Bug in ClassGeneratorWizard in ExtensionSDK on Jdev10.1.3.2

I'm running the ExtensionsSDK version 10.1.3.40.66 on jdeveloper 10.1.3.2.0.4066, which is a little old but not much. I've been trying to learn how to write a Wizard extension and am studying this example.
I deployed the extension, and it will load up and go through two pages, but when I hit "finish" I get the error "cannot create node content." Looking through the code, this seems like a fatal error in the generation. What must be done to correct this behavior - if you can reproduce the error? I tried to add some lines to get a stack trace and run jdev in debug mode, but so far have had issues.
Thanks for the help.

Hi Frank,
Thanks you are right !! I'm sure I had tried that syntax - but i must have instead used something like the following which did not work
@DeclareRoles (String[] {"userA", "userB", "admin"})
Anyway, Debu's EJB 3 in Action page 208 lists the syntax as
@DeclareRoles("userA", 'userB", "admin")
so that is definitely something to add to the errata.
thanks for your help.
matt.

  • JDev10.1.3EA Find in Files Bug

    Could you pls review
    JDev10.1.3EA Find in Files big files size limit
    looks like the size limit only works for the first (big) file,
    Thanks in advance

    Hi,
    can you explain a bit more what you mean? Did you set a size limit on the max. file size to compare ?

  • Is this a bug of JAAS/JAZN  in JDev 10.1.3 ?

    Hi All,
    I implement file based security eith JAAS and JDev10.1.3, that works but there are two strange things that I wonder where it is bug :
    1.) When I go to JAZN Data Properties from JDev , I see many 'uncreated' users like : DataBase_User_zbLu50HDPQULTOUZkmbSn3fjEowJ-YHy, DataBase_User_lE4mfb1ETJPcD3sOeYaSfiHw3n0hM8BQ etc, what are these ?
    (they get deployed also when I deploy the app to OC4J)
    2) When I deploy to OC4J stand alone, my real users I created from JDev for testing do not seem to get deployed, only the 'garbage' users that I mentioned above get deployed.
    On the OC4J Server, to make it workm I have to manually copy : jazn-data.xml
    FROM : C:\OC4J\j2ee\home\applications\MyApp\MyAppViewArchive\WEB-INF\classes\META-INF
    TO : C:\OC4J\j2ee\home\application-deployments\MyApp
    Is this also a bug ?
    Thank you for your help,
    xtanto

    Xtanto,
    1) what you call "garbage" users are the database connects you have defined in JDeveloper. You can delete them from jazn-data.xml before deployment. The "garbage" you see is used for password indirection, to make sure the clear password is not added to the jazn-data.xml file
    2) Create jazn-data.xml file in your project. Add the users you like to use. Then create orion-application.xml in the same project, which by default points to the jazn-data.xml file in the project. This then should make OC4J using the jazn-data.xml file of your project instead of generating a new one

  • SubTabLayout problem with PPR (bug?)

    Hello,
    I'm using JDev10.1.2 and found out that subTabLayout does not respond to the partial page rendering (PPR) as one would expect.
    In my example there is simple subtabs switching that does not renders both subtabs, only upper one is changing.
    Correct behavior can be achieved if using fireAction instead of firePartialAction.
    Is this a bug?
    Example:
    <subTabLayout>
      <contents>
        <messageStyledText text="${sessionScope.subTabIndex}" prompt="Selected tab:" id="message"/>
      </contents>
      <subTabs>

    hi Jan Vervecken
    Thank you for your reply.
    I have found the problem,it's as the following:
    The files above are ok,but the files in another application are not ok,or the connect that i have configed are not working well. I deleted the extra applications and the connection in my jdeveloper,now it works well....
    i think it's a bug in jdeveloper.
    again,thank you

  • Problem while migrating code from JDev 9.04 to JDev10.1.3

    I have migrated code from JDev 9.04 to JDev10.1.3, in that i am using a customised Combo Box which is using JUPanelBinding in setModel.But that Combo Box is not displayed properly as of 9.0.4. Also when i tried to print JUPanelBinding value it is giving as - noPanel_oracle_jbo_uicli_jui_JUPanelBinding_1.
    Where is the problem ? (in panel binding or in setModel )
    Can anyone suggest me a solution for that ?

