Custom DataGrid problems with Comboboxes

I am using a custom datagrid with comboboxes and
colorpickers. I found this code on the web and adapted it to work
with my code. The only problem is that if you pull down a combobox
and then click somewhere outside without selecting anything, it
seems to erase the data in the dataprovider arraycollection and so
'value' in the set data method becomes null.

This is not a bug if I understand you properly. I believe most people would wish anything which is obtained via the tv to be backed up, which is why the content is transferred. If you want it to remain available on the tv you will need to sync it back to it.

this is the code
cb_list.addEventListener(
SliderEvent.CHANGE,changehandler);
function changehandler(e:Event):void {
    var sort1:String=cb_list.value;
    var id:String = myXML.tip.(title == sort1)[email protected]();
     //trace(id)
    var slectedtip = myXML.tip.(title == sort1).fulltip.text();
    tit_label.text=myXML.tip.(@ID == id).title .text();

Problem with ComboBox / Matrix

Hi all,
I have this problem... when I try to populate a column with comboxbox ...
Code:
        Set co = lmatrix.Columns.Add("orgDist", it_COMBO_BOX)
            co.TitleObject.Caption = "Dist"
            co.Editable = True
            co.Visible = True
            co.DataBind.SetBound True, "@DIST", "Code"
        Set DBSource = lfrm.DataSources.DBDataSources.Item("@DIST")
            DBSource.Query
            For x = 0 To DBSource.Size - 1
                tp1 = Trim(DBSource.GetValue("Code", x))
                tp2 = Trim(DBSource.GetValue(3, x))
                co.ValidValues.Add tp1, tp2
                DBSource.Offset = x
            Next
- at the 'co.ValidValues.Add tp1,tp2' I receive this error
'Valid Value - The Value Exceed boundaries'
- tp1 max value is of 8 Char
- tp2 max value is of 50 Char
I've try to insert manually the value like validvalue.add "101","23123123....213" and it work correctly..
where is my error??
Bye!!
PS: Sorry for my english

Hi,
There's no problem with your code itself (however you don't need to set the DBDataSource offset, if you are only filling the ComboBox - GetValue picks the right data anyway...). It works fine (at least with 2004 PL23 + 2005 Build 119).
Looks like a problem with your data (or some "old" bug, but this would be the first time I heard about it...)?
...or did you solve it in the meantime?

Bind user generated info to DataGrid & edit with comboboxes

In my app, the user enters data which gets stored into a
class. I then wish to display this info in a DataGrid with three
columns corresponding to the data entered (2 strings and 1 number).
Is there an easy way to get this into the DataGrid by using binding
or do I have to do manual insertion of the data?
Also, I'd like to let the user edit the DataGrid. But I don't
want him to be able to just type whatever he wants, I'd rather give
him a pop-up or combobox with the relevant options.
Any suggestions about this approach?

When you say the data gets stored in a class, do you mean an
object? One way would be to store the data in a user data value
object and then bind the object parameters to your DataGrid. If
there are multiple users, you could put the object in an
ArrayCollection and bind that to your DataGrid.
You could then use an itemRenderer or itemEditor for each
column that would allow the user to update the values with
comboBoxes and the updates would be reflected in the stored object.

Problem with comboBox editor

Hi experts,
i am keeping a combobox renderer and editor in my JTable for 2 columns say 5th column and 7th column.
In renderer no Problem.
But while i am editing ,whenever i am choosing a perticular item from the drop down in the first row of table,it is affecting the remaining set of rows.,not all the rows also.
for example,next 5 rows are getting the same selected value.
next some 2 rows are getting affected.
the below 2 class are my renderer and editor.public class ComboBoxRenderer extends JComboBox implements TableCellRenderer {
        public ComboBoxRenderer(String[] items) {
                        super(items);
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                if (isSelected) {
                // Select the current value
                setSelectedItem(value);
                return this;
}My ComboBox editor is public class ComboBoxEditor extends DefaultCellEditor {
        public ComboBoxEditor(String[] items) {
               super(new JComboBox(items));
}so i am using this render and editor in my swing screen by the following codeString strSP[] = {"P", "O", "H", " "};
column5.setCellEditor(new ComboBoxEditor(strSP));
column5.setCellRenderer(new ComboBoxRenderer(strSP));I am sure like the problem with my renderer and editoronly,but i am helpless.
Please if someone help me to come out of this problem,it will be much helpful for me .
thanks

