Single Selection tables

Hi all!
I created a new UIX screen (based on an existing one) with a table that has a single selection column (radio button). This table is displaying child datasource set information. My goal is to select one row and then send the key of the selected row to a new page which will display the details of it. The thing is that I cannot get the selected row from the table. When debugging the index variable is empty as if no row was selected. The funny thing is that a javascript validation passes with no problems but when I try to interact with the JHeadstart classes I get this error.
What should I do to pass the selected table row to JHeadstart?
Please let me know if you need more information
Regards
Maxi

Maxi,
You can generate this by creating a group with table-form layout.
If other parts of the system cannot be generated again, you could first create a separate application structure file with this group, and generate the required pages and entries in the service xml. You can then integrate the pages ans service content with the existing app.
This saves you time to figure it out yourself.

How to select a row in a single-select table view?

Hello folks,
I have a table view with a 'details' button. When a row is selected and 'details' is pressed, the table view disappears and a form view is displayed (like the toggle button in PCUI). I have implemented this using a navigation link. When I press 'cancel' in the form view, another navigation link takes the user back to the table view.
My problem is, when the table view reappears, there is no row selected (the row that was selected previously, is de-selected). How do I make sure that the row remains selected?
I tried using the collection_wrapper->mark() method in the inbound plug of the table view, but it works only for multi-select table.

Hi Masood,
Thanks for your reply.
I had already tried using MARK ( iv_index = lv_index ), but it did not work because the first statement in the MARK method is
check ME->MULTI_SELECT = ABAP_TRUE.
Mine is a single-select table. So, using the MARK of the iterator object, with either the IV_BO or the IV_INDEX parameter also does not work. Is there any other way for a table with single row selection?
Thanks!!!
Rohan.

2 single selection tables on the same page

I used the following great article:
http://blogs.sun.com/roller/page/winston?entry=single_selectable_row_table_component
to create a singlerow select table. But I want 2 of these tables on the same page of my tabset component.
On my page i have:
private TableSelectPhaseListener tablePhaseListener = new TableSelectPhaseListener();
public void setSelected(Object object) {
RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
if (rowKey != null) {
tablePhaseListener.setSelected(rowKey, object);
public Object getSelected(){
RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
return tablePhaseListener.getSelected(rowKey);
public Object getSelectedValue() {
RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
return (rowKey != null) ? rowKey.getRowId() : null;
public boolean getSelectedState() {
RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
return tablePhaseListener.isSelected(rowKey);
but when I added the second table, I had to add the duplicate the above 4 methods, changing currentRow to currentRow2 and tablePhaseListener to tablePhaseListener2, and changing the method names. I also had to make these updates in 2 other places---on the JSP code, as well as in the JavaScript!! For just 2 tables this isn't too bad, but with more tables having to synchronize everything could get real ugly real fast. Am I doing something wrong?
Also,
It seems to work, however my IE browser is still reporting some minor Javascript errors that I don't get when I had only 1 single-row select table
Thanks,
-DM

I also went the route of duplicating all methods for the single-selectable row in a table.
I have at most on my pages two tables with selectable rows and I have not run into any javascript issues.
I have had a problem when I rename my tables from "table1" etc. The row selection does not work as well when I give my table objects meaningful names. I have not had the time to dig in and discover why.

How to get selected record details when single selection is used in a table

Hi All,
Inside a query region I have created a table using region wizard,for this table I have added a singleSelection Item. What I want is , on selection of a particular record i want to update or view that record in a new page , for this I have added update and view icons in each row.
But I am unable to get the particular selected record
OATableBean tableBean = (OATableBean)webBean.findChildRecursive("ResultTableRN");
OASingleSelectionBean singleSelection = (OASingleSelectionBean)tableBean.getTableSelection();
For this singleSelection object I was unable to find any method which will give the value of the view attribute associated with it.
Anybody any suggestions regarding it ?
Thanks in advance,
Anant NImbalkar.