    It's a regression. I filed bug 5703242.
    As a workaround you could specify sequence name with the qulifier:
      aSequence.setTableName("TEST.SEQUENCE");Alternatively you could override TableSequence class:
    public class MyTableSequence extends TableSequence {
        public void onConnect() {
            qualifier = getDatasourcePlatform().getTableQualifier();
            super.onConnect();
    }I apologize for the inconvenience,

  • Is JDeveloper bug?

    hi
    I work with jdev10.1.3 and recently i found the application module configuration setting function sometime can't work.When i right click on the application module tree node will popup function list and each function work fine just only Configurations can't work.
    Is this a JDeveloper bug?Is there other way to set application module configuration?

    Hi,
    not sure why you hope that this is a bug?
    Swing does support internationalization and JDeveloper supoorts this. However, as usual in Swing, you have to develop it as tehre is no automated way for doing this.
    There is some help provided by ADF in that e..g. BC4J supports message bundles for translating Strings.
    See: http://java.sun.com/docs/books/tutorial/i18n/index.html
    Also, straight from the JDeveloper product page on OTN, though not directly Swing related

  • Solaris8 and 9 (possibly 7) /dev/poll driver bug report.

    Hello,
    I'd like to report a bug in the solaris 8 and 9 /dev/poll driver (poll(7d)).
    As i do not have a support account with sun or anything like that, there
    seems to be no other way to do that here (which is of course a very sad
    thing).
    Bug details:
    The /dev/poll device provides an ioctl-request (DP_ISPOLLED) for checking
    if a particular filedescriptor is currently in the set of monitored
    filedescriptors for that particular /dev/poll fd set (open /dev/poll fd).
    A quote from the documentation of the poll(7d) manual page taken from
    Solaris9:
    "DP_ISPOLLED ioctl allows you to query if a file descriptor is already in
    the monitored set represented by fd. The fd field of the pollfd structure
    indicates the file descriptor of interest. The DP_ISPOLLED ioctl returns 1
    if the file descriptor is in the set. The events field contains the
    currently polled events. The revents field contains 0. The ioctl returns 0
    if the file descriptor is not in the set. The pollfd structure pointed by
    pfd is not modified. The ioctl returns a -1 if the call fails."
    It says that when you query for an filedescriptor which is currently being
    monitored in the set, that it would return 1, and change the events field of
    the pollfd structure to the events it's currently monitoring that fd for.
    The revents field would be set to zero.
    However the only thing which actually happens here, is that FD_ISPOLLED
    returns 1 when the fd is in the set and 0 if not. When the fd is in the
    set, when FD_ISPOLLED returns 1, the events field remains unmodified, but
    the revents field gets changed.
    A small sample code to illustrate:
    #include <stdio.h>
    #include <unistd.h>
    #include <sys/types.h>
    #include <sys/stat.h>
    #include <fcntl.h>
    #include <sys/devpoll.h>
    main() {
    struct pollfd a;
    int dp_fd = open("/dev/poll", O_WRONLY);
    a.fd = 0; /* stdin */
    a.events = POLLIN; /* we monitor for readability, POLLIN=1 */
    a.revents = 0;
    write(dp_fd, &a, sizeof(a));
    a.fd = 0;
    a.events = 34; /* filled in with bogus number to show malfunctioning */
    a.revents = 0;
    printf("DP_ISPOLLED returns: %d\n", ioctl(dp_fd, DP_ISPOLLED, &a));
    printf("a.fd=%d, a.events=%hd, a.revents=%hd\n", a.fd, a.events,
    a.revents);
    According to the documentation of /dev/poll and namely DP_ISPOLLED this
    program is supposed to print the following:
    DP_ISPOLLED returns: 1
    a.fd=0, a.events=1, a.revents=0
    However it prints the following:
    DP_ISPOLLED returns: 1
    a.fd=0, a.events=34, a.revents=1
    You can take any number instead of '34' and it will simply remain untouched
    after the DP_ISPOLLED ioctl-request.
    I hope it's clear now that the solaris8 and solaris9 (and probably solaris7
    with /dev/poll patch too) DP_ISPOLLED implementation is broken.
    This bug is also easily illustrated by looking at the solaris8 kernel sourcecode:
    <snippet osnet_volume/usr/src/uts/common/io/devpoll.c:dpioctl()>
    case DP_ISPOLLED:
    pollfd_t pollfd;
    polldat_t *pdp;
    if (pollfd.fd < 0) {
    mutex_exit(&pcp->pc_lock);
    break;
    pdp = pcache_lookup_fd(pcp, pollfd.fd);
    if ((pdp != NULL) && (pdp->pd_fd == pollfd.fd) &&
    (pdp->pd_fp != NULL)) {
    pollfd.revents = pdp->pd_events;
    if (copyout(&pollfd, (caddr_t)arg,
    sizeof(pollfd_t))) {
    mutex_exit(&pcp->pc_lock);
    DP_REFRELE(dpep);
    return (set_errno(EFAULT));
    *rvalp = 1;
    </snippet>
    its' clearly visible that the code writes the current monitored events to
    the revents field:
    'pollfd.revents = pdp->pd_events;'
    and that it doesnt set revents to zero.
    It's funny to see that this has been like this since Solaris8 (possibly 7). That means nobody ever used DP_ISPOLLED that way or people were simply to lazy to file a bug report.
    Another funny thing related to this. is that Hewlett-Packard did seem to know about this. Since HP-UX11i version 1.6 they also support /dev/poll. From their manual page i ll quote some sentences from their WARNING session:
    "The ioctl(DP_ISPOLLED) system call also returns its result in the revents member of the pollfd structure, in order to be compatible with the implementation of the /dev/poll driver by some other vendors."
    Hopefully this will get fixed.
    I also like to reexpress my very negative feelings towards the fact that you're not able to file bug reports when you do not have a support contract. Ridiculous.
    Thanks,
    bighawk

