Strange behaviour with combo boxes.

Has anyone else noticed strange behaviour of combo boxes with applets?
What happens is that on selecting the combo drop down, the dialogue the combo is sitting on moves behind its parent window. You just end up seeing the combo list, and no dialogue. Select a combo item, and sometimes the dialogue reappears, and sometimes it is still hidden.
I've only seen this whilst running an applet in browsers. In Eclipse I don't see the behaviour.
The behaviour is also very intermittent.
I'm using Java Plug-in 1.6.0_10-rc2, Using JRE version 1.6.0_10-rc2 Java HotSpot(TM) Client VM, on Windows Vista, Google Chrome browser.
I'd raise it as a bug, it certainly seems quite serious, but I don't have a reliable test case.
I have a work around, on all my dialogues with combo's on them, I have setAlwaysOnTop(true). Not really the correct behaviour though.

  • Strange behaviour with Safari.

    Very strange behaviour with Safari this morning.   Pages loading piecemeal or partially.   The content only becomes viewable after the cursor has passed over the area.   Have cleared caches and reported it but I'm wondering if this is a local matter here in the UK.   Anyone suffering similar problems?    Firefox is responding perfectly normally.

    I see a reply has come back via a previous post.   As I am trying to get a response to this one I shan't reply there but I should point out that for me, this is an isolated problem.   I do use open DNS but with no track history of problems there , I can't blame that.
    In the last few minutes normality has returned.

  • Strange behaviour with nested overflow headers

    Hi there,
    I have a strange behaviour with nested overflow headers. I have a hierarchy with some dynamic tables an several headers for the hierarchy steps. When the table entries lead to an page overflow, I would assume, that all parent headers will be shown. But unfortunatley only the last (the deepest in the hierarchy) defined overflow header will be shown. Here you can see a quick example of it. (http://www.nemonon.de/HeaderProblem.xdp)
    Any help would be very welcome.
    Thanks and greetings,
    Joerg

    That will sure work for some requirements and thanks for the ideas. But this would fail for the second table. Perhaps my example xdp only shows the behaviour of the nested overflow headers and it´s structure is reduced to show that. The real situation is a bit different. The parent containers also contain some other content. The Problem is not the table...I've just chosen it to produce some content and another nested header. Just try to uncheck the overflow header of the table. This will lead to, that the next defined header (in this case "HeaderThree" is shown. When you go on by also disabling that header, the next one will be shown...and so on. This shows, that the headers for their own are functional, but they fail in combination.
    Greetings,

  • Strange behaviour with Subjective Assessments comments in SSM10 SP10

    Good day community,
    We have strange behaviour with Subjective Assessments comments in SSM10 SP10.
    We have been using this successfully for 3 quarters.
    The scenario is as follows.
    Business users capture Subjective Assessment comments successfully and these can be viewed on the scorecard overview for Q3. This can be printed to PDF successfully as well.
    A few hours later, when the user accesses the Scorecard Overview, the Q3(March 2014) comments are now replaced with the
    Q2(Dec 2013) comments. 
    This has not happened previously. We have recently deployed Internet Explorer (IE) 10 to some of the machines that previously used IE9 or IE8. Could this be a contributing factor?
    This has happened with one database on 2 contexts.  Although the database/scorecard in question has been created on SSM10, we have recently upgraded the rest of the organisation onto SSM10 from SSM7.5 but those are completely separate databases.
    We have not found a pattern yet, but there is only one assigned administrator for this database and she often has 'funny' things happen on her machine. Could it be possible that there's a virus on her machine? Or maybe there's a sequence or combination of steps that she's doing that could cause this? We have not been able to recreate the situation in our developer offices.
    Any ideas on this strange behaviour would be appreciated.
    Regards,
    Natasha

    Hi everyone,
    We have since noticed that if you go into the Administrator > Context Management > and change the "Person Responsible" and then save, once you go back to the Scorecard Overview all the Q3 comments have been overwritten with the Q2 comments.
    This happened on a different machine so it seems there could be a bug in the Administrator.
    Any thoughts on this strange behaviour would be appreciated.
    Regards,

  • Strange behaviour with my updating of combo box

    }I tried with the script above, the combo_box first got compiled nicely after retrieving data from the database.
    However, when i tried to do the updating of combo box with function currentVideoName, it fails.
    I also tried puttng a ComboBoxModel inside my function but it fails. It just doesn't get updated...
    ComboBoxModel model = new DefaultComboBoxModel(myVideoName);
    combo_Name.setModel(model);can someone advise me or show me some simple code on this?

