Apex.submit issue when using jQuery Overlay

Dear All,
This is my first post in this forum and I hope I can find a solution for my issue.
Currently we are developing a new Time Attendance System by Apex.
I am facing a problem when I use the jQuery Overlay in one of the pages.
the page it self is working fine and all it button and tabs are also working fine until I click the link for the overlay content
the content is another page getting loaded in a similer to a popup window (overlay effect) after I close this overlay window
all the links in the original page that are using the apex.submit are not working and show an error in the browser "Object doesn't support this method or property"
This only occur when I click the overlay link but if I load the page and I don't open the overlay link all links are working fine.
And Thank you all inadvance.
Regards

It's always easier to debug an issue like this by recreating the problem on apex.oracle.com and providing credentials.
How did you set up the overlay content? Did you create any additional HTML elements within one of the apex regions? If was just adding some DIV content then try moving that DIV content to after the #FORM_CLOSE# substitution string in the page template.

  • JTable text alignment issues when using JPanel as custom TableCellRenderer

    Hi there,
    I'm having some difficulty with text alignment/border issues when using a custom TableCellRenderer. I'm using a JPanel with GroupLayout (although I've also tried others like FlowLayout), and I can't seem to get label text within the JPanel to align properly with the other cells in the table. The text inside my 'panel' cell is shifted downward. If I use the code from the DefaultTableCellRenderer to set the border when the cell receives focus, the problem gets worse as the text shifts when the new border is applied to the panel upon cell selection. Here's an SSCCE to demonstrate:
    import java.awt.Color;
    import java.awt.Component;
    import java.awt.EventQueue;
    import javax.swing.GroupLayout;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JPanel;
    import javax.swing.JTable;
    import javax.swing.border.Border;
    import javax.swing.table.TableCellRenderer;
    import javax.swing.table.TableColumn;
    import sun.swing.DefaultLookup;
    public class TableCellPanelTest extends JFrame {
      private class PanelRenderer extends JPanel implements TableCellRenderer {
        private JLabel label = new JLabel();
        public PanelRenderer() {
          GroupLayout layout = new GroupLayout(this);
          layout.setHorizontalGroup(layout.createParallelGroup().addComponent(label));
          layout.setVerticalGroup(layout.createParallelGroup().addComponent(label));
          setLayout(layout);
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
          if (isSelected) {
            setBackground(table.getSelectionBackground());
          } else {
            setBackground(table.getBackground());
          // Border section taken from DefaultTableCellRenderer
          if (hasFocus) {
            Border border = null;
            if (isSelected) {
              border = DefaultLookup.getBorder(this, ui, "Table.focusSelectedCellHighlightBorder");
            if (border == null) {
              border = DefaultLookup.getBorder(this, ui, "Table.focusCellHighlightBorder");
            setBorder(border);
            if (!isSelected && table.isCellEditable(row, column)) {
              Color col;
              col = DefaultLookup.getColor(this, ui, "Table.focusCellForeground");
              if (col != null) {
                super.setForeground(col);
              col = DefaultLookup.getColor(this, ui, "Table.focusCellBackground");
              if (col != null) {
                super.setBackground(col);
          } else {
            setBorder(null /*getNoFocusBorder()*/);
          // Set up our label
          label.setText(value.toString());
          label.setFont(table.getFont());
          return this;
      public TableCellPanelTest() {
        JTable table = new JTable(new Integer[][]{{1, 2, 3}, {4, 5, 6}}, new String[]{"A", "B", "C"});
        // set up a custom renderer on the first column
        TableColumn firstColumn = table.getColumnModel().getColumn(0);
        firstColumn.setCellRenderer(new PanelRenderer());
        getContentPane().add(table);
        pack();
      public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
          public void run() {
            new TableCellPanelTest().setVisible(true);
    }There are basically two problems:
    1) When first run, the text in the custom renderer column is shifted downward slightly.
    2) Once a cell in the column is selected, it shifts down even farther.
    I'd really appreciate any help in figuring out what's up!
    Thanks!

    1) LayoutManagers need to take the border into account so the label is placed at (1,1) while labels just start at (0,0) of the cell rect. Also the layout manager tend not to shrink component below their minimum size. Setting the labels minimum size to (0,0) seems to get the same effect in your example. Doing the same for maximum size helps if you set the row height for the JTable larger. Easier might be to use BorderLayout which ignores min/max for center (and min/max height for west/east, etc).
    2) DefaultTableCellRenderer uses a 1px border if the UI no focus border is null, you don't.
    3) Include a setDefaultCloseOperation is a SSCCE please. I think I've got a hunderd test programs running now :P.

