[Feature Request] Seperate tab in log window for System.err

By default, the stack traces of exceptions (and throwables in general) are printed to the System.err stream. So, wouldn't it be useful to include a 2nd tab for System.err messages?
It could be optional to either include or leave out the System.err output in the System.out tab.
The whole idea of this 2nd tab is to set it up like the search output tab: a tree-like list which can be expanded to see the stack trace of each exception that occured during runtime. A small parser can parse the stack trace when an exception is printed on the System.err stream and format it.
If this option would be availble in the debugger only, that would be ok too, I guess. Although, the debugger already has some other means of jumping through code when an exception is thrown (ie, when the debugger 'pauses' runtime).

I've logged an Enhancement request to improve the handling of System.err messages (2811508). There are ways to enhance the treatment of System.err messages without introducing a new tab, through the use of color, links back to the source code, and collapsing of entire stack traces to a single line (with a button to see the entire trace).
Thanks!

  • [Bug: JDeveloper 9.0.3] Context menu on active tab of Log window

    When I right-click on one of many tabs in the log window to open the context menu, and when for some reason another tab becomes active, the context menu now targets the active tab, instead of the original one.
    Say, I ran a project and want to clear the respective tab, so I right-click on the tab to open the context menu. But before I can click on 'Clear', some other running project generates output on its tab, so that other tab becomes active. Now, when I click on 'Clear' anyway, the newly activated tab will be cleared, in stead of the tab I intended to clear.
    I don't suppose this one's is a biggy, but I'd like to report it anyway.

    Ow by the way, of course this is a bit of a bigger issue when you select 'close'. ;)

  • Feature Request: more info in 'Reply' window

    Perhaps this has been requested before but I haven't seen it so please forgive what may be rehashing an old request.
    One thing I find inconvenient about responding to some Discussions posts is that in the "Post Message: Reply" page the user profile info about their Mac model, OS version, & other computer information is not displayed along with the text of their message. Since sometimes this info is critical to posting an appropriate reply, it would be useful to see it while composing a reply, just like it is in the threaded views of the topic's posts.

    Of course tabs in one window will all close if the the window is closed (the red close button vs the (x) in the tab).
    With a lot of tabs present in one Safari window, the tab names become highly truncated. Because of that it is too easy for me to accidentally close a tab by clicking on its "x" when I meant to click on its name, & too easy to lose track of which tab is which.
    It probably is less of a problem with a large screen, but on a 13" MacBook it can be quite annoying, particularly if I'm trying to leave some screen space available for referencing the contents of other windows besides Safari's for some Discussions reply.

  • Bizzare error message requests me "Select a log file" for .vi

    Hi
    I am getting a very strange pop-up with my vi that requests me to select a log file for the VI.
    If I hit cancel I get the pop-up "Cannot log front panel of vi. there is no log file associated with the vi"
    I don't want a log file. 
    There must be some background setting in the VI that is not in the actually Lab-VIEW code.
    Does anybody know how I can switch this off?
    Many thanks
    Ashley

    Off the top of my head I can only think of one setting that may cause this.  You can set a VI to log its front panel data automatically.  Go to Operate>>Data Logging and check the settings there.    Also look at Operate>>Log at Completion.
    It may also be that you have this set on a subVI, and if so you will see a yellow "halo" around one of your subVIs, meaning you have turned on database access.  You can look in the help for Logging Data>> On the front panel that discusses this behavior.
    If you wrote the VIs and have no idea what I am talking about with the Database Access that is fine, it is not a commonly used feature.
    If none of these help can you attach the VI so we can all see it.

  • How to close a popup window for system events?

    Hi,
    I have a screen 110 which shows several input field in popup mode.
    The Cancel button can close the screen.
    But my question is how to close the popup window for the following system events?
    1, Customer clicks the cross button in top-right corner
    2, Customer clicks the system icon in top-left corner and then select either: "Close" or "Stop Session"
    The PAI subroutine of the screen has not been triggered for the above system events.
    Thanks for the coming help.
    Best Regards,
    David

    Hi Siddharth,
    I did check with another very experienced ABAP developer.
    The solution was the same as what Arunima Rudra provided.
    And I got a sample program which did work properly.
    The headache is that the system events in my program still cannot be triggered even after I have all the same changes.
    Anyway, I suggest you to try the solution as provided by Arunima Rudra.
    It should work for 2 system events:
    1, Customer clicks the cross button in top-right corner
    2, Customer clicks the system icon in top-left corner and then select either: "Close"
    For "Stop Session", it should not be handled by popup.
    You can observe the same behavior in ALV sorting configuration popup.
    Good luck!
    Regards,
    David

  • Which log file contains System.err output?