Hi Anant,
here is how you have to do it
1) you need to enable PPR on that Singl selection , by changining the Action type =fireAction.
2) define the envent , EVENT
3) define paramters for that event. This is place that gives you handle to the Attribute of VO.
So you can define paremters such
Name = PARAM1
value =${oa.EqxContactPrivEOVO1.ContactPrivilegeId}
You can define as many paramters as you can for the vo field that u wanted to have.
Now in the procesformRequest() , all you do it handle the event EVENT and get the parameters
if ("EVENT".equals(pageContext.getParameter(EVENT_PARAM)))
String accountid= pageContext.getParameter("PARAM1");
You can refer developer guide for further details.

GetSelectedRowKeys() returns more than one on Single Selection Tree Table

Hi,
I found that this issue occurring after PS3 (I think.)
I have a tree table component, which allows single row selection. There is a listener on a column of the tree table as follows:
public void listenPackageUnit(ValueChangeEvent valueChangeEvent)
Object oldKey = getTreeComponent().getRowKey();
try
* Retrieve index of selected package unit
* NOTE: Subtract 1 to remove no selection value. This only
* needs to be done if attached LOV has No Selection option set.
if (valueChangeEvent.getNewValue() != null)
Row row = null;
String selectedPackageUnit = null;
int packageUnitIndex = (Integer) valueChangeEvent.getNewValue();
packageUnitIndex--;
* Due to the no selection item, we need to prevent search of regular
* iterator if index is < 0. In this case we know the user selected
* the no selection (blank) value.
if (packageUnitIndex >= 0)
* Using index, determine the value of the selected package unit
DCIteratorBinding packageUnitsIterator =
(DCIteratorBinding) PasUiADFUtil.resolveExpression("#{bindings.PackageUnitsIterator}");
Row newRow =
packageUnitsIterator.getRowAtRangeIndex(packageUnitIndex);
selectedPackageUnit = (String) newRow.getAttribute("LookupCode");
RowKeySet selection = this.getTreeComponent().getSelectedRowKeys();
if (selection != null && selection.getSize() > 0)
for (Object facesTreeRowKey: selection)
this.getTreeComponent().setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData =
(JUCtrlHierNodeBinding) this.getTreeComponent().getRowData();
row = rowData.getRow();
setSelectedLabel((String) row.getAttribute("Label"));
setSelectedLabelType((String) row.getAttribute("LabelType"));
row.setAttribute("PackageUnit", selectedPackageUnit);
getTreeComponent().setRowKey(oldKey);
finally
getTreeComponent().setRowKey(oldKey);
The issue is that getSelectedRowKeys() returns more than one when the user selects a child row in the tree table.
It seems to be returning the total number counting from the top parent through the child.
(For example, if the child is the second generation, it returns 2, and if the third generation, it returns 3.)
This is causing the issue that the method tries to update the attribute of the parent row with a value for the child row. (And it fails, because the attribute is updateable only while new.)
I remember getSelectedRowKeys() always returned one, the selected child itself, when I coded this around October, 2010.
Is this a design change after PS3? Why does it return more than one though the tree table is for single selection?
How can I get around this issue?
It would be truly appreciated if we can get any quick help, since we are at final testing phase of our product.
Thank you,
Tomo

