How do i keep my table row selected when i come back to the same page?

I have have the following issue.
I have a table with many rows. I select one row and click the button which takes me to another page. From that page when i click the back button which takes me back to previous page but the problem is that the row is no longer selected. How would i fix this problem?
Any idea, suggestion or sample code will be appreciated.
Thanks
Nahman

Here you go..
1. To Get the selected Rows:
DATA: TV TYPE REF TO CL_HTMLB_TABLEVIEW,
 LT_FORMS TYPE TIHTTPNVP,
 TABLE_EVENT TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.
 tv ?= CL_HTMLB_MANAGER=>GET_DATA( request = request
 name = 'tableView'
 id = 'tvX' ).
 IF tv IS NOT INITIAL.
 table_event = tv->data.
 clear selectedRowIndexTable.
 selectedRowIndexTable = table_event->PREVSELECTEDROWINDEXTABLE.
 if table_event->event_type eq CL_HTMLB_EVENT_TABLEVIEW=>CO_ROW_SELECTION.
 read table selectedRowIndexTable with key table_line = table_event->ROW_INDEX
 transporting no fields.
 if sy-subrc eq 0.
 delete selectedRowIndexTable index sy-tabix.
 else.
 field-symbols type i.
 append initial line to selectedRowIndexTable assigning .
 = table_event->ROW_INDEX.
 endif.
 endif.
 ENDIF.
ENDIF.
Page attribute:
selectedRowIndexTable TYPE INT4_TABLE
2. To store the selected row index into Server side cookie...
 CALL METHOD CL_BSP_SERVER_SIDE_COOKIE=>SET_SERVER_COOKIE
 EXPORTING
 NAME = 'select_row'
 APPLICATION_NAME = 'NONE'
 APPLICATION_NAMESPACE = 'NONE'
 USERNAME = SY-UNAME
 SESSION_ID = 'NONE'
 DATA_VALUE = selectedRowIndexTable
 DATA_NAME = 'sbsp'
 EXPIRY_TIME_REL = 3600.
3. Get the value from Server side cookie..
 CALL METHOD CL_BSP_SERVER_SIDE_COOKIE=>GET_SERVER_COOKIE
 EXPORTING
 NAME = 'select_row'
 APPLICATION_NAME = 'NONE'
 APPLICATION_NAMESPACE = 'NONE'
 USERNAME = SY-UNAME
 SESSION_ID = 'NONE'
 DATA_NAME = 'sbsp'
 CHANGING
 DATA_VALUE = selectedRowIndexTable.
Hope this will help you...

What Mac model do you have? You might be able to upgrade the OS to Tiger 10.4 or Leopard 10.5.
Even browsers for Tiger 10.4 will get the update message.
You could try a newer browser than Safari, which is obsolete, by downloading Firefox v2.0.0.20 at http://www.oldapps.com/mac/firefox.php

How an INDEX of a Table got selected when a SELECT query hits the Database

Hi All,
How an Index got selected when a SELECT query hits the Database Table.
My SELECT query is as ahown below.
    SELECT ebeln ebelp matnr FROM ekpo
                   APPENDING TABLE i_ebeln
                   FOR ALL ENTRIES IN i_mara_01

The fields in the INDEX of the Table EKPO should be in the same sequence as in the WHERE clasuse?
Regards,

Hi,
You minimize the size of the result set by using the WHERE and HAVING clauses. To increase the efficiency of these clauses, you should formulate them to fit with the database table indexes.
Database Indexes
Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
The primary index is always created automatically in the R/3 System. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE. If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVING clause, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.

I went to the apple store and got my laptop looked over by a technician who then told me that the hard drive was broken, which was the reason why it was doing so. It's best to take it to the store and get a good decision on what's wrong with it and get the solution. I hope this helps.

How to increment an element in an array and put it back in the same array?

