How to make ProgressBar work for long process with finally download action

Hi ADF-Experts,
i wonder if there is a adf-solution to this use case.
In my case the user clicks a context-menu item to get a report. So a background process will be started to generate the report(in pdf format) and when the generation is finished,
the user can choose to download the report in the browser built-in popup.
This all works, but because the generation process could take a long time, i want now to showing a progess bar in clock form with af:progressIndicator to inform the user about the running process.
public void clickGenerateMenuItem(event) {
startProgressBar();
generateReport();
private void generateReport() {
doGeneration();
stopProgressBar();
downloadReport();
The problem is that the ProgressBar will never be shown bacause of the call of generateReport()-methode. It is impossible in one request to make two different event (one for download and another for popup show/hide).
I also tried with af:poll together with af:progressIndicator, the ProgressBar is indeed shown but because of the native Ajax-Poll Request the generated Report can not be downloaded more.
Any idea how this problem could be answered?
Thanks in advance.
Regards
Peng

Hi,
no, you can't make to calls. But you could show an animated gif instead. Have a look at sample 027 on http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html

How to make setEditable() work for Applet

I have a program using a flag to make it work both
in JFrame and JApplet. I have a couple of JTextField
variables and I use setEditable() to set their attributes.
When I run it under JFframe, I have no problem to
edit these JTextField within panels. But when running under
appletviewer, I can not edit them at all. What could be
wrong? Thank you.

You must have added some more code...if you want my help, post the new code or a link to the new code and I or some other ppl can see what might have gone wrong.

How to make boot disk for MacBook Pro with Mavericks pre-installed

Hi -
I recently bought a new 15" MacBook Pro with Retina Display, which came pre-installed with Mavericks (10.9.0). I want to make a bootable USB disk of the system software, and have successfly used DiskMaker X (formerly Lion DiskMaker) to make the USB boot disks for Lion and Mountain Lion. In those cases, however, I was running earlier versions of the OSX, and downloaded the new OSX version -- Lion and Mountain Lion -- from the App Store in order to make to make the disk. In this case, however, Mavericks was pre-installed, and I was unable to download it from the App Store (an alert said that it couldn't be installed on this computer... presumably because it was already installed). I would apprecite any suggestions as to how I can create the boot disk without the ability to download Mavericks. Thanks very much for any help anyone can provide.
Shelly

Open App Store and locate the full installer download file (5.29 GBs) for 10.9.1. Download to your computer.
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.

Create CName records in your subdomains DNS servers.

I have the same problem.
Two similar discussions:
https://discussions.apple.com/message/23081658#23081658
https://discussions.apple.com/message/23281391#23281391
I have not yet seen any official response to the question: "Is the Apple AV Composite cable fully supported with 30pin connector devices upgraded with iOS7 - specifically ? - eg. iPad 2, iPhone 4, iPhone 4s"
If it is not currently supported is that then due to a bug / oversight and in that case is it something that will be fixed in the near future?
Please let us know what feedback you got from asking Apple support.

This is normal and is how Apple handles photos.
There are NOT duplicate photos.
Just as a song is in your itunes library and you can access that exact same song from a playlist, all photos synced to iphone are in the photo library and those exact same photos (NOT duplicates) can be accessed from the individual albums.
It is working exactly as it should.

I cannot connect a Sony ILCE6000 camera for wireless downloading. Sony feels I need DLNE? They do not know how to make it work. Can anyone help OS10·9·5

I cannot connect a Sony ILCE6000 camera for wireless downloading. Sony feels I need DLNE? They do not know how to make it work. Can anyone help OS10·9·5

I cannot use the software.. so you need to figure out where the problem is..
But let me suggest.. the Mac is not the issue and likely the info from Sony is also up the creek.. they make PC's after all.
It is far more likely the camera is having issues with the wireless network.
Do you know you have a connection to the home network on the camera.. ?? You have an IP address and some internet or local access at least?
How you will discover those things is by fiddling.. but if you can tell me what wireless AP you are using that will help.

I have a application build in labview 8.5 for Windows XP using NI Visa functions to interact with hardware , how to make is work in Windows 7 32 bit and Win 7 64 bit

I have a application build in Labview 8.5 which wroks fine with Windows XP , this program uses basic read /write functions of NI Visa to communicate with Hardware . This application doesnt work with Windows 7 32 bit/64 and Vista . What changes i need to do to make it work for the said operating system

You need to make sure the machine have the corresponding NI-VISA installed. Check in the NI software pages for the right version.
Also make sure that the com port's can be selected when you first start the application. Eg. if you refer to VISA "COM1" on the XP machine It might be "COM2" on the Win7 machine.

How to make MDM work?

Hi Guy,
I'm newbie for MDM.I already intalled it on my machine(Window Xp)but dunno how to make it work.
The installed components are MDM/Syndicator/Import server,Console/Import mgr/Data mgr/Syndicator.
Do I have to install any component else?And Can you guy give me any guides/documents/Posts how to make it work.Cause I have to demo it next week but right now still blank about it...
Thanks
Parinya.

Hi Jack,
For Demo Purpose,
1.Create few master records in R/3 Servers [ MM(Tcode MM01) /Employee(PA40) /Vendor(Xk01) /Customer(XD01) according to your MDM Repository(For Example "Products").]
2.Extract those master datas from R/3 Servers.
3. You will get the xml file of master datas.
4.Open the import manager and import the xml file into the MDM server.
5.In Import manager ,you need to map the records[Source Fields(Imported records) VS Destination Fields(MDM repository)].
6.Once you imported the record ,u can see the records in the MDM Data manager.
   We can Create/edit/Delete those records .
   We can merge the records for consolidation purpose.
   We can perform Data enrichments process   like Validation,Workflow,Assignments..etc.
7.Once cleaned the Master records,it is ready to distribute to R/3 servers.
8.Syndicator is used for sending data back to the R/3 servers
   Here also we have to do Mapping against R/3 servers.
   Using XI We can connect the R/3 Servers.
Hope u will understand this.
This is very simple example for MDC-MDH Scenario.
For futher learning on how to create a repository/Enrich the mater datas, go through reference documents in the Service Market place.