    If I start weblogic using startWebLogic.cmd then output sent to System.err gets
    output to the console window that opens up. However, if I instead start weblogic
    as a service, nothing sent to System.err gets output to the weblogic.log file.
    Where does it go?

    Hi there,
    My message was borne of 2 days frustration out of nearly a year of smooth operations with Oracle App Server. Unfortunately I let my mouth (or fingers) run off with those frustrations and made a post that was innappropriate and un-necessary and like every bad workman I blamed my tools.
    My apologies for that. Having found where the OPMN logs are stored (and it's pretty obvious to anyone who isn't seeing through a red mist!) I have now fixed my issue pretty quickly.
    Thanks for your patience glin - OAS and JDev together have in this past year have served me well and as you say are in general pretty straight forward to use. (My frustration was due to J2EE ClassLoaders, they always cause me some kind of headache somewhere!)
    Best Regards,
    Happy Holidays!

  • [Feature Request] 'Duplicate Tab' in Tab Dropdown

    I know now that you can duplicate a tab by Control-clicking or middle-mouse-buttoning the Reload button, or by Control-dragging the tab over. But what would have been most intuitive is if there were an option to do this in the tab dropdown. I'm more of a person to do things long-hand, and I imagine many others are, too. Just want Firefox to be great.
    Thank you!
    Sincerely,

  • Feature Request: user-defined virtual keyboard popup for text fields

    It would be convenient to be able to define (either declaratively in XML or programmatically) custom virtual keyboards (codepoints + font-name)  that could be popped up from the context-menu on any text field.
    The string of characters produced on the virtual keyboard should be inserted into the associated text field at the .selectionBeginIndex location, or replace any selected text, if applicable.
    Adobe could also supply  predefined keyboards, but the important thing is that the programmer have the ability to define custom layouts and choose which codepoints the virtual keyboard contains, and that it be launchablefrom a custom contextmenuitem or that it be very simple and easy to tell Adobe which layout should be launched shoulda default contextmenuitem be dedicated to this purpose.
    Slick if it could support programmer-controlled transparency, so what lies beneath it could be revealed if the programmer desired.

    User-controlled transparency (with a slider) would also be a nice feature, though the programmer should be able to hide/show the slider widget.

  • Feature request: Add left-handed users support for Show Pointer

    Show Pointer is a very useful tool for precise movements and operations on the touch display.
    However, the way it currently works is optimized for right-handed people (as the button is on the left side and you maneuver with the right hand.
    As there are very many left-handed people among creative individuals, I'm kindly asking to add left-hand support to Show Pointer, which would effectively mirror the user interface of the tool (button on the right side).
    This could be configured in the Photoshop Touch setting panel.
    I would really appreciate someone from Adobe reading this and adding this to the product backlog. Thanks.

    If I'm ever asked to give input, I'll be sure to +1 for you. 

  • FEATURE REQUESTS: Border Panel and Transparency slider for bg color

    Some points:
    1) "Color" by itself is a dubious panel name. Color of what? Please use the existing CSS property names wherever possible, and separate out background color and border color.
    2) Transparency sliders need to be enabled for all color pickers everywhere in the UI. RGBA everywhere, always. No hex colors, ever, please. There's just no reason anymore.
    2) Border sides need to be separately tweenable in the UI. I've posted about this before. Here's a bit more detail:  Use a 1-to-4 toggle button at the top of the Borders Panel to go back and forth between a simplified and a four-separate-borders interface. Something similar to what you've done in the Corners Panel. I've mocked up the panel UI below.
    4) Hire me as junior interface designer on this program.

