Method called more than once - and dies with EXC_BAD_ACCESS error

Hi,
In my app, I have 4 views with their respective viewControllers. In the appDelegate.m, I provide methods that allows to switch to any of these views. Following is code for switching to the editView:
-(void) flipToEditView {
[self populateTheList]; // populate an array
EditViewController *anEditVC = [[EditViewController alloc] initWithNibName:@"EditView" bundle:nil];
[self setEditVC:anEditVC];
[viewController.view removeFromSuperview];
[self.window addSubview:[editVC view]];
[anEditVC release]; }
The view is not switched - and moreover, this method is called more than once; and the app dies with EXCBADACCESS!

QuickTime DOM Events called more than once?

I am in the process of writing code in JavaScript that will track the interaction on a embedded QuickTime video.
function ew_addImage(v) {
trackImg=new Image(1,1);
trackImg.src=v;
function ew_pauseTrk() {
var imgStr='http://www.sldkfjsldfjk.com/200125/EWTRACKNEW_VINT?ewadid=751801&ewbust='ewbust'&eid=1078554&file=$VIDEO$&bw=56&vlen=3:00&vint=PAUSED';
ew_addImage(imgStr);
if (document.addEventListener)
document.getElementById("mov1").addEventListener("qt_pause", ew_pauseTrk, false);
Everything works correctly. I am able to see the image being called when I am looking at Wireshark. The problem is when I click pause more than once.. It seems like the QuickTime DOM Events can only be called once.. Is that true?
Thanks

WDDOMODIFYVIEW and WDDOPOSTPROCESSING is called more than once!

Hello everybody,
maybe someone can help me. Our WDA application consist of 5 Components. One main and 4 components embedded in it. We instantiate the components in the WDDOINIT of the main component and use them between themselves.
I suppose that's the reason that the events in the views and componentcontrollers of each component is called so often.
With a break point in a WDDOMODIFYVIEW an the debugger I find out that the HANDLE_REQUEST methos from the CL_WDR_CLIENT_ABSTRACT_HTTP class is startet also more than once.
1. if m_ucf is not bound -> yes and m_request_type = suspend
2. if m_ucf is not bound -> initial and m_request_type = suspend
3. if m_ucf is not bound -> initial and m_request_type = suspend
4. if m_ucf is not bound -> initial and m_request_type = refresh
Maybe someone has expierence with it an can give a hint or explanations for this.
I hope so
Thanks for any answer
Best regards
Christian Breitenbach

hi christian.......
a wddomodifyview view method will be called even if there is a little change in your view. it will b e called more times than your normal pbo in a dynpro application. the wddoinit will be called only before the view is loaded... but the modify willbe called even for popups nad any event.

Latest upgrade of itunes doesn't start up more than once per boot.

Since the latest upgrade (can't tell what version without rebooting my laptop), iTunes will only start up once per uptime session. If I plug in my iPod Touch, it will start up automatically just once, or if I start by selecting the Start Menu item to run iTunes, it will only start up once. After iTunes is closed, I must reboot the PC if I want to use iTunes. This is with Win7, but it takes me back to the early days of Win95 or ME - ahhh what memories! I'm glad that I can look at that as being in the past, but when it happens right now, I'm not particularly glad.
I can see that the iTunes Helper is running, and even iTunes.exe is running, but there's no program window visible, no icon in the tray... it's not running as far as I can see, and it's not very useful in that state. I can't see any way other than this of letting Apple know that they've trashed the new version of iTunes as far as my computer is concerned. It's just rather unhandy to have to reboot each time after I've finished using iTUnes. As a friend of mine used to say, there's nothing so unhandy as a handy thing that doesn't work...
Help?
Blessings,
Duff

And that's true for the latest version as well - no change. The process never goes away after I close iTunes - it just hangs around slowly getting bigger and bigger memory-wise. Plug in my iPod Touch, and nothing happens - no synch, nothing. If I kill off the process, then plug in the iPod, iTunes does start up, but it just hangs there, and never becomes truly running and useful. So, I don't know what "fix" broke my iTunes, but it's still requiring a reboot to get it working after it's been used once and closed. At least Win 7 boots pretty quickly on my laptop...

Function module In Update Task is called more than once

Hi experts!!
I had a requirement to Create a Customer ( i will call it B) when another Customer (A) is created (ON SAVE).
I used a Badi to implement the requirement, and inside my Badi i have 2 Function Calls in Update Task.
The first one to create Customer B and the second one to send Customer's B data to another System.
Even though the second function call is inside an IF-ENDIF condition ( so that only Customer's B data are sent) the function is called twice sending the same data. My guess is that since the First Function saves the Customer to the database, that is the reason why the second Function is called twice.
Is there any way i can control how many times a Function In Update Task is called????
Please help!!
Thank you in advance!!

Hi BreakPoint & thank you for your reply!!
I tried your suggestion but even if i fill the flag during the first call the function is called twice. Looks like during the second database commit the function is called with the correct conditions met but twice.
Also while debugging it looks like it is only called once. It s very strange!
Any other ideas???