Hi,
Thanks for u'r reply
I tried in so many ways.
I tried with u'r editor,and sun forum examples also.
I brief what i want.
I am having table with 3 column.
The zeroth col, and the 2 col is a combo box.so i am rendering.
when i choose a one from zeroth col combo Box ,the 2nd col ComboBox value has to change into YES
when i choose a apart from one from zeroth col combo Box ,the 2nd col combo Box value has to change into NO.
Here my Problem is
When ever i am choosing the particular value from the 1st combo box,it is affecting the all the combobox values below(set of values,not all)..To solve that i kept the commented line in the renderer but it is creating the new problem.
I am very seriously working to solve this problem,if any one suggest to solve this,it will be very much helpful to me.

Custom exception problems with ADF framework

Hi,
I have problems with the exception handling in an web service Java class (POJO).
In this class I throw my own exception WsException-class which extends the normal Exception-class.
The class WebservicesAppModule extends the oracle.jbo.ApplicationModule.
In the following I first describe the web service class and then the three tests a)-c).
In test b) you can find my main problem.
Web service Java class (POJO):
public Element check(Element element) throws WsException{
WebservicesAppModule am = null;
try {
// 1) system error
// if I comment the next line out, then am = null and a NullPointerException is thrown which appear as NullPointerException in the SOAP response
am = (WebservicesAppModule)Configuration.createRootApplicationModule(_am,_cf);
if(value == null){
// 2) application error
WsException wsex = new WsException();
wsex.addErrorCode(WsException.C_INVALID_BANK_CONNECTION);
throw wsex;
} else if (value2 == null){
// 3) explicit system error
throw new NullPointerException();
}catch(WsException wsex){
// 4) application error
throw wsex;
}catch(Throwable ex){
// 5) system error
log.debug("Technischer Fehler", ex);
WsException wsex = new WsException("system error");
wsex.addErrorCode(WsException.C_NOK);
throw wsex;
} finally {
if (_am != null) {
Configuration.releaseRootApplicationModule(am, false);
Test a):
- The WebservicesAppModule is initialized (1)
- value = null, so the process run in the "application error" if-block (2)
- The WsException is thrown and catched in the "application error" catch-block (4)
The SOAP repsonse is okay:

Customized KeyboardFocusManager problems with JOptionPane-Dialogs

Hi,
I have a problem I'm not able to solve: With Java 1.4.2 unter Linux, as well as all newer Java Versions (1.4, 1.5, 1.6) under Windows, dialogs created by JOptionPane.showXXXDialog do not react to keyboard events like <Tab> any more when using a customized KeyboardFocusManager. Java 1.5 and 1.6 under Linux work fine.
Here is what I did:
I have a JFrame and want some customized focus control when navigating through the Frame with <Tab>. Therefore I've implemented a class
public class EfaFrameFocusManager extends DefaultKeyboardFocusManagereand said in the main JFrame:
EfaFrameFocusManager myFocusManager = new EfaFrameFocusManager(this,FocusManager.getCurrentKeyboardFocusManager());
FocusManager.setCurrentKeyboardFocusManager(myFocusManager);The constructor of my EfaFrameFocusManager stores the JFrame (this) and the original KeyboardFocusManager (2nd arg) for later use. Within my own FocusManager, I've implemented the method
public void processKeyEvent(Component cur, KeyEvent e)which is checking whether the desired Frame (efaFrame) is currently active or not. If it is active, it's performing my customized operations which is working well. If it is not active (e.g. because a dialog created with JOptionPane.showConfirmDialog() is open), it should perform default actions. So I said within processKeyEvent:
if (!efaFrame.isActive()) { // efaFrame is the previous "this" arg
fm.processKeyEvent(cur,e); // fm is the previously stored CurrentKeyboardFocusManager
return;
}Instead of invoking processKeyEvent on the original KeyboardFocusManager fm, I also tried super.processKeyEvent(cur,e);, but without any change in behavior.
As I said before, this is working well under Java 1.5 and 1.6 with Linux.
However, it is not working unter Windows (any Java version I tried, including 1.4, 1.5 and 1.6) and also not unter Linux with Java 1.4. With these combinations, dialogs created by JOptionPane.showXXXDialog(...) do not respond to the <Tab> key. I do see that my own FocusManagers processKeyEvent method is invoked, and I also see that it invokes the one of the original FocusManager, but the Dialog doesn't react.
What am I doing wrong?
Nick.

