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

• How to avoid to display a line blank in the table component

  Hello
  
  I create button and a table like in a read-only form.
  
  Whenever I click on Create Insert button, a pop-up window showing were the person enter the corresponding values and clicking on the "submit" button it should show changes in the table and clicking the Cancel button to return to the page.
  
  But even when I click on cancel there is always an empty line is indicated in the table. Is it possible to avoid it?
  
  Thanks in advance.

  In this case, you will need to delete the new created line. Link the button Cancel to a bean method of directly to the delete of the VO method, you used to create the line.

• Select at least 1 rank, even if the table is empty

  Hi all
  
  I've got table t1:
  

  with t1 as (
  select 1 as column1, 't' as column2 from dual
  )
  select * from t1 

  My need is to select at least 1 rank, even if the table is empty, for example:
  

  with t1 as (
  select 1 as column1, 't' as column2 from dual
  )
  select * from t1 where rownum = 0
  union all 
  select 0 as column1, '' as column2 from dual

  The problem is that I don't know the amount of columns and its data type. How can I make a dynamic query based on the current structure of table t1?

  Hello

  This looks like a job for an outer join:

  SELECT  t1.*
  FROM            dual
  LEFT OUTER JOIN t1    ON  1 = 1
  ;
  

  Because it is not reference individual columns from t1, you do not need to know what are the columns it, or what their data types.

• How to validate a list of button selection box record

  Hi, I have a form with a list of selection box required. If the user is not to seek a point of it I get ORA-01400: cannot insert NULL into error, but instead of this error, I have a javascript that could be used to send a message to the user before present, but have no idea where should I call go!
  
  Thanks for any info.

  Hi Iahmadi,
  You don't need to use javascript to do this, in fact, you can use apex integrated inline control validation to validate when no items selected. Try the following-

  For the list of selection in the LOV section, type-1 in the null value.
  Create a validation of levels element in the page that discusses the section. in the posting type select ITEM IN EXPRESSION 1 IS NOT CONTAINED in the EXPRESSION 2.

  It fires when the user click on the button without selecting any item in the drop-down list SAVE.

  Hope this helps,

  Kind regards

• Retrieve child line selected a tree table

  Hi all

  I have a tree table which includes two levels and one of the data in the column of the child node has a command link. Clicking on it calls a support bean method that tries to get the line that contains the command link that was clicked. The problem is, trying to get the line clicked (selected), it always returns the row parent of the node. I searched and followed by some examples of code, but it does not work for me.

  For example, if the table tree looks like, where X expands to show the children X 1 and X 2 lines:

  X

  L X 1

  L X 2

  Then clicking on the link to X 1 or X 2 will call code that returns the line for X.

  Here is the code in my grain of support:

     public void viewInspectionRecord(ActionEvent actionEvent) {
  
        RowKeySet rks = treeTable.getSelectedRowKeys(); 
        
        Iterator rksIterator = rks.iterator(); 
        
        if (rksIterator.hasNext()){ 
           List key = (List) rksIterator.next(); 
      
           JUCtrlHierBinding treeTableBinding = (JUCtrlHierBinding) ((CollectionModel) treeTable.getValue()).getWrappedData();     
           JUCtrlHierNodeBinding nodeBinding =  treeTableBinding.findNodeByKeyPath(key);     
           
           Row rowData = nodeBinding.getRow();
          
           if (rowData == null) {
               FacesMessage facesMessage = new FacesMessage("Please select an Inspection Record record to view details");
               FacesContext.getCurrentInstance().addMessage(null, facesMessage);
               
               return;
           }   
           
           Object irId = rowData.getAttribute("QarsInspectionRecordId");
           
           ...
    }
  

  rowData.getAttribute("QarsInspectionRecordId") eventually throw a NullPointerException because it is an attribute defined with the parent node and any children.

  Any ideas what's happening?

  Thank you

  You can use a column in the external table that contains all characters and a view that selects in the outer table, limiting the lines based on the length of the column that contains all characters, such as shown below.  You can create a separate view for those! = 87 if you want a list of releases.

• How to get the number of the row selected in the table

  Hello
  
  I did the data binding for the table using an arrayList. On some lines of a column, the button appears. When the button is clicked I want to know which line is clicked on the buttonm and want the index to use in the java file. Please help on how to do it.

