• How to access the data in the row (text of children) in a pragmatic control tree?

  In LabVIEW 2010, I entered the data in row a tree with pragmatism control using the Add item and providing the child text table and the child tag for the line. When a row in the tree control is selected, I can get the line label in the Value property of the tree. But how do I access the data in the child text table when the line is selected? I can't seem to find a tree control property or method which will return data back.

  What I'm trying to do is: once a line in a tree is selected and a button is pressed, if the line tag is valid, I want to transfer all the data in row in another tree the same formatting. For this I need the data for the tree line and the line that was selected. I don't find a way to get access to these data of the line when it was composed in the tree.

  Can someone tell me how to access pragmatically the child text or row data in a tree control from a selected line in the tree? I have the label of the line, but how do I access data?

  Thank you for your help.

  Looking through numerous examples, I found how to do this using the properties ActiveItemRow and ActiveColNum, but I can't find these documented properties anywhere using LabVIEW. Even research through aid could not do anything about them.

  Where these important parameters are documented?

  Why they do not appear in the help?

  Are there other ways to access the data in the row (child text) form a selected line in a tree control?

• Casting error trying to access the tree liaison

  JDeveloper version 11.1.2.1.0
  
  java.util.ArrayList cannot be cast to oracle.jbo.uicli.binding.JUCtrlHierBinding
  
  Hi all
  
  I use the ADF Code corner (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/78-man-expanding-trees-treetables-354775.pdf) code to programmatically set the level of disclosure of the tree node when the page is rendered at the beginning. Property DisclosedRowKeys of the tree is #{viewScope.FieldPickerHandler.newDisclosedTreeKeys}. Below is the code for the handler method that is the cause of the problem. First of all, you can see that I commented on the original code of Frank on lines 5, 6 and 8 because for some reason, it did not find the component of the tree (always returned null). To remedy this, I put the tree component binding property to #{viewScope.FieldPickerHandler.jsfTree} so that the instance of the component available in the Manager and it seems to work. However, when typing code line 16 I get the exception of cast of class at the head of this post.
  
  Significant variation of the example Code corner, is my tree is based on a POJO model that is populated by a VO (as shown by Lucas Jellema http://technology.amis.nl/blog/2116/much-faster-adf-faces-tree-using-a-pojo-as-cache-based-on-read-only-view-object-showing-proper-leaf-nodes-again) program where my node set root, and each child node set, is declared as "nodes list < FieldPickerNode > = new ArrayList < FieldPickerNode > ();".
  
  Is the way the POJO tree is built that it is incompatible with the method of development of node Code corner? Can anyone suggest how I can change my bean handler code to work with POJO tree?
  
  Thank you
  
  Adrian
  
  PS the property Value of the tree is set on #{viewScope.FieldPickerHandler.treemodel} where treemodel is a property managed bean - I guess that means that my tree is not related to the ADF?

  Hello

  java.util.ArrayList cannot be cast to oracle.jbo.uicli.binding.JUCtrlHierBinding

  JUCtrlHierBinding is the model tree binding in the ADF, while if you are not using the ADF for the binding of the tree, its your tree model implementatuon, which in your case seems to be an ArrayList. If the code of the ADF Code corner is sort of by going through your custom implementation. You must cast to an ArrayList and get the data you want to work with out of this list

  We must look on what is the key of the row of each node. Then give you a clue on how to make the angle of ADF Code work for your example of the sample.

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

  Hello

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

• Convert data in hierarchal of hierarchical data for the creation of the tree

  Hi guys,.
  
  I tried to figure this out for about two days together now and I'm still stuck and I see no possible solution that does not involve a new creation of the table.
  I want to create a tree to navigate through projects and tasks, I use the demo "Task Manager" app, which I customized it a bit to fit my needs.
  
  Basically, I can't create the tree because the relationship between projects and tasks is not a hierarchical relationship, it's a relationship 1: n like this:
  
  __Projects__
  ID (PK)
  PROJECT NAME
  
  
  
  ___Tasks___
  ID (PK)
  Project (done FK reference Projects.ID)
  
  
  So what I have to do is to "force" this relationship 1: n with a hierarchical relationship by creating a query (view) that links the two tables into one and have 2 columns, I can use as ID and PARENT_ID for the creation of the tree.
  
  This is the data model:
  
  
  CREATE TABLE 'EBA_TASK_PROJECTS '.
  (NUMBER OF 'ID',
  'PROJECT_NAME' VARCHAR2 (255),
  "CREATED_ON" DATE NOT NULL ACTIVATE.
  'CREATED_BY' VARCHAR2 (255) NULL NOT ACTIVATE.

  It's good enough that this guy, hope you can help me with this. I'm really stuck on this and I'm about to give up.

  Hello

  I'd say you need a UNION rather than a JOIN.
  Something like:

  WITH project_task_view AS (

• How to use record group to insert data into the hierarchy tree?

  Hello

  -Transfer the data from the record group to the hierarchical
  -tree and bring it to display.