Hi Vinod,
I found the solution. Thank you very much for your suggestions. :)
Now my listenSelection (custom listener of the tree table) looks like below:
public void listenSelection(SelectionEvent selectionEvent)
Row currentRow;
PasUiADFUtil.invokeEL("#{bindings.TransactionLabelTopLevelVO1.collectionModel.makeCurrent}",
new Class[] { SelectionEvent.class },
new Object[] { selectionEvent });
Object oldKey = getTreeComponent().getRowKey();
try
if (this.getTreeComponent() != null)
RowKeySet rks = this.getTreeComponent().getSelectedRowKeys();
Iterator keys = rks.iterator();
while (keys.hasNext())
List key = (List) keys.next();
this.getTreeComponent().setRowKey(key);
JUCtrlHierNodeBinding node =
(JUCtrlHierNodeBinding) this.getTreeComponent().getRowData();
if (node != null)
currentRow = node.getRow();
if (currentRow != null)
this.setSelectedRow(currentRow);
setSelectedLabel((String) currentRow.getAttribute("Label"));
setSelectedLabelType((String) currentRow.getAttribute("LabelType"));
String shippedItemFlag =
(String) currentRow.getAttribute("ShippedItemFlagValue");
if (shippedItemFlag != null && shippedItemFlag.equals("1"))
setDisableAdd(true);
else
setDisableAdd(false);
finally
getTreeComponent().setRowKey(oldKey);
/* Refresh Action menu and buttons */
RequestContext.getCurrentInstance().addPartialTarget(this.getActionMenu());
RequestContext.getCurrentInstance().addPartialTarget(this.getToolbar());
And my tree table is like below:
<af:treeTable value="#{bindings.TransactionLabelTopLevelVO1.treeModel}"
var="node" rowSelection="single" id="tt1"
contentDelivery="immediate" fetchSize="25"
emptyText="#{bindings.TransactionLabelTopLevelVO1.viewable ? commonFoundationMsgBundle.NO_DATA_TO_DISPLAY : commonFoundationMsgBundle.ACCESS_DENIED}"
selectionListener="#{pageFlowScope.MaintainTransactionSerialAssociationBean.listenSelection}"
binding="#{pageFlowScope.MaintainTransactionSerialAssociationBean.treeComponent}"
summary="#{maintainAssociationUiBundle.CONTAINER_SERIAL_HIERARCHY}">

The listener is now always getting the currently selected row only.

How to set the first row as selected in single selection of table

when the page renders how do we make the first row as selected for single selection in a table.
Thansk a lot for your help

set the selection Attribute's value to 'Y' for the first row. Thats enough.
eg;
Row row=vo.first();
row.setAttribute("SelectionAttribute", "Y");

Single Selection Problem in table

Dear All,
I am getting problems with single selection in a table. Although I have set the selection model to single, if I select a row int the table and then depress Ctrl/Shift multiple rows are selected.
The code for set single selection is :
ListSelectionModel seleModel = myTable.getSelectionModel();
seleModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
Any idea about this? Is this a bug in JAVA?
Thanks!

Look through your code and see if you've declared your table twice. Your single selection may not being applied where you intended.

Single select option in table view as radio button without design

Hi,
When I use the Content design = "Design2002" or design = "Design2003" then I get a checkbox in table view by giving the single select option. But when I do not use any design for the Content then I get a radio button in the table view.
How do I get a radio button in the table view with Content Design = "Design2002" or design = "Design2003"?

Universal Entity EJB find/select method for single db table

Hi there.
I'm quite new in bea spheres and my question reflects my small knowledge:
Is there any way to perform "universal" sql query on single database table via find/select methods? This means, that I would like to pass whole WHERE clause to these methods, not just some fields values.
What do I mean?
Normally we define find/select method that looks like this one:
SELECT OBJECT(o) FROM Cities AS o WHERE population>=?1 AND state=?2
We call this a method this way:
finder1 (1000000, 'France')
Method returns collection with objects holding data about cities in France with more than 1000000 inhabitans..
But, I want to define method, that could be called this way:
finder1 ("o.population>=1000000 AND o.state='France'")
This method should be able to perform any query on 'Cities' database table.
I tried with defining find method for following query:
SELECT OBJECT(o) FROM Cities AS o WHERE ?1
but it does not work, of course.
Is there possibility to define method that could be called this way?

Selecting data from Multiple Partitions in a single select stmt.

