Minor bug with Connections node in SQL Dev. 2.1 EA1

This is minor compared to some of the other issues found with EA1.
When I expand the Connections node by clicking on the "+" I cannot collapse it when clicking on the "-". This happens both when migrating settings from 1.5.5 and when starting clean without migrating settings and then creating new connections. (I deleted the "system2.1.0.62.61" folder between tests.) I tried this by running "+<install_dir>+\sqldeveloper\sqldeveloper.exe" and "+<install_dir>+\sqldeveloper\sqldeveloper\bin\sqldeveloper.exe" to get a console window. (The only messages I saw in the console window occurred when I opened a connection.)
Here are the "About" and "Version" info:

Thanks the bug is that the +/- is even being shown. I put something in there to prevent the collapsing of that since there's nothing when it's collapse.

  • Weird bug with desynced nodes - including demo and screencast

    This is a follow-up to Desync of Elements and logic - how to debug?
    I started a new thread because I will provide better information on this.
    So we've made our graph editor working with JavaFX. One of our common demos for different products is a organizational chart demo. This is a tree-like graph with employees as nodes to depict the hierarchical structure of companies.
    You can try this demo here (jre7u6 with JavaFX 2.2 b17 required):
    http://www.yworks.com/products/yfilesfx/OrgChartDemo/OrgChartDemo.jnlp
    We have also made a screencast which can be viewed here that shows the usage and most importantly the problem we are facing with JavaFX here:
    http://www.screenr.com/uEF8
    The startup is quite slow, it takes a few seconds for the graph to load. This is because the visual representation of the nodes is described within (nested) fxml files and each of those files is loaded in a not so effective way (because it is at the moment not possible in JavaFX to define a custom BeanAdapter in the FXMLLoader that does proper caching). After those files are loaded, there are still some ClassNotFoundExceptions thrown in the background by some part of the JavaFX framework I did not identify, yet. After a few seconds the performance speeds up significantly.
    What you can do in this demo is described on the right. Basically you can zoom in/out, fit view, center a certain employee and interact with them.
    Interaction means you can collapse and enlarge certain parts of the graph. For example, you can hide all subordinates of an employee and show them again.
    The part of "showing them again" is done with an animation effect that is implemented in our framework, not in JavaFX.
    When you hover an employee, a fading translation is played as a hover effect and some buttons appear. This part is important so i wanted to highlighted.
    The hover effect is triggered by a onMouseEntered and onMouseExited event.
    Also you can focus a certain employee by clicking on them. When clicked, the color changes from blue to orange. This is done by our internal logic, since the clickable things on the screen are not the JavaFX rectangles and such but rather a logical representation of a node with a position on the screen and a with and height.
    So this is where things go wrong and what is really crucial for our application:
    When you collapse/enlarge nodes (employees) a bug appears quite frequently that causes the internal representation and the actual appearence of JavaFX elements on the screen to be out of sync. Most notably the hover effect doesn't work anymore: The node is visually present (as you can see it) and the values of the nodes in the scenegraph match as well, but those nodes just are not present any more for any events. They do not receive mouse entered/exited events, hover-events and pressed-events and so on. You can still click on the node and focus it, but this is done in our framework (indicating that our logic works).
    The connection of the logic and the javafx controller is done via databinding. The controller listens to changes in the corresponding model item and updates itself accordingly - you can see it when clicking on a node, the selection state of the model item changes and the controller updates the style of the javafx node.
    The other effects however, like the hover-effect, are implemented on databinding on properties of the JavaFX node class: hoverProperty, onMouseEntered onMouseExited and so on.
    Once a node is in this state, weird stuff is happening. For example, a node that is in this state seems to have normal values when viewed in ScenicView. However, when changing some values, for example translateX / Y, the node just disappears. (see also: http://www.screenr.com/lYF8 where i recorded that (a bit later in the video))
    For an example of this have a look at the link to the screencast above. We showed how to reproduce the bug there.
    We noticed that without any animation played this does not happen. So it seems to be caused by the animation. This is itself quite surprising, because we used the same animation process with other javaFX applications but never experienced this bug.
    What happens is that our Animator sets the layoutX and layoutY values of a node that is being animated repeatedly and in rapid succession over a period of time.
    The only thing we can think of that might cause this problem is that JavaFX somehow is not able to process a large amount of such update-calls and throws some exception internally and just dies.
    Because of this we strongly hope that somebody can point us to were we have to look or how to even debug this problem.
    * edit: added second screencast for ScenicView

