Folder Chooser reference (which uses a tree for selection)

is there a recommendation for a folder chooser which uses a tree for selection? all i've found so far are either:
* 3rd party folder choosers
* the file open dialog box of java where you use setFileSelectionMode( JFileChooser.DIRECTORIES_ONLY);
i can't believe there is currently no folder chooser which uses a tree for selection in standard java. so probably i didn't find it. before i write my own, i thought i'd ask.
thanks for the help!

No, it doesn't exist in the standard Java API. What's wrong with third party solutions, especially when some of them are open source? Google found quite a few.

Index used or not for selecting data from ODS in a start routine

Dear friends,
In the start routine of the update rules to a cube, I am reading some data of an ODS in to an internal table .
The ODS is indexed. But, I am not sure if the index is at all used in the Select statement (that gets the data from ODS to the internal table in the start routine) while loading data to the cube.
Any help is highly appreciated.
regards,
atlaj

Hi Atlaj
You can findout this is display execution plan for SQL statement in DB02.
Goto DB02. and under diagnostic, you find explain. Select that and enter your query. Make sure that everything here is in capital format. Below is a sample query which I have entered.
SELECT "CRM_SALORG" "SALESORG" FROM "/BI0/QORGUNIT"
WHERE "SALESORG" = ? AND "OBJVERS" = ? AND "DATETO" >= ?
AND "DATEFROM" <= ?
The select parameters should be inside qoutes and in caps and even the from table. Once you enter your query in this format, click on explain. It will show the index scan if the index is present. the output for my query will be something like
0 SELECT STATEMENT ( Estimated Costs = 1,348E+01 [timerons] )
        1 (COOR) RETURN
            2 (    0) TQ
                3 (    0) FETCH /BI0/QORGUNIT
                    4 (    0) IXSCAN /BI0/QORGUNIT~Z1
Where my last statement (line 4) is showing index scan and the name of index read is Z1.
Hope this helps.
Please let me know if you have any problems entering the query in the specified format and u get any error.

Using NAST info for selection screen design

Hi
I am doing customization for RFQ printing ( TCODE ME9A)
I want to know can I get the same selection screen as of ME9A using NAST info for my z driver program.
Which function module can be used?
Kindly provide sample code

Hi Piyush,
Add the below code in your program.

About to use my tree for firewood

I was wondering if someone could maybe clue me into a problem that I am having with my DefaultMutableTree. See, I call a recursive method to get the file system of the computer, which is what is added to the tree. So the user is looking at a tree structure of the file system of their computer. My problem is that when I compile and run my program the tree shows up fine, with no hitches. I have given my code to other friends, and for some of them it does not show up, and throws a null pointer exception at the internal interface of this recursive method. I was wondering what might be causing this? My friends that have problems with the code are running either WIN XP, or Mac OS 10.1.4. Here is the code for the initialization of the tree (This will look ugly on the post, so I would hope that you would take the time to copy and paste this into your editor :D)

I have given my code to other friends, and for some of them it does not show up, and throws a null pointer exception at the internal interface of this recursive method. I was wondering what might be causing this? My friends that have problems with the code are running either WIN XP, or Mac OS 10.1.4. Here is the code for the initialization of the tree (This will look ugly on the post, so I would hope that you would take the time to copy and paste this into your editor :D)

I ran this on XP and got the null pointer exception...
it's likely that it's running into a file or directory that it can't list (in my case it was a mount on a different directory ntfs is kinda cool)... SO... to handle that problem I just put the whole method in a try / catch block
it was just the method unfold ... the fix returns a blank treenode... it should probably return null and the caller should see that as a sign to not add it to the tree...
     private DefaultMutableTreeNode unfold(File path) {
          DefaultMutableTreeNode node = new DefaultMutableTreeNode("");

Use of SetFormattingSheet for selection of EPMFormattingSheet in BPC 10.0

I am trying to select a Formatting sheet to be applied based on the category selection. Can someone help me with the VBA code for the same? The code I have written is just refreshing the sheet and not applying the formating sheet. Is there any other option by which we can change the formatting based on selection in the Page Axis?
Private Sub CommandButton1_Click()
Dim category As String
category = Range("D3").Value
Dim client1 As New EPMAddInAutomation
If category = "Actual" Then
client1.SetFormattingSheet Worksheets("Sheet1"), "Default Report", "EPMFormattingSheet"
End If
If category = "Budget" Then
client1.SetFormattingSheet Worksheets("Sheet1"), "Default Report", "EPMFormattingSheet (2)"
End If
Dim client As New EPMAddInAutomation
client.RefreshActiveSheet
End Sub

How to add folder from KM content to Portal Favorites for selected users

Hi all,
I have cretaed a folder in KM content (In documents) for uploading implementation related ddocuments.
how to add this folder in "Portal Favorites" of selected users only.
Please guide.
Thanks in advance.