Hi all,
My Database is very large & my tables are partitioned.
My question is:
1) If my data is spread across multiple partitions, is there any way to select data from multiple partitions in a single query?
If we dont mention partition name also it works fine, but perofmance wise it will be very slow. (Using EXPLAIN PLAN)
(Note:I dont want to make use of Union concept, i want to do it in a single select statement)
For ex:
qry1.sql:
select empno from emp_trans partition (P012000)
This above query(qry1.sql) will work fine.
qry2.sql:
select empno from emp_trans partition (P012000,P022000)
The above query(qry2.sql) will return will return the following error:
ORA-00933: SQL command not properly ended
If anybody has any solution for this, pls mail me immediately.
Thanks in advance
bye

All my queries are dynamically generated. All my tables are also indexed partition wise based on date field. My question is, if i want to mention multiple partition names at the time of generating my query(select), then with parformance will be good. I have refered some books, inthat what they say is to use UNION concept, i dont want to use that, instead i want in a single select statement.
Thaks for ur reply

Looking for a best query for multiple IF Else statement in a single select

Hi
I want to run multiple IF Else statements in a single select SQL, each statement is one SQL operating on the same table, what is the best way to write this select SQL query ?

I Apologize, the information i have given might not be enough.
This is my scenario,
I am selecting set of rows from the table for the employee id. After selecting those records,
i need to go through the result list and check the condition 1, if it is met, i will return that employee record.
If that condition 1 is not met, then i need to go through the condition 2. If that is met, i will return that record.
Like wise, i have four conditions.
I am trying to achieve this in a single sql. If i am not clear, please let me know.Not fully clear yet, but the picture is better already. The thing with SQL is that you should stop thinking procedurally. Instead think in data sets.
For example if the task is:
Find all managers that work in sales.
Procedural thinking would work like this:
pseudo code
Loop over all employees that work in sales
   for each row
       check if it is a manager
           if manager
              then return record
           else
              do nothing
           end
end loopThinking in datasets will result in a different logic
pseudo code
select all employees
where department = SALES
and job = MANAGERThis advantage here is that all the "Do nothing" loops are not needed. Those are already eliminated by the database.
So what is needed to help you? Give the full picture. What is your task that you try to solve. From a business perspective.

Hi,
1.Just see this:
SELECT * INTO CORRESPONDING FIELD OF TABLE itab
FROM t1 INNER JOIN t2 ON t1f4 EQ t2f4
INNER JOIN t3 ON t2f5 EQ t3f5 AND
t2f6 EQ t3f6 AND
t2f7 EQ t3f7.
2.But better to use for all entries.It increases the performance.
FOR ALL ENTRIES
Tabular Conditions
The WHERE clause of the SELECT statement has a special variant that allows you to derive conditions from the lines and columns of an internal table:
SELECT ... FOR ALL ENTRIES IN <itab> WHERE <cond> ...
<cond> may be formulated as described above. If you specify a field of the internal table <itab> as an operand in a condition, you address all lines of the internal table. The comparison is then performed for each line of the internal table. For each line, the system selects the lines from the database table that satisfy the condition. The result set of the SELECT statement is the union of the individual selections for each line of the internal table. Duplicate lines are automatically eliminated from the result set. If <itab> is empty, the addition FOR ALL ENTRIES is disregarded, and all entries are read.
The internal table <itab> must have a structured line type, and each field that occurs in the condition <cond> must be compatible with the column of the database with which it is compared. Do not use the operators LIKE, BETWEEN, and IN in comparisons using internal table fields. You may not use the ORDER BY clause in the same SELECT statement.
You can use the option FOR ALL ENTRIES to replace nested select loops by operations on internal tables. This can significantly improve the performance for large sets of selected data.
Example for ALL ENTRIES
DATA: TAB_SPFLI TYPE TABLE OF SPFLI,
TAB_SFLIGHT TYPE SORTED TABLE OF SFLIGHT
WITH UNIQUE KEY TABLE LINE,
WA LIKE LINE OF TAB_SFLIGHT.
SELECT CARRID CONNID
INTO CORRESPONDING FIELDS OF TABLE TAB_SPFLI
FROM SPFLI
WHERE CITYFROM = 'NEW YORK'.
SELECT CARRID CONNID FLDATE
INTO CORRESPONDING FIELDS OF TABLE TAB_SFLIGHT
FROM SFLIGHT
FOR ALL ENTRIES IN TAB_SPFLI
WHERE CARRID = TAB_SPFLI-CARRID AND
CONNID = TAB_SPFLI-CONNID.
LOOP AT TAB_SFLIGHT INTO WA.
AT NEW CONNID.
WRITE: / WA-CARRID, WA-CONNID.
ENDAT.
WRITE: / WA-FLDATE.
ENDLOOP.
INNER JOINS
In a relational database, you normally need to read data simultaneously from more than one database table into an application program. You can read from more than one table in a single SELECT statement, such that the data in the tables all has to meet the same conditions, using the following join expression:
SELECT...
FROM <tab> INNER JOIN <dbtab> AS <alias> ON <cond> <options>
where <dbtab> is a single database table and <tab> is either a table or another join expression. The database tables can be specified statically or dynamically as described above. You may also use aliases. You can enclose each join expression in parentheses. The INNER addition is optional.
A join expression links each line of <tab> with the lines in <dbtab> that meet the condition <cond>. This means that there is always one or more lines from the right-hand table that is linked to each line from the left-hand table by the join. If <dbtab> does not contain any lines that meet the condition <cond>, the line from <tab> is not included in the selection.
The syntax of the <cond> condition is like that of the WHERE clause, although individual comparisons can only be linked using AND. Furthermore, each comparison must contain a column from the right-hand table <dbtab>. It does not matter on which side of the comparison it occurs. For the column names in the comparison, you can use the same names that occur in the SELECT clause, to differentiate columns from different database tables that have the same names.
The comparisons in the condition <cond> can appear in the WHERE clause instead of the ON clause, since both clauses are applied equally to the temporary table containing all of the lines resulting from the join. However, each join must contain at least one comparison in the condition <cond>.
Example for INNER JOINS
REPORT demo_select_inner_join.
DATA: BEGIN OF wa,
carrid TYPE spfli-carrid,
connid TYPE spfli-connid,
fldate TYPE sflight-fldate,
bookid TYPE sbook-bookid,
END OF wa,
itab LIKE SORTED TABLE OF wa
WITH UNIQUE KEY carrid connid fldate bookid.
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab

pconnid = fconnid )
INNER JOIN sbook AS b ON bcarrid = fcarrid AND
bconnid = fconnid AND
bfldate = ffldate )
WHERE p~cityfrom = 'FRANKFURT' AND

fseatsmax > fseatsocc.

MVC: Create a view which populates two (or more) joined tables in a single view table

I am beginner in MVC and I would like to create a view which populates two (or more) joined tables in a single view table as described below.
I have two tables:
1 - Bloggers: - bloggerID (int);
                    - bloggerName (string)
2 - Blogs: - blogID (int);
bloggerID (int);
                - blogTitle (string);
                - blogImage (string)
A blogger can have one or more blogs while one blog must be related to only one blogger.
I would like to have a view table on my webpage as the following:
Blogger Name
Blog Title
Blog Image
Noris Gang
Virus
virus.jpg
Noris Gang
Desktops

Gauthier
Books

I'm using MVC 4 (or at least 3).
Thanks for your help.

Hello,
From your description, it is not very clear that what you mean about the View, if it means the View concept in database as SQL Server, your required view should be as below:
Create view
as
Select Bloggers.bloggerName, Bloggers.blogTitle, Bloggers.blogImage
From Bloggers join Blogs on Bloggers.bloggerID = Blogs. bloggerID
If it means the UI view in MVC concept, I suggest you could ask it on the MVC forum:

How to identify missing records in a single-column table?

How to identify missing records in a single-column table ?
Column consists of numbers in a ordered manner but the some numbers are deleted from the table in random manner and need to identify those rows.