    I use the swing version embedded in Idea and the diagrams are really nice => everytime I make a printout I get asked "what tool did you use to generate that diagram?".:D thank you very much.
    Only real advice I can offer is something you almost certainly know =>
    JavaFX is a singlethreaded UI framework.
    Ensure that anything you do which could read/write from nodes in an active scenegraph be done on the JavaFX application thread.I just double checked this and unless Platform.isFxApplicationThread() returns a wrong value, the only interaction with JavaFX nodes is done in the JavaFX application thread.
    I think your app issues will prove very hard to resolve through this forum. Nicolas Lorain is the javafx product manager, so you could try contacting him directly for support. There is also some kind of JavaFX partner program which may be able to offer support as well, Nicolas should also have details on that.
    Good luck with your app.I just searched for the JavaFX partner program, and couldn't find anything ongoing. The only advanced support I could find is the Oracle Premier Support, which at this point isn't suitable for us. I also couldn't find any contact information for Nicolas Lorain (he has a blog and twitter but I cannot find his email). So if you could point me to somewhere, I'd be very glad.

  • Bug with readonly view (through sql query)

    HI , I'm using JDEV11.1.1.2
    I found the following problem which I consider a bug:
    When you create a readonly view object based on sql query the first attribute gets type: VARCHAR2(255) although it is VARCHAR2(10) in the database. All other attributes get the correct type and length only the first one is not correct.
    Can you confirm this behavior to be a bug ?
    Thanks

    Hi,
    of other string attributes show the correct length then this indeed sounds like a bug. However, a bug is a bug when it is getting filed.

  • A minor bug with Application Bulider menu in 2.2.1

    I have two apex instances which are used primarily for development and periodicaly synchronized via application exports. After some time of such activity I lost my application in the application builder menu on the first instance (still have access to the application by clicking Application Builder icon and choosing from the application list). On the second instance I lost section with Export, Import submenus inside this menu. Now just see two separators sticked together without these items between them.

    Edward,
    I lost my application in the application builder menuI'm not exactly sure what you mean. If you mean the history of the most recently edited applications that you see at the bottom of the Application Builder drop-down list (zero to four application IDs and names), this history will be nullified for applications that you import as the import action clears the audit trail.
    About the Export menus, I don't know what you mean, maybe you could post a screenshot.

  • NI DC Soft Front Panel, minorbug, minor bug with PXI-4110

    Hi
    The NI DC Soft Front Panel V14.0, with the PXI-4110, the negative voltage scroll, works as expected to -10V, but then rolls over to 0. If one changes in -1V steps, it goes.... -8, -9, -10, -1, -2 ..... instead of -8, -9, -10, -11, -12 ...
    While at it, a simple thing I miss is a on/off button for all three voltages.
    (Also, imo, it would be logical to get negative voltages with the down arrow, not up).
    My 2C
    Solved!
    Go to Solution.

    Hello Janaf,
    I fully agree with both of your statements, I have filed a Correction Action Report which you can monitor in next releases of DCPower to see if this is fixed with the SFP. Number of CAR: 512257
    I added notes that only manual insertion of numbers less than -10 works and that it was not logical to use increment arrow or up arrow to decrease the voltage output.

  • Minor bug with editing when there are multiple pages of reports on the list

    When I edit a report and save the changes, I am returned to a different page on the list of reports than I started from.
    Steps to reproduce:
    1. Sort reports by Type
    2. On the first page on the list of reports, find  a custom report I created
    3. click Edit, then click Save
    4. I am returned to page 2 of the reports instead of page 1.
    5. If I click Cancel instead of Save, I'm returned to page 1 as expected.
    Depending on which page I started from I may be returned to some other seemingly random page, i.e. starting from page 4 I might be returned to page 3.
    Expected behavior - it should either return me to the first page, or else return me to the page I started from.

