More than One root in Tree Table

Hi all
I am Using Jdev version of 10.1.3 . I am using tree table component .
I am not able to display more than one root at the same time. It usually displays one root and children underneath it if there are multiple roots it has navigation.
But i require to display more than one root at the same time without any navigation. If it is not possible in jdev 10.1.3 how can i acheive the result , i am bound to use jdev 10.1.3 and i need to have a table which has parent and child and all the parents to be displayed at same time, Should i try with any custom renderer.
PleaseAny light on this would be helpful.
Thanks
Pavan

i can select them from different parents that depends on what i want to select Like:
Admin-Sam
-Dinda
Users-David
-Marylinn
-Sandra
for ex: i wana choose Sam , Sandra & David to view thier times and OT on selecting them

RegionRenderer encodeAll The region component with id: pt1:r1 has detected a page fragment with multiple root components. Fragments with more than one root component may not display correctly in a region and may have a negative impact on performance.

Hi,
I am using JDEV 11.1.2.1.0
I am getting the following error :-
<RegionRenderer> <encodeAll> The region component with id: pt1:r1 has detected a page fragment with multiple root components. Fragments with more than one root component may not display correctly in a region and may have a negative impact on performance. It is recommended that you restructure the page fragment to have a single root component.
Piece of code is for region is:-
   <f:facet name="second">
                                            <af:panelStretchLayout id="pa1"
                                                                   binding="#{backingBeanScope.Assign.pa1}">
                                                <f:facet name="center">

                                                </f:facet>
                                            </af:panelStretchLayout>
                                        </f:facet>
How do I resolve it ?
Thanks,

Hi,
I see at least 3 errors
1. <RegionRenderer> <encodeAll> The region component with id: pt1:r1 has detected a page fragment with multiple root components.
the page fragment should only have a single component under the jsp:root tag. If you see more than one, wrap them in e.g. an af:panelGroupLayout or af:group component
2. SAPFunction.jspx/.xml" has an invalid character ".".
check the document (you can open it in JDeveloper if the customization was a seeded one. Seems that editing this file smething has gone bad
3. The expression "#{bindings..regionModel}" (that was specified for the RegionModel "value" attribute of the region component with id "pePanel") evaluated to null.
"pageeditorpanel" does seem to be missing in the PageDef file of the page holding the region

Fetching more than one row from a table after selecting one value from the dropdown

Hi Experts,
How can we fetch more than one row from a table after selecting one value from the dropdown.
The scenario is that I have some entries in the dropdown like below
A               B               C
11256          VID          911256
11256          VID          811256
11256          SONY      11256
The 'B' values are there in the dropdown. I have removed the duplicate entries from the dropdown so now the dropdownlist has only two values.for eg- 'VID' and'SONY'. So now, after selecting 'VID' from the dropdown I should get all the 'C' values. After this the "C' values are to be passed to other methods to fetch some data from other tables.
Request your help on this.
Thanks,
Preeetam Narkhede.

Hi Preetam!
I hope I understand your request proberly, since this is more about Java and less about WebDynpro, but if I'm wrong, just follow up on this.
Supposed you have some collection of your original table data stored in variable "origin". Populate a Hashtable using the values from column "B" (let's assume it's Strings) as keys and an ArrayList of whatever "C" is (let's assume String instances, too) as value (there's a lot of ways to iterate over whatever your datasource is, and since we do not know what your datasource is, maybe you'll have to follow another approach to get b and c vaues,but the principle should remain the same):
// Declare a private variable for your Data at the appropriate place in your code
private Hashtable temp = new Hashtable<String, ArrayList<String>>();
// Then, in the method you use to retrieve backend data and populate the dropdown,
// populate the Hashtable, too
Iterator<TableData> a = origin.iterator();
while (a.hasNext()) {
     TableData current = a.next();
     String b = current.getB();
     String c = current.getC();
     ArrayList<String> values = this.temp.get(b);
     if (values == null) {
          values = new ArrayList<String>();
     values.add(c);
     this.temp.put(b, values);
So after this, you'll have a Hashtable with the B values als keys and collections of C values of this particular B as value:
VID --> (911256, 811256)
SONY --> (11256)
Use
temp.keySet()
to populate your dropdown.
After the user selects an entry from the dropdown (let's say stored in variable selectedB), you will be able to retrieve the collection of c's from your Hashtable
// In the metod you handle the selection event with, get the c value collection
//and use it to select from your other table
ArrayList<String> selectedCs = this.temp.get(selectedB);
// now iterate over the selectedCs items and use each of these
//to continue retrieving whatever data you need...
for (String oneC : selectedCs) {
     // Select Data from backend using oneC in the where-Clause or whatever...
Hope that helps