  END;
  
  
  Thank you
  
  
  David

  David,
  You get an error with your code? Looks like you took your example code help Forms. I don't really see a problem with the code, but the forms example gives an example of how create the record group used by the HTree so the Receiver General may be the cause of the problem. When I used the HTree, I used the FTREE. Procedure ADD_TREE_DATA to fill the tree. When I started working with HTree I created a wrapper package to simplify the process. You can watch how I work with the HTree in a demo that I published called: forms and how to: create a shape of the HIERARCHICAL tree.

  Hope this helps,

  (We have 10g. But in the table tree 11g have a different configuration. )
  
  Thank you...

  I think that if you want to limit the list of records shown at the first level of the tree to those without a father - you'll need create a VO that this query - and then add a viewlink to the full list.
  For example by using the employees table in the HR schema, which would be something like a VO with 'where manager_id is null' for the first level, as well as a link from there to the VO used to get other levels.

  Frank Nimphius-Oracle

  I have a work around for this bug to Oracle.  I have a version in 037 sample that actually works and that will sort the field date.  I'm ready to download a copy to replace the download version that is there if Oracle is listening.  The sample was there 5 years ago so it is regrettable that this bug still exists.

  That's what I did

  create beans with custom queryListener

  On the table

  change

  queryListener = "#{bindings.allEmployeesQuery.processQuery} '"

  TO

  queryListener = "#{queryListenerBean.processQuery} '"

  Add an additional field to the line which is a long value of the Date column.   In the queryListener I change the input filter on the value of long type instead of the date value.

  I do not display the column containing the value of long (time) in the table, but she must appear in the binding of the tree. (shuttles to the right)

  In the listener query

  • Read the filter value Date and read the value of time full, clear the value of the filter date
  • long time set in the filter
  • Run the query by call of the listener of the original request #{bindings.allEmployeesQuery.processQuery}
  • Set the date value to the value entered by the user
  • erase the value of long type

  Here is the code

  {} private void processQuery (QueryEvent queryEvent)

  Table richeTableau = (RichTable) queryEvent.getComponent ();

  FilterableQueryDescriptor filterQD = (FilterableQueryDescriptor) table.getFilterModel ();

  Card filterCriteria = filterQD.getFilterCriteria ();

  Date dt = (Date) filterCriteria.get ("hireDate");

  time of to of subject Date and filter on hireDateLong instead of column hireDate column

  containing the value of long type of date instead of the Date

  If (dt! = null) {}

  TM long = dt.getTime ();

  filterCriteria.put ("hireDateLong", tm);

  filterCriteria.put ("hireDate", null); This must be null or will not work

  }

  DCBindingContainer bc = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  Object execBinding = bc.findExecutableBinding ("allEmployeesQuery");

  does not perform a cast of the class internal oracle but another technique guided under

  does not work with POJO data control

  run the filter

  (ExecBinding) .processQuery (queryEvent) (FacesCtrlSearchBinding);

  This will fail

  invokeQueryEventMethodExpression ("#{bindings.allEmployeeesQuery.processQuery}",)

  restore the value of the filter if he continues to display in the QBE bar

  filterCriteria.put ("hireDate", dt);

  filterCriteria.put ("hireDateLong", null);

  }

• How can I migrate my old synchronization data to the new system when I signed in devices

  I just reformat the hard drive of my computer and reinstalled Windows and Linux. Now that I have installed and updated, Firefox wonder to migrate to the new synchronization system they have. Problem is, I still want to be able to connect to the old system just to be able to get my favorites so I can migrate to the new system.

  I always sync my key and the connection information for the old system, but I just want to know how to access it once for the information available to me. I can handle everything from there.

  Hello, in this case you'd probably have to use a workaround and download the previous firefox version, disable the automatic update for the moment (in options > advanced > update), bind it to the old account synchronization and upgrade after you successfully restore your data in this way...

  Install an older version of Firefox

• Adding items to the tree in an effective way

  Hello

  I am trying to add items in the tree.

  The problem I am facing is, I have to update the tree constantly and add elments.

  To add first items bit it takes less time, but as the tree grows the accumlated gets.

  Demo Vi is attached for reference.

  Any HELP WILL BE GREATFUL. (vi ATTACHED IS in 2009 version)

  First of all, 1% for calibration of time Windows is 'no difference '.

  But indeed, the update of the front panel is not the factor limiting here: this is the number of children-entries that create problems. So with zero children (as I did in my first test), to postpone the updates done grant you a huge performance increase as is the one and only overhead.

  In your case (100 children), defer updates is disabled the relevance as the method 'Add items' takes awhile.

  I agree that the performance impact is huge, maybe too big, to increase the number of children. But on the other hand, you must understand that you are dealing with arrays of cluster... is in fact a big effort for the memory manager to allocate enough memory, copy of things around and (internally) the deallocation of memory. It's the more data, the most important, this will create. Therefore, it will get slower the more data that you add. But certainly, the measure is surprisingly high.

  But nothing you can change.

  To the last comment: why do you need a tree that changes many times during execution while maintaining several 100ths of elements in any combination of parent/child?