  • 100% cpu utilisation SQL Dev 1.5 on XP

    Using SQL Dev 1.5 prod version on XP on a P4 3ghz with 2gb of ram, SQL Dev executable regularly uses 100% cpu utilisation as reported by task manager.
    Also frequently stops responding - no screen redraw and I have to end task.
    Until recently I only had 512Mb of ram so put this down to that fact, but with 2gb still getting long 'satellite' delays - particularly with code/param insight.
    Anybody else getting this?
    ta

    I know I was vahue - apologies, but it's most of the time - literally 99 to 100% cpu utilisation.
    e.g.
    restart pc, login, give it a couple of mins to settle down. (p4 3ghz, 3gb ram, xp pro, sp1)
    start 1.5 sqldev - wait, see the splash screen, look at task manager - memory starts going up, cpu rises rapidly to 99 - 100%
    once fully loaded, open 1 connection, open one package body, split screen vertically, so I have sql worksheet and my package body open and visible.
    Now sit back and enjoy the vibration coming thru the desktop - the real wooden one - as the pc's fan struggles to cope.
    If I leave it for maybe 5 to 10 mins - not doing anything on the pc at all, cpu utilisation will drop significantly.
    then do something reckless like edit my package body (not that big ~1500 lines) and hold on to the desk again as we start shaking once more.
    great for my typing skills too, as there is no point in looking at the screen to see if I am making mistakes, as it frequently won't display anything until 3 to 5 seconds after I have finished typing
    mem usage is up to 250 mb - I have not touched my pc for nearly 10 mins since doing the last edit - still at 99%

  • Cluster VI Reference Minor Bug

    Over on LAVA PJM_labview posted a video of a bug found in LabVIEW 2013 SP1.  It is a minor bug with the block diagram when showing a cluster constant with a VI reference constant in it.  Here is the video of how to reproduce the bug.

    If 10 out of 10 experts in any field say something is bad, you should probably take their opinion seriously.

    I played with this and filed it as a CAR (#479432). Intriguingly, there are a couple workarounds:
    Option 1
    On block diagram:
    1. Create cluster constant containing refnum with auto-sizing set as arranged (vertical or horizontal)
    2. Create typedef
    3. Unlink from type def
    4. Change auto-sizing to desired value
    5. Recreate typedef
    Option 2
    On front panel:
    1. Create cluster containing refnum control
    2. Create typedef
    On block diagram:
    3. Create constant from cluster typedef on block diagram.
    4. Unlink constant from typedef, change auto-sizing as desired, recreate typedef

  • How to use SQL Dev with MySQL DBs ? Connection Setup

    As far as I know SQL Dev can be used with MySQL databases as well.
    How do I have to setup the connection for MySQL?
    In detail what do I have to enter for
    -role
    -connection type
    SID/ServiceName
    Or is there a separate version for Oracle and MySQLß
    Peter
    Edited by: user5328442 on Jan 5, 2011 9:23 AM

    Hi,
    After downloading the MySQL plugin did you add the details in the third party database list ?
    Do the following -
    - Tools
    - Preferences
    - expand the Database option if necessary
    - Third Party JDBC Drivers
    - add the location and file name of the plugin.
    On my setup it is -
    D:\mysql_jdbc\mysql-connector-java-5.0.8\mysql-connector-java-5.0.8-bin.jar
    The driver may be different if you have a later version.

  • EA1: Is SQL Dev 2.1 able to talk to a DB with no listener?  1.5.5 could.

    We use local installs for each developer, the locally installed DB runs with no listener. TOAD, SQL Dev 1.5.5 and SQL*pluss all had no issues talking to my local install. With 1.5.5, I simply left the connection type as BASIC with a blank hostname and port. Similarly with TOAD and with SQLplus, I left all details (except the user and password) blank, and they connected ok.
    2.1 is unable to connect, it tells me that I can't leave the hostname blank, and that the port number is invalid.
    I've tried exporting the connections from 1.5.5 and importing them. All other connections ( to the team dev, the CI, the build, the test, QA and production environments) work with no issue. Connecting to my local db with the imported connection gives the error:
    no ocijdbc11 in java.library.path
    Vendor code 0
    So how do I use this version to talk to a local install, that is not running a listener?
    Please don't respond if all you can say is "run a listener" :)
    Local DB is 10gr2, using the latest patches, with the latest 10gr2 client