  Hello

  On your table, you can have

  varStatus="rowStatus"
  

  and in the button, set the attribute as follows

  In your managed bean, you can access the index of the selected button

  public void myActionListener(ActionEvent e){
   System.out.println("index :" + e.getComponent().getAttributes().get("index"));
  }
  

  I hope this helps...!

• Problem with headphone selection if the table has only one row

  Hi all
  
  I have developed a table in which I use selection listener to perform a task when a line is selected.
  It works fine when I have more than 1 row in the table, but when I did that one line in the table, the listener of selection do not call the corresponding method in the bean.
  I understand this selection event is raised only when the line is changed, but in the case of use when only one line is there, what do I do to make the listener of selection work?
  
  The selection listener I wrote the code to make the line selected as current line and perform the required task.
  
  Please suggest a way out of this situation.
  
  Thanks in advance.

• 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

• How can I stretch/tilt a rectangular selection in the preview?

  Hi all

  Q: can you the proportions for a rectangular selection of cut-and - paste be unlocked?

  Formerly, in Snow Leopard 10.6.8 cut and paste a rectangular selection of an image in the preview has resulted a selection with eight points of click-and - drag: one at each corner and one on each side.  By clicking and dragging one of these licences stretching/tilt the value selected in any direction.

  Now, in the current version of El Capitan 10.11.3 preview, dragging these points only expands or collapses the selection and the aspect ratio is locked.  I have the impression I'm missing something very basic, but can't find any way to unlock the proportions for the selection in the drop-down menus or toolbars.

  A minor inconvenience, but boring, as the old function provided an extremely useful tool for making models quick and easy collage images that eventually became the graphic designs.

  Many thanks in advance,

• How to view a newly created line only in adf table?

  Hi all

  JDEV 12.1.3.0

  When you drag move a VO on a page as a table of adf, it displays all the lines available in the whole of lines. I want to display only the rows that are newly created in the user interface.

  I achieved this goal by creating a transient "RowStatus" attribute, which will be the State of the entity (0-1 new, unmodified, 2 - modified) and I filtered the table using this status of line by double clicking on the VO and specified a filtered attribute and the value. But the performance is very poor, because I think it makes even all records and only newly created filter lines.

  Is there another way optimized to achieve?

  How to achieve this programmatically?

  If I run VO.executeEmptyRowSet () when the page loads, the table is rendered empty at first, but after call CreateInsert operation, all rows are returned with this new line.

  You see the same behavior if you create lines programmatically (with: vo.createRow (); vo.insertRow (row)) instead of CreateInsert?

  If it does not then only "programmatic" option is probably to set where clause 1 = 2

• Get the first line selected on the CommandButton Click

  Hi guys,.
  My version of jdev is 11.1.1.5.0. I have table on my Page of Adf.

  you pass line value.right... so from value as link will not be work.try send as #{row.abc.value} go on setactionListener and so on. You pass the rank value.

• How could I NOT have a scene selection on the main Menu of the DVD?

  With the help of PRE 11.  I have a clip only, with no scenes (imported from a VHS).  When I try to make a DVD, it adds a default scene selection in the main menu of the DVD.  Since there is no 'scenes' (at least I think the scenes on a regular DVD), is anyway to remove/delete button on the main menu scene selection?  All the models that I have seen include the scene selection.

  In the same vein, I import a few VHS convert to DVD that will have several 'clips' on each of them.  For example, "Christmas 1988', ' holiday of summer 1989", etc.»  What I want to do with those, it is having the "clips" separated as a choice on the main Menu of the DVD, and have still no scene selection.

  Is this possible?   Also, I bought a Photoshop/Premiere Elements a few years and a couple of versions ago (because the sale price was the same as Photoshop Elements only).  I just watched the first after installation, didn't really use it, but it seemed to me that there are many more styles DVD.   Can I download other models from Adobe, or is that has come on the DVD there are all?  Is there anyway to make my own, because I don't see just a pattern of single color base type, it's too loud for me.

  Thank you

  I still don't know what you're doing. (Are making sure to turn off the option for the program adds automatically the markers of scene?)

  I just tested myself and certainly do not create a menu if you do not have menu scene marks.

  Can you post a screenshot of your timeline so we can have a look? Make sure that you press on the-key first, so that we see the entire timeline.