I have a JFrame and want some customized focus control when navigating
through the Frame with <Tab>. sounds like you should be doing this via a FocusTraversalPolicy

Custom Tag -- Custom Component problems with iframes

I have a "project" component that originally iterated over a list of models and created/renderered the corresponding (and fairly complex) interactive UI components for those models. On the client-side, the output from these were then organized neatly into "tabs" via CSS ... all on one page. Since these UI Components are so hefty, when any iteraction was done on one of them, the whole page had to re-render and things got just plain slow. To get around this limitation, I decided to have my "project" component no longer create the UI components himself, but instead generate an IFRAME that points to a page that will generate a single component. This way, any iteraction will just cause that single IFRAME to refresh.
Due to the fact that an IFRAME can only be populated by using the src attribute, I have created a page that contains a JSF View (<faces:view>) and inside is a single custom tag of mine (<mine:displayView>). Let's call this page singleDisplayView.jsf. I create iframes that point to singleDisplayView.jsf with different request params for each (singleDisplayView.jsf?modelName=Foo, singleDisplayView.jsf?modelName=Bar, etc.)
The displayView tag has one attribute called requestQueryString and I use the tag like so:
<t:displayView requestQueryString="<%=request.getQueryString()%>" />The displayView tag's class is DisplayViewTag. In DisplayViewTag::setProperties(UIComponent uiComponent) method, I get the model name out of the request map and set this property on the UIComponent.
The problem is that I'm noticing that as the main page (that contains these frames) loads, setProperties() is only being called twice. After that, the components created by subsequent iframes just seem to be using the modelName from the second frame.
Is there a syncronization issue I don't understand?
Any ideas?
Any help would be much appreciated.
Thanks in advance,
Mark

On a possibly related note, I read this in an article of the JSF application lifecycle:
In the first phase of the JSF lifecycle -- restore view -- a request comes
through the FacesServlet controller. The controller examines the request and
extracts the view ID, which is determined by the name of the JSP page.Could it be that the lifecycle is trying to reuse components from a single view, since all these iframes are pointing to the same page?

2007A - Problem with Combobox.Selected with an empty value

Hi all,
I 've tried to launch my add-on created with SBO 2005 SP1
on 2007 client.
I've a problem when I try to do
myCombobox.Selected.Value
when the valid value is empty.
Selected is null and I've an error.
So I must test each Combobox by doing this :
if( myCombobox.Selected is null)
But I've hundreds of this case in my code.
Does an another solution exists?
Thanks

you have the same problem in every business one version.
you first have to check if the property is not null/nothing
the only other way is that you use try / catch
value = oform.Items.Item("cmb1").Specific.selected.value()
Catch ex As Exception
value = ""
End Try
but the effort is the same for you

Using xml with datagrid - problem with element attributes ...

Hi,
When i try to set the datafield in a DataGridColumn to an
attribute, ex.: @isPermaLink - the value is not printet in the
datagrid?
My code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="

</mx:Panel>
</mx:Application>
I hope someone has a tip ....
Best regards,
Kristian Thrane

Hi Kristian,
I'm with some problems, a bit alike yours, but from what I've seen, I would recomend you to see type errors...does the atribute "isPermaLink" inside the "guid" tag, or "title" tag?
My problem is the opposite of what you have... I can place tag attributes in a datagrid, but I can't put in the same Datagrid the tag value. But I have no choice since the feed comes from a public webservice.
My feed is:
<search ver="3.0">
<loc id="BRXX1094" type="1">Aveiro, Brazil</loc>
<loc id="POXX0006" type="1">Aveiro, Portugal</loc>
</search>
<mx:DataGrid x="10" y="53" width="365" id="dgLocation" dataProvider="{wSearch.lastResult.loc}" itemClick="callService(event);">
<mx:columns>
<mx:DataGridColumn headerText="Localidade" dataField="loc"/> //This doesn't work
<mx:DataGridColumn headerText="Referência" dataField="@id"/> //This does
</mx:columns>
</mx:DataGrid>
Hope it give you any ideas.
Beste regards