    Edited by: user1357095 on 01-Nov-2009 22:04

    The ocijdbc11 error would indicate it's prioritizing your 10g client. You can try tricking sqldev by changing your ORACLE_HOME within a batch file inside sqldev's install folder. This would force using the supplied thin 11g driver:
    set ORACLE_HOME=%CD%
    start sqldeveloper.exeHope that helps,

  • Cancelling Query Results in Continually Busy Connection -- SQL Dev 2.1 EA2

    Hello All --
    I am running SQL Developer 2.1 EA2 on the Windows 7 Release Candidate (64-bit). I have had issues when canceling long-running queries. Usually what happens is I run something, and realize after a couple of minutes that it's going to take quite a while to run. So, I click the cancel button. Things seem OK, I can resume editing the query. However, when I try to re-run the query (after modifying it) or even just to run an explain plan, I find that I can't re-connect to the DB. I go to the connection pane to try to disconnect and reconnect to the server in question, but when I try to disconnect I keep getting error messages about the connection still being busy, would I like to Retry or Abort? I can keep clicking either of the options ad infinitum with no results.
    I have to kill SQL Developer from Task Manager and re-start. I am connecting for the most part to Oracle 10.2.0.4 databases (10g2), some RAC, some stand-alone.
    EA2's behavior is better than SQL DEV 1.5.x, which would simply often lock, but this is still frustrating.
    Thanks!

    This definitely occurs in 1.5.5 - in my particular case, and this is really strange, if one uses Task Manager to shut down SQLDeveloper because it is just taking forever to get a Data view (via the + expand sign on the side of a given admittedly big table, then clicking on the Data tab), SQLDeveloper freezes. Even if I start a new instance of SQLDeveloper, and ask for a Data view again, it freezes - I've waited as much as 1/2 hour, where as in prior days I'd get a response within say 1 min.
    I've even uninstalled and re-installed. Same deal. This is what's the strangest by far. How can it be that SQLDeveloper remembers that a long running query was once canceled even after an uninstall / reinstall ? I could not find anything remotely related to this in the Registry after the uninstall either.
    [By the way, if on the other hand, I say SELECT * FROM {table_name}, I get an instant response !]

  • I can compile objects with SQL dev tool but not with a direct sql

    hi,
    This is a bit weird - I'm probably not familiar enough with Oracle's compilation process...
    I'm creating a some functions / procedures / triggers. When I run the script to create them with Oracle's SQL Developer tool, usually they become immediately valid, and if not then I can manually right click them and choose Compile, and they're compiled correctly and become valid.
    However, when running them with command line tools, they're uncompiled after created. I'm trying compile them with
    ALTER PROCEDURE / FUNCTION / TRIGGER MySchema.MyFunction COMPILE;
    and it always returns
    Error starting at line 1 in command:
    alter function MySchema.MyFunction compile
    Error report:
    SQL Command: alter function
    Failed: Warning: execution completed with warning
    alter function MySchema.MyFunction succeeded.
    and the object remains uncompiled / invalid.
    also tried with DBMS_... utils and got the same results.
    Same with adding things such as PLSQL_WARNINGS = 'ERROR:ALL' to the stmt
    But when I go in SQL Developer to the object, right click and click Compile, it compiles fine w/o warnings / errors and becomes valid.
    Is there anything else I should run other than this alter..compile? Is SQL Dev tool doing something different than "alter function ... compile" when right clicking and object and clicking "Compile"?
    thanks!

    hi,
    I'm having difficulties connecting with SQL Plus, since it seem to require at startup some admin user/password, which I don't have at the moment. Also tried to give it in command line the db name and params and it still require this pass... Will try to get it...
    But again, when I'm right clicking the object in SQL Developer and click Compile, it compiles fine and becomes valid. After doing that, running
    alter function mySchema.MyTestFunction compile;
    passes with
    "alter function mySchema.testfunction succeeded"
    If I run this sql before doing compile with SQL Developer, it fails with what I posted before.
    I wonder if SQL Developer does things other than the above compile stmt.
    If I right click on Functions in SQL Dev and click Compile All or Compile Invalid, I can see the sql it about to generate, and it's the same as I tried - and fails as well... Only when right clicking the object and Compile it works...
    A test func I tried, for example:
    create or replace
    FUNCTION testFunction(n in number)
    RETURN NUMBER
    IS
    BEGIN
    RETURN n + 1;
    END;
