DisclosureListener of af:showDetailItem Invoking Method Twice
Hi All,
I am using Jdeveloper Studio Edition Version 11.1.2.1.0.
I have a af:panelAccordion, generating af:showDetailItem at runtime using af:forEach component from a view. The code snippet is given below:
<af:panelAccordion id="pa1" partialTriggers="np1" discloseMany="false" discloseNone="false">
<af:forEach items="#{bindings.VerticalAppMenus.children}" var="globalMenu" varStatus="globalMenuVarStatus">
<af:showDetailItem text="#{globalMenu.MenuLabel}" id="sdi1" disclosureListener="#{pageFlowScope.globalMenus.refreshLineMenus}">
<f:attribute name="currentVerticalMenuId" value="#{globalMenu.MenuId}"/>
<af:tree value="#{bindings.LineAppMenus.treeModel}" var="node"
selectionListener="#{bindings.LineAppMenus.treeModel.makeCurrent}"
rowSelection="single" id="t1">
<f:facet name="nodeStamp">
<af:outputText value="#{node}" id="ot1"/>
</f:facet>
</af:tree>
</af:showDetailItem>
</af:forEach>
</af:panelAccordion>Every af:showDetailItem is assigned an Id through f:attribute which is passed to method refreshLineMenus pointed by disclosureListener property. Assume af:showDetailItem with Id=2 is currently disclosed and I click on af:showDetailItem with Id=4 to disclose it. The method pointed by disclosureListener is getting invoked twice, initially with value 4 and then 2. Ideally it shall be invoked with a value 4 only as the item which is disclosed has the Id=4.
Is it the default behaviour for the disclosureListener to invoke the method twice; means once for the disclosed and once for the concealed af:showDetailItem? If yes, then how can I executed a method once on disclosure of showDetailItem in the above code?
Any help will be highly appreciated.
Thanks ... Best Regards
Bilal
Hi,
yes there will be 2 invocations...
one for the older one and one for new one..
so there will be 2 invocations but no 2 requests, you can easily know the current selected tab by DisclosureEvent.isExpanded()
which will return whether current item is expanded or not...

Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi
Hey there,
we have sensors on an Engine which are connected to a NI cRIO 9014 board (with a NI9411 6-channel digital input modul) and go from there via network to a host computer.
cRIO board: the cRIO board collects the data from the engine and stores it in a buffer, this is because the network is to slow for the magnitude of data
host computer: the host computer reads over the network the buffer on the cRIO board, on the host computer it takes out specific portions of the data to create pressure graphs of the engine
Error:
Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi
Possible reason(s):
The transfer did not complete within the timeout period or within the specified number of retries.
This error occurs in the following scenario:
- engine is running
- cRIO is running
When I press the start button (boolean 3) in the host.VI to start the reading of the data from the board AFTER I pressed the run button of the host VI.
The Error would not occur if I pressed the start button (boolean 3) BEFORE I pressed the run button of the host VI.
We tried to increase the time out, but it still did not work, the error occurs!
We would be really happy if you could look over it and help us in this case! If you need further informations or if we need to clarify some specific portion, please let us know!
We included the VI's in the attachement!
Thanks in advance!
Solved!

Cyl_Pres.lvproj 196 KBChrisse,
There are a few things wrong in your application, if I may offer some suggestions.
First, your while loops are not running in parallel. In fact, they are in while loops with a true constant wired to them. I am not sure if this is by design for debugging, or on accident. I would put the Polling(read pulling zero elements) outside your main while loop.
Your second nested while loop (the one polling the # of elements and then pulling them out) is going to run just once, and may pull only a few samples. I don't think that is what you are looking for here, and there are a couple ways we can go here. You could continuously poll until you have 0 elements available for x amount of time, then you know you have no more samples available and you can process all the data OR you can put all of your data processing as part of that loop and just always write to file immediately as x samples are pulled.
Also, your main loop's stop condition is (i <= 3) Therefore, it will run once and then stop. Maybe you mean >=3?
Also, you have 'append to file' disabled on your write to spreadsheet, so everytime you write you are overwriting old data. If you want to continuously write, you will be losing data. This can be cured by either setting this to true(requiring a new file name or programatically deleting the old spreadsheet every time you run the vi) OR you can collect all of your data in a shift register, and only write to file once you have all your data available.
The error you are seeing is because you try to close your FPGA reference twice. You only need to close it once.
After seeing your overall picture, I think this can all be cured by simply hardwiring your Read to get your 1440X4 elements, but as we have seen, this does not work. Something is happening in your system....this is what I want you to do...run just the following code...and let me know how many elements remaining it gives you...Once the number has settled(I hope it does and your engine doesn't keep running), hit stop, and all the values will be put on a graph for you. My broken wires are because I do not have the FPGA VI.

