Problems with 2 tables on same page (in tabs)

i have two data tables bound to different data providers on a page
the tables are presented in two of the tabs of a 5 tab tabset
both tables bind to the data, refresh etc fine. i can customise the data, sort the tables, paginate and so on. no problems.
however, both tables have an edit and a delete button. on table 1 these buttons work fine and fire the appropriate event handlers. on table 2 the buttons i have added to the second table don't seem to fire any event when they are clicked - i have run in debug mode and nothing is happening when the buttons are clicked at any point in the code that i can find
has anyone had similar problems - anyone got any suggestions
thanks
ben

Thanks Misha, for the help
I actually ended up tracing it back to an issue with the data provider - essentially, I had changes some of the table structure behind the data provider and this seemed to cause the table in question to not fire the button events - it seemed that because part of the compound primary key was not selected in the data provider's source rowset, the provider could not get a row key and therefore the events did not fire - i have it working now though after modifying the backing query
thanks again

Problem with Applets in same page

Hai to all,
I am having a problem with GUI in applets
My first class extends a JPanel named A_a
import javax.swing .*;
import java.awt.*;
import java.awt.event.*;
public class A_a extends JPanel
JButton jb;
JTextArea text;
public A_a()
setLayout(new FlowLayout());
jb=new JButton("Click me");
//add(jb);
text=new JTextArea(5,20);
add(text);
public void text_appendText(String aa)
System.out.println("I AM IN A_a");
text.append(aa);
text.revalidate();
revalidate();
/*public static void main(String ags[])
A_a a = new A_a();
JFrame frame=new JFrame();
frame.getContentPane().add(a);
frame.pack();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) { System.exit(0); }
frame.setSize(200,200);
frame.show();
and then I am using other class B_b which is an applet carries a exitsing panel (A_a) inside it .
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class B_b extends JApplet
public A_a a;
public void init()
a=new A_a();
getContentPane().add(a);
public void text_appendText(String aa)
final String aaa =aa;
new Thread(new Runnable()
     public void run()
          a=new A_a();
          a.setBackground(new java.awt.Color(255,200,200));
          System.out.println("I AM IN B_b");
          a.text.append(aaa);
          a.text.revalidate();
          getContentPane().remove(a);
          resize(500,500);
     }).start();
and the I am using the second applet C_c in which by performing a button action the old panel A_a should get removed and replace the new panel D_a (which is not here )in the applet B_b with all other components(namely button , text fields etc)
import javax.swing .*;
import java.awt.*;
import java.awt.event.*;

public class C_c extends JApplet implements ActionListener
JButton jbt;
JTextArea jta;
public void init()
getContentPane().setLayout(new FlowLayout());
jbt=new JButton("Click me");
jbt.addActionListener(this);
getContentPane().add(jbt);
jta=new JTextArea(5,20);
getContentPane().add(jta);
public void actionPerformed(ActionEvent ae)
Enumeration e = getAppletContext().getApplets();
Applet applets = null;
          while(e.hasMoreElements())
               applets=(Applet)e.nextElement();
               if ( applets instanceof B_b)
                         System.out.println("I AM CLASS C_c");
                         ((B_b)applets).text_appendText(jta.getText());
                         ((B_b)applets).remove());
                         ((B_b)applets).getContentPane().add(D_d);
both the applets C_c and B_b are in same browser page
How can i achive that pls help .

Problem with tables spanning multiple pages

I have used Pages early on before Numbers to track my small business expenses vs income. I use tables to manage this by clicking outside the page so it can be unrestricted by text fields but it creates a problem.
Problem: free floating tables when rows continue past the footer, don't auto format onto another page.
Needed solution: How do I format the table so it automatically formats the total bar onto the next page without changing my existing layouts?