How to bring the more than one rows from the table into the script

Hi
I have to bring more than one rows from the table into the Main windows of the script. so plz help me out.
Thanks in Advance
Ananya

Hi Ananya,
   Bring more than one row into main window of script.
   For this you need to do some changes for data which you pass to main window.At a time you need to pass more than one row,so for this you need to define one structure.See below code.
Types:begin of ty_rows,
     include structure (your row_structure),
     include structure (your row_sturcture),
Types:end of ty_rows.
for example....
If i need to pass 2 vendor details at a time to main window then the structure should be like this.
Types:begin of ty_rows,
       vendor1 like lfa1-lifnr,
       vendor1_name like lfa1-name1,
       vendor2 like lfa1-lifnr,
       vendor2_name like lfa1-name1,
      end of ty_rows.
Data:i_main type standard table of ty_rows,
     wa_main type ty_rows.
Based on condition you can pass more than one rows of your actual internal table data to i_main internal table.
Then you can pass i_main internal table to your main window.
    I think this will help you.

You can achieve what you want using PL/SQL. Can you post ur code?

More than one signal to the table

hi,
can i input more than one signal that come from" wave chart " into build table block in the same time
if yes >>>how ????
" Science is came....not come "

skype : t_alhowaiti

The Table control accepts a 2D array as an input. If you use a Waveform Graph (not chart), it is pretty easy. You can just build the two arrays into a 2D array (using Build Array) and pass it to the display. However, since a chart updates with each iteration, you cannot easily build it into a 2D array. If your graph is inside a loop, you could pass the data outside of the loop while building an array through auto-indexing.

More than one root table ,how to design cache group ?

hi,
each cache group have onle one root table , many child table ,if my relational model is :
A(id number,name ....,primary key id)
B(id number,.....,primary key id)
A_B_rel (aid number,bid number,foreign key aid referenc a (id),
foreign key bid referenc b(id))
my select statement is "select ... from a,b,a_b_rel where ...."，
i want to cache these three table , how should i create cache group ?
my design is three awt , Cache group A for A , Cache Group b for b, Cache group ab to a_b_rel ?
are there other better solution ?

As you have discovered, you cannot put all three of these tables into one cache group. For READONLY cache groups the solution is simple, put two of the tables (say A and A_B) in one cache group and the other table (B) in a different cache group and make sure that both use the same AUTOREFRESH interval.
For your case, using AWT cache groups, the situation is a bit mnore complicated. You must cache the tables as two different cache groups as mentioned above, but you cannot define a foreign key relationship in TimesTen between tables in different cache groups. Hence you will need to add logic to your application to check and enforce the 'missing' foreignb key relationship (B + A_B in this example) to ensure that you do not inadvertently insert data that would violate the FK relationship defined in Oracle. Otherwise you could insert invalid data in TimesTen and this would then fail to propagate to Oracle.

Search Help on Table Control - Fill more than one field in the table?

Hey everyone,
I have built a screen with a Table Control on it... the fields of the table control are linked to an internal table... The internal table has the line type of a structure I've defined in the data dictionary. Within that structure in the data dictionary, I've linked some fields to search helps (For example, a MATNR and CUSTOMER search help)... I've defined in the structure definition which fields from the search help are to be returned to which fields in the structure.
The problem is, even though I have the search help set to export both the customer number and location when using the search help on the customer field, it still does not fill the location field within the table. Is this a limitation of using search helps within table controls?
I'm also finding that by defining the search help through the structure, instead of directly within the screen, the search help round button does not show up on the field, yet I can still press F4 to bring up the search help. Is there a reason why it's not showing the search help clickable button even though it works fine using F4?
For doing search helps in Table Controls, is it better to just build the search help, attach it directly to the field in the table, and then after the user picks the single field, use the PAI to run a select and fill the rest of the fields required?
Thanks,
Dallas

