ExportCollectionAction causes current rows values to be copied in the first row of the table
Greetings experts,
I use JDev 11.1.2.3
I'm facing a really strange behavior of the exportCollectionActionListener. I have a table, and for each row of this table, a link, which calls a popUp. This popUp shows the history of this selected record changes (means it displays the data from another table/VO, which keeps the history of the first one) in a table. I have a button which calls the exportCollection for this second table. When i press it, an excel file is generated and downloaded, and that's all fine untill now. If there wasn't any record in this table, and o go back to the first one, pressing the submit button doesn't track any changes. But if there where any records in that history table (always talking about the history of the current row) , get back to the first one and press Submit, than the very first row of the firs table, gets all it's values set as the last row of the second table, as it is copied from one to the other. I have to press Rollback to get it back into normal ( note that the popUp has it's CancelListener invoke a Rollback operation from a backing bean).
Why is this happening?
Thanks in advance
Hi Frank,
Well, that's it. No code is involved in this process, that's why i'm asking here. The only code invoked in here is that of the CancelListener of the popUp, and i've inserted it because of this problem, but it didn't resolve anything.
As per other code, i have another button which invokes code to generate and download a Jasper Report, in Pdf format. This has nothing to do with the exportCollection. Different buttons, different beans containing obviously different code. Further more, this behavior doesn't happen when i download the pdf (press the other button)
As per the popUp, there is just a link in each row of the main table, which has a showPopUpBehavior, which calls this popUp, containing the second table.
Note: if i download the pdf or do not do any operation with the popUp (i.e. just close it after it is opened) that behavior doesn't occur.
This is the source of the popUp, i've just removed the columns as it would take too much space in here:

How to use the first row function value for the rest of records
Hi all,
I am having a select statement like this. We are calling function enabled for each row. So it is taking
time. As per our bussiness logic, we can use what the function 'enabled' will give for the first row to
other rows also. so that we can avoid calling the function 'enabled' next row onwars.
Before
SELECT
decode(enabled(col1, col2, col3),'TRUE','xxx', col4),
decode(enabled(col1, col2, col3),'TRUE','xxx', col5),
decode(enabled(col1, col2, col3),'TRUE','xxx', col6),
decode(enabled(col1, col2, col3),'TRUE','xxx', col7),
decode(enabled(col1, col2, col3),'TRUE','xxx', col8),
from
table1 t1, table2 t2 where t1.col1 = t2.col1
After
SELECT
decode(enabled(col1, col2, col3),'TRUE','xxx', col4),
decode('true/false','TRUE','xxx', col5), --Here 'true/false' is the first row value after calling the function 'enabled'
decode('true/false','TRUE','xxx', col6),
decode('true/false','TRUE','xxx', col7),
decode('true/false','TRUE','xxx', col8),
from
table1 t1, table2 t2 where t1.col1 = t2.col1
Any thoughts on this, how to implement this logic
Thanks,
PalIt's not clear where col1, col2, col3... etc. come from, so I've assumed they're in table1.
with table1_X as (select enabled(col1, col2, col3) as enbl
,col1, col2, col3, col4, col5, col6, col7, col8
from table1)
SELECT decode(t1.enbl,'TRUE','xxx', col4)
,decode(t1.enbl,'TRUE','xxx', col5)
,decode(t1.enbl,'TRUE','xxx', col6),
,decode(t1.enbl,'TRUE','xxx', col7),
,decode(t1.enbl,'TRUE','xxx', col8),
from table1_x t1 join table2 t2 on (t1.col1 = t2.col1)p.s. you'd be better leaving out the enabled function altogether and incorporating the logic of the function directly in the SQL, and then you would be avoiding any context switching which will clearly impact performance on any large amount of data.

Worklist table ponits to the first row after copy row
Hi experts,
We have installed ESS BP 1.41 into EP version 7.02. Now we found one issue in the ESS Working Time application screen.
The screen has an option of copying rows from Worklist Table on top to the bottom table having Weekly/Daily view.
The problem is if we choose recoreds from the top table and press the button 'Copy Rows' the table gets re-sorted and again points to the first row.
When there are hundreds of entries in that table, it becomes difficult for the user to see the rows selected for copy immediately after pressing the Copy Rows button.
Can anyone help to stop this sorting.
Regards
ArindamHi Siddharth,
many thanks for your reply. One doubt in BP 1.41, it is a WD java application, but the note you suggested, talks about the Ehp5 version which is in WD abap. Can you please re check and confirm.