I have an array of values generated by another part of my program. My goal is to count the number of occurences for each integer value in the array and put these values in a new array. This new array will be a histogram of the input array. My approach is to do auto-indexing with a for loop. In the loop I use a "index array" to get the current value of the histogram array and a "replace array subset" to update the array element with "current+1". The problem is that when I wire the output of the "replace array subset" VI back to its input, I get a wire error. I guess I cannot wire it like that, but what should I do? Is there a completely different approach to do this that
is more elegant?
Thanks for your help!
Benoit

Hi Benoit,
I believe the thing that's missing is a shift register.
Right-click on the edge of your "For loop" and select add shift register.
Wire an initialized array to the shift register left terminal before entering the "for loop". Wire from this same terminal (inside the loop) as the source of the info used in your "index array" and replace array. The results of these two operations (just the way you are doing it now) gets wired to the "right terminal" of the shift register (inside the loop).
What ever you stuff into the right terminal, gets returned via the left terminal on the next iteration of the loop. When the loop is done, your final array of counts can be accessed by wiring from the "right terminal" (outside the loop).

Upon updating desktop keeps asking to restart and when I do, I get the same thing....over and over. What gives?

I tried to update Firefox. Everything went well until restarting computer. Result was nothing....got the same as I had before. Each time I tried to open Firefox, I got message to restart computer to complete installation of update. This goes on over and over. I have tried to uninstall Firefox using Control Panel and I get same results.....a message to restart the computer and this repeats itself also.

You can try to boot the computer in Safe mode (press F8 on the boot screen) to see if that allows to remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) if you can't uninstall Firefox or remove/rename that folder in regular mode.

Multiple details table on the same page

Newbi to APEX. Can I have muliple details table for update/insert in tabular format on the same page with the same master? Thanks!

In the meantime, I can answer to your questions:
· Why does JHeadstart not make use of the UIX-Struts integration (see Chapter 15 of the UIX developers Guide)?This has been done to allow the same page to be run both with Struts and MVC Framework, without needing to change the page. Using the UIX-Struts integration would have made the pages 'controller aware'.
· How do you specify which columns/attributes in a Table Layout are sortable?As far as generation is concerned, you can only specify the whole table to be sortable. In case of UIX you can post-gen modify the <sortableHeader> tag of each column separately. In case of JSP you can remove the <a href> tag for each column that you do not want to sort on.

Two forms that update differrent tables on the same page?

I tried to add two forms that update different tables on to one page.
Problem is when I do that the forms gives me an error saying the field does not exist. It's like it is trying to update one table with the other tables fields.
As an example Say I have one forms that is for people table and another one that is the Jobs table.
When I go to update the people table, it sends the data for the jobs fields too I get an error like the field job description does not exist.
I have two different forms for these and everything.
I would hope it is possible to have two forms that update different tables on the same page.

I was trying the exact same thing, but i managed to work round it by setting the steps to hide one region, so the user would enter the form see one region submit the region then direct back to the same page with the different region visible and the original hidden.
I don't know if this would be acceptable for you...

Small issue with custom table cell editor and unwanted table row selection

I'm using a custom table cell editor to display a JTree. Thing i notice is that when i select a value in the tree pop-up, the pop-up closes (as it should) but then every table row, from the editing row to the row behind the pop-up when i selected the value becomes highlighted. I'm thinking this is a focus issue, but it thought i took care of that. To clairfy, look at this: Before . Notice how the "Straightening" tree item is roughly above the "Stock Thickness" table row? When i select Straightening, this is what happens to my table: After .

As I said, you have to have empty context elements before additional rows will be open for input.
For instance if you want to start with 5 rows available for input do the following to your internal table that you will bind:
data itab type standard table of sflight.
do 5 times.
append initial line to itab.
enddo.
context_node->bind_table( itab ).
The other option if you need n number of rows is to add a button to the table toolbar for adding more rows. When this button is pressed, you add a new context element to the node - thereby creating a new empty row in the table.

Hi Soubhik,
I have added two additional columns for each internal table.

How to view data in tables by selecting the synonym from the database objec

I could not figure out how to view data in tables by selecting the synonym from the database objects navigation tree. I had to first choose the synonym, view the details of the synonym to determine the table name, and then select the table from the database objects tree. Is this the only way available?

This functionality currently does not exist. I don't see it on the 1.1 statement of direction either, so perhaps someone from Oracle can give some insight as to when this could be expected.
