Soft proofing to sRGB not working as expected

I've gone through three customer reps via chat on this, and none of them had a clue.
I recently discovered the soft proofing capability in Lightroom 4, and watched an Adobe video about it. Looked pretty cool. I experimented with soft-proofing for printing to an Epson Artisan printer. I'd always struggled a little bit with prints being too dark, etc., but now I was able to produce the best prints I've ever had.
But then I started to experiment with soft proofing for sRGB. My photo club takes photo submissions as sRGB, and they then show them on a monitor during meetings. Sometimes they don't look so good. So, I figured soft-proofing them first would help correct that.
So, I've got a photo that has a lot of red in it (a flower). The soft proofing indicated pretty much all of the reds were out of gamut. I tried reducing the saturation, but they had to go pretty much completely desaturated (black and white) before Lightroom said they were in gamut. I also experimented with change the hue, but still no luck.
I then deleted the soft proof virtual copy, and just exported the original as sRGB. Looked fine.
This would seem to make the soft proofing to sRGB to be somewhat useless for me (at least for reds - seemed okay for the small number of other photos I experimented with that didn't have that much red).
Just wondering if anyone else has had issues with this, or if I'm doing anything incorrectly, etc.
Thanks!
P.S. Update... Last chat rep had me try something that seemed to work better. My photos are stored in Lightroom as JPGs with a color space of RGB and a color profile of ProPhoto RGB. If I export that photo to JPG / sRGB, then re-import it into Lightroom, and then do the soft proofing again, it works much better. The downside of this that the two-step process makes it a bit unusable for me.

> if I'm doing anything incorrectly,
You should not really try to do the bringing of the colors into gamut too much. I know the videos you see online show this but it is really counterproductive in many cases. You'll often completely desaturate or get really disagreeable hue shifts if you trust the out of gamut warnings as you have noticed. What you should do is turn on the softproof and check whether your image looks good and the colors don't shift too much. If they do or you lose essential detail, try to correct it using the HSL tools or local desaturation. The out of gamut warning is more useful when you are proofing to a printer profile and you might have colors that your display cannot show but your printer can print. For sRGB, not so much in my experience.

That's a silly answer that rep gave you. What happens when you export to sRGB is that all your colors will get truncated hard(it uses a relative coloremtric conversion) to the sRGB profile, so if there was detail there that you wish to preserve you just lost it and you won't be able to get it back. Of course if you then soft proof the sRGB jpeg to sRGB, you will have an easy time conforming it to sRGB, since it already is! The out of gamut warning it might show you on sRGB jpegs without any correction is not correct - a known bug or strangeness with how Lightroom handles these and just tiny touches on the sliders will make them disappear. It is fooling you and in fact you were better off not even trying to soft proof and simply exporting to sRGB and ignoring soft proofing.
P.S. the monitor problems you have noticed in your photo club are probably more an issue of the monitor not being calibrated and probably not using a color managed application to show the images. If your monitor is calibrated and that one is too and using a color managed app to show the images should give you very good correspondance in color between your monitor and that one regardless of what color space you choose for the images. That might perhaps be a good thing for the club. You really need to be calibrating monitors and use only color managed apps for display.

Silverlight 5 binding on a property with logic in its setter does not work as expected when debug is attached

My problem is pretty easy to reproduce.
I created a project from scratch with a view model.
As you can see in the setter of "Age" property I have a simple logic.
public class MainViewModel : INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
private int age;
public int Age
get
return age;
set
/*Age has to be over 18* - a simple condition in the setter*/
age = value;
if(age <= 18)
age = 18;
OnPropertyChanged("Age");
public MainViewModel(int age)
this.Age = age;
private void OnPropertyChanged(string propertyName)
if (this.PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
In the MainPage.xaml
<Grid x:Name="LayoutRoot" Background="White">
<TextBox
Text="{Binding Path=Age, Mode=TwoWay}"
HorizontalAlignment="Left"
Width="100"
Height="25"/>
<TextBlock
Text="{Binding Path=Age, Mode=OneWay}"
HorizontalAlignment="Right"
Width="100"
Height="25"/>
</Grid>
And MainPage.xaml.cs I simply instantiate the view model and set it as a DataContext.
public partial class MainPage : UserControl
private MainViewModel mvm;
public MainPage()
InitializeComponent();
mvm = new MainViewModel(20);
this.DataContext = mvm;
I expect that this code will limit set the Age to 18 if the value entered in the TextBox is lower than 18.
Scenario: Insert into TextBox the value "5" and press tab (for the binding the take effect, TextBox needs to lose the focus)
Case 1: Debugger is attached =>
TextBox value will be "5" and TextBlock value will be "18" as expected. - WRONG
Case 2: Debugger is NOT attached =>
TextBox value will be "18" and TextBlock value will be "18" - CORRECT
It seems that when debugger is attached the binding does not work as expected on the object that triggered the update of the property value. This happens only if the property to which we are binding has some logic into the setter or getter.
Has something changed in SL5 and logic in setters is not allowed anymore?
Configuration:
VisualStudio 2010 SP1
SL 5 Tools 5.1.30214.0
SL5 sdk 5.0.61118.0
IE 10
Thanks!