Hi Dallas,
(1)
What i understood is that you added a search help by defining it in the internal table type for a field customer number..in the search help you have 2 fields customer number and location...user press the search help ..then you need to fill 2 different fields or 1 field?
if you need to fill the customer location or location (only one) then you need to set the "import" in the search help for whichever is required.....
if you need to fill 2 or more different fields..then you can use the technique you have mentioned last , to do a select in PAI and fill the fields....but this you can use if the combination for the fields is unique...eg: u have customer number and location..if customer X can be mapped to location X and location Y..when a select statement is done there are 2 options..so in such cases it is better to leave the option to the user otherwise if there is a clear mapping like customer X can be mapped only to location X then you can use the select..
(2)
usually when you define it as a type in the internal table the icon doesn't show up..but you can do alternative like mentioned..go to the table,find the search help for the required field if present or create a new one if required and place the search help mentioned in the screen itself..so as to see the icon...sometimes users are adamant that they need the search help icon to be seen..so it depends on if your user
(3)
as in the example of customer number and location mentioned we can provide them different search helps and do the needful processing in PAI to fill the fields
Table controls may be used for different purposes and requirements....even a checkbox,push button can be placed as a field in table control and used,but yes most of the time requirements are like what is mentioned in your case...

How do I add more than one column to a table using SQL?

Hi
I need to add 3 columns to a table using SQL
the syntax
"ALTER TABLE TEST ADD COLUMN newcol1 float";
works fine - for adding one coumn only.
For multiple columns I tried various permutations along the lines of
"ALTER TABLE TEST ADD (COLUMN newcol01 float, COLUMN new2 float,COLUMN new3 float)";
"ALTER TABLE TIPSTEST ADD COLUMN new1 float"
"ALTER TABLE TIPSTEST ADD COLUMN new2 float"
"ALTER TABLE TIPSTEST ADD COLUMN new3 float"
etc., but this doesn't work.
From a web search it sounds like SQL can only add one column at a time.
I have a workaround : create intermediate temporary tables , copying data and adding
one column at each stage. It seems a fairly awkward way of programming though.
Am I missing something simple : is there a way to add multiple columns in one go?
Thanks

OK : solved an underlying problem with this one myself
for the code
String createString;
createString = "select COFFEES.* INTO NEWCOFFEES FROM COFFEES"; // example
          Statement stmt;
          try {
               stmt = a_Globals.database1Connection.createStatement();
                      stmt.executeUpdate(createString);
               stmt.close();
               a_Globals.database1Connection.close();
          } catch(SQLException ex) {
               System.err.println("SQLException: " + ex.getMessage());
          }                    commenting out the line:
a_Globals.database1Connection.close();
Allowed the subsequent SQL statement(s) to work OK. Looks like this was the cause of several
difficulties, preventing me doing several SQL instructions in turn.
Thanks for the responses.

One Table more than one Relationship to same Table

Hello,
I have the following scenario.
One Table called Hotel and one Table Called Competitor. Each hotel can have several competitors. So i structured the tables in my Azure SQL database like this:
Hotel:
HotelID (int, Primary Key)
Name (String)
etc.
Competitor Table:
ComeptitorID (int identity Primary Key)
HotelID int
CompetitorHotelID int
When i import the tables in my LS Project i get some issues, like the autocomplete box are not filled up.
Is there a problem if a table has two references to the same table.
Thank you so much for amy help

Hi, this setup works in LightSwitch built in the intrinsic data source.
Hotel <Zero_or_1-to-Many> Competitor <Many-to-Zero_or_1> Hotel
So a hotel can have many competitors and a competitor can compete with many hotels.
Is it possible for you to switch to this?
Cheers

JTree with more than one root node

how?

Still problem left...
if setRootVisible(false) is called then it suppresses the display of root but it suppresses the handle icons too.
Does anyone knows how to display proper tree just without root ?

Fragments with more than one root component may not display correctly ...

Using JDev 11.1.1.3; have a page fragment that contains a layout component for the content, but also an af:popup definition as child to the root tag of the fragment. I get the above design-time warning; wondering whether this is customarily ignored when the secondary components are popups, or whether there is a better way of defining the popup which needs to package with a fragment ?
Thanks,

I get it in the structure pane along with the other Warnings (eg: Reference selectedRow not found).
<jsp:root ...>
<c:set ...>
<af:panelStretchLayout ...>
<af:popup ...>
</jsp:root>
... would put 1 warning in the Structure pane alerting developer to the fact that the popup isn't expected.
Thanks for the assistance.

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.