  • [bdb bug]repeatly open and close db may cause memory leak

    I had read bdb's source code before, so i tried to debug it for about a week and found something like a bug:
    If open a db with both filename and dbname, bdb will open a db handle for master db and a db handle for subdb,
    both of the two handle will get an fileid by a internal api called __dbreg_get_id, however, just the subdb's id will be
    return to bdb's log region by calling __dbreg_pop_id. It leads to a id leak if I tried to open and close the db
    repeatly, as a result, __dbreg_add_dbentry will call realloc repeatly to enlarge the dbentry area, this seens to be
    the reason for RSS increasing.
    Is it not a BUG?
    sorry for my pool english :)

    I have tested my program using Oracle Berkeley DB release 4.8.26 and 4.7.25 in redhat 9.0 (Kernel 2.4.20-8smp on an i686) and AIX Version 5.
    The problem is easy to be reproduced by calling the open method of db handle with both filename and dbname being specified and calling the close method.
    My program is very simple:
    #include <stdlib.h>
    #include <stdio.h>
    #include <sys/time.h>
    #include "db.h"
    int main(int argc, char * argv[])
    int ret, count;
    DB_ENV *dbenvp;
    char * filename = "test.dbf";
    char * dbname = "test";
    db_env_create(&dbenvp, 0);
    dbenvp->open(dbenvp, "/home/bdb/code/test/env",DB_CREATE|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_TXN|DB_INIT_MPOOL, 0);
    for(count = 0 ; count < 10000000 ; count++)
    DB *dbp;
    DB_TXN *txnp;
    db_create(&dbp,dbenvp, 0);
    dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
    ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
    if(ret != 0)
    printf("failed to open db:%s\n",db_strerror(ret));
    return 0;
    txnp->commit(txnp, 0);
    dbp->close(dbp, DB_NOSYNC);
    dbenvp->close(dbenvp, 0);
    return 0;
    DB_CONFIG is like below:
    set_cachesize 0 20000 0
    set_flags db_auto_commit
    set_flags db_txn_nosync
    set_flags db_log_inmemory
    set_lk_detect db_lock_minlocks

  • Multiple return values (Bug-ID 4222792)

