How to disable a Column for a particular row in Advanced Tables

Hi All,
We are using an Advanced Table for search criteria. Our requirement demands to disable a column (we are using messagechoice item in that column) for only first row. We use standard Add Another Row functionality to add the rows.For the remaining rows it (message choice) should be enabled. Can anyone help me to solve.

Sundeep

You can either use a Switcher or OADataBoundVariables for this.
Please see the section OADataBoundVariable in the dev guide. Based on certain View Attribute value, you can set the specific column in the table as Read Only.
Switcher can be very similar too. Decide an Attribute for the Switcher and make sure the first row (which you want to disable) has some specific value. All other rows should have some other value. Decode can help you here. Then you would need to create two cases. Under the specific to first row, have a read only item. For the other case, have an enterable item. A little read through of the Switcher chapter in the Dev guide would clarify the doubts if any.

Sumit

How to disable Transactional Iview for a particular user in portal

Hi Experts,
I have a scenario
i have created a user group for all the employees and assigned all the transactional roles to it, now the issue is they wanted to disable the Transactional Iview to particular user for a certain period and enable it later on, how is it possible?
As per my knowledge we have to assign that particular Role individually to all the user, instead of user group and make the iview invisible when required.
Instead of this is there any other Easy Method that i can approach the issue easily?
Thanks Inadvance
Siva

Hi Siva,
You can have two types of groups: one Group with users having access to transactional iview and another devoid of this access.
You can assign users to group with transactional role and vice versa. By the way of user groups, we will have more control over the transaction role access.

How to disable u201Csticky sessionu201D for the particular web application?

Hi All,
Is there a possibility to disable so called u201Csticky sessionu201D for the particular web application? We have deployed a WAR file with the Axis 1.4 based web service into SAP NW 7.1. The web service works fine but when the client makes SOAP request the server creates a so-called u201Cstickyu201D HTTP session with the default (30 minutes) timeout. Such u201Csessionsu201D are created on each SOAP request from the same client. The maximum number for Java Web Sessions (SAP Management Console) is 1000. After a while the clients start getting the u201C503 Service not availableu201D errors:
503 Service not available.
Error: -6
Version: 7010
Component: ICM Java
Date/Time: Tue Mar 03 14:30:12 2009
Module: http_j2ee2.c
Line: 1166
Server: XXXXXXXXXXX
Error Tag:
Detail: server overload: no more sessions available
The only way to improve the situation we found so far was to set session timeout to 1 minute. That u201Csticky sessionu201D will still be created, though.
This is a testing environment and we do not use any hardware/software loadbalancer.
Any help/advice is appreciated. (Please let me know if you need more information.)
Thanks,
Dmitry Vasilenko

The practical workaround we finally come up with for this problem was to create a servlet filter and map it to the AxisServlet. The servlet filter will invalidate the HTTP session and effectively destroy the sticky session created by the server on each SOAP request.
Here is the fragment from the web.xml
<filter>
<filter-name>StickySessionFilter</filter-name>
<filter-class>com.xxxxx.xxxxx.xxxx.services.StickySessionFilter</filter-class>
</filter>
<filter-mapping>
<filter-name> StickySessionFilter </filter-name>
<servlet-name>AxisServlet</servlet-name>
</filter-mapping>
<servlet>
<servlet-name>AxisServlet</servlet-name>
<servlet-class>org.apache.axis.transport.http.AxisServlet</servlet-class>
</servlet>
The doFilter() method looks like this:
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
 try {
 chain.doFilter(request, response);
 } finally {
 javax.servlet.http.HttpServletRequest httpRequest = (javax.servlet.http.HttpServletRequest)request;
 javax.servlet.http.HttpSession session = httpRequest.getSession();
 session.invalidate();
Thanks,

How to detect a deadlock for a particular row?

Please give us the solution of subject problem.
Thanks & regards,

Exactly my point..
What you want to do after detecting it .. either throw an exception
or
notify the user that there 's a deadlock.
So for first case let oracle throw an exception
or
for second catch the exception and do what ever you want to do..
see below for ex..
DECLARE
   deadlock_detected EXCEPTION;
   PRAGMA EXCEPTION_INIT(deadlock_detected, -60);
BEGIN
   ... -- Some operation that causes an ORA-00060 error
EXCEPTION
   WHEN deadlock_detected THEN
      -- handle the error
END;

How to diasble selection for particular rows in a Table?

im currently working on a multiple select table.. i need to disable the checkbox for some particular rows. How can i get runtime control over that cell??

To disable one or more rows of single or multiple selection in your table, add the following code to your controller processRequest method:
OATableBean tableBean = ...;
tableBean.setSelectionDisabledBindingAttr("Disabled");
In the example above, "Disabled" represents the Boolean view attribute that returns 1/"Y" if one or more rows is (are) to be disabled, otherwise it returns 0/"N". The view attribute "Disabled" must belong to the same view object as the one associated with the table items.
If its an advanced table, use the same method on OAAdvancedTableBean instead.

How to disable the validity of a particular Role for 100 users, in a single

Hi
How to disable the validity of a particular Role
which is assigned to 100 users. (disabling the role of change the validity of the role )
at present am doing manually, by entering into each user and changing the validity of the role
Thanks.

> How to disable the validity of a particular Role for 100 users, in a single ...
... shot?
Assign a reference user to the 100+ users and create events in the factory calendar which assigns and removes the role from the reference user only.
The downside is that it is not scalable for many of the same concepts at the same time, because a dialog user can at one logon time only have one reference user assigned to them.

