• Hide columns in Table B, based on values LOV in another row of the table:

  Hello

  Jdev 12.2.1.0

  I have two tables A and B and I hide columns b based on the value of row of table A LOV. For example, I have a line in A table that has a column with the x, y, z values lov. Now, if I select the row in the table has and change the LOV to x, I had to hide some of the columns in the table (B) is there a way to get this feature? Any help would be appreciated.

  Thank you

  Assume:

  1 table a call "DepartmentId" column this column has LOV.

  B 2-table a column "ColumnInB" this column will be visible depending on the value of "DepartmentId".

  Try to do the following:

  1 - from data controls, drag "DepartmentId" attribute and drop it on the page as inputText then together make this inputText to false (you can remove it, but don't forget the corresponding binding in pageDef. not deleted).

  2. copy the value of the inputText which will be as "#{bindings." DepartmentId.inputValue}"and go to the"ColumnInB"column and visible property beyond the copied value.

  3 - the ColumnInB visible will be the condition as:

  4-set DepartmentId autoSubmit = 'true '.

  5-set table partialTriggers table B has id and id of DepartmentId LOV

• The sidebar to view the columns of the table without opening table

  In earlier versions of SQL developer, when I clicked on the button "expand" next to a table, it would be a list of columns that the table had without open the table in the main window. If I right click on the name of the table, there are open table.
  
  Is there a way to get 2.1 to return to this behavior?

  Open objects with a single click Explorer to be controlled through tools | Preferences | Database | ObjectViewer | Open the object by a simple click. I have it turned off and that it must be a double click on the name or right click and select open before the opening of the object browser. However, even with this, I need to click on the name of the object (not the 'expand' button) before the object viewer opens. By clicking on the button "expand" always expands the list of columns and open object viewer regardless of the value of preference.

• Columns of the table must have a header, or by the attribute "headerText"...

  With the help of JDev 11.1.1.3; get the design above time warning on pages where I have a table and don't need a column header (because for example, there is only 1 column and a section through another component header is sufficient), so empty on the column headerText property. The table appears fine without the header line and otherwise works fine, but I get the warning of design time. Is there a way to get around this? How is it is usually without warning?
  
  Thank you

  robli,

  This warning can be disabled if you wish (it is just a warning and not an error, after all). To do this, open the Preferences dialog box in JDev (Tools-> preferences), expand the category to Audit, and then click profiles. In the rules tab, expand the category of "Accessibility rules faces of ADF" and disable the rule "check that the columns of the table have the headers".

  The fact that the rule is in the section "accessibility" means that your approach to set the header text that can also cause problems if a sighted user needs to use your application with a screen reader, but I can't comment further on the impact of your approach.

  You can always ignore the warning as well.

  Best,

  UPDATE tablesubtype
     SET SUBTYPES  = TRIM (SUBTYPES);
  

  RTRIM do it alone will not be enough coz it takes away only right spaces and NOT left those.
  I guess in your case do a PLATE will be more advantageous to be safe and avoid left spaces in the future.

  For the intermediate spaces... try this.

  UPDATE tablesubtype
     SET SUBTYPES  = REGEXP_REPLACE (SUBTYPES, ' ', '');

• Unable to add a new column to the table of the LCD? Option, just usually add it.

  I have a form of LCD with a table in it. Im trying to simply add a new column to the table. The option is there, but the column appear just after clicking Add the column to the left. I selected a column, right click the space > insert > column to the left. But the habit intsert. The object table properties tab shows lines and colum numbers, but they are grey.

  It is a dynamic array, where a new line can be inserted using a button. Is that the dynamic nature of the question? ID hate to cancel all the flow dynamics and programming just to add a column, and then reapply them all.
  
  Thank you!

  Hello

  You do not add the columns in the object > palette (screenshot 2) of the Table. I suspect that the problem is that it is not enough on the page (in the content area) to add the column. In the screenshot 1, if you look at the width of the column highlighted from the space to the right of the table, you will see that a column can be added due to restrictions of space.

  Reduce the width of the column highlighted (temporarily), and then add a column. Once added, you can resize the columns to match the width of the page.

  Hope that helps,

• How to dynamically add columns to the table

  Hi all

  I'm new to ADF and need help on sub condition.

  We have created a ViewObject on the EMPLOYEE table that has under columns:

  EMP_ID,

  EMP_NAME,

  DEPARTMENT,

  COST_CENTER,

  BUSINESS_UNIT

  COUNTRY

  GCODE

  We need to create a page in the ADF with employee table to show only below the columns

  EMP_ID,

  EMP_NAME,

  DEPARTMENT,

  COST_CENTER

  Later, if necessary user should be able to add other columns to the page dynamically.

  Can you please advice on how to implement this feature.

  Thank you.

  Kind regards

  Vidya

  Hello.

  There could be a simple solution, which is to use the component PanelCollection.

  Drag ' drop your VO to a page and create a Table with all the attributes.

  For columns that emp_id, emp_name, cost_center, set the Visible property to false.

  Put the PanelCollection component on your page and drag your table inside.

  When you run the page you will see the view menu in the upper left corner of the table above. You can show/hide columns in this menu.
