V
  
  When I run my page, the tree shows as many child nodes because child nodes.
  For example, I,

  project

  > Form9
  123 >
  > 456
  > 789
  > Form9
  123 >
  > 456
  > 789
  > Form9
  123 >
  > 456
  > 789
  
  Why the child node displays three times when it should only appear once. Any help will be greatly appreciated.
  I use Jdev 11.1.1.3.
  
  Oh and the keys are such...
  Status of parent - CreatedBy,
  Child - CreatedBy, status, FormName
  A grandchild - CreatedBy, status, FormName, FormId

  Hello

  Oh and the keys are such...

  Status of parent - CreatedBy,
  Child - CreatedBy, status, FormName
  A grandchild - CreatedBy, status, FormName FormId >

  I guess that your master / detail ViewLinks are based on the following attributes:
  Parent/child: CreatedBy, status
  Child/Grantchild: FormName CreatedBy, status,

  As the FormId is no attribute not part of the key to the child, you should include it in the motion of the child because it is SEPARATE from Basic. By inlcuding you get "Form9" tripled in the request of the child (because of 3 different FormId values corresponding to the "Form9").

  Open the query of the child as well, and try again:
  SELECT FORM_NAME, CREATED_BY, STATUS OF LCS_NAVIGATION_TREE_V