Edited by: 911694 on Jun 25, 2012 1:02 PMThis is a very convinient feature of Weblogic startup service - if your class
does not implement T3StartupDef it will look for (using introspection)
public static void main(String[] args) in your startup class, and, if it is
there it will execute it.
Ricky Wong <[email protected]> wrote:
It works, many thanks !
However I still have one more question out of my head - I found that my
startup class doesn't need to implement the T3StartupDef and it still
works, however my shutdown class must implement the T3ShutdownDef
(otherwise I'll get ClassCastException).
In article <[email protected]>, [email protected] says...
Most likely the HubDevicePool does not have a public default constructor.

I'm pretty sure that the class HubDevicePool has been coded (e.g.
implement T3xxxDef interface, with either the startup() or shutdown()
method) properly as I've another startup classes which work perfectly.
The class has been compiled without error, but it just cannot run when I
put it as either a startup or shutdown class for WebLogic.Dimitri

Invoke Method: Run VI produces error when run as an application
Hello,
I have upgraded from LabView 7.0 to 2009. One test program uses Run VI Invoke Method to start the main UI. On LabView 7.0 it works OK , when build as an application, but with LabView 2009 it gives error 1003: Invoke Node xxx.vi <APPEND> VI Path: xxx. (I have checked that the path to "Open VI Reference" is correct.)
When run on LabView 2009 development environment (.vi) - no problem. I used the "Convert built script.." tool to convert to LabView 2009 built specifications. I have tried numerous different variations building application with LabView 2009 (including main UI files, different setups, etc.), but no luck. If someone has any ideas...
-timoMaybe it helps you for debugging:
I checked the property for the broken arrow. You need a property node and go Select Class 'Vi Server'->'VI' (skip this in your Application but navigate to the VI via the server and feed it to the node). Then it is Execution->State.
I need to draw some code to do it for me as well, once I'm done I'll post it here.

<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: Cannot invoke method multiply() on null object
any help please ?Thanks Frank ,
really i've already downloaded the ZIP of the final application , but the same error message ,
when removing the Annual salary ( Which is a new Attribute ( not DB column) Salary * 12 ) every think is fine and no more error message ,there is no null salary all the employees have a salary , my JDeveloper Version is 11.1.2.1.0
also , because of the EmpDetails is based on the query
FROM EMPLOYEES Employees, DEPARTMENTS Departments
WHERE Employees.DEPARTMENT_ID = Departments.DEPARTMENT_ID
and the Department id is non editable value , that means even if you add a new user u cant never check this user in this interface , u can check this user only on DB (SQL) level .

Invoking methods via java.lang.Method.invoke().

How can I invoke the getter methods of the trade object.

Running a vi using run vi invoke method
Hello,
I have a question about the run vi invoke method.
I have a start vi and a stop vi. When I run the start vi, it uses the run vi invoke method to call a third vi. I want the third vi to run until I call the stop vi which sets a global causing the third vi to stop. Now this seems to work ok when I have the third vi open. But if the third vi is not open, it will stop running when the start vi stops. Is there any way to make it run past the execution time of the start vi without having it open?
Thanks for any help!The attached VIs (LV v7.1.1) will do what you describe.

Dynamically invoke methods of abstract class?
Hi,
I am using reflection to write a class (ClassA) to dynamically invoke methods of classes. I have an abstract class (ClassB) that has some of the methods already implemented, and some of the methods that are declared abstract. Is there any way that I can:
(a) invoke the methods that are already implemented in ClassB;
(b) I have another class (ClassC) that extends ClassB, some of the methods are declared in both classes. Can I dynamically invoke these methods from ClassB?
Thanks in advance,
Matt.Ok, the program is quite long, as it does other things as well, so I'll just put in the relevant bits.
What I have is a JTree that displays classes selected by the user from a JFileChooser, and their methods.
// I declare a variable called executeMethod
private static Method executeMethod;
// objectClass is a class that has been chosen by the user. I create a new instance of this class to execute the methods.
Object createdObject = objectClass.newInstance();
// methodName is the method selected by the user. objectClassMethods is an array containing all the methods in the chosen class.
executeMethod = objectClassMethods[j].getDeclaringClass().getMethod(methodName, null);
Object executeObject = executeMethod.invoke(createdObject, new Object[]{});Ok, here are the test classes:
public abstract class ClassB{
private int age;
private String name;
public ClassB(){ age = 1; name="Me";}
public int getAge(){ return age; }
public String getName(){ return name; }
public void PrintAge(){System.out.println(age);}
public void PrintName(){System.out.println(name);}
public abstract void PrintGreeting();
public class ClassC extends ClassB{
public ClassC(){super();}
public void PrintAge(){
System.out.println("I am " + getAge() + " years old.");
public void PrintGreeting(){
System.out.println("Hello");
}Now, I can print out the PrintAge method from ClassC (i.e. have it output "Hello" to the command line, how can I, say, get it to output the result of PrintName from ClassB, this method does not appear in ClassC. As you can see at the top, I can create a new instance of a normal method (in this case, ClassC), and have it output to the command line, but I know that I can't create a new instance of an abstract class. And since PrintName is implemented in abstract class ClassB, how do I get it to output to the command line?
Thanks,
Matt. -
Why does SunOne 6.1 call servlet init() method twice on startup
Hi,
SunOne6.1 sp 5 is running my servlet's init() method twice when I put load-on-startup in the web-xml file. Is this a known problem and is there a work around as no amount of synchronising seems to work.
I'm running 2.3.dtd for the default_web.xml file and my entries look like this :-
<servlet>
<servlet-name>RelatisLogin</servlet-name>
<servlet-class>com.MyServlet</servlet-class>
<load-on-startup>7</load-on-startup>
</servlet>
This init method only contains a basic check at the moment :-
public void init()
System.out.println("init.....");
If I take <load-on-startup> away and run the server then call the servlet via the url it only runs init once.
I've tried synchronizing the block but this doesn't work.
The synchonization code I used looks like this:-
public void init(ServletConfig config) throws ServletException
synchronized( AnotherClass.staticString )
if ( AnotherClass.staticString.length() > 0 ) return;
System.out.println( AnotherClass.staticString.length() );
AnotherClass.staticString = "init has been called";
try
int i = 0;
i = i/i;
} catch(Exception e)
e.printStackTrace();
The declaration of "AnotherClass.staticString" is :-
public static String staticString = "";
The output of "System.out.println( AnotherClass.staticString.length() );" is 0 and displayed twice.
I deliberately cause a divide by zero error to get a stack trace so that i can determine what called init(), the stack trace is printed twice and is always :-
java.lang.ArithmeticException: / by zero