Inputting the value and changing it straight away is relatively rare.
Very few people are now using Silverlight because it's kind of deprecated...
This is why nobody has reported this.
I certainly never noticed this problem and I have a number of live Silverlight systems out there.
Some of which are huge.
If you want a "fix":
private void OnPropertyChanged(string propertyName)
if (this.PropertyChanged != null)
//PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
Storyboard sb = new Storyboard();
sb.Duration = new Duration(new TimeSpan(0, 0, 0, 0, 100));
sb.Completed += delegate
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
sb.Begin();
The fact this works is interesting because (I think ) it means the textbox can't be updated at the point the propertychanged is raised.

Subtraction of two key figures normalized to result not working as expected

Hello SAP Community!
I am having problems with getting the right result from a subtraction of two KFs which are "normalized to results" which means the KFs really have values expressed as percentages. The substraction that should be performed is of two percentages (e.g.: 87.298% - 85.527% = 1.77%) but my report prints out the result as "number of units" instead (e.g.: 87.298% - 85.527% = 71,514.00 EA). The two normalized KFs actually "point" to two stock KFs, hence the "number of units".
In order to explain the problem I am facing please analyze below text:
1) Let's assume I have below data:
LOAD MONTH PLANT    MATERIAL HORIZON MONTH     FORECAST UNITS

2) Then, assume I have a comparison report, restricted by load month for two months May and June 2008 (filter restricted by two month variables) with FORECAST units spread accross columns for whole horizon (two months also in this case).

3) Now, let's suppose we want to know the proportions (%) of Base vs Comparison units, so
we normalize forecats to results an we get the below report:

                   Comparison Units             584,475.00 512,961.00
4) Finally, let's suppose we want to know the deltas (differences) of Base vs Comparison
units, for both number of units and %. The report now look as below:

5) PROBLEM:
In my report, the "Delta base vs. comp. units %" is not working as expected and
calculates number of units just as "Delta base vs. comp. units" does instead of calculating the % difference.
So my report looks as follows:

- Base Units %
Are RESTRICTED key figures (restricted to Base and comparison month variables) which
are setup as:
1) Calculate Result As: Summation of Rounded Values
2) Calculate Single Value as: Normalization of result
3) Calculate Along the Rows
The KFs
- Delta base vs. comp. units %
- Delta base vs. comp. units
are FORMULAS setup to:
1) Calculate Result As: Nothing defined
2) Calculate Single Value as: Nothing defined
3) Calculate Along the Rows: user default direction (grayed out)
Thanks for the time taken to read in detail all of this. Long text but necessary to understand what the problem is.
Any help is highly appreciated.
Thank you.

Hi,
The subraction will be carried out before doing the normalization of your KF's. So, it is displaying "number of units". Create a calculated keyfigure and subtract the KF's and in the properties of this calculated keyfigure, change the enhancement as "After Aggregation".
I hope this will solve your issue.

Events in SubVi not working as expected

Hi, I am reposting this question as my previous one didn't resulted in any satisfactory conclusion.
I have attached my Vi's which are not working as expected. If I remove ONE subVi and its associated 3 controls and two indicators, the other one works just fine, but when I add two SUB Vis, it goes messy. I am trying to learn this way, I am sure it can be done many other ways, but please help me finding out the problem doing it this way as in my final MainVi, I would like to use 8 such sub Vis. Thanks.
Solved!

Your main problem is DATA FLOW. A loop cannot iterate until EVERYTHING in it has completed. So, as you have it, you have to have both event structures execture before you can go back to look for the next event. So if you insist on having these subVIs, they need to be in seperate loops.
BTW, you can get away with a single subVI. Go into the VI properties and make it reentrant (preallocated clone). Then each call of your subVI will have its own memory space. A lot easier to maintain that way.
And I know you said you didn't want alternatives, but here's how you can do it all with a single event structure in your main loop.