Problem with table formatting

I'm having a lot of problems with tables not reflecting their formatting when I open them in a browser. I've tried opening in Safari, Firefox & Camino with the same results. For example, a row with the following html content has a much larger height & aligns the text to the top when opened in a browser:
<tr>
          <td height="15" colspan="3" valign="middle"><h6 align="center">Summer 2009</h6>
          </td>
        </tr>
If it matters, this is a row in a table nested in another table. Here's the code down to the row in question (all tags are closed properly in the remaining code):
<table width="600" border="2" align="center" cellpadding="0" cellspacing="0">
    <tr>
      <td align="center" valign="top"><img src="images/events.jpg" width="250" height="35"></td>
    </tr>
    <tr>
      <td align="left" valign="top">
      <table width="100%" border="0" align="center" cellpadding="1" cellspacing="0">
        <tr>
          <td height="15" colspan="3" valign="middle"><h6 align="center">Summer 2009</h6>
          </td>
        </tr>
I am using a style sheet for text. Here's the code for "h6" if that matters:
h6 {
font-family: Verdana, Geneva, Arial;
font-size: 14px;
font-weight: bold;
color: #660099;
Any ideas is appreciated. This is driving me nuts. Spacing and alignment sometimes work and sometimes don't work. Dreamweaver is supposed to make such things easier!
Kevin

Header tags are usually used round a bit of text, not parts of a table, and if you don't specify the margins on them, can force different amounts of space below in different browsers. Try making the bottom margin on h6 zero, and confine it to text within a cell.
Also, if you can upload your page somewhere and let us have the url it will be easier to troubleshoot.

Using VO as form and table on same page

Hi,
We are facing some issues while using same view object on one page. The view object is dropped as input form and as table on same page. There are few fields in the input form that have autosubmit property set to true. Now while entering the data into form, after clicking any autosubmit field, if we refresh the page, then new row gets created in table with value of the auto submit field. This is in cache only and not created in DB. We tried by exposing two instances of same view object in application module but still same issue. Finally we created two view object, one which is EO based and another ready only through query. Its working fine now. But is there any other possible solution, without creating two view objects?
Jdev: 11.1.1.6.
Thanks

Hey Ami,
I've tried understanding your problem but i'm not sure if i could.
The problem is that you can insert via the form but it doesn't update the table ?
Is that it ?

Frederico.

There is no need to download anything to solve this problem.
You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

Really having problems with organising documents in pages. For example, deleting pages deletes the whole section and I cannot insert a section break as its greyed out & sending an object to background deletes several pages - what the **** is going on???

Really having problems with organising documents in pages. For example, deleting pages deletes the whole section and I cannot insert a section break as its greyed out & sending an object to background deletes several pages and trying to insert a text box autmatically creates new pages- what the **** is going on??? Is this programme really this badly thought out? I thought everything apple was supposed to be intuitive!?!?!? Help.

You can not insert a section break into a textbox.
You appear to have a lot of objects with wrap set, that once you take them out of the flow of text (by sending them to the background) causes the text to reflow and contract into fewer pages. Pages is almost unique in the way it forms up pages in Word Processing mode only so long as there is text on them.
I suspect you probably have hammered away at returns, spaces and tabs as well to position things, which only works to add to the mess.
Download the Pages09_UserGuide.pdf available under the Help menu and swot up a bit on how it works.
You may find this a usueful resource as well:

PS There is quite a lot of programming in OSX that is far from "intuitive". Pages is easy at one level, when using the templates, otherwise it can be quite frustrating.

Problem with table MBEWH

Hello SAP experts , im having a little problem with table MBEWH because the data i whant to extract isnt the correct one, i saw that this table stores all the prices for the materials and it groups them by year and by month but when i check to see what was the price for a specific material the price i had on that time periord inst the same as the one on the system, also i manage my material with baches and when i check to see if that batch was in that period of time it isnt so im really confused as to how the system saves the historical data on this table, thank you in advanced.

Problem with table paging [PDK for NET]

Hi All,
I have a problem with table paging in PDK for .NET (ver 2).
The Table has 14 visible rows.
The lead selection is set to "SINGLE"
When the user selects a row I can use
Table1.SelectedKeys(0) Mod Table1.VisibleRowCount
in order to get the info of the selected row.
If I will page using the "Prev/Next" page of the Table UI element it will also work.
However, when I press "Prev/Next" item and then select a row it chooses the wrong row.
(See picture: http://img509.imageshack.us/img509/3882/table5tq.jpg)
What can I do in order to solve the problem?
Thanks,
Omri

Hi Omri,
how are you doing ?
The SAPTable is similar to a DataGrid control and need to be bound to the datasource on every postback
a good idea is to keep the dataset available in the page or on the server ( so that you dont need to keep making expensive fetch operations
The selected row is affected by the recordset (dataset) and needs additional programming
A work around for the selected row issue is to save it in a server side hidden variable (or anything that will persist) and read and set the value in the page / next button handler
with respect,
amit

Problem with tables -- need help!