Browser does not seem to prompt for more than once per session, to accept untrusted sites. I have to close/open firefox to visit multiple untrusted sites in one sitting. Is there a way to fix?

I use firefox to connect to the console of different Sun/Oracle servers. The www pages are "untrusted" and I get a question to continue to connect or not. When I say continue, it pops up a window to either accept or deny the cert. This window, once I accept it, to continue to do my work. When I'm finished with that server and continue to another one, that window no longer pops up for me when another untrusted www page is loaded. But when I quit firefox, and then revisit the page, the dialogue pops up and I can accept the new cert and continue to work.
I'm considering going back to the older version of firefox as this is severely impacting my day to day use of it. I'm still trying to see if I can get around it by fiddling with different firefox options.

Thanks. I tested it, and found that I can create a bookmark in FolderA, and them manually copy it to FolderB, FolderC, and FolderD.
Once that is done, I tried the old method of "Bookmarks" --> "Bookmark This Page" and added it to FolderE. When I did that, it deleted the copy in FolderD but left the other three alone!
This is fine with me. I personally think this is a bug, because I don't think that Firefox should ever delete a bookmark without asking me (or at least, informing me). But now that I understand the algorithm, I can work around it. Thanks!

Can a thread's start() method be called more than once?

Is it legal/well-defined to call a Thread object's start() method after a previous call to start() has completed?
eg.
Thread t = new Thread(public void run() {...});
t.start();
t.join();
t.start(); // will this call fail?

Ok, since no one's going to answer you I will.
Yes. It won't work if you call start() multiple times and it will throw an exception on all subsequent times.
The way I work around it is to put the method in an inner-class and then create a new instance of that iner-class everytime I want to start a new thread.

If I visit a site more than once per day, that site comes up with plugins that don't work and a very altered display without photos or graphics-- can fix this by erasing all cookies and history, but am often required to do this 5x per day

Updating to latest Firefox did not solve problem.
Cannot connect to firefox live chat

I'm having a little trouble understanding the part about your password having to be reset. Why is that happening??
Let's start with Firefox's settings:
(1) You can configure the password manager feature on this tab:
orange Firefox button (or Tools menu) > Options > Security
There is a checkbox to enable/disable the feature.
There also is a "Saved Passwords" button to review and remove any passwords you do not want Firefox to keep.
That tab also has a feature to set a Master Password so that no one can use your saved passwords without knowing the Master Password. You may need to exit Firefox in order for Firefox to ask for that again.
Related articles:
* [[Password manager - Remember, delete and change saved passwords in Firefox]]
* [[Use a Master Password to protect stored logins and passwords]]
(2) Site-specific permissions
If you want to use the password manager for other sites but NOT a particular site, you can configure that in the Permissions Manager.
In a new tab, type or paste '''about:permissions''' in the address bar and press Enter.
After the page loads, use the search box in the upper left corner to narrow down the list to the site you want to configure. Highlight the site on the left side, and on the right side, choose Block under Store Passwords.
(3) Form autocomplete suggestions
Separate from passwords, Firefox remembers entries you've made into forms (in most cases) and lists the matching ones below the form field in a drop-down.
To clear a suggestion, press the down arrow key to highlight it and press the Delete key.
To turn off this feature, see this article: [[Control whether Firefox automatically fills in forms with your information]].
To review and selectively edit or delete form history entries, you need an add-on. For example, you could try this one: https://addons.mozilla.org/firefox/addon/form-history-control/

Performance... Why a function column in a view is executed more than once...?

Why a function column created inside a view is executed more than once when called more than once?
EXAMPLE:
create or replace view aux1 as
date_column,
any_function(date_column) column1
from any_table
create or replace view aux2 as
column1 c1,
column1 c2,
column1 c3
from aux1
select * from aux2
It will execute 3 times the function any_function... logically the value will be the same for all columns...
I understand why!... are 3 calls... but...
Why not to create a "small" verification and if the function column was execute replace the second, the third... value? ... instead of execute 3, 4... times...
tks
Braga

Actually, this is more than a performance issue. This is a consistency problem. If the function is NOT deterministic then you may get different values for each call which is clearly not consistent with selecting 3 copies of the same column from a row. Oracle appears to have fixed this in 9i...

How to call the same query more than once with different selection criteria

Hi,
Please do anybody know how to solve this issue? I need to call one query with the fixed structure more than once with different selection criteria. For example. I have following data
Sales organization XX
                     Income 2008 Income 2009
Customer A       10                 20
Customer B        30                  0
Sales organization YY
                     Income 2008 Income 2009
Customer A        20                5
Customer B        50                10
Now, I need this. At the selection screen of query, user fill variable charakteristic "Sales organization" with interval XX - YY, than I need to generate two separate results per sales organization, one for Sales Organization XX and the second for SO YYwhich will be displayed each on separate page, where result for SO YY will be dispayed under result for SO YY. Are there some options how to do it for example in Report Designer or WAD or with programming? In Report Designer is possible to use one query more than once, but I dont know how to force each query in RD to display result only for one Sales Organization, which will be defined in selection screen.
Thank you very much
J.