  • View Master mode strange behaviour with jpg files

    Hy all,
    I'm using Aperture, and I'm tweakin a lot the SW to discover all secrets ....
    I'm really concerned about a strange behaviour of the SW in view mode.
    If I open a jpg file, do not apply ANY modification, and apply the "show master" command (pressing M), there's a subtle behaviour :
    *the images get sharper !!!!*
    It behaves as if an "edge sharpening" was applied !!!!!!
    With _RAW files this thing doesn't happen at all._
    Even stranger, if I zoom to full definition (by pressing Z), and toggle between normal view and "show master" view, the immage remains the same !
    The effect is not so evident with all images, but sometimes it is !!
    Anyway, I expect not to have such kind of things with a professional SW.
    With professional cameras and good quality files it's really annoying not to beeing sure what's the REAL content of the jpg image.
    Has anyone noted this thing ? Is there a reasonable explanation ?
    The only one I tried to figure out is the following : may be Aperture applies some kind of resampling algorithm with jpg files (bicubic, bilinear, etc).
    May be this resampling is not applied with 100% magnification, as weel as with raw files.
    But it's only my guessing. Now, I'm tweaking other viewers and other SW to understand what's the real jpg image stored in the file : the blurer one form normal view or the sharper one with "show master" mode.
    I stress once again : of course, the jpg file I'm talking about have no settings at all, just imported and toggled with M button.
    Thanks in advance.
    Regards,
    Enzo

    Hy,
    I'm afraid I'm not been clear.
    The problem is this :
    1) jpg image opened in normal view mode, no zoom, (no quick preview, of course) : image with a certain amount of blour
    2) jpg image opened in show master mode, no zoom, (no quick previre, of course) : image SHARPER with respect with the previous.
    No edit applied from import, so "show master" command shouln't apply any change in rendering, should it ?
    The only thing I said on 100% view is that such difference (between normal mode e show mastermode) is not present with 100% magnification.
    That was the issue.

  • Problem with combo boxes and the reset button in certain situations

    Hi Everyone,
    i have a problem to make the reset-button function properly in an what-if analysis dashboard.
    The dashboard uses two combo boxes that are not visible at the same time. In my application the second combo box only appears when a dedicated menu (label based menu button) has been activated.
    So i have combo box 1 when menu A is active an dand combo box 2 when menu 2 is active.
    After starting the dashboard initial values are fine. If you then directly change to menu 2 (seeing combo box 2 with
    the correct default value) and press the reset button, the dashboard returns to the initial view, showing
    the menu 1 with the correct default value. If you now switch back  to menu 2, you will see, that the combo box 2
    is empty (i.e. nothing selected).
    I also tracked the destination cells for the combo box value results as well as the source cells for the "selected item" and the
    destination cells for the "Insert Selected Item". All this values seem to be correct. Therefore i assume that
    this is an issue of event handling. Maybe the combo box 2 does not refresh its selected value because it is already
    invisible when the values are restored.
    This case can easily be simulated by placing two combo boxes and a push button (that changes the visibility of
    the combo boxes) and the reset button on the canvas.
    Maybe someone can help. I am able to provide a test xlf, if neccessary.
    Thanks,
    Oliver
    P.S. I am using Xcelsius SP4 (Version 5.4.0.0)

    Hello Debjit_Singha_86,
    thank you for your support. At the moment i have the following setting:
    label based menu
    - General: Insertion Type "value" from a list of ID's for the menu-items to a dedicated cell (current menu ID, say tab1!$A$1)
    - Behavior: Selected item (position) fixted to item 1
    hidden combo box
    - General: Insertion Type "position" to a dedicated cell with the current choice (say tab1!$B$1)
    - Behavior: Selected item (position) to the same cell (tab1!$B$1)
    Can you give me a hint on how to connect the two components according to your solution, so that the label based menu sets the default for the hidden combox box only in case, that the reset button is pressed?
    Thanks,
    Oliver

  • Problem with Combo Box in a Dialog Box

    I have a dialog box that includes a combo box.
    For some reason the combo box shows up under the first text box. In other words, the combo box is not separate from the first field. It has the following:
    ComboBox with Sequence showing, then Enter Identifyer
    Textbox URL
    Textbox Enter Resource 1
    Textbox Enter Resource 2
    Textbox Enter Resource 3
    Textbox Enter Resource 4
    Textbox Enter Resource 5
    It's putting the combo box in the first text field...it should be

    Enter Identifyer Textbox
    Enter Resource 1 Textbox
    Enter Resource 2 Textbox...