    @Sarah:
    You're right about selecting opacity in the color picker. That's probably cleaner. But it doesn't bother me in the slightest that a border with an alpha is rendered over the background-color. That's CSS. (Just use a bg color of "none" if that's what you need.)
    In response:
    1) Please don't use CSS "outline" for any heavy lifting in Edge. The interoperability problems are currently massive. For one thing, Firefox draws outlines outside of any box-shadow, contrary to the spec. This bug has festered for three years now, and shows no sign of ever being fixed:
    https://bugzilla.mozilla.org/show_bug.cgi?id=480888
    The other big limitation is that outline edges are always square, and can't be rounded. To create what you're calling an "external" border just use a box shadow with no blur. This is a standard practice, and renders well. Whatever you do, please don't make a panel called "borders" that actually creates box-shadows. The answer is education and evangelism, not mislabelling things.
    2) Borders don't change the external dimensions of an element if you use border-box globally. Positioning doesn't get the least bit "out of whack." There shouldn't be any trepidation there. This is probably how Edge should work across the board, for all elements, especially if the math of box-sizing is getting you and your engineering team down For folks who aren't hip to this yet, see this fiddle:
    http://jsfiddle.net/tUVM7/
    and this explanation of the property:
    http://paulirish.com/2012/box-sizing-border-box-ftw/
    Borders and Box-shadow panels need to be in the "frontlog", not the backlog.

  • Feature Request: Raw-Lite for the F5/F55

    Hi Sony Staff, Here's a feature request that I've been pondering for a long time now. Raw Lite on the F5(5). Is it a possibility? I'm a huge fan of the conventional 3:1 compressed 4K 16-bit Linear Raw from the AXS-R5. It provides a supremely high quality digital negative, with as much detail and tonality as you could ever really need. However the file sizes are very large. 1TB yeilds roughly an hour of recording time. And the storage costs associated with that are enough to scare away MANY producers from shooting Sony Raw (even with all of the benefits that doing so offers).  You guys have addressed this issue nicely with the F65 by offering Raw Lite with it's 6:1 compression (which coincidentally, is a compression rate that many, many producers are content to shoot with on the most prolific raw cameras out their - the Red Epic/Dragon/Scarlet cameras). Being able to offer producers the option to shoot Sony Raw Lite, with it's massively more managable file sizes would greatly increase the uptake of Sony Raw for production - and that benefits everyone. It benefits the camera department with a superior digital negative, it benefits post-production with greater latitude for grading and VFX, it benefits producers with a superior end product, and it benefits audiences with better looking images. Given that the F65 was able to be upgraded to offer this additional raw recording option, I assume (and hope) that it's not an impossiblity for the F5(5). So I'd urge you to strongly consider this feature request, and the added appeal it would bring to the cameras as a capture choice. Cheers, Mark

    I disagree that there is little difference between 12bit and 16 bit linear raw. The difference is huge. Shadows and dark areas from the FS7/FS700 are pretty grim, lot's of noise caused by the data rounding. Besides, in terms of bit rate it's not a question of simply reducing the bit depth, you need to increase the compression. For linear raw you need 16 bits unless you do an extreme amount of data rounding. For Linear raw, if the first stop is represented by just 2 bits of data (which results in very blocky noise as noise will be one of 4 luma levels and cannot be smoothly reproduced):  stop 1: 2 bitsstop 2: 4stop 3: 8stop 4: 16stop 5: 32stop 6: 64stop 7 128 (8 bit linear limit, 128 + 128 = 256 bits)stop 8: 256stop 9: 512 (10 bit linear limit)stop 10: 1024stop 11: 2048 (12 bit linear limit)stop 12: 4096stop 13: 8192 stop 14: 16384 bitsstop 15: 32768 bits (16 bit linear limit) If you move this scale up so that the first stop is represented by using 4 bits of data you will still have pretty coarse shadows and noise (one whole f stop will only have 16 posible luma values). So rather than just use binary math most linear raw systems use floating point math to make more bits available for the shadows. But with 12bit there just isn't anywhere near the same amount of "spare" bits that you get with 16 bit, so the shadows and low key areas really suffer. Just go and look at the FS7/FS700 boards and all the compliants about unusable, grainy and blocky shadow areas in the raw. Sure raw lite would be a welcome option, but it wouldn't be one for me. The whole point of raw for me is a robust, bomb proof format that you can expose and grade as you wish without worrying about artefacts etc.