  • Odd issue when using UDT (user defined type)

    Hi all,
    11g.
    I ran into an odd issue when using UDT, I have these 4 schemas: USER_1, USER_2, USER_A, USER_B.
    Both USER_1 and USER_2 have an UDT (actually a nested table):
    CREATE OR REPLACE TYPE TAB_NUMBERS AS TABLE OF NUMBER(10)USER_A has a synonym points to the type in USER_1:
    create or replace synonym TAB_NUMBERS for USER_1.TAB_NUMBERS;USER_B has a synonym points to the type in USER_2:
    create or replace synonym TAB_NUMBERS for USER_2.TAB_NUMBERS;Both USER_A and USER_B have a procedure which uses the synonym:
    CREATE OR REPLACE PROCEDURE proc_test (p1 in tab_numbers)
    IS
    BEGIN
      NULL;
    END;And in the C# code:
    OracleConnection conn = new OracleConnection("data source=mh;user id=USER_A;password=...");
    OracleCommand cmd = new OracleCommand();
    cmd.Connection = conn;
    cmd.CommandText = "proc_test";
    cmd.CommandType = CommandType.StoredProcedure;
    OracleParameter op = new OracleParameter();
    op.ParameterName = "p1";
    op.Direction = ParameterDirection.Input;
    op.OracleDbType = OracleDbType.Object;
    op.UdtTypeName = "TAB_NUMBERS";
    Nested_Tab_Mapping_To_Object nt = new Nested_Tab_Mapping_To_Object();
    nt.container = new decimal[] { 1, 2 };
    op.Value = nt;
    ......This code works fine, but it raises an error when I change the connection string from USER_A to USER_B, the error says:
    OCI-22303: type ""."TAB_NUMBERS" not foundInterestingly, if I change op.UdtTypeName = "TAB_NUMBERS"; to op.UdtTypeName = "USER_2.TAB_NUMBERS", the error is gone, and everything works fine.
    Anyone has any clues?
    Thanks in advance.

    Erase and reformat the ext HD. Then, redo the SuperDuper! backup.

  • Bluetooth issues when using smartwatch on the z1s

    I'm having some Bluetooth issues when using my smartwatch. I usually use my z1s with my car radio via Bluetooth to listen to music and for making calls. Now that I got a sony smartwatch I always got problems with the calls. It looks like that the Bluetooth turns off during the call when I'm using the smartwatch. I already tried by deleting and pairing again the z1s, but nothing works. Not sure if maybe the z1s does not support the smartwatch and the care radio Bluetooth connection at the same time. However it works fine when playing music! The problem is just with the calls. This never happens before I got the smartwatch.

    I have the Tmobile Z1s and a SW2 and have the same issues with multiple devices:
    1) Bose Soundlink Mini
    2) Sony MBR-100
    3) My car's bluetooth
    4) Ford Sync
    5) Sony SBH20
    6) Motorola S305
    If the phone connects to the A2DB device, it will typically play fine for several minutes. Then, audio will drop out. If I do nothing, after several minutes my watch will vibrate to show it has disconnected. Sometimes audio then comes back, and sometimes it doesn't.
    Sometimes my phone will not connect to my car. Then, if I can get it to connect, it will only allow for phone audio, not media audio. 
    This issue has been on (2) Z1s's with the SW2. The first I returned due to touch screen issues, which the second one also has. All of the devices above worked perfectly fine with my Xperia Z, Galaxy S2, HTC One, etc. The Xperia Z and the SW2 never had any problems.
    Honestly, this phone has been incredibly frustrating. If the upcoming updates for either the SW2 or Z1S don't fix this issue, I'm going to return it and get something else.

  • Smartform font spacing Issue when using SAP printer name

    Hi Friends,
    I am facing some spacing issues when printing a form using SAP printer name. If I use LOCL then the output comes perfectly but when I use the SAP printer name the space between characters are getting widened and so the alignment of each column goes wayward. I suspect it could be due to the device type but not sure which seeting controls this. There is a similar problem in the logo as well. When using LOCL the logo comes out good but when using the printer name the quality is not good and becomes pixelised. Have any of you faced similar issues? Can you provide some guidance or pointers for the solution.
    Device type of LOCL : ZSAPWIN
    Device type of SAP printer name :  ZHPLJ5
    CPI is defined in smartform as 10.
    Please let me know if you need more information.
    Thanks,
    Praveen

    Hi,
    This problem occurs because the printer driver for both the printers are different,
    I suggest you use Local printer only or configure any other printer with printer diver in SAP as SAPWIN.
    Regards,
    Bharat.