I am having problems with table formatting, when using
Preformatted text. The tables look fine in the WYSIWYG editor, but
have lots of extra space above and below the text when looking at
the output files.
I will attach the code from one of the HTML files from my
project, so you can see what I'm talking about.
Thanks.

Well, if you're talking about the single-celled table with
the line:
<p class=Preformatted>[assembly:
Ace.AceAssembly]</p>
</pre>
... you can eliminate the <P> tags. that will give you
one line less. Otherwise, your remaining space is the result of the
<PRE> tag. It, like the <XMP> tag, gives it one line of
space beneath as well.
Your alternative beyond that would be to, when needed, wrap
up the script in Javascript. That line, for instance, wouldn't need
it.

What could be the problem with table REGUH

the below query is taking more time.
in quality even i have taken slection criteria which is very less than devlopment selection.
please tell me the below query is performance wise not good or
is there any problem with table REGUH in quality system?
IF NOT ( t_bsak_aux[] IS INITIAL ).

Hi,
Using SPACE against the keys (LAUFI, LAUFD - specifically LAUFD) will most likely return no results. LAUFD, being one of the keys and the date which the program is supposed to run (considering that this is settlement data - it has already run) - implies that this field will be populated. Putting " = SPACE" in your where clause is saying that you want to find records from the table where those fields are not populated. That is fine for LAUFI, considering it is the indicator for a proposal only. In my requirement, my client did not want to see proposals but only real payment runs - therefore, LAUFI = SPACE is correct.
The reason you are having poor performance while selecting form this table is because it is a cluster table like bseg. This thread explains a little bit of why cluster tables are a performance nightmare when trying to select - although it is about bseg, you will get the idea:
http://blogs.ittoolbox.com/sap/db2/archives/select-from-bsegrfblg-performance-problem-14247
I'm trying to find an alternative to get bank account information regarding payments - I will post a reply if I am lucky to find one!
Good luck

REAL problems with iMessage activation same with Face Time

I'm having real problems with IMessage activation same with FaceTime, the phone shows the activation is being made but it does not activate!
Apple ID and password is OK, it's working with other applications
Any ideas guys?!

My daughters had the same problem with both of their iPod Touches. One logged back into iMessage and FaceTime, the other consistently would not login with the same error, "An error occurred during activation. Try again."
Check your date and time. Its likely incorrect. Once the date is corrected. Restart the device.
For what ever reason, some devices lose track of the date. In my case, apparently, my daughters change the date to affect a particular game by advancing the date. Little cheaters. (LOL)
Hope this helps!

Problem with Table control lines

Hi Friends,
This is the problem with table control lines:
I have screen with table control and I would like change the table control lines dynamicaly.
Exp:
In my PBO the Internal table which I am using to loop the TC is havig 7 records and its displayed with 7 records, now I have added one more record into my ITAB and now ITAB is having 8 records, when I am looping this ITAB with TC its taking the TC lines 7 only.
here is the code:
Initial values in gt_scr400 = 8
Initial values in tc_scr400 = 8
Now added one more recor into gt_scr400 , now gt_scr400 = 9.
LOOP AT   gt_scr400
       INTO wa_scr400
       WITH CONTROL tc_scr400
       CURSOR tc_scr400-current_line.
ENDLOOP.
I have used this logic :
DESCRIBE TABLE gt_scr400 LINES g_rec_300 .
tc_scr300-lines = g_rec_300.
but its not modifying the lines in my table control.
How to change the TC lines based on ITAB total records.
Thanks,
Sridhar

there is a field in TableViewName-xxx
don't remember the exact field name for (total no of records)
you can check it in debug. when you add records in Internal table, u need to modify this field which is set at the first time when table control is populated.