AFS ARUN Size Substitution Not Working As Expected

Hi All,
I need help with this. If any one of you have worked with AFS ARUN size substitution, kindly provide me with some details on how can I set it up. I am specially interested in setting up size substitution with two-dimensional grids.
I have setup some examples but it does not work as expected.
Here is a small example:
Say I have a size 28/30, 28/32 .........29/30....
What I want to achieve is that during ARUN if there is a shortage of stock in 28/30 then the remaining requirement qty should be confirmed from size 28/32.
with my setup after 28/30 it goes into looking for stock in 29/30, which is what I do not want.
Any inputs will be really appreciated.
Thanks!!

Hi YOS,

Stephanie, thanks for the reply.
I am very sorry to state that I made a mistake.
VAL_SIZE_TO_IMAGE indeed works.
What fails to work is VAL_SIZE_TO_PICTURE. (Second option in Fit Mode attribute in control editing panel)
I tried with JPEG and it's the same.
I am attaching an example.(Load_Image.c & ONEP_3Trow_POS1.JPG)
A panel with two picture rings.
- SW_1 remains at the intended size and the loaded picture is not clear.
- SW_2 will fit to picture size and looks OK.
Appreciate your support,

Notification "Launch the app and go to the library" not working as expected

Hello,
we are sending notification "Launch the app and go to the library" - but it's not working as expected, it's still just launching app with last open folio.
Whats wrong there? Do we need v30 app? We have V29, but this is not mentioned in documentation.
Thanks

Ah.
Ok, now it's clear.
Anyway i would appreciate possibility to force viewer to switch to library view after new issue is detected, even without notification. Quite often requested feature - "there is new cover in Newsstand, but customer don't know how to download new publication easily".

DB Adapter polling as singleton process is not working as expected

Am using poller DB adapater to control the transaction per seconds to the downstream system and i want this poller process as singleton (One instance should be in running state at a time).
As suggested in oracle documents , below is the parameters configured in composite.xml file.
<service name="polling_Mange_Alert_Events"
ui:wsdlLocation="polling_Mange_Alert_Events.wsdl">
<interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/db/Application1/int_app_manageAlerts/polling_Mange_Alert_Events#wsdl.interface(polling_Mange_Alert_Events_ptt)"/>

Below is the JCA file parameters configured :

This poller process is running on clustered environment (2 soa nodes) and it is not working as expected as singleton process.
Please advise to solve this issue ?

Hi,
1.Set Singleton property outside   <binding.jca> like this:
<binding.jca config="polling_Mange_Alert_Events_db.jca"/>
<property name="singleton">true</property>
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>
<property name="jca.retry.interval" type="xs:int" many="false"
2.Also you can try setting these values in jca file:
<property name="RowsPerPollingInterval" value="100"/>
<property name="MaxTransactionSize" value="100"/>
3. try to increase the polling interval time.

TCP Window sizing not working as expected for Windows server 2008 R2 SP1

Hi ,
TCP window size is not working as expected. It is varying . Aplied the hotfix suggested by Microsoft and set the multipliccation factor as 1.The window size is not getting auto tuned based on the client machine. The data transfer rate is getting degraded.
Please help.
Thanks,

Hi,
I think window auto-tuning is enabled.
You can disable it by running the following commend.
netsh interface tcp set global autotuninglevel=disabled
Hope this helps.

Container-Managed Transaction Type Attributes not working as expected

I am having a problem with the container-managed transactions not working as expected. I have 2 methods that work as follows:
MethodA{
for(a lot)
call MethodB;
@Transaction Type = RequiresNew
MethodB{
EntityManager Persist to database
I want the code in MethodB to be committed to the database when methodB returns. The problem is that I am running out of memory and MethodA is failing. When methodA fails after numerous calls to MethodB nothing is persisted to the database.
It is my understanding that when using requires new transactions that a new transaction is started for each call to the method and ends when the method returns while the calling method transaction is suspended.
How am I misunderstanding the requiresNew transaction attribute. What can I do to make a batch insert into my database that will not run out of memory (commit when a methodB returns)?
Thanks in advance.

