JComboBox: arrowkey-selection : keep value of the display area

Hello!
I need to have a combobox where the user can iterate through its items using the arrowkeys without changing the value on the displayField. This should only change when the user presses Return.
Does anyone knows how should I proceed in order to have this behaviour?
Thank you,
Pedro

Hi,
I know a solution.
You use only a JTextField , set in editable false and implements a MouseListener. So when the user click on the JTextFied a ComboBoxPopup opens( where you want - normaly under the textfield).
these code you need :
// for the DefaultComboBoxPopup
import javax.swing.plaf.basic.BasicComboPopup;
// construct an instance using your old JComboBox
BasicComboPopup bcp = new BasicComboPopup(yourComboBox);
/** Later in the code you can use the ComboPopup like a normal JPopupMenu to show the popup and hide the popup and set the location of it*/
bcp.setLocation(x, y);
bcp.setVisible(true);Then you must only install a ListSelectionListener or a Keyboard and a MouseListener on the JComboBox to react on user-input, to store the selected value in the JTextField.

How to select multiple values from the parameters in BI Publisher report

How to select multiple values from the parameter drop down in BI Publisher, and how to handle this mulitple values from the report sql...

Hi kishore,
I have used all the steps as you mentioned in your previous reply....including checking Mulitple Selection Check Box..
Iam able to get the results when I am selecting one value..
and also I am able to handle multiple values the in the query by using IN :Parameter, but seems when we select more than one value from the parameter drop down i think the Bi Publisher is sending the values in concatenated form something ilke
ex: "'ACCOUNT','HR','SALES'" ,and when trying to display the parameters values in the output, its throwing the error as 'missing right paranthesis' ....on the whole do you have any solution which would handle
1.Single selection.
2.Multiple selection.
3.'ALL' Values.
4.Separating the concatenated string into individual strings and dispaly them on the output of the report..etc..in case of Mulitple selection.
Ex:
Concatenated String from BI Publisher:"'ACCOUNT','HR','SALES'"
Expected Output on the report:ACCOUNT,HR,SALES
reply to this would be much appreciated....
thanks,
manoj

How to select multiple values from the Parameters in the concurrent program

How to select multiple values from the Parameters defined in the concurrent program...and i believe multiple selection is not a direct feature of EBS, but is there any workaround solution to acheive mulitple selection?

I think there's no way to do that using standard feature.
Some workaround I use :
1. If the number of selections are fixed, you could use multiple parameters for the same valueset. For example :
Selection1 : <choose first selection>
Selection2: <choose 2nd selection>
..etc.
If you don't use it then leave it empty.
2. Use text varchar valueset and enter it manually and separate by comma (or other value) , eg : selection1,selection2,selection3....etc.

How to select all single values in the header area

Dear Experts
I got a request that the user wants to select a single value or all single values in the header area. E.g. if the values from characteristic master data are A, B, C and D, the selection can be one of these values or all of them. With the standard BPS configuration, due to the unique combination in the header area, selection of 'All' single values is not possible. Is there a way to select all single values in the header area?
Thanks, Jessica

Hi Jessica,
Here is a solution where you need not to change your planning layout or to create a new variable or any exit function.
Step 1 - Maintain master data value 'ALL' in the required characteristic.
Step 2 - Create a copy function to copy all the required data records to 'ALL'. you can use standard copy function where you have to include only this characteristic in the fields to be change.
Copy -
From = all values (A,B,C,D etc)
To = "ALL".
Step 3 - Call this function on layout opening. you can include it in the planning folder and change the function attribute to call it on layout opening.
Step 4 - Create a standard Delete function. you have to call this function on save operation. In this function, you have to delete all data records present in the buffer where required char contains 'ALL' value.
This approach can impact the performance of the planning application. It depends on the number of data records you are dealing with. Standard Copy and Delete functions are pretty fast in nature.
I hope it will help you. please let me know if you need more inputs.

Tarun

Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

Thanks, Dave A.