Truly Terrible Customer Service- Problems With Lenovo U410

Hello everyone,
I would like to share my Lenovo Customer Service experience.
While on holidays in Poland last August, I decided to buy a new laptop in one of the big electronic stores. The laptop, however, developed a fault on the second day. I thought it was a case of bad drivers causing the problem. After I returned from my holidays, the fault was still there.
I contacted the Lenovo Customer Service who requested a proof of purchase. I explained that the laptop was bought in Poland on holidays and sent them on the receipt. A day later, I got an email saying:
"Your machine has been booked in for a full repair at our service centre. Thank you for your proof of purchase.
In 2-3 working days you will receive a letter containing instructions regarding the booking of your collection. The letter will also contain very important terms and conditions in particular with regards to data loss.
Please follow the instructions and your machine will be repaired under warranty."
A few days later the machine was taken off me by a DPD courier for almost 2 weeks. In the meantime I had no other option but to use my father's laptop to do my final year college project.
I was delighted when I got the email:
"We have completed the servicing of your item.
Your item is now being packed and prepared for dispatch. You can track your package online..."
However, 30 mins after using the "newly repaired" laptop, the stripy screen came back! Needless to say, I wasn't happy. I contacted Lenovo again, their customer service agent apologised for the bad experience and said that the laptop will need to be sent back again. For me that meant another 2 weeks without the laptop!
This Tuesday, I finally received the laptop back. After using the laptop for an hour or so, the horrible stripy screen appeared in front of my eyes! This time I was absolutely infuriated!! The laptop was sent back twice and the same problem persisted. I got my phone and rang the Customer Service to ask what the hell is happening?!
The answer I got this time was that the laptop was purchased in Poland and therefore it is not covered by the International warranty!! A few months of dealing with the company, a couple of phone calls and sending the laptop off for a repair twice to be told that they didn't fix it because the machine is not covered by the International Warranty?!
This is my short story of my terrible customer experience! I am not satisfied with the way this company operates, takes my laptop off me, sends the laptop off to their repair centre in Germany to then say that they cannot fix it?! Could anyone who works for Lenovo please explain to me where is the logic in that?

I find it absolutely deplorable of Lenovo that there has been no posted response to this customer service issue. I have been trying to decide for a while now if it was worth purchasing a Yoga 2 Pro as it looked to have all the specs of a PC Hybrid I was hoping for. Well....how wrong could I have been...I had no idea how appalling the customer service is from this company!
Firstly, in the UK...there have been some nightmare stories of faulty items and ridiculous product shipping delays that just seem to keep changing without any thought for the consumer in explaining what the hold up is. If you want to see a fantastic daily updated example of this alone just have a look at the Lenovo UK Facebook product page. Just reading it for ten minutes is tragic. There are so many upset customers in there that it almost seems comical.
The shipping delays are pathetic, they will glady take people's money (including warranties on items that arent there!) and hold it in the Lenovo bank accounts but the slow service and response to those with faults displays a complete disregard for the consumer. I can understand a company being unable to keep up with high demand of a product if it is very good and in demand but this needs to be addressed with admission in communication. Simply advertising a product that people cannot access and dealing with the irate customer-in-waiting afterwards is not acceptable.
Let it be known that Lenovo through their own incompetence have lost a customer before he even purchased anything today. I can only hope that others considering making a purchase will see further posts like this and feel deterred in the same way. That way, Lenovo may finally see that they really need to up their game in terms of service and quality control. To the person that made this post, I can only feel sympathy for the problems you had with them and can only say that you are certainly not alone! Check out their UK Facebook page to see just how terrible the service is (including choosing to ignore the more upset customers while blowing the trumpet whenever someone's problem is "sorted"!).