  • IPhoto: strange behaviour with preview thumbnails

    Is there a simple way in iPhoto 8 to rebuild the thumbnail database?
    I recently noticed a strange behaviour iPhoto 8 has with previews: In some of my event categories, iPhoto does not display the correct preview thumbnail of the picture, but a preview thumbnail of another event. When I click on the thumbnail, it reloads the appropriate preview and it does not happen again - with that picture. Also, if I double click an event to open it, the small thumbnail of the event's key photo that is to be displayed in the title bar (next to the All Events button) is not always correct.
    Thank you for your help!
    Stefan

    I have similar problems (lately) with iPhoto 6.0.6 -- thumbnails do not equal the images they 'thumbnail' of.
    Sometimes when it opens, it (recently) asked me to rebuild the thumbnails, but not always.
    Can I force a thumbnail rebuild using the command you gave - Apple-option while opening iPhoto? In iPhoto 6.0.6 this primarily forces a new selection of a library.

  • Strange behaviour with Slideshow placement since upgrade to 3.2 from 3.1

    Hello, since I upgrade from 3.1 to 3.2, I have some strange behaviours but in particular with the placement of a slideshow on a new page.  It is not displaying in the same position as I have in in Design.  It is way off and going up over my menus when I look at it in Safari or Chrome.  Does anyone know how to fix this or could it be a bug?

    Ben,
    When you upgrade, only apex_030200 will be created and that will use the tablespace you specify. It does not have to be the same one used by flows_030100.

  • Strange behaviour with smart music list in iTunes

    I don't know how is the name of this list in english. In portuguese iTunes calls "Lista Inteligente". So, I eddited a list to show all musics never played up to 100 months ago. If I click on a music in this list, before it plays, the music disappear from the list as it would be played and nothing will be played. And so one, the next and etc. No date is shown in "last play" but the music isn't anymore to see in this List.
    This list works well for many years but suddenly I have this strange behaviour.
    could it be something wrong with new update? Now I have iTunes installed 11.3.0.54

    Click the gray disclosure triangle in front of the iPod touch name.
    Thus I cannot do any functions with the music on my iPod - such as delete songs, update song info, etc.
    I would suggest making any changes to songs in iTunes and then transferring the songs to the touch.
    You can create playlists and autosync on lythos playlists.
    Then add/delete from those playlists, update items in iTunes then plug in the touch to sync it.

  • Filtering my DataGridView with Combo Boxes

    Hello everyone! I have recently started working with windows form application and I must say it is really
    awsome! I have came up with a project but I came across a little problem and I hope some of you might help me!
    I have established a local database and managed to connect it to a DataGridView, awsome I can see my database
    in my windows form! I have also made 7 combo boxes, each with its strings in it, then i added a button that should filter the data grid view according to the strings the user selected in the combo boxes. My question is, how do i do that? I mean how do i make
    the button fillter my DataGridView according to the strings selected in my combo boxes?
    Hope for a quick answer, sorry for my english and lack of knowledge in windows form!

    Maybe you could go this way:
    Populate the combobox manually, first adding "All", then adding the items from industryGroupsDataSet.Tables[0].
    Add a BindingSource between companiesDataSet.Tables[0] and dataGridView1.DataSource.
    In the SelectedIndexChanged event of the combobox, alter the Filter property of the BindingSource. If the selected index is zero ("All"), set the Filter to null, otherwise set the filter to String.Format("groupID = '{0}'", cmbBxGroupFilter.SelectedValue).
    You may also have a look at these too:
    filtering data from a
    data table to populate combo box on a datagridview based on the user selection

  • Glitch with combo boxes

    Hi all,
    In flash I have about 5 frames, each which have 7 combo boxes
    on them. The user selects the answers for each combo box and then
    clicks 'check' if they are correct they move on to the next frame.
    The only frame that is different is frame 3 which has combo boxes 4
    and 5 missing because they do not apply for that particular
    question.
    Once the user moves on past frame 3, some of the combo boxes
    show up blank (they are there but the default Index 0 "select" does
    not show up. If you click on the combo box it opens and you can
    choose one of the 5 choices in it, but once you select one it won't
    show up either.
    Does anyone know the cause of this problem or a solution?
    P.S. The combo boxes all have the same instance name
    throughout the whole file of 'cbo1' through 'cbo7' and are reset to
    index 0 at the beginning of each new frame.

    You do this by combining JSPs with a central servlet. I don't know how to do it with just one JSP on its own.
    The JSP does a <form> POST to the servlet. The servlet fetches the combo box values into a List, puts it into request scope, and forwards the response back to the JSP. The JSP gets the List out of request scope and populates the drop-down. You do the same thing when there's a selection in the drop-down: onChange does a POST back to the servlet, which gets the selected value as a parameter, takes the appropriate action, and forwards the response with new data in request scope back to the JSP.
    The trick is to have the data in request scope so the JSP can get it. I think you need a servlet to do that.