Grand total level of the percentage column giving value from the first row of column
Hi Guys,
I have a requirement like to show the percentage value which the calculation of two columns , in the grand total level .
I think it can be achievaable by giving the aggregation rule for that column as Server complex Aggregate .
eg.
Fiscal Year Department subdepartment Total cost Sub Department cost % cost
2011 Edu Books 500 50 10
2011 Edu Note Book 200 100 50
2011 Edu Furniture 300 30 10
2011 Edu 1000 180 18
Grand Total
Ideally it should come like as above ..but the problem with me that ,it showing correct value for all the rows ,but at the grand total level it's taking the value of % cost from the first row . like below..
2011 Edu 1000 180 10
Grand Total
I have calculated the % cost column in the answer itself as (Sub Department cost /Total Cost )
where the
Aggregation rule for the columns given are
Total Cost - Sum ,Sub Dep Cost - Sum, % Cost - Server Complex Aggregate
So plz suggest me any Idea to achieve this ..Thanks in advance.Give the agg. as avg for % field.
Best of Luck,

Infopath submit button only works for the first row in a repeating table
Hi, I have a InfoPath Email submit button issue I could not figure out. I have a master/detail repeating table in my form, and one of fields is "EmailAddress" which shows customer's email address. I created a submit button and put the "EmailAddress"
field to "TO" object. When I tested it, the submit button only would return the first row of emailaddress from the repeating table, but not the rest of it..
What I want is when I highlighted a customer, and click the submit button, the current customer's email address would show up in "TO" list. I did some research and saw some suggestions about using current() function. So I put current() in the front,
like this:
current()/dfs:dataFields/d:vw_HZLeadLists/@EmailAddress
Still not working..Just return the first record of emailaddress from master repeating table... Does anyone know what's going on here? Thanks a lot!Hello,
Use double eval to get all rows values. See my reply for more information in below thread:
eval(eval(EmailAddress, 'concat(ToField, ";")'), "..")

Show balances only at the first row in Discoverer.
I have a discoverer report based on Oracle GL module. I'm reporting the balances @ segment1,2&3 which gives Journal date, Begining balance , Journal amount and Ending balances. I'm able to pull in all the data. But the user wants enters the parameter as From period, To period and the segment1,2&3. Here is the data which is showing in my report currently.

user wants see the beginning balance only @ the first period. He is not interested in showing up at each and every line.
Then ending balance is sum of the begining balance which is at the first line and sum of all the journal amount which should show up at the last line.
I don't know how to show begining only at the first period and ending balance at the last row. Please help!!!
Edited by: PA1B on Feb 18, 2010 11:54 AM
Edited by: PA1B on Feb 18, 2010 11:57 AMMaybe you would come up with a custom folder that unions the GL Balance table to the GL JE Lines table? You would have to union a begiining balance entry to the JE detail. Not sure you would need an ending balance record. The beginning balance entry would have the first day of the month as its journal date value as part of the union coding, and journal name NULL. So that hopefully it will sort out as the first entry for the period. Though even that still provides an issue with crossing over multliple periods. You would have to add conditions that say that select the NULL journal name entry only if the journal date = the begin period begin date. Or as part of the union process you could create a new column with a flag for balance (Y for the beginning balance table records and N for the detail JE lines records) and use that new column for editing along with the begin date of the selected date range. Just trying to toss out some ideas here. I myself have never had to do sometihng like this, so I don't have a proven method to accomplish this. But think back to what happens when you join tables with SQL. You are getting a record today with begin balance, je detail line amount, and end balance, because you are joining gl balances to je detail. What you really want, I think is an SQL result that gives you the first result row being the beginning balance of the account of the user selected From Period, and then the following SQL row results are the detail JE rows. That way you only get the beginning balance to print one time, at the beginning, in the SAME column as the je detail amount, and you can then do a sum at the end of the account to sum up the Discoverer report detail rows that would give you an ending balance, again showing just one time for each account in the report. So you have to ask yourself this question - if I was writing this SQL myself (forget about Discoverer for the moment), how would I write it myself, manually, to get the desired result? Once you know how to code it manually, then that should give you a clue on how to set it up in Discovererer. Hope this helps a bit. Another thought - rather than use Discoverer, maybe look at the Oracle Finanacial Statement generator to handle this? Or maybe come up with some kind of materialized view (that might help performance, since GL detail lines table can get pretty darn large)? Keep in mind with a materialized view you get a non-current view of the data, so that won't work if you absolutely need to query over what is currently in the Oracle base tables. But if this is a once a month thing, you could refresh the materialized view after the period is closed and then the users can run the Discoverer report.
Good luck.

Lock the first row in an ordered table
Hi,
I have a table (TD_EVENTOS). I want to lock the row with te minimun value of a column (a timestamp called hora_evento) and some requirements of other columns. Then i build a cursor like this:
CURSOR c is select * from td_eventos where (...) order by hora_evento for update skip locked;
And then I make a fetch into this cursor and I get the row (locked) that I want. But i need the speedest way, and making that cursor it orders all rown in the table (when I only want the first row without lock) and when that table has 6000 or 7000 rows it wastes around 130 ms. My solution is to add to the WHERE a AND rownum < 50, and it only orders 50 rows (in 10 ms), but it orders 50 aleatory rows, and that`s not what I want.
Any solution faster?
Thanks!Sorry that wasn't clear of me and could be misleading. I didn't mean Oracle would have to do a full table scan, another access path such as an appropriate index scan would do. I was trying to get across that to do any kind of order or min or max, all records have to be investigated. Since the fact that you don't know a row is locked until you try to lock it, you clearly can't filter on it (it's not a data attribute).
Apologies for any confusion my earlier post might have caused.
The suggestion about using a sorted hash cluster still stands though, they are designed for FIFO queues.
Which reminds me - SKIP LOCKED is in fact undocumented but everybody knows that Oracle use it internally for doing AQ. Since it's undocumented, you don't know how it works, when it will work, when it won't and of course Oracle can turn around and say "we don't support this". -
The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

regulation_tester_7_loops.vi 244 KBI didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