Something like:
WITH t AS (
           SELECT 1 ID FROM DUAL UNION ALL
           SELECT 2 ID FROM DUAL UNION ALL
           SELECT 3 ID FROM DUAL UNION ALL
           SELECT 5 ID FROM DUAL UNION ALL
           SELECT 8 ID FROM DUAL UNION ALL
           SELECT 10 ID FROM DUAL UNION ALL
           SELECT 11 ID FROM DUAL
-- end of on-the-fly data sample
SELECT '[' || (id + 1) || ' - ' || (next_id - 1) || ']' gap
FROM (
         SELECT id,
                 lead(id,1,id + 1) over(order by id) next_id
           FROM t
where id != next_id - 1
GAP
[4 - 4]
[6 - 7]
[9 - 9]
SQL> SY.
P.S. I assume sequence lower and upper limits are always present, otherwise query needs a little adjustment.

LOV single selection list is not working in my JDeveloper 10.1.2.3

Hi!
I'm stumped with this. I'm also new to JDeveloper. I used the sample tutorial from the OTN website entitled "JSPDataBoundLists.jws" to learn how to create drop-down lists in JDeveloper.
My problem is I created a single selection list LOV from DepartmentListView Data Control and pasted it into an EmployeesView Input form. This is so I can just select the Department names to populate the DepartmentID field in Employees table. I setup the data binding in the UI Model of my jsp using the "List Binding Editor". I checked the UIModel file and it looks as follows:
<DCControl
id="DepartmentId2"
SubType="DCListSingleSel"
IterBinding="EmployeesViewIterator"
DTClass="oracle.adf.dt.objects.JUDTCtrlListLOV"
ApplyValidation="false"
isDynamic="false"
ListOperMode="0"
ListIter="DepartmentsListViewIterator" >
<AttrNames>
<Item Value="DepartmentId" />
</AttrNames>
<ListAttrNames>
<Item Value="DepartmentId" />
</ListAttrNames>
<ListDisplayAttrNames>
<Item Value="DepartmentName" />
</ListDisplayAttrNames>
</DCControl>
I run the jsp, selected a value from the drop-down list, do a submit and do a commit, but the DepartmentId from the DepartmentsListView was not stored in Employees. What is wierd here is that there is an exact same single selection list defined a row above mine which is working fine. How come that one is working and mine is not?

Eureka! I finally found the answer to my own question!
This simple problem of adding a drop-down list into a jsp page cost me 3 whole days (around 24 full working hours) to find the answer. Normally it only takes me a few minutes with the other web app languages I've learned. And I just stumbled into the answer just a few minutes ago (maybe all thanks should be given to God whom let me stumble into the answer since me and my wife have been praying for several weeks now ever since I started trying to learn Oracle JDeveloper. It is really very very difficult and time consuming to learn compared to other web app languages and tools).
Anyway, the reason why my LOV does not work in my jsps using JDeveloper 10.1.2.3 is because JDeveloper 10.1.2.3 seems to allow only one input-form-element for the same field of the input table!
For example, what happened to me was I had an input form created for the Employees table in the HR schema. I did this simply by drag-and-drop from the "Data Control Palette". This feature I like very much with JDeveloper. It is really easy and works instantly. And then, I drag-and-drop the departmentname field from the Departments table as a "single selection list" into the jsp and setup its bindings. So when I run the jsp, viola! The drop-down list does not populate the DepartmentId field of the Employees table. IT DOES NOT WORK! I've tried reinstalling both JDev and Oracle db and JDKs to no avail! I tried posting in this forum to no avail! I tried experimenting with newly created jsps to no avail! Then suddenly after repeatedly experimenting on this on different tutorials, guides and my own web app, it works! Why did it work? It was because I tried to add an LOV-single-selection-list on another sample tutorial with a READ-ONLY FORM on the jsp! Thus only the LOV is the input-form-element in the jsp for the table's field.
So why can't you find such a simple and basic fact anywhere in the web, the tutorials, guides or the forum? I do not know. Maybe only I am using such an old version of JDev? But what about the users who used it when it just got out a couple of years ago? Didn't they have the same problem? Anyway, it seems like the answer to a lot of my simple basic questions about JDeveloper is not documented, or is buried very deep beneath all the other words of all these documents. Hopefully JDeveloper's documentations would get a lot easier to use very very soon!