It looks like SunOne starts then calls init() and then restarts and calls init() again.
The same code and same web.xml entries work fine in Tomcat 5, init() only every gets called once.
Any ideas? Can I post this as a bug?
Thanks in advance for any help.
Chris.Sorry to have not replied to this thread earlier.....forgot all about it.
The reason init was being called twice by IPanet (Sun One) is IPanet comes with a default context called "Search" already in server.xml file.
This context was loading all the classes on my class path and this causing "init" to run. Then my context entry also loaded all the files in the class path.
Quite why Sun include this "Search" context is beyond me......annoying. If you take it out the the problem goes away.
Basically if you leave this in then your running to web servers (JVM's) your one and Sun's stupid "Search" one. As they are separate JVM's no amount of synchronisation would ever fix it. -
Invoking methods in C++ from Java
I'm invoking the Java Virtual Machine from my C++ program like is described here: http://java.sun.com/docs/books/tutorial/native1.1/invoking/invo.html
So, I run my C++ program (let's call it C), C invokes the JVM and starts a Java program (let's call it J). C can now invoke methods in J. Now I want J to invoke a method in C. Is this possible?Yes it is.
However your C code that you want to invoke from java must be defined as "native" - that is, it is defined as the implementation for java methods that are declared native.
The possibly most confusing part is where to put the C code and how to make the java-C linkage.
o You can put the C code in a DLL, and use a "loadLibrary" call to make it available.
o Alternatively, and perhaps more likely, your original C/C++program can make "registerNative" calls to the JVM to identify to it the native implementations. -

Pass control references to subVI using Invoke Method
Hi guys,
Can I use <Control Value Set invoke method> to pass some control references to a sub VI, then use the <Run VI invoke method> to run the sub VI with the previously passed data? The control refnums are for some frontpanel controls in the Main VI.
I was able to pass other data but the refnum didn’t work.
ThanksHi there, There are a couple examples that use the same method. Check them here:
- Set Control Values and Trigger UI Events in Another VI
- Set Values and Properties of Controls in a SubVI
- Save and retrieve front panel control values

Error 1026 invalid reference at runVI invoke method in main exe- subVI- subpanel
Hello,
I have a main VI which have subVI's inside case structures set up to show FP when called and be modal.
These subVIs have a subpanel that will pull up a dynamicVI using RunVI invoke method.The dymaicVIs path is built using application directory constant+the VI name to the invoke method.
now the main VI is built into exe with the dynamicVIs in always included list.
when i run the main exe i am getting 1026 error VI reference invalid.
Plz help
Thanks
Solved!
Go to Solution.Hi Freemason,
The problem could be coming from the use of relative paths, because the path can sometimes change when building an application. Double check to make sure they are calling the right path. You can also try changing the AutoDispose Refnum in your run VI invoke node to false. It is one of the methods you can select in your run VI invoke node. If neither of these solutions work, run your code using the highlight execution function. If you implemented error handling in your program, you should be able to see the source of the error.
If you’re still having issues, could you post some screenshots or your actual VI? I may be able to get a better idea of the issue that way. I’ve also attached an example VI that uses multiple subVIs and a subpanel for reference. Hope this helps.