    I had exactly the same request for the same 3 reasons: strong type safety and code correctness verification at compile-time, code readability and ease of mantenance, performance.
    Here is what Sun replied to me:
    Autoboxing and varargs are provided as part of
    JSRs 14 and 201
    http://jcp.org/en/jsr/detail?id=14
    http://jcp.org/en/jsr/detail?id=201
    See also:
    http://forum.java.sun.com/forum.jsp?forum=316
    http://developer.java.sun.com/developer/earlyAccess/adding_generics/index.html
    Multiple return values is covered by Bug-ID 4222792
    Typically this is done by returning an array.
    http://developer.java.sun.com/developer/bugParade/bugs/4222792.html
    That's exactly the problem: we dynamically create instances of array objects that would better fit well within the operand stack without stressing the garbage collector with temporary Array object instances (and with their backing store: 2 separate allocations that need to be recycled when it is clearly a pollution that the operand stack would clean up more efficiently)
    If you would like to engage in a discussion with the Java Language developers, the Generics forum would be a better place:
    http://forum.java.sun.com/forum.jsp?forum=316
    I know that (my report was already refering to the JSR for language extension) Generics is not what I was refering to (even if a generic could handle multiple return values, it would still be an allocated Object
    instance to pack them, i.e. just less convenient than using a static class for type safety.
    The most common case of multiple return values involve values that have known static datatypes and that should be checked with strong typesafety.
    The simple case that involves returning two ints then will require at least two object instances and will not solve the garbage collection overhead.
    Using a array of variable objects is exactly similar, except that it requires two instances for the components and one instance for the generic array container. Using extra method parameters with Integer, Byte, ... boxing objects is more efficient, but for now the only practical solution (which causes the least pollution in the VM allocator and garbage collector) is to use a custom class to store the return values in a single instance.
    This is not natural, and needlessly complexifies many interfaces.
    So to avoid this pollution, some solutions are used such as packing two ints into a long and returning a long, depacking the long after return (not quite clean but still much faster at run-time for methods that need to be used with high frequencies within the application. In some case, the only way to cut down the overhead is to inline methods within the caller code, and this does not help code maintenance by splitting the implementation into small methods (something that C++ can do very easily, both because it supports native types parameters by reference, and because it also supports inline methods).
    Finally, suppose we don't want to use tricky code, difficult to maintain, then we'll have to use boxing Object types to allow passing arguments by reference. Shamely boxed native types cannot be allocated on the operand stack as local variables, so we need to instanciate these local variables before call, and we loose the capacity to track the cases where these local variables are not really initialized by an effective call to the method that will assign them. This does not help debugging, and is against the concept of a strongly typed language like Java should be:
    Java makes lots of efforts to track uninitialized variables, but has no way to determine if an already instanciated Object instance refered in a local variable has effectively received an effective assignment because only the instanciation is kept. A typical code will then need to be written like this:
    Integer a = null;
    Integer b = null;
    if (some condition) {
    //call.method(a, b, 0, 1, "dummy input arg");
    // the method is supposed to have assigned a value to a and b,
    // but can't if a and b have not been instanciated, so we perform:
    call.method(a = new Integer(), b = new Integer(), 0, 1, "dummy input
    arg");
    // we must suppose that the method has modified (not initialized!)
    the value
    // of a and b instances.
    now.use(a.value(), b.value())
    // are we sure here that a and b have received a value????
    // the code may be detected at run-time (a null exception)
    // or completely undetected (the method() above was called but it
    // forgot to assign a value to its referenced objects a and b, in which
    // case we are calling in fact: now.use(0, 0); with the default values
    // or a and b, assigned when they were instanciated)
    Very tricky... Hard to debug. It would be much simpler if we just used:
    int a;
    int b;
    if (some condition) {
    (a, b) = call.method(0, 1, "dummy input arg");
    now.use(a, b);
    The compiler would immediately detect the case where a and b are in fact not always initialized (possible use bere initialization), and the first invoked call.method() would not have to check if its arguments are not null, it would not compile if it forgets to return two values in some code path...
    There's no need to provide extra boxing objects in the source as well as at run-time, and there's no stress added to the VM allocator or garbage collector simply because return values are only allocated on the perand stack by the caller, directly instanciated within the callee which MUST (checked at compile-time) create such instances by using the return statement to instanciate them, and the caller now just needs to use directly the variables which were referenced before call (here a and b). Clean and mean. And it allows strong typechecking as well (so this is a real help for programmers.
    Note that the signature of the method() above is:
    class call {
    (int, int) method(int, int, String) { ... }
    id est:
    class "call", member name "method", member type "(IILjava.lang.string;)II"
    This last signature means that the method can only be called by returning the value into a pair of variables of type int, or using the return value as a pair of actual arguments for another method call such as:
    call.method(call.method("dummy input arg"), "other dummy input arg")
    This is strongly typed and convenient to write and debug and very efficient at run-time...

