Problems unloading modules (due to skins?)

Hi,
I have a problem in my Flex application where modules are not unloading. I moved the focus out, cleared out eventlisteners (I read diff. tutorials on that) and now modules are not increasing every time I load them but there is still always 1 instance of the module that has been loaded.
Suppose we have a login module, if I would open it 5 times I would have 5 references in memory, now only 1 which is good, but when the module is not open it needs to be 0 and not 1. When I use the profiler I get 10 paths (this means references still in memory for the login module, right?) to the login module as displayed in the screenshot
It seems to be an issue in the skins or how should I see this? Is it because the skins are used somewhere else in my app also? Can anyone shed some light on this?
Thanks

Which version of flex?

Problems unloading Module

So we have a project that has two states a 'Welcome' state and a 'Module' state.
We have two types of modules. One module is of type TestLab which is a component we've created. The other type of module is a blank view that will show popups as they're called.
The problem we're having is very strange and hard to pin-point.
If we load TestLab A, then unload TestLab A, load TestLab B, unload TestLab B, load TestLab A......all the modules are cleaned up properly.
But if we go from TestLab A, to welcome screen, back to TestLab A....TestLab A will not have unloaded the first time and we'll have double modules, although we're calling the exact same code to unload and load the module.
It's also the same thing if we go from TestLab A -> other module - > TestLab A.
Although if we go to TestLab A -> welcome -> TestLabB -> TestLab A, everything is cleaned up properly.
So it appears in order for a module to be properly unloaded and released from memory, we must load a different module of about the same size.
Anyone have any idea what may be the culprit. It's just very strange to me that modules can be unloaded and released sometimes, while other times they hang in memory depending on what module was loaded after it.

Unfortunately, that isn't my area. I would ask on the FlashBuilder forum.
Did you verify that the preloadSWF entry in mm.cfg looks the same when it
works profiling a simple app?
Also, when you're not attempting to profile, there shouldn't be a preloadSWF
entry in there. Sometimes FB fails to remove that entry so deleting it
might help. FB will re-add the preloadSWF entry as needed.
Another thing to look into is FlashPlayer Trust files. They should be set
up automatically by FB, but occasionally an custom configuration fools the
setup. They are stored in different places based on your OS. Search the
Adobe site for details on where they go. They are typically used to get rid
of security errors when running apps from file://

Problem in Module processor

Hi All,
can any body help me on this
how much time will take the module processor to execute the message.
If 4/5 messages are entering into MP at the same time what will happened
I am getting the error in this stage when iam using receiver FILE Adapter
getting the error log " Message is entering into the Module Processor"
then in the next log i will be getting the following error differently
Attempt to process file failed with
com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution:
com.sap.aii.adapter.file.varsubst.VariableDataSourceException: Caught SAXException while parsing XML payload:Fatal Error:com.sap.engine.lib.xml.parser.parserException: XMLparser: No data allowed here(:main:,row:,col:75)"

for the same message when the sys tried to resend
parserException:start-tag 'EIT' is different from the end-tag'E1EDP03(:main:,row:1,col:16)
but there is no problem with payload also

Hi All,
1.I am not using custom Module, it is IDOC to File Scenarion.
2.No Content Conversion.
3.There is no problem with Mapping.
Maximum Messages are successfull, some messages are failed in the Module due to this error.
Every message (main:, row:1:,col:1923) this will be changing and some times </ expected, Document is not well-formed, No data allowed here "
"If i rescend the message 1 by 1 message is processing successfully, but if select more than 1 message only one message getting processed".
Around 4 interfaces with this type of error, but all having same problem some messages are failed with this kind of error.
If more messages are attempting to process at the same time in the module processor is there any loading problem that causes this error?.
Thanks & Regards
Sankar

[solved] Unloading modules before suspend to disk

Hi, I'm trying to get my Asus U36jc to suspend to disk and resume. Suspending seems to go fine, but after resuming I get an unresponsive notebook (no response on key presses or ping) showing a black screen. Then immediately the fan gets louder and the notebook gets warmer.
Just before the machine goes to sleep, I see this in my screen:
xhci_hcd 0000:04:00.0: PCI post-resume error -110!
xhci_hcd 0000:04:00.0: HC died; cleaning up
xhci_hcd 0000:04:00.0: HC died; cleaning up
dpm_run_callback(): pci_pm_resume+0x0/0xb0 returns -110
PM: Device 0000:04:00.0 failed to resume async: error -110
hda-codec: out of range cmd 0:20:400:fffff7ff
I found this guide (https://www.kernel.org/doc/Documentatio … ugging.txt) and using that I determined that when I first remove modules ehci_pci, ehci_hcd and xhci_hcd, suspend to disk and resume seem to work fine.
I found out here (https://wiki.archlinux.org/index.php/Pm … end_to_RAM) how to unload modules prior to suspending to RAM, but that doesn't seem to work for suspend to disk, and I can't find how to unload modules prior to that. Can someone tell me how to do that?
Thanks for any help!