Hi,
well one way could be the following.
Go into KM-Content --> Repository "userhome" --> select the user you want --> navigate into his folder Favorites --> create a new internal link in this folder to the folder you want
In the favorites of the user there is now a link to the desired folder and after clicking a new window will be opened. You can copy this internal link to the favorites folder of the other users you want.
Regards
Alex

APO DP - use of tables for selections and notes

I am using APO DP V5.
I note that tables for holding selections and notes are planning area specific and have tables names such as /1APO/S1nnnnnnnn and /1APO/F1nnnnnnnn respectively.
My questions:
1. What is the logic for the naming of these tables
2. For a given planning area, are the tables names the same as one moves from Development to QA to Production environments
Thanks,
Bob Austin

Bob
I think the answer for the notes part of this question is here. The logic for the selections should be the same
Re: Updating of Notes for cells in APO DP
The table names might not be the same in QA since they are created independently and dynamically. But one way to check is to try it out

Using execute immediate for select

Hi all,
i am writing a procedure as follows:
create or replace procedure ( run_yr_mo in number) as
v_count number := 0;
begin
execute immediate 'select count(*)
from all_tables
where owner = ''MGR''
and table_name = ''FC_PR_'''||run_yr_mo||''
into v_count;
dbms_output.put_line(v_count);
end;
this is returning me an error at the execute immediate.
run_yr_mo = 200912
Can someone help me out with this.
Thanks

Just to show it working:
SQL> create or replace procedure myproc ( run_yr_mo in number) as

Bug when using a Map for SelectItems?

Hi there,
I think I found a pretty bad bug.... I don't think this behaviour is intended:
I create a selectOneListbox which uses a map for storing the selectItems. The property holding the value is type compatible with the value in the map. When the component is shown, the wrong item is selected (ie NOT The one that is returned by the value property). If I use SelectItem[] for the selectItems, it works. Here is some sample code:
The methods in the bean (managed bean with the name helloBean). The value property always returns 12 .....
public Map getItems(){
    Map map = new HashMap();
    map.put("Hello_11", new Integer(11));
    map.put("Hello_12", new Integer(12));
    map.put("Hello_13", new Integer(13));
    map.put("Hello_14", new Integer(14));
    return map;
public SelectItem[] getItems2(){
    SelectItem[] items = {
        new SelectItem(new Integer(11), "Hello_11"),
        new SelectItem(new Integer(12), "Hello_12"),
        new SelectItem(new Integer(13), "Hello_13"),
        new SelectItem(new Integer(14), "Hello_14"),
    return items;
public Integer getValue(){
    return new Integer(12);
}..... here is how the selectOneListboxes are initialized ......
<h:form id="helloForm">
        <h:selectOneListbox size="1" value="#{helloBean.value}">
          <f:selectItems value="#{helloBean.items}"/>
        </h:selectOneListbox>
        <h:selectOneListbox size="1" value="#{helloBean.value}">
          <f:selectItems value="#{helloBean.items2}"/>
        </h:selectOneListbox>
</h:form>.... so both boxes refer to the same value property but their selectItems are taken from a map and a SelectItem[] array respectively. I would expect to see in both boxes the text "Hello_12", BUT:
<select name="welcomeForm:_id0" size="1">
     <option value="14">Hello_14</option>
     <option value="12">Hello_12</option>
     <option value="13">Hello_13</option>
     <option value="11">Hello_11</option>
</select>
<select name="welcomeForm:_id2" size="1">
     <option value="11">Hello_11</option>
     <option value="12" selected="selected">Hello_12</option>
     <option value="13">Hello_13</option>
     <option value="14">Hello_14</option>
</select>as you can see, only for the array the correct value is initially selected.
Can anyone confirm this is a bug - or - what i would prefer tell me how to get around this?
Thanks a lot!