    Can anyone give me some real-world examples where
    multiple return values aren't better captured in a
    class that logically groups those values? I can of
    course give hundreds of examples for why it's better
    to capture method arguments as multiple values instead
    of as one "logical object", but whenever I've hankered
    for multiple return values, I end up rethinking my
    strategy and rewriting my code to be better Object
    Oriented.I'd personally say you're usually right. There's almost always a O-O way of avoiding the situation.
    Sometimes though, you really do just want to return "two ints" from a function. There's no logical object you can think of to put them in. So you end up polluting the namespace:
    public class MyUsefulClass {
    public TwoInts calculateSomething(int a, int b, int c) {
    public static class TwoInts {
        //now, do I use two public int fields here, making it
        //in essence a struct?
       //or do I make my two ints private & final, which
       //requires a constructor & two getters?
      //and while I'm at it, is it worth implementing
      //equals(), how about hashCode()? clone()?
      //readResolve() ?
    }The answer to most of the questions for something as simple as "TwoInts" is usually "no: its not worth implementing those methods", but I still have to think about them.
    More to the point, the TwoInts class looks so ugly polluting the top level namespace like that, MyUsefulClass.TwoInts is public, that I don't think I've ever actually created that class. I always find some way to avoid it, even if the workaround is just as ugly.
    For myself, I'd like to see some simple pass-by-value "Tuple" type. My fear is it'd be abused as a way for lazy programmers to avoid creating objects when they should have a logical type for readability & maintainability.
    Anyone who has maintained code where someone has passed in all their arguments as (mutable!) Maps, Collections and/or Arrays and "returned" values by mutating those structures knows what a nightmare it can be. Which I suppose is an argument that cuts both ways: on the one hand you can say: "why add Tuples which would be another easy thing to abuse", on the other: "why not add Tuples, given Arrays and the Collections framework already allow bad programmers to produce unmainable mush. One more feature isn't going to make a difference either way".
    Ho hum.

  • Bug? My events on the iPad iCal app aren't shown in the year view if they are more than two years in the future.

    My events on the iPad iCal app aren't shown in the year view if they are more than two years in the future even though I can see them on the month, week and day view. Any suggestions on how to fix it? I've tried it all. I called the apple support and they checked on their iPads. They all did the same and they couldn't help me. They suggested trying this way. I'd like to be able to plan a few years ahead and the year view would make thing so easy!
    Is this a bug?

    Go to the Home screen and double click the Home button. That will reveal the row of recently used apps at the bottom of the screen. Tap and hold on the app in question until it wiggles and displays a minus sign. Tap the minus sign to actually quit the app. Then tap anywhere on the screen above that bottom row to return the screen to normal. Then restart the app and see if it works normally.
    Then reboot your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.

  • HT4528 My IPhone Bugged out/It is currently in the reset mode. I need to exchange all of my contacts from my Yahoo acct. to my new IPHONE. Can you please help me?

    Hello ,
    I purchased my IPHONE about 2 months ago. I am visiting family in DE & this tuesday it starting to go off & on by itself. Then the icons looked like they were floating . Then I could not call or text . The SIRI device would not work. Then it would shut down then the apple icon would reappear. I took it to a verizon dealer in Rehoboth DE & they said it BUGGED OUT/It is in a RESTORE MODE. It will not turn on. We could not transfer anny of my pics or contacts. I never even had a chance to back up the memory on ITUNES.
    The tech @ Verizon said to contact APPLE to trouble shoot and try and transfer the contacts from my yahoo acct.
    Can you please help?
    Gina

    set up your yahoo account in mail, contacts, calendars as an Exchange Account and you should be able to get your contacts from Yahoo from there.