How to disable a column in Advance Table

Hi All,
I have an advance table, for which one of the column is MessageTextInput I want to disable this column programatically on certain condition for a particular row, is this should be implemented by switcher else is there a better way.
Thanks in advance

switcher is the best way to implement this problem.
You can also use SPEL expression, which is very easy to implement.
Eg,
Set the SPEL expression for readOnly property as ${ReadOnlyFlag} // where readOnlyflag is a boolean attribute in the VO of respective region.

How to disable JTable Column Dragging (only single column)

How could i disable a single column from being dragged in JTable?
I need to fix the first column from being dragged in JTable and all other columns except the first can be dragged. how would i accomplish this task ?
well, i know how to fix all column in jtable from being dragged using
table.getTableHeader().setReorderingAllowed(false);But dont know how to fix only a single column. is there any method for doing this. or i have to implement any other logic?
Please help me !
Thanks

The question is why do you have this requirement. I figure if the user wants to reorder the colum, let them, the table won't break.
Maybe something like this would be acceptable:
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class FixedColumnScrollPane extends JScrollPane
 public FixedColumnScrollPane(JTable main, int fixedColumns)
 super( main );
 // Use the table to create a new table sharing
 // the DataModel and ListSelectionModel
 JTable fixed = new JTable( main.getModel() );
 fixed.setFocusable( false );
 fixed.setSelectionModel( main.getSelectionModel() );
 fixed.getTableHeader().setReorderingAllowed( false );
// fixed.getTableHeader().setResizingAllowed( false );
 fixed.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
 main.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
 // Remove the fixed columns from the main table
 for (int i = 0; i < fixedColumns; i++)
 TableColumnModel columnModel = main.getColumnModel();
 columnModel.removeColumn( columnModel.getColumn( 0 ) );
 // Remove the non-fixed columns from the fixed table
 while (fixed.getColumnCount() > fixedColumns)
 TableColumnModel columnModel = fixed.getColumnModel();
 columnModel.removeColumn( columnModel.getColumn( fixedColumns ) );
 // Add the fixed table to the scroll pane
 fixed.setPreferredScrollableViewportSize(fixed.getPreferredSize());
 setRowHeaderView( fixed );
 setCorner(JScrollPane.UPPER_LEFT_CORNER, fixed.getTableHeader());
 public static void main(String[] args)
 // Build your table normally
 JTable table = new JTable(10, 8);
 table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
 JScrollPane scrollPane= new FixedColumnScrollPane(table, 1 );
 JFrame frame = new JFrame("Table Fixed Column Demo");
 frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
 frame.getContentPane().add( scrollPane );
 frame.setSize(400, 300);
 frame.setVisible(true);
}Or maybe you should be using a Row Header. A row header is like the column header of JTable. It remains fixed on the left side of the scroll pane. Search the forum for examples using "setrowheaderview".

How to set fire action event for particular rows in a table

HI All,
I have a requirement in which I want to set fire action event for particular rows in a table based on some condition.
The table has columns like fullname,employee id etc.
So i want to set fire action event for particulars rows only which will saisfy some condition.

Atanu,
Your approach(setting fire action for few rows) seems not possible. Better to go ahead with workaround.
Do you want this functionality in processRequest(while page loading) or processFromRequest(on some event) method ? Give more explanation regd. your requirement ?
In either case loop through the rows and when your condition is met write the action to be performed in controller.

Anand

HOW TO: Add /manipulate columns for a GridControl

HOW TO: Add /manipulate columns for a GridControl when the columns (attributes) are from different entity objects.
This HOWTO describes the basic steps of using attributes from different entity objects for a GridControl.
One way you can create a GridControl which contain attributes from different entity objects is to create a view object and base it on the entity objects which contain
the desired attributes.
Here are the basic steps:
1.Create a new view object (or use an existing view object) by selecting File>New from the menu, clicking the Business Components tab and double-clicking
on the View Object icon.
2.In the View Object wizard change the name to something meaningful.
3.Select the entity objects you will base your view object on.
4.Nivigate to the attribute screen and select the attributes you would like to include in your view object from each entity object. At this point you can also create
a new attribute by clicking the "New" button. The new attribute can be a concatenation of other attributes, derived from a calculation etc.
5.In the query panel of the View Object wizard, click "Expert mode" and enter a query statement. You write complex queries such as decoding a set of attribute
values.
6.Add your newly to your newly created view object to the application module by double-clicking on the application module in the navigation pane and selecting
your view object from the list.
7.Create a new row set.
8.Bind row set to a query by editing their queryinfo property and selecting your view object and its attributes from the queryInfo pane.
9.Create a GridControl and bind it to the row set by editing the dataItemName property of the GridControl. Since the GridControl is bound at the row set level
all of the related attributes are automatically added.

Michael,
Are you intending this as a commercial solution or a work around?
To take an existing equivalent, one would build a view in the database tailored for each grid in an Oracle Forms application. Or a separate query layered over tables for each form/grid in a Delphi or Access application? Even if it is ninety nine percent the same over half a dozen forms/grids?
And now you've added a whole slew of "slightly different" rowSetInfos to maintain.
So if you wanted to add a column that needs to appear everywhere... you've just increased the workload multi-fold?
That would be a management nightmare, wouldn't it? Not to mention yet more performance cost and a slower system?
Hmmmm..... I'm not sure I like where this is headed... someone needs to do some convincing...