The problem is that EJB invocation semantics for security, container-managed transactions, etc.
only apply when an invocation is made through an EJB reference. In your case, you are directly
invoking the implementation method from within the bean. The EJB container has no idea that's
happening. It's no different than invoking a utility method.
In order to get the behavior you'd like, you need to retrieve a reference to your own bean and invoke
through that. You can use SessionContext.getBusinessObject() to get the EJB reference for the
business interface through which the method in question is exposed.

Namespaces not working as expected

Hi, I've got problems with namespaces not working as expected. When I isolate a process into a new network and mount namespace, a newly mounted file system will be visible to all processes.
Steps to reproduce:
$ sudo unshare -mn bash
bash# mount -t sysfs sysfs /sys
bash# exit
$ cat /proc/mounts
Result:
/proc/mounts will contain a new line for sysfs. This means the /sys/fs/cgroups directory will appear to be empty as the new sysfs is mounted over the old However you can undo it by
sudo umount /sys
Expected result:
The /sys directory will only be new inside the bash process started using unshare and not anymore once you exit bash.
Did I understand something wrong? Or might this be a bug in the kernel?
Note that when using
unshare -m bash
without isolating the network namespace it will refuse to mount sysfs as it is already mounted or busy. Strange.

Hello, because sysfs is shared, see unshare(1) for more details.

UpsertDocumentAsync not working as expected

I'm using UpsertDocumentAsync to either insert or update a document, but it doesn't seem to work as expected. When I use it either inserts / creates or
replaces the document. I doubt I'm calling it wrong?
await client.UpsertDocumentAsync(documentsLink, this.document);
Working as expected (but with incorrect name) or not working as expected?

Voted for that one, but it doesn't seem like the developer community is interested in upsert/patch functionality =/.

Keyboard not working as expected

I woke up this morning and suddenly found a few problems with my keyboard:
The caps lock light is reversed so that the caps is off when the light is on and vice versa
The placement of some of the symbols are moved around. The @ is to the right of the P button and Shift-2 produces a ". Shift-9 is ), shift-8 is ( and many other switched like this.
Resetting PRAM or the computer doesnt fix this

Hello there, morris152.
The following Knowlede Base article provides some great information for troubleshooting your issue with the keyboard:
One or more keys on the keyboard do not respond
http://support.apple.com/kb/ts1381
Particularly:
Some keys don't work as expected
From the Apple menu, choose System Preferences.
From the View menu, choose Speech.
Click the Text to Speech tab.
If "Speak selected text when the key is pressed" is enabled, the key or key combination set to speak text cannot be used for other purposes or used to type text--click Set Key and change it to a less-commonly used key combination (try to use modifier keys such as Shift, Command, Option, and Control). Or, disable the "Speak selected text when the key is pressed" option.
Click the Accessibilty or Universal Access pane in System Preferences, then click the Keyboard tab.
Make sure that Slow Keys is turned off. With Slow Keys on, you need to press a key for a longer period of time for it to be recognized.
In the Accessibilty or Universal Access pane, click the Mouse tab, and make sure Mouse Keys is turned off. With Mouse Keys enabled, you cannot use the Numeric Keypad to enter numbers--instead the keypad moves the pointer (cursor). (There is an option to enable Mouse Keys with five presses of the Option key; you may want to turn that option off to avoid accidentally enabling it.) If Mouse Keys is enabled and you are using a keyboard with no numeric keypad or Num Lock function, see Unable to type while Mouse Keys is enabled in Mac OS X.
If the function keys on the top row of the keyboard are not working as expected, see Mac OS X: How to change the behavior of function keys.
If the issue persists, use Keyboard Viewer to help isolate the issue:
Click the Language & Text pane (Mac OS X v10.6) or International pane (Mac OS X v10.5.8 or earlier) in System Preferences.
Click the Input Sources tab (or Input Menu tab in Mac OS X 10.5.8 or earlier).
Click the Keyboard & Character Viewer "On" checkbox to select it (click the Keyboard Viewer "On" checkbox in Mac OS X 10.5.8 or earlier).
From the Input (flag) menu, choose Show Keyboard Viewer.
If the keyboard is connected and detected by OS X, the keys you type will highlight in the Keyboard Viewer window. Open TextEdit (or any text application), and try to type something using the keys that were previously not responding to see if they highlight in Keyboard Viewer.
Start from the Mac OS X Install Disc, choose Terminal from the Utilities menu and test the keys which were previously not working. If the keys work while started from the Install disc, then the keyboard itself is working correctly. Use How to troubleshoot a software issue to isolate the software issue that may be causing the keys to not respond.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Read Key and Write Key not working as expected with paths on RT

