• How to validate at least one line selected on the table?

  Hello world
  
  I have a requirement here to display a list of customers at a table "select unique" and a button to send the page. When the user clicks this button, I need to validate if there is a selected line in the table. What is the best approach tho do?
  I tried to validate it on actionListener in the click of a button, but even if I put adfFaces messages running, it does not appear on the screen and the page is still subject.
  
  Is the BPM 11 g context of the project, so I have to do this validation and 'Cancel' the submit, otherwise the data passes through the flow until the next activity.
  
  Maybe the real question is: how to undo a page submit during an actionListener?
  
  Thank you

  Hello

  Small correction to Vinod, tableBinidng.getSeelctedRowKeys () always returns non-null (returns empty set when nothing is selected), then use the tableBinidng.getSeelctedRowKeys () .getSize () to check if a line is selected or not (0-nothing selected).

  If you do not want to treat the action up to save if an option is selected, why don't you try disable the button until something is selected in the table?

  To disable a button when no rows selected, simply add after the disabled property of a button value update it based on the table (add partialTriggers to the table)

  I have listener custom selection for table to do things according to the selected line, but when the table has a single row of this line is automatically selected my interlocutor of choice is not triggered, so my question is how to accomplish that, initially, no row is selected in the table?

  Depends on the use case, but you can do this by deleting the attribute selectedRowKeys of the table.

• How can I exclude a level for the table of contents, but this amount as a bookmark?

  I know how to exclude a level for the table of contents (or rather include only levels I want to be included) and also how to create bookmarks from the table of contents entries, but how can I exclude a level for the table of contents, but always include it as a bookmark?

  Make 2 toc styles. One for the entries in the Bookmarks panel, you can generate a table of contents on the side of any page, and you must score in its definition to create bookmarks and other things that you use to build the table of contents for the visible part of your document to print. This should have unchecked the option create a bookmark in its definition.

  Not possible as your data model do not answer for him. As simple as that.

  If there is a need to determine an order or associate some time to an entity, then that should be part of the data model - and a relationship, or one or several attributes are necessary to represent this information. Your data model in this case is therefore unable to meet your requirements.

  If the requirements are valid, set the data model. In other words - your question has nothing to do with Oracle and nothing to do with the other pseudo columns in Oracle, the rowscn or the rowid. It is a question of pure data modeling. Nothing more.

• How to create a report based on the item selected from the list of selection?

  Hello

  I created a tables_LOV based on:

  Select table_name table_name user_tab_cols r, d

  where column_name like '% _type % '.

  Then I created a ListOfTables page element, display in a selection list and pointing to tables_LOV.

  I run the page, and I can choose the table I want in the drop-down list.

  How to create a report based on the selected element? (ex: select * from selected_table)

  Thanks in advance

  Salah

  Hi Salah,

  Allright, take a look at this page: http://apex.oracle.com/pls/apex/f?p=vincentdeelen:collection_report

  I think that simulates what you are trying to accomplish. I've implemented the simplest method I could think of.

  The report is based on a collection of apex. If you are not familiar with this, you should study the documentation: APEX_COLLECTION

  To recreate my example, you should:

  (1) create a report (interactive) on your collection

  SELECT *
     FROM APEX_collections
   WHERE collection_name = 'MY_COLLECTION'
  

  (2) create a selection list page_item for the tables that you want to display (in my case, this is called "P38_TABLES")

  (3) create a dynamic action that triggers on the evolution of your selection list page_item. Dynamic action must be a parade of PL/SQL procedure the following code:

  declare
    l_query varchar2(4000);
  begin
    l_query := 'select * from '||:P38_TABLES;
    if apex_collection.collection_exists
          ( p_collection_name => 'MY_COLLECTION' )
    then
      apex_collection.delete_collection
        ( p_collection_name => 'MY_COLLECTION' );
    end if;
  
    apex_collection.create_collection_from_query
      ( p_collection_name => 'MY_COLLECTION'
      , p_query           => l_query
      );
  end;
  

  Make sure that you add your page_item 'Page to send items' section.

  (4) add a real extra action that makes an update of the report area.