  • Performance issues when using Smart View and Excel 2010

    Hello, we are experiencing very slow retrieval times when using Smart View and Excel 2010. Currently on v.11.1.3.00 and moved over from Excel 2003 in the last quarter. The same spreadsheets in 2010 (recreated) are running much slower than they used to in 2003 and I was wondering if anyone else out there has experienced similar problems?
    It looks like there is some background caching going on as when you copy and paste the contents into a new file and retrieve it is better.....initially. The size of the files are generally less than 2mb and there aren't an expecially large number of subcubes requested so I am at a loss to explain or alleviate the issues.
    Any advice / tips on how to optimise the performance would be greatly appreciated.
    Thanks,
    Nick

  • QBE issue when using different db types

    Hello,
    Our ADF application has the ability to connect to the same schema but different backends (Oracle and SQL Server). I have successfully implemented switching the AM data source. I am running into a syntax issue when performing Query By Example for a table. The error is (Incorrect Syntax near "|"). In the VOImpl I overrode the function public String getViewCriteriaClause(boolean forQuery) and I can see the viewCriteriaClause is "( (UPPER(TransMasterEO.TMMessage) LIKE UPPER( ? || '%') ) )". This works when running against the Oracle instance but fails when running against the SQL Server instance.
    I implemented code to replace the "||" with "+" but then we fail on Oracle. Can someone recommend an approach to resolve?
    Running 11.1.1.6
    Thank you
    Rudy

    he different dbs yre using different sql flavors. This is causing trouble if you change the connection to a db which is using a different flavor. I'm not aware that you can change the flavor used to build the queries to, but you can implement your own sqlbuilder which may just extend from the one for hte right flavor and then build the sql through the right class.
    Check http://jobinesh.blogspot.com/2013/02/customizing-sql-builder-class.html for more info on how to change the sqlbuilder.

  • Issue when using Navigation attributes for filtering in BEX

    Hello,
    We are encountering an issue when applying filter on Navigation attributes in BEx query built on top of a BW HANA Virtual Provider.
    The interface is as below :
    HANA Calculation View -> SAP BW 7.4 Virtual InfoCube -> Multiprovider -> BEx Query.
    We have directly mapped the base Infoobject from HANA View to BW Virtual Provider and using this in BEx query free characteristics. We also have used the navigational attribute of this Infoobject in our Report variable screen as well as an Auth relevant object.
    Eg if ZMATERIAL is the base infoobject and ZMATERIAL__ZXYZ navigational attribute is used in the report variable screen and as Authorization variable.
    This is causing the query to fail.
    The query also fails if I apply any filter values on any Navigational attribute with error message  :
    "Termination message sent ERROR DBMAN (305): Error reading the data of InfoProvider"
    Using the navigational attribute with authorization variable fails with below :
    "Termination message sent ERROR DBMAN (099): Invalid query;Failed to find attribute ZMATERIAL__ZXYZ [...]"
    Appreciate any inputs on this issue and how this can be fixed.
    Thanks,
    Tintu

    Hi Andrey,
    Thank you for your input.
    Based on the OSS note , it says to import BW7.4 SP7. We are already on BW7.4 SP7
    We get error "Termination message sent ERROR DBMAN (099): Invalid query;Failed to find attribute
    ZMATERIAL__ZXYZ"  whenever we try to apply filters on any of the navigational attribute.
    Thanks,

  • XML Parse issues when using Network Data Model LOD with Springframework 3

    Hello,
    I am having issues with using using NDM in conjuction with Spring 3. The problem is that there is a dependency on the ConfigManager class in that it has to use Oracle's xml parser from xmlparserv2.jar, and this parser seems to have a history of problems with parsing Spring schemas.
    My setup is as follows:
    Spring Version: 3.0.1
    Oracle: 11GR2 and corresponding spatial libraries
    Note that when using the xerces parser, there is no issue here. It only while using Oracle's specific parser which appears to be hard-coded into the ConfigManager. Spring fortunately offers a workaround, where I can force it to use a specific parser when loading the spring configuration as follows:
    -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl But this is an extra deployment task we'd rather not have. Note that this issue has been brought up before in relation to OC4J. See the following link:
    How to change the defaut xmlparser on OC4J Standalone 10.1.3.4 for Spring 3
    My question is, is there any other way to configure LOD where it won't have the dependency on the oracle parser?
    Also, fyi, here is the exception that is occurring as well as the header for my spring file.
    org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:

    I ran into this exact issue while trying to get hibernate and spring working with an oracle XMLType column, and found a better solution than to use JVM arguments as you mentioned.
    Why is it happening?
    The xmlparserv2.jar uses the JAR Services API (Service Provider Mechanism) to change the default javax.xml classes used for the SAXParserFactory, DocumentBuilderFactory and TransformerFactory.
    How did it happen?
    The javax.xml.parsers.FactoryFinder looks for custom implementations by checking for, in this order, environment variables, %JAVA_HOME%/lib/jaxp.properties, then for config files under META-INF/services on the classpath, before using the default implementations included with the JDK (com.sun.org.*).
    Inside xmlparserv2.jar exists a META-INF/services directory, which the javax.xml.parsers.FactoryFinder class picks up and uses:
    META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines oracle.xml.jaxp.JXDocumentBuilderFactory as the default)
    META-INF/services/javax.xml.parsers.SAXParserFactory (which defines oracle.xml.jaxp.JXSAXParserFactory as the default)
    META-INF/services/javax.xml.transform.TransformerFactory (which defines oracle.xml.jaxp.JXSAXTransformerFactory as the default)
    Solution?
    Switch all 3 back, otherwise you'll see weird errors.  javax.xml.parsers.* fix the visible errors, while the javax.xml.transform.* fixes more subtle XML parsing (in my case, with apache commons configuration reading/writing).
    QUICK SOLUTION to solve the application server startup errors:
    JVM Arguments (not great)
    To override the changes made by xmlparserv2.jar, add the following JVM properties to your application server startup arguments.  The java.xml.parsers.FactoryFinder logic will check environment variables first.
    -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
    However, if you run test cases using @RunWith(SpringJUnit4ClassRunner.class) or similar, you will still experience the error.
    BETTER SOLUTION to the application server startup errors AND test case errors:
    Option 1: Use JVM arguments for the app server and @BeforeClass statements for your test cases.
    System.setProperty("javax.xml.parsers.DocumentBuilderFactory","com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
    System.setProperty("javax.xml.parsers.SAXParserFactory","com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");
    System.setProperty("javax.xml.transform.TransformerFactory","com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
    If you have a lot of test cases, this becomes painful.
    Option 2: Create your own Service Provider definition files in the compile/runtime classpath for your project, which will override those included in xmlparserv2.jar.
    In a maven spring project, override the xmlparserv2.jar settings by creating the following files in the %PROJECT_HOME%/src/main/resources directory:
    %PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default)
    %PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default)
    %PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)
    These files are referenced by both the application server (no JVM arguments required), and solves any unit test issues without requiring any code changes.
    This is a snippet of my longer solution for how to get hibernate and spring to work with an oracle XMLType column, found on stackoverflow.

  • Slicing image issue when using "save for web"

    Keep in mind I am a newbi to photoshop and these forums. I am currently having an issue with using the slice tool when trying to save the image in html format. I have my image completed and when I use the  "save for web" feature, it comes up just fine. Then I click the slice tool on the tool bar on the left, and try to drag over the area that I want to slice and it wont work. Currently, every time I try to use the save for when feature, the new box pops up and shows my image with a 1 and a symbol on the top left of the image like the whole image is already made into a slice. The only thing I can do is left click and hold to drag the transparent box to where I want to slice the image, and when I let go, the image does not slice. Any help would be great!

  • Issue when using broadcaster in query desinger

    Hi All,
            we are having issues when we try to either distribute workbooks, it comes with a workbook page but nothing shows up on the page,samething when I try from
    query designer and try to publish it using broadcaster,the page does not show up anything.I am not sure why is it doing that.It was working before where it asked me onnce i distributed a workbook to make a new setting to broadcast the workbook.
    Your answere are greatly appreciated and will assign maximum points if it is solved.
    Regards
    Abyie

    Hi Gurus,
    I was able to sucessfully configure the Launch_Broadcaster. Now the broadcast settings in web template work same as the one when we launch the query to web from query designer(SEND, button function). However the broadcaster in web template(WAD) does not have XML(Ms Excel) output format. It has only MHTML, HTML, PDF & Online Link to Current Data.
    Is there a setting we need to perform in order to have XML(Excel) output format in WAD reports. Please advise.
    Thanks Much!

  • Audio export issue when using Multiband Compressor

    I'm having an audio issue when exporting from Premiere Pro 5.5. I have a number of clips that I've used the Multiband Compressor on. Some audio clips are straight cuts with no gaps, some have a 3-frame cross fade. When playing back in Premiere everything sounds fine. When I export the sequence the audio drops out for about a frame in between each audio clip which contains the Multiband Compressor effect. This occurs no matter what codec used during export, and when only audio is exported.

    I have the same problem. EXACTLY. I thought I became crazy, but not. What a pity, because Multiband Compressor is really impressive for a lot of situation, especially when there is voice.

  • IE6 layout issue when using HttpServeletResponseWrapper

    The problem is that this only happens with IE6!? when using IE7, FireFix or Chrome it doesn't reproduce!?
    Any ideas?
