DOM hierarchy will not be saved to the file
For the experienced:I try to write a class in java to create an XML using Dom I use JDeveloper 11.1.1.3. The class seems OK to me, update without problem and runs without error. But in the created file contains only one line which is the xml declaration:
< pre >
& lt;? XML version = "1.0" encoding = "UTF-8" standalone = 'no '? >
< / pre >
I was expecting the DOM tree must also be saved in the file. but it's not. The source code for the class is added as follows. Can anyone spot the problem?
Thank you very much for help!

Hello
Can anyone spot the problem?
Yes, I think:
DOMSource source = new DOMSource();
Who builds a source empty. Try this instead:
DOMSource source = new DOMSource(doc);

Vista will not display description of the file on mouse over. When I mouse over, a pop-up window displays showing: file name, Type, size and Date of change, however, it does not show the description of the file.
So, for example if I have 5 files on different types of screw - the description tells me that the size of the screws. IE. 1.5 mm or 1. 8 mm.
Update: try to get the description of the file displayed messing around in the file properties, now out of 10 records, only 2 includes the name of the file in the mice on the pop-up window. So now what lack us, it's the file name and the Description file.
Help, please...Description of the file in as long as this is not one of the available variables, which can be shown with ToolTips - but there are others who could easily serve the same purpose. Here are the options:

Document will not be saved after the page rotation
After that I turn a page, it will not save it. I have a hunch, it's safety because the latter document leave a military installation, but it let me extract pages. I don't understand. I moved the file copied in different places...
You probably change the display option, which is temporary and cannot be

try to change the text in a saved file, but it will not allow isolate me the text, place the cursor in the text box or simply go back to remove.
Hello
in what format save you your file? If it's a jpg file, then the text is compressed and unfortunately PS is telling things as they are. Even if you could change the text before you save, after having been saved in jpg format, the text is merged and is no longer editable.
A good solution is to save the files as PSD files, photoshop files. In this case, all layers are saved uncompressed and so your text will appear in its own layer in photoshop. All you need to do in this case to change it is the result of a three-step procedure
(1) select the right layer
(2) take the text tool in the tools bar
(3) mark and change your text
So the crucial question is: in what format you save your file?

VMDK not getting saved by the VCBackup for VMS V7
Hello
We did an upgrade to VI3 to vSphere4 a couple of weeks.
This week, I created a few new virtual machines that are now 7 vms.
These virtual machines are running much and have no problems.
Only downside, it's that we are more able to creat VCBackups of these machines V7, because the VMDK will not be saved.
The only files get saved are .log, .vmx, .vram and. Bah
Here's what VCbackup connects:
Current working directory: D:\Jobs\VCBBackup
HOSTINFO: See Intel CPU, numCoresPerCPU 4, numThreadsPerCore 1.
HOSTINFO: This machine has 4 cores total, 1 physical CPU and 4 logical processors.

Old virtual machines are getting backed up without any problem.
You have any suggestions?

Not be saved in the data base of page elements
Good afternoon
I hope that it is a return of holiday brain cramp but I don't see the problem... I'm working on a help desk application and when a closed ticket is displayed, a button to reopen ticket. When the button is clicked: P5_STATUS_CODE should be replaced by reopened; P5_CLOSED_BY_KEY & P5_CLOSED_DATE must be null. the record must be recorded and the page redirected on itself.
I've created a submit after process (sequence 10) that updates the fields with a condition that it triggers when the button reopen ticket (APPLY_CHANGES).
Start
: P5_STATUS_CODE: = 'reopened ';
: P5_CLOSED_BY_KEY: = null;
: P5_CLOSED_DATE: = null;
wwv_flow. Debug ("P5_STATUS_CODE value = ' |: p5_status_code");
end;
Because the button to reopen ticket has a REQUEST of APPLY_CHANGES type, it triggers the process of update DML (sequence 30). Then the branches page on itself.
Looking at the record in the database, I see that the date of modification (engine database trigger) is correct but the status code and closed fields were not updated.
When I run the form with debugging, the process works and by the debug statement, the value of P5_STATUS_CODE is replaced by Reopened. Then the process of the DML is run. And finally the branch runs.

0.03: P5_STATUS_CODE value = Reopened

I tried to change the source used on the fields still only reach and that didn't work either. Does anyone have a hypothesis as to why the fields I'm reset are not saved?
Thank you
RayIf the box is not displayed then the items are not part of the subject page and will not be part of the automatic DML. Try creating another process sequenced after the automatic DML. This process must be a simple update statement updating these columns in your table.

iPhone will not be displayed in the finder
I'm trying to move some of the photos from my phone to a file on my computer and my phone will not be displayed in the tab "currencies" in the finder. It's an iPhone 6 and it is connected through the USB port. I know this isn't an error connection because when I plug it in it costs and is trying to import my photos in the section 'photos' from my computer. I went into the settings in the finder and all turned on and it will not always be displayed. Why is this?
Because Apple has decided that OS X is smarter than you and me. They removed this option on the latest versions of Mac OS X (my devices do not appear more, grrrr...). Try instead to use Image Capture and import or remove photos from there.