  Here are two photos describing the da:

• [ADF, JDev 12.1.3] How to hide menu items based on the logged in user

  Hallo,

  When the user logs on successfully, the applitacions led him to the main.jspx page.

  The main.jspx page has a menu bar that contains all of the available menus, submenus and menu items.

  After the connection, when the main.jspx page loads I would hide all the menus, submenus and menu items that the user is not qualified to see/use (I read the database).

  You kindly tell me which is the way the cleaner to achieve?

  Thank you

  Hello rohanwalia,

  Sorry, but I need more help

  I guess that the solution is to create a method in the AM who - reading form the database - returns a structure that indicates for each menu item should be visible or hidden.

  • How can I use the data returned by this method?
  • I call in a managed bean specifically dedicated to the management of the menu? Can I also use the already existing media bean, I created for the page?
  • What scope should have the bean?
  • Don't you think that it is better to define a 'visible' variable Boolean (initilized depending on the result of the AM method) for each menu item and how to bind the Visible property of each menu item to the variable respective in the bean in the bean?
  • Or I can loop the result of the method AM setting the Visible property of the menu items? In this case, I guess that all the menu items must be mapped into the bean by user interface variable. Am I wrong?
  • Is it not possible to write a method which, of the AM directly, hide the menus not necessary on the page (so without using a bean)?
  • In general, which are the correct always to hide menu items:
    • (1) before the page is sent to the browser (as "I can do it with PHP);
    • (2) once the page is loaded in the browser (as I can do it with JavaScript)?

  If you could give me some more detailed advice... I would be very happy.

  Thank you

  Federico

  (1) its best to make the treatment inside the method. You can return the parameters as normal java method.

  (2) Yes, you can use bean already exists in the project. But better to create a separate bean for this task of menu.

  (3) scope should be request unless you need to persist the attributes between requests.

  (4) Yes it is possible. You can define and initialize a Boolean variable with the results you get from the table based on the menu items should be made visible.

  (5) If you use the approach to point 4, then also you have to loop through the table menu items and set Boolean variables of bean. Yes you are right for the second part.

  (6) I'm not sure about this approach. How will you map it to your menu mode. It takes research.

  (7) before the page is loaded. I share with you links in above post with which you can do this.

  I hope this helps.

  Thank you

• How to hide a multiple selection of the TableRegion element dynamically

  Hello

  Try using the code below:

  (I found this on the blog of Mukul

  Oracle of Mukul technology blog: dynamically change multiselect for single select statement in table of the OAF)

  Hide Multiple selection

  OAAdvancedTableBean tabBean = (OAAdvancedTableBean) webBean.findIndexedChildRecursive ("[table item id]");

  Given that multiple selection is at the end, get the total-1 to remove

  int count = tabBean.getIndexedChildCount (pageContext.getRenderingContext ());

  System.out.println ("number of children" + count);

  tabBean.removeIndexedChild(count-1);

• How to create a 2nd selection using the elliptical selection tool

  I try to create the outer edges darker IRIS with the elliptical selection tool. I am trying to elect the iris and then create another selection of the iris 2nd with the elliptical selection tool.

But for some reason, the tool does not work and I'm going through the procedure of Scott Kelby said to do. After I have selective elliptical selection tool, I do a circular selection around the Iris then after I adjust the size of the selection, I go to the "Sélection" menu and choose "MAKE SELECTION" then, command - click a selection handle to help it adapt to the Iris; Then I press on and hold down the SHIFT key and select the other Iris.

• How can single checkbox can be selected in the table with Boolean checkboxes?

  I have a table editable ADF where an attribute is a Boolean checkbox... and stores the value with Y or N.
  
  Is there a way where the single checkbox must be selected at time of posting?
  
  For example, in the case its a table of responses to a choice unique to an application of Questionnaire, Question by adding new responses to the table..., the user inserts 3 rows (answers)... then the Boolean checkbox for only one of these 3 rows can be verified.
  
  Thank you
  DJ

  Since you have an attribute that has the "Y" or "n" for each line.
  When the user selects a line, you must deselect the other lines using the value change listener pro-grammatically.
  If the number of rows is large, it could be performance intensive.

  Thank you