I have a similar problem. I have got the combobox in the jtable working (when i switched off the labels). Everything seems to works except when I select the first record in the combobox. When I tab out of the cell it becomes empty. If I first select a different record( 2-n) and then the first record the value remains when I tab out of the cell. This also looks like a bug to me. Here's my binding code:

Performance problems with combobox and datasource

We have a perfomance problem, when we are connecting a datatable object or something like this to a datasource property of a combobox. Below you find the source code. The SQL-Statement reads about 40000 rows and the result (all 40000) should be listed in the combobox. There is duration about 30 second before this process has finished. Any suggestions?
Dim ds As New DataSet
strSQL = "Select * from am.city"
conn = New Oracle.DataAccess.Client.OracleConnection(Configuration.ConfigurationSettings.AppSettings("conORA"))
comm = New Oracle.DataAccess.Client.OracleCommand(strSQL)
da = New Oracle.DataAccess.Client.OracleDataAdapter(strSQL, conn)
conn.Open()
da.Fill(ds)
conn.Close()
Dim dt As New DataTable
dt = ds.Tables(0)
ComboBox1.DataSource = dt
ComboBox1.ValueMember = dv.Table.Columns("id").ColumnName
ComboBox1.DisplayMember = dv.Table.Columns("city").ColumnName

But how long does it take to fill the DataTable?
I can fill a 40000 row datatable in under 4 seconds.
DataBinding a combo box to that many rows is pretty expensive, and not normally recommended.
David
Dim strConnection As String = "Data Source=oracle;User ID=scott;Password=tiger;"
Dim conn As OracleConnection = New OracleConnection(strConnection)
conn.Open()
Dim cmd As New OracleCommand("select * from (select * from all_objects union all select * from all_objects) where rownum <= 40000", conn)
Dim ds As New DataSet()
Dim da As New OracleDataAdapter(cmd)
Dim begin As Date = Now
da.Fill(ds)
Console.WriteLine(ds.Tables(0).Rows.Count & " rows loaded in " & Now.Subtract(begin).TotalSeconds & " seconds")
outputs
40000 rows loaded in 3.734375 seconds

WCF-Custom performance problem with large response messages

We're trying to debug a performance issue in Biztalk 2013 when using a WCF-Custom adapter to call en external WCF-enpoint.
From a Biztalk orchestration we're calling en external WCF-service to retrieve an xml message sometimes containing a lot of Base64 encoded data. The response message can be up to 10Mb in size. The send port is very slow in retrieving the response
and a 10Mb message can take up to 3min to retrieve. For comparison we've made a console program with the same service reference and binding as the Biztalk adapter uses and we can retrieve the same message in about 3 seconds.
The WCF is using binary encoding over http and we've set the maxMessageSize, maxBufferSize and maxBufferPoolSize to Int32-MaxValue. We realise that using Biztalk there will be overhead because the message is put into the message box but we're unsure how
to improve the performance of the send port.
Any suggestions?

Hello,
There are certain Optimization you can do with your BizTalk.
1)The first thing that I would do is to check the BizTalk SQL server jobs are running correctly
(SQL Sever Mgmt Studio –> SQL Server Agent –> Jobs). Lookout for the jobs with the word “CleanUp” in them.
2)Another check that you could do is to verify the entries in the Spool table
(Database[@Name='BizTalkMsgBoxDb']/Table[@Name='Spool']). Ideally, the number of entries should not be HUGE
(as in not over 100/200 entries)
3) Create seperate host and host handler for your send Port.
4) Set The MaxReceiveInterval from adm_service(BizTalk Management DB) class table 100 ms from 500(By default).
5)Increased the Throttling Settings Internal message queue size to 1000 from 100 In new Application Host.
6)Set the Maximum number of messaging engine threads per CPU to 40 (By default it is 20).
7) Add Max connection in your BTSNTSVC.exe.config file
<system.net>
            <connectionManagement>
                        <add address
= “*” maxConnections = “300” />
            </connectionManagement>
</system.net>
For other setting you can look for BizTalk Optimization Guide
http://www.microsoft.com/en-ca/download/details.aspx?id=10855
Above setting are for generic performance enhancement purpose.
Note: You can verify through Orchestration debugger or Orchestration tracing how much time send port is and pipeline is taking to publish the message to Biz Talk again .
These will give you better picture what more settings you need to apply .
Thanks
Abhishek
