invalid object reference

I have a reference to the overall purpose of the station. Is there a way to check if the object reference is valid?

Thank you.

  • Starling of null object reference

    This function is called in a loop for to create 4 buttons... Select the right image and display it.

    Problem is I get a null object reference in addChild line...

    I use Starling and I don't know how to get rid of this error. Can you help me?

    menuGroup [i] = newBtn;

    addChild (newBtn as DisplayObject); starling.display.DisplayObject

    newBtn.addEventListener (TouchEvent.TOUCH, Notecard, false, 0, true);

    {

    addChildAt (child, numChildren);

    }

    / * Adds a child to the container at a certain index. */

    public void addChildAt(child:DisplayObject,_index:int):void

    mChildren.splice (index, 0, children);

    child.setParent (this);

  • FlexContext.getFlexClient () returns an invalid object

    I have this Flex client application that I am trying to implement the logout function. This customer has HTTP and RTMP connections on the server. When the user press the logout button in the client, so I try to invalidate sessions HTTP and RTMP on MSDS so the FlexClient would become invalid.
    The behavior on the client, it's the login screen is displayed so that the user can connect again if they want. The problem is that if they do, the following happens on the side of the SDS:

    -connection through the HTTP channel will result in the call to FlexContext.getFlexClient () returns a new FlexClient object (which is correct), with the newly created flex Http session

    -aftarwards, try to connect via the RTMP channel, will result in FlexContext.getFlexClient () FlexClient object reference call to the former (i.e. those used on the previous session until the user pressed the disconnection), which is in an invalid State and has no session related. Everything would fail using this FlexClient. More, FlexContext.getFlexSession () returns the new RTMPFlexSession object (which is correct), but this session has no associated objects FlexClient (the getFlexClients() call returns an empty list)!

    My question is why the FDS who'd? Why FlexContext.getFlexClient () returns an old, invalid FlexClient object? It seems strange to me. I am using LiveCycle Data Services ES 2.5.1 on the backend, deployed on Tomcat 5.5

    Thank you.

    Not sure it's a bug or not. I'll discuss it with dev, but I agree with you invalidate the flexclient destroy also.

  • Access to the elements of an array passed as object reference

    Hi all!

    I am quite new to TestStand and therefore, my question might be simple enough but I was not able to find the solution by looking at previous posts.

    I have a sequence that passes a custom array (of data type) to another to make basic on the table stuff (reverse the order of the elements, for example).

    I want to move to the sequence called an object table reference

    The problem is that I am not able to read the array element inside the sequence called using the object reference.

    I found the way get the number of items, but I'm not able to access the item

    In addition, the TestStand GUI is able to let me see the array pointed to by the object reference that is passed within the known sequence, so it is possible to access... but how?

    I want to do operations on the object reference passed within a 'No return' TestStand if possible.

    Thank you very much.

    In other words:

    How do I access the field 'temperatureTag' item number '0' from the object variable reference referenceToClone?

    Locals.referenceToClone [0] .temperatureTag does not work...

    I don't know what is the recommended method to solve your problem. When you try to few alternatives, I was able to get the value required by the following expression (tested with TestStand 2014):

    Locals.referenceToClone.GetPropertyObject("[0]",_0).temperatureTag

    Try and tell me if it works for you.

    Use this workaround with caution.

  • find the memory leak when switching from Teststand object reference to vi

    I use Teststand to call labview vi and col ThisContext sequence to vi as object reference, but if I just completed this step and I can find the memory to help keep more, how can I avoid leaks memory inside the vi.

    See my vi, is displaying an interface message user.

    You should use a node reference close to close the references that you get after an invoke. In the code below, you should be able to close the references that you get the following:

    AsPropertyObject

    Thread

    Close these two references, once you're done with them.

    Also make sure you have turned off the collection of results of your sequence or you will use memory constantly to the results of the stage.

    Hope this helps,

  • the station's overall object references

    Are station global object references stored in a file as the globals other station? If so, how?

    The values of the attributes of the object can be recovered?

    Reference values are not preserved in the files. It is not technically possible in the general case, since a reference can point to any ActiveX object or .net.

    I get error "the server could not process the request. --> The object reference not set to an instance of an object"

    My code base to set up the soap request

    m_soap.setAction(hostServer + "/" + serverAction);
    m_soap.setHost(QUrl(hostServer).host());
    QtSoapMessage request;
    request.setMethod(QtSoapQName(serverAction, hostServer));
    
    request.addMethodArgument(new QtSoapSimpleType(QtSoapQName("AssociateEmail"),QString("[email protected]")));
    request.addMethodArgument(new QtSoapSimpleType(QtSoapQName("ShowName"),QString("print2013")));
    ....
    
    m_soap.submitRequest(request, endPointURI);
    

    I tried to addMethodArgument without the Type of SOAP

    That is to say.  request.addMethodArgument ("myParameter", "", "myValue");

    I tried to use a struct as shown in another post.

    QtSoapStruct* inputValues = new QtSoapStruct(QtSoapQName("Items"));
    request.addMethodArgument(inputValues);
    QtSoapStruct* item = new QtSoapStruct(QtSoapQName("Item"));
    item->insert(new QtSoapSimpleType(QtSoapQName("Name"), "_OS"));
    item->insert(new QtSoapSimpleType(QtSoapQName("Value"), "BB10"));
    inputValues->insert(item);
    

    It seems as if the arguments are not be attached to the request.

    I was getting an error that it lacked the required fields for the stored procedure.  So I adjusted the .net web service to set default values if the values sent via the web service were empty.  This moved me to the common mistake.

    So, apparently, it was matter of double.

    The first problem was in the client code:

    First of all, I needed to make sure that the parameters passed were in the correct order.

    Second, I found that the addMethodArgument was the right way

    request.addMethodArgument( new QtSoapSimpleType(QtSoapQName("AssociateEmail"), query.value(0).toString()));
    

    The second problem was with .net code.  I needed to make sure that the passed value is not zero.

    if (AssociateEmail == null || AssociateEmail == String.Empty || AssociateEmail.Trim().Length == 0)
                     { cmd.Parameters.Add(new SqlParameter("@IN_AssociateEmail", "No Associate Email")); }
                     else { cmd.Parameters.Add(new SqlParameter("@IN_AssociateEmail", AssociateEmail)); }
    

    And I had to make sure I have done this for each parameter.  Apparently, I sent a couple of empty values, and this caused the shot to the top.

    However, the return value is not always in the best format, but that's another thread.

    Found the solution (via the devgirl.org blog comments).  It turns out that this is a known problem in Flash Builder 4.6 with the TextInput skin.  Quick and simple solution is to add

    skinClass = "spark.skins.mobile.TextInputSkin"

    for the TextInput tag and everything works again (I heard him talk about a problem with StageText and as you can see, which appears in the stack trace I became).

    Also became strangeness when exporting for Android (entries endangered and appear outside the textinput).  I hope this will fix this problem too.