The configuration file VIs Read Key (Path) and Write Key (Path) don't seem to work as expected (at least not as I was expecting them to) on an RT target.
When working on my WinXP PC with these two VIs, paths are translated to what looks like is supposed to be a device-independent format before being written to disk. The path C:\dir\file.txt becomes /C/dir/file.txt when writing and vice versa when reading. On my RT target, however, that same path is written to disk as C:\dir\file.txt, unchanged from the native format.
The translaton of a native path to and from the device-independent format appears to be the responsibility of Specific Path to Common Path and Common Path to Specific Path. These both use the App.TargetOS property to determine the operating system. In the case structure for these two VIs, however, there is no case for PharLap or RTX. (My RT hardware is runnng PharLap; I don't know enough about RTX to comment.) This means that the results of String to Path or Path to String are used without translating between the device-independent format to the native path format.
This isn't a problem if you create a configuration file on one machine and use it on that same machine. I noticed this only when tranferring a config file from my PC to the RT target, where the target would not open the file paths it loaded from the configuration file.
This occurs on 7.1.1 and 8.0. I don't have 8.20 to see if happens there, too.

In LV 8.2, this was fixed.
The problem is App.TargetOS returns "Pharlap" on RT systems, and "Pharlap" is handled by the default case ("invalid OS target") in LV 8.0. In LV 8.2 the default case is "Windows 95/NT", however. The reason you could write and read an .ini file on RT in LV 8.0 and earlier is because these two VIs (listed below) were both running the default case of "invalid OS target".
vi.lib\Utility\config.llb\Common Path to Specific Path.vi
vi.lib\Utility\config.llb\Specific Path to Common Path.vi
As you saw, this fails when you perform one operation in Pharlap but the other in Windows. You can fix this by modifying the two VIs listed above. Just go to the case structure and make "Windows 95/NT" the default case.

Windows - Use system proxy settings not working as expected

Hi everyone,
I have a bit of an issue that I could use some help with. We currently have remote users that utilize an SSTP VPN connection to access our internal network. Once connected, those users are required to use an internal proxy server to connect to the Internet. The proxy server is Microsoft's TMG and utilized domain authentication.
On our remote Windows clients we have their Internet Options configured to utilize a proxy as follows:
Internet Options -> Connections -> LAN Settings -> No proxy configured at all
Internet Options -> Connections -> Highlight SSTP Connection -> Settings
Use a proxy server for this connection -> IP/Port of Proxy Server
Firefox and Chrome are both configured to use system proxy settings.
Here is my process to demonstrate the issues:
Remote client workstation is rebooted.
With the above configuration just after a reboot, a remote user that is not connected to the VPN can browse the Internet with Internet Explorer, Chrome, and Firefox. None of the browsers prompt for credentials.
A remote VPN connection is then established.
FF is opened and HTTP connections utilize the proxy server. However, HTTPS connections do not use the proxy server, but instead attempt to use the default gateway. FF does not prompt for credentials. FF is closed.
Chrome is opened and can access both HTTP and HTTPS sites without issue. No credential prompt. Chrome is closed.
IE is opened and can access both HTTP and HTTPS sites without issue. No credential prompt. IE is closed.
Here's where it gets weirder...
FF is then reopened. The VPN connection is still up. FF will prompt for credentials. Domain credentials are supplied and FF can now utilize the proxy for both HTTP and HTTPS connections. FF is closed.
VPN is disconnected.
FF is opened and cannot access the Internet as it is still trying to use the proxy server. FF is closed.
IE is opened and can access the Internet. IE is closed.
Chrome is opened and can access the Internet. Chrome is closed.
FF is reopened and can now access the Internet. FF is closed.
In summary, in the above scenario FF acts in an unexpected manner with regards to proxy usage when "use system proxy settings" is applied. However, Firefox begins acting as expected after IE is opened and closed. For example, connect to VPN, open IE, close IE, open FF, and everything works accordingly. Disconnect the VPN, open IE, close IE, open FF and everything works as expected.
Any insight you can provide would be appreciated as it is affecting our FF users and the sooner we can achieve resolution the better. As a note, we've also worked through this issue with WPAD and proxy auto-detect. I've intentionally removed these from the equation to simplify troubleshooting.
Thanks

Quick update. Added to a previously filed bug. Looks like it's assigned now so maybe we'll see a fix for this soon.