Get only the first row for duplicate data
Hello,
I have the following situation...
I have a table called employees with column (re, name, function) where "re" is the primary key.
I have to import data inside this table using an xml file, the problem is that some employees can be repeated inside this xml, that means, I'll have repeated "re"'s, and this columns is primary key of my table.
To workaround, I've created a table called employees_tmp that has the same structed as employees, but without the constraint of primary key, on this way I can import the xml data inside the table employees_tmp.
What I need now is copy the data from employees_tmp to employess, but for the cases where "re" is repeated, I just want to copy the first row found.
Just an example:
EMPLOYEES_TMP
RE NAME FUNCTION
0987 GABRIEL ANALYST
0987 GABRIEL MANAGER
0978 RANIERI ANALYST
0875 RICHARD VICE-PRESIDENT
I want to copy the data to make employees looks like
EMPLOYEES
RE NAME FUNCTION
0987 GABRIEL ANALYST
0978 RANIERI ANALYST
0875 RICHARD VICE-PRESIDENT
How could I do this?
I really appreciate any help.
ThanksTry,
SELECT re, NAME, FUNCTION
FROM (SELECT re,
NAME,
FUNCTION,
ROW_NUMBER () OVER (PARTITION BY re ORDER BY NAME) rn
FROM employees_tmp)
WHERE rn = 1G. -
Getting the first row for each group
Hi Everyone,
I have a query which returns a number of rows, all of which are valid. What I need to do is to get the first row for each group and work with those records.
For example ...
client flight startairport destairport stops
A fl123 LGW BKK 2
A fl124 LHR BKK 5
B fl432 LGW XYZ 7
B fl432 MAN ABC 8
.... etc.
I would need to return one row for Client A and one row for Client B (etc.) but find that I can't use the MIN function because it would return the MIN value for each column (i.e. mix up the rows). I also can use the rownum=1 because this would only return one row rather than one row per group (i.e. per client).
I have been investigating and most postings seem to say that it needs a second query to look up the first row for each grouping. This is a solution which would not really be practical because my query is already quite complex and incorporating duplicate subqueries would just make the whole thing much to cumbersome.
So what I really new is a "MIN by group" or a "TOP by group" or a "ROWNUM=1 by group" function.
Can anyone help me with this? I'm sure that there must be a command to handle this.
Regards and any thanks,
Alan Searle
Cologne, GermanySomething like this:
select *
from (
select table1.*
row_number() over (partition by col1, col2 order by col3, col4) rn
from table1
where rn = 1In the "partition by" clause you place what you normally would "group by".
In the "order by" clause you define which will have row_number = 1.
Edit:
PS. The [url http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions004.htm#i81407]docs have more examples on using analytical functions ;-)

How to highlight the first row of a table
When entering the form, how do I get the first row of the table to be highlighted when it has not been selected yet? There is already data in the table. Thanks.
AllysonAny ideas on what would cause this NOT to work? I added this row right after the table is created and populated and it is still not highlighted when I enter the form. The snippet of code that does this is:
MyTableModel modelS = (MyTableModel)dataModel.get("S");
jTable1 = new JTable(modelS);
jTable1.setRowSelectionInterval(0,0);MyTableModel is this:
class MyTableModel extends DefaultTableModel {
public MyTableModel(Object[] columnNames, int numRows) {
super(columnNames, numRows);
public boolean isCellEditable(int row, int column) {
if (TableKey == 'S') {
if (column == 6) {
return false;
if (TableKey == 'O') {
if (column == 0 || column == 4 || column == 5) {
return false;
if (TableKey == 'P') {
return false;
return true;
}Can anyone help? Thanks.

Binding on an iterator always return the first row of the Children VO...
I have 3 pages:
A -- tree table bound to VO A; B is used to view the detail of a row selected inside the table; Inside B there is another table that contains the childrens VO of B. Select a row in the table will launch C to view the details of the children.
They are all in unbounded task flow.
From A to B, it works fine: Details of selected row inside the Table of A is showing correctly.
However, From B to C, selecting a row inside B, When C is launched, it always shows the content of the first row of the B's Children VO.
Any idea how this can be fixed? I want C page to show the details of the row selected in B's Table.
B's table is defined like this:

2.Only the first line can react to my manipulate, such as select one line and click delete button.
3.While choosing the other line-->click the command button, the page will be refreshed and the selected one will turned to the first line. (Now the selected row, will be the first row). And will do nothing ,and has no action with the command button.

deleteServerOper.execute();
return "deleteServer";