A Java AWT, X11 problem posted in the weblogic ejb newsgroup. I haven't been in here for long, but
that has to be a first.
If you have the DISPLAY env variable set to :0.0, you have to be at the console on a Solaris box
running the XServer. 'xdm' I think is the code that has to be running. Also, I think the format is
<hostname:0.0> or better <hostname:0> unless you are on a multi-headed workstation. Something like:
export DISPLAY=hostname:0
where hostname is the name of the host running an XServer and the .xhosts file allows access to the
XServer from the display client.
Apparently, you are not at the console?
Anyway, I don't think there is a newsgroup here that I could even recommend to cross-post this to as
it is not a WebLogic question. I think I would try the Discussion Forums at http://java.sun.com.

i got the tip of passing -Djava.awt.headless=true to vm to disable system graphic calls but after restart weblogic i still get the same error
i am wondering if this case has something to do with jdk 1.3.1, and perhaps newer versions of jdk can take the parameter and operate correctly
is that right?

is headless option supported in jdk1.3.1?No,
It was added in JDK 1.4:

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

When trying to import photos with iPhoto from photoshop.. won't let me keeps saying that the photos are already in the iPhoto library but they are not... need to fix this

When trying to import photos with iPhoto from photoshop... won't let me keeps saying that the photos are already in the iPhoto library but they are not

If you are using Photoshop from within iPhoto the following may help with the workflow. However, we do need to know the answers to the questions posed by Terence and Larry to be able to help you.
Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.
1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.
2 - double click on the thumbnail in iPhoto to open it in Photoshop. When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done.
3 - however, if you get the navigation window
that indicates that PS wants to save it as a PS formatted file. You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.
This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..
With Photoshop Elements the Saving File preferences should be configured as shown:
I also suggest the Maximize PSD File Compatabilty be set to Always. In PSE’s General preference pane set the Color Picker to Apple as shown:
Screenshots are from PSE 10
Note 1: to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.
Note 2: editing a RAW file with either PSE or PS creates a new file which must be saved outside of iPhoto, i.e. the Desktop, and imported as a new photo into the iPhoto Library.

Passing values to the TEXT AREA in .HTML page.

Hi,
I have data in internal table and in context node in custom CRM component.
I want to display this data in the textarea field. Is it possible to display this data in the text area? Should we use JAVASCRIPT for this one?
Can anyone please give me the smaple code for passing the values to the text area?
Please help me.
Regards,

Hi Pushpa,
You can set the internal table values to the text area field using SET_PROPERTY method .
Check for the context node in which that text field is there ,then get that context nodes current entity .Next set required values to that text area field.

Why can't I select "get info" from the file area so I can change the setting to "open in 32-bit mode" ?

It may be because of your settings. You can modify that setting in System Preferences > Trackpad. Another way of making right-click is to click the app icon while holding the Control key

Retriving data from database on selecting particular value in the combo box

Hi,
On selecting the particular value from the combo box, the corresponding value of the other segement fields should be retrived from databse and displayed in the text box

Babel,
If you don't have a query bdoc and the business query that joins both 2 tables already, then please crate one.
After that, write this code on the change of the combobox.
You would have to change the names below for the Query, properties, anchor, parameters, controls.
===================================
Private Sub ctrlBankNameCombo_onValueChanged2(ByRef boundAttributeChanged As Boolean)
On Error Resume Next
Dim objBankQuery As BusinessQuery
Dim ObjBankCol As BusinessCollection
Dim strID As String
If Not boundAttributeChanged Then Exit Sub
strID = ""
strID = myanchor.bo.getAttribute("BankNameComboProperty") ' Bank ID
If strID <> "" Then
    Set objBankQuery = gServices.factory.newBusinessQuery("MyNewQuery")
    objBankQuery.Mandt = "000"
    objBankQuery.BANKID = strID
    Set ObjBankCol = objBankQuery.query
       If Not ObjBankCol Is Nothing Then
           ctrlBankAddress.Value = ObjBankCol.getAttribute(1, "BankAddress")
           ctrlBankPhone.Value = ObjBankCol.getAttribute(1, "BankPhone")
       End If
End If

Select multiple values from the parameters in BI Publisher report Error

please help me!
Thanks all!

See my response in the thread Re: Multi selecting drop down in BI publisher 11g report
The LOV is a Java array and your function needs to accept that array. To do this the data data type has to be a VARRAY Type.