If getValue returns "12" (a String value), the situation is reversed.
See the page 9-31 of the specification. It says:
4. A java.util.Map where the keys are
converted to Strings and used as labels, and
the corresponding values are converted to
Strings and used as values for newly
created javax.faces.model.SelectItem
instances. The instances are created in the
order of the iterator over the keys provided
by the Map.

Using High-Level API, need to use KeyRelease just for Lists

I'm coding a MIDlet with High-Level API, but I found that is really annoying to press down 30 times in a long List to reach the item you want to select. So I thought "what about pressing right/left and make it working like pressing down/up like 10 times"?
Something like this:
Canvas canvas = new Canvas() {
         public void paint(Graphics g) { }
         protected void keyPressed(int keyCode) {
            switch(keyCode) {
                case -3:mylist.setSelectedIndex(mylist.getSelectedIndex()-10,true);break;
                case -4:mylist.setSelectedIndex(mylist.getSelectedIndex()+10,true);
      }; // end of anonymous class*/But I have no idea about how to implement this =(

first of all, is there any particular reason you want to stick to the high-level API?
Well, I have already nearly 700 lines of code. I don't want to start from 0 :P
I think the best way to implement this would be to use customItems so you can control the view of the list.
I think that requires MIDP2.0 I'm trying to make it work in MIDP 1.0
The best you could do with high level UI is add navigation Commands to the List.
I have already 2 Commands per List. Not all phones have a button in the center of "cursors", so I use right button for select and left for back/exit.
Thanks for replies anyway

Xsl:sort attribute value templates for select and order

I've tried the xdk_java_9_0_1_0_0.tar.gz update today and for that the reported bugs are still there : one urgent (quite a stopper for us) is this one
<xsl:template match="/resultlist">
<xsl:variable name="sortorder">descending</xsl:variable>
<xsl:variable name="sortfield">name</xsl:variable>
<xsl:for-each select="result">
<xsl:sort select="./{$sortfield}" order="{$sortorder}"/>
<xsl:value-of select="./index"/>,<xsl:value-of select="./name"/>
</xsl:for-each>
</xsl:template>
still it does not replace {$sortfield} and {$sortorder}.

This is known bug 1798018 in the Oracle XSLT processor.
The only workaround I can think of is to use <xsl:choose> to optionally use different <xsl:for-each> blocks, one with order="ascending" and one with order="descending" as literal values.

WHEN-TREE-NODE-SELECTED Action required..!

Hello all,
i am using a tree for the first time, i want to reflect the value of the node's id and desc in it's database item where they r inserted.
The problem is the desc is not displayed NOT.
But the node id is working just fine..Why ?
Can anyone help me pls..?
i am using the following code:
WHEN-TREE-NODE-SELECTED Trigger:
:EQUIPMENT_TYPE_D := :SYSTEM.TRIGGER_NODE;
--The above returns the item_id of the node.
BEGIN
       SELECT EQUIPMENT_TYPE
       INTO :EQUIPMENT_TYPE
       FROM INSP_EQUIPMENT_TYPE
       WHERE EQUIPMENT_TYPE_D = :EQUIPMENT_TYPE_D ;
Exception
When No_Data_Found THEN NULL;
When Others THEN
                                 Message ('OTHERS' || SQLCODE || ' And ' || SQLERRM);
                                 Message ('OTHERS' || SQLCODE || ' And ' || SQLERRM);
END;Regards,
Abdetu..

The WHEN-TREE-NODE-SELECTED trigger fires twice, it fires when selecting the node and when deselcting the node.
First make sure that you SQL works in SQL*Plus, Handle your EXCEPTION correctly, remove the NULL from your exception and put a message, maybe your SQL is not returning any rows.
add the below if condition in your trigger. This will make your code to be executed only when you select the node and not when you deselect it.
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
...    --Your execution code
END IF; If your item name is the node's label itself you can easily do this:
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
:your_block.your_item := FTREE.GET_TREE_NODE_PROPERTY(HTREE$, :SYSTEM.TRIGGER_NODE, FTREE.NODE_LABEL);
END IF; Tony