I'm not sure if pm-utils is deprecated, it doesn't say so here (https://wiki.archlinux.org/index.php/Pm-utils). In any case its a dependency of upower, which is a dependency of kdelibs, so as long as I want to use KDE my harddrive is stuck with it.
However, I decided to try your suggestion to use systemd:
# asus36JC.service
[Unit]
Description=Script upon suspend/resume
Before=sleep.target
StopWhenUnneeded=no
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/home/diederick/bin/no_modules
ExecStop=/home/diederick/bin/modules
[Install]
WantedBy=sleep.target
It seemed to work perfectly for a couple of times in a row (modules were there before and afterwards) until I restarted the notebook, when the problem was back. But then I remembered to enable the service and now it works. Thanks a lot!

Problem with modules and ModuleLoader

Hi everybody,
i'm facing a real funny problem with modules and
moduleLoader, i hope
it's not (only) my fault anyway...
If i create a normal flex project with fBuilder, i'm able to
use
modules in a lot of different ways (as mxml, as as in a
function etc..)...
but if i try to use them in my fds application (created with
fds
eclipse plugin or as a dataServices project) i can't use
modules. The compile-time error message is
always the same:
Could not resolve <mx:ModuleLoader> to a component
implementation
I tried a lot of solutions, paying attention to import all
the classes, to declaration, naming, positioning
etc...but nothing changes, this thing is drivining me
crazy!!!.
I will appreciate anykind of help.
TIA
Fabio

Any idea?

Problem with module lazy loading in flex 3

Hi every body!
I have some problems with Module lazy loading. I am using flex 3.5, Module-flex3-0.14, parsley 3.2.
I can't get the LazyModuleLoadPolicy working correctly.
In my main application (the one that loads the modules), my parsley context is the following:
        <cairngorm:LazyModuleLoadPolicy objectId="lazyLoadPolicy" type="{ OpenViewMessage }" />
     <cairngorm:ModuleMessageInterceptor type="{ OpenViewMessage }"/>
     <cairngorm:ParsleyModuleDescriptor objectId="test"
          url="TestModule.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
And to load my module:
[Inject(id="test")]
[Bindable] public var test:IModuleManager;
<core:LazyModulePod
     id="moduleLoader"
     moduleManager="{test}"
     moduleId="testModule"
/>
with LazyModulePod.mxml:

            return _viewId;
        [ModuleId]
        public function get moduleId():String
            return _moduleId;
In another flex project, my module context is:

The module implements IParsleyModule

     public function WindowControler(){}
     [Init]
        public function initialize():void
            Alert.show("Module Initialized");
        [MessageHandler(scope="local")]
        public function openViewMessageHandler(message:OpenViewMessage):void
            Alert.show("Opening view " + message.viewId + " in the module " + message.moduleId);
If i uncomment the basicLoadPolicy in LazyModulePod.mxml and remove the lazyModuleLoadPolicy, everything works fine. The module is loaded when it's added to stage and it receives correctly messages dispatched to it. But with the lazy policy the module never loads.
I may have missed something or there is somthing i don't understand because i tried the ModuleTest provided in example in cairngorm sources. It works fine (i mean loading the moduleA2 when receiving a message), but if i replace the change the lazyModulePolicy to listen to broadcasted messages instead of a pingMessage, the module never loads too.
    <cairngorm:LazyModuleLoadPolicy objectId="lazyLoadPolicy" type="{ BroadcastMessage }" />
    <cairngorm:ModuleMessageInterceptor
        type="{ BroadcastMessage }" moduleRef="moduleA" />
public class BroadcastMessage
    public function BroadcastMessage()
If someone has any clue, i'll be happy to test it =)
Thanks.

Hello, back on my issue, i tested a little bit more the message dispaching.
I read the lazyLoadPolicy class and noticed that it always has to have a ModuleId property in the message to work, that's why the broadcast message didn't work to awake the module with the lazy loading policy.
So i added copy of my module:
     <cairngorm:ParsleyModuleDescriptor objectId="test"
          url="TestModule.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
     <cairngorm:ParsleyModuleDescriptor objectId="testbis"
          url="TestModuleBis.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
Set them both with a basicLoadPolicy, and tries to dispatch a message to only one of them using the ModuleId metatag. I then noticed that both modules received the message and not only the one i expected.
I then changed the ModuleMessageInterceptor configuration to dispatch to only one kind of module:
<cairngorm:ModuleMessageInterceptor type="{ OpenViewMessage }" moduleRef="test"/>
and this worked as expected. Only the first module catched the message. I am obiously messing with the ModuleId metatag but i cannot see what's wrong...
I compiled with
-keep-as3-metadata+=ModuleId
but this hasn't changed anything...

JBO-30003: The application pool failed to checkout an application module due to the following exception

We have developed an ADF application using 11.1.2.1.0 version. We get the following error in production environment as about 3 to 4 times in a week as an error and as warning many times per day. The warning does not come to the screen or not shown to the user but the errors are shown to the user as a pop-up with 'java.lang.NullPointerException' message.