Hello,
thanks to all for cooperation. Finally we solved this issue with the following way..
User fill appropriate SO on the selection screen, which is defined as range. This will resulte, that selected SO are listed in report below each othe (standard behavior). Required solution we achieved with the Report Designer, we set page break under each Result row of RD. This caused, that report is divided into required part per SO, which are stated each on separate page.

Since I updated to iCloud, Mail on my MacBookPro 10.6.8 has been unable to connect to MobileMe more than once or twice per day. Mail on my iPhone 4 has no problems. What's wrong?

Since I updated to iCloud, (which may or may not be related) Mail on my MacBookPro 10.6.8 has been unable to connect to MobileMe more than once or twice per day. Mail on my iPhone 4 and my old iMac has no problems. When there is no service a yellow warning triangle appears adjacent to the Inbox and Connection Doctor reports,"Trying to log into this MobileMe IMAP account failed. Verify that username and password are correct." Since it does fetch Mail from time to time they cannot be wrong.... can they? Should I update to 10.7 and if so what does that entail?

You have been using MobileMe's email settings, which sometimes continue to work for a time after migration but then get turned off. iCloud's mail server settings are different. Strictly speaking Lion 10.7.2 is required for iCloud, and on that Mail is set up automatically.
Snow Leopard cannot access most of iCloud's facilities, however you can set Mail up manually to access your email. The method is described here:

ORA-00604 & ORA-30512 CANNOT MODIFY TABLE MORE THAN ONCE IN A TRANSACTION

We have a requirement where two tables should be in sync at any given point
in time with respect to the structure of the tables.
Any change on table/column via ALTER (MODIFY, ADD, RENAME COLUMN, DROP

ALTER TABLE ABC MODIFY COL1 VARCHAR2(11);
and also the rest of the operations
ALTER TABLE ABC ADD COL2 VARCHAR2(20);
ALTER TABLE ABC RENAME COLUMN COL2 TO COL3;
ALTER TABLE ABC DROP COLUMN COL3;
The issue is while reducing the size of VARCHAR2 columns, while the rest of
option works fine.
Any suggestion or workaround please.

It looks like a bug to me. The failing statement from the SQL trace is

Calling thread.start() more than once concurrently

Hi, I got a simple doubt that may feel awkward or absurd to people who are well versed in the java threading concepts. I just thought of it and as I couldn't get an easy answer I am posting this.
Consider a class that implements the runnable interface. The run() method of the class is implemented with just a System.out.println(). If I make an instance of this class, say 't' in the main method and calling t.start() susequently twice or thrice; an illegal ThreadStateException will be thrown. The code snippet is as follows:
ThreadTest t = new ThreadTest();
t.start();
t.start();
It is understood that state of the thread object is changed to run state and so, if it is again started, it must be thrown. So if I put a Thread.sleep() inbetween these two subsequent calls assuming that the main method thread will be sleeping. So there is sufficient time for the first thread to terminate and then only the second will start - still the same exception is being thrown. I tried putting the synchronized qualifier for run too, still no effect - the same only happening. Why the java thread object is made in such a way that once the thread changes it state from Runnable to Running and then finally to dead state, it can be restated back to Runnable state, such that the start() method can be called again. Is it possible or not? Please post your comments.

As ejp says you can't start a thread more than once - even if it has already terminated after the first start.
By making threads a one-shot it simplifies reasoning about them: you don't have to wonder whether a second start() will work or not, depending on whether the thread has completed its first "incarnation". It also makes it easier to ensure thread resources are reclaimed. It also avoids semantic issues like whether anything about the thread is "carried over" across incarnations.
This might seem a limitation but there are many ways around it - simply don't let the thread terminate. Whatever control structure you would enforce by re-starting the thread can be emulated without letting the thread terminate in between "executions".

Count certain rows more than once

I have the sql below:
select count(*), ind_encounter
from (
select x.sak_recip, x.dte_first_svc, x.ind_encounter
from t_tmp x
group by x.sak_recip, x.dte_first_svc, x.ind_encounter
union all
select x.sak_recip, x.dte_first_svc, x.ind_encounter
from t_tmp x
where x.sak_procedure in (1, 2, 3, 4) )
group by ind_encounter
What I need to do is count the sql in bold more than once. If one row in the table has sak_procedure = 1, I want to count that row 13 times. I know that if union 11 more sqls, I will count those 13 times.
I would like to know if someone knows an easer way.
thanks for your help

try
select count(*), ind_encounter,
         sum(cnt1) -- your counter
from (select x.sak_recip, x.dte_first_svc, x.ind_encounter, count(*) * N cnt1
          from t_tmp x
         group by x.sak_recip, x.dte_first_svc, x.ind_encounter
        union all
        select x.sak_recip, x.dte_first_svc, x.ind_encounter, count(*) * M cnt1
          from t_tmp x
         where x.sak_procedure in (1, 2, 3, 4)