If it helps, the following are some settings of the application module.
We are using locking mode as 'pessimistic'. The production environment is not a cluster environment. These are the settings for passsivation:
jbo.dofailover=false

I also tested by running the application module seperately, it works fine.
Please help us to solve this issue...

Hi Chris,

Unloading modules in ubuntu

Hi,
How can I unload modules in ubunt (e.g., graphics module, keyboard, USB etc)?

Unloading Modules in Flex

What does the debug trace [Unload SWF] mean?
As per this blog
http://blogs.adobe.com/tomsugden/2010/02/how_to_unload_modules_effectively.html
"This trace indicates that the module have been successfully unloaded"
Is this true?
I am unloading a module, I see the [Unload SWF] trace, but after unloading, if I try to create an object of a class contained in the unloaded module (using reflection), I am still able to create it.
Am I understanding it wrong?
Thanks!

That means that the bytes of the SWF have been removed from memory. I'm not
sure if you're just getting lucky or if there is some other thing going on.
Post a simple test case.

Problem compiling module with named package

Hi,
I'm relatively new to Flex and only recently came upon Flex modules. I am trying to use an interface between the modules and my main application, both to enforce compatibility and to ease data access from the modules to the main application (i.e., the preferred approach on Adobe's module implementation docs). I am, however, running into a problem when trying to compile the module (using Ant) due to its implementation of an interface in a named package. It seems I have a choice between two compilation errors:
1) an error referring to difference between the named package structure and the unnamed package for my module
2) an interface not found error when I specify the full package name for the interface in the module "implements" attribute
#2 seemed more promising as I figured this was just some sort of source path error. After adjusting the source path many times, though, I have been unable to get past the interface not found error. I even tried to compile the interface into a SWC and then place the SWC on the library path.
Overall, the structure of the code is very simple:
com.example.workers.IModule
WorkerModule1
If I go ahead and make IModule part of an unnamed package, I can get past problem #1 (avoid #2) and get it to compile, but then I do not have the ability to cast the child of the loaded module (ModuleLoader.child) to the interface in my main application to insure that it is of the right type (though I can hack around this by checking if the child has a certain property or function).
Anyway, I am guessing that there might be something simple that I am missing here--i.e., some way to get the named package onto the path for my mxmlc-based compilation of the module or some way to add the named package structure to my module (adding an xmlns did not accomplish anything). In any case, any help here would be greatly appreciated.
--jonathan

You definitely have the wrong version. You want 2.0.1 (we
haven't made a 2.1). The download on the Flex page is always the
most current version, 2.0.1 in this case. Try it again.

[solved] unload module alx on suspend fails

Hi!
I'm having trouble getting my ethernet card to work properly with suspend to ram (pm-suspend). Its a Qualcomm Atheros AR8161 Gigabit Ethernet Adapter (builtin ethernet-card of the Asus N56VZ) that I'm running with the alx-module that I build from the compat-drivers (compat-drivers-3.9-rc2-2-su, so version 1.2.3 of the alx module) on kernel 3.8.8-2. The driver works fine except it breaks suspend. A first suspend works fine (see suspend.log, upper part), however, after resuming, NetworkManager does not detect a cable being plugged in. Trying to suspend again fails results in the lower part of suspend.log. Removing and probing the module again (reload.log) seems to work fine and resets the whole thing (network works, one suspend works, all following do not work)
Logs see https://gist.github.com/anonymous/5467609
I created a file SUSPEND_MODULES="alx" /etc/pm/config.d/modules (rights 644) that as far as I understand is supposed to unload and load the module upon suspend and resume but for some reason this does not seem to work properly. Why is that, am I just missing a typo? How can I fix it?
Any help is appreciated!
Hannes

„Sleep hooks
Systemd does not use pm-utils to put the machine to sleep when using systemctl suspend, systemctl hibernate or systemctl hybrid-sleep; pm-utils hooks, including any custom hooks, will not be run. However, systemd provides two similar mechanisms to run custom scripts on these events.” – from wiki, so the sad thing is it's not as easy as in Ubuntu.
But (I guess) it's not impossible. I've got the same problem with ALX so I'm gonna try to make my own hook based on Wiki tips. Currently this Wiki page https://wiki.archlinux.org/index.php/Pm-utilspm is outdated (for Systemd user), so I'll try this section https://wiki.archlinux.org/index.php/Sy … management .

Load/unload modules automatically

Hello guys,
to be able to eject a disk after pressing the eject-button of my cd/dvd drive I have to unload/load the modules manually with the following commands:
rmmod sr_mod
rmmod cdrom
modprobe cdrom lockdoor=0
modprobe sr_mod
After that I can eject it without any problems. I thought I can automatise this by adding options cdrom lockdoor=0 to /etc/modprobe.d/modprobe.conf and finally load the modules in my /etc/rc.conf like the following:
MODULES=([...] "cdrom lockdoor=0" sr_mod)
But it still doesn't work. What's wrong?
Thank you in advance.
