Nested Subpanels for LVOOP Class Hierarchy

Hi,
I am trying to figure out a way to create a configuration window for a class object using a subpanel. The problem is that I have LVOOP class hierarchy of 3 levels, and thus I want to use nested subpanels, one subpanel for each inheritance.
For example,
A.lvclass (abstract class)
Private Data Members
String A
Configuration Window VI ( Within a FP there is a String A control and a subpanel for its child class)
B.lvclass (abstract class) (child of A.lvclass)
Private Data Members
Boolean A
Boolean B
Configuration Window VI (Within the FP there is a Boolean A control and a Boolean B control, plus a subpanel for its child class)
C1.lvclass (concrete class) (child of B.lvclass)
Private Data Members
File Path A
Configuration Window VI (Within the FP there is a File Path A control)
C2.lvclass (concrete class) (child of B.lvclass)
Private Data Members
Boolean C
Configuration Window VI (Within the FP there is a Boolean C control)
What I am trying to accomplish is to create configuration windows for C1 and C2. For each configration window, there are sections for class A and class B, and for the class itself. However, I do not want to recreate the same section (for A and B) over and over again each time new children (siblings of C1) are introduced. To avoid this duplicate task, I think using nested supanes makes sense. But I don't know the best way to do it. Any advice is appreciated
Thank you

Need a link for ADF class hierarchy diagrams

Hi,
For some reasons i m not able to find via google or in documentation I need class hierarchy diagrams of the following
- ADF Binding e.g Faces* to AttributeBinding etc etc.
- ADF Model e.g ApplicationModule > Entity > View to Rowset etc etc
these diagrams frequently used by Frank Nimphius in his presentations.
Best Regards,
Zeeshan Baig

Hi,
I created the binding diagram using Oracle JDeveloper class diagrammer. You don't need the source code for this. Create a new class diagram in JDeveloper, use right mouse context menu and choose "Add to diagram". Browse the class path to the classes you want to see (e.g. adf | model | binding) and select them. It takes a few seconds for the diagrammer to layout the classes, but then you have the diagram you are looking for.

Regarding BAPI for Creat Class Hierarchy

Hi ,
Urgently i need a BAPI for to create Class_Hierarchy and also need what are the parameters to pass for that BAPI .
Please any body help out this is urgent.
thanks in advance,
krishna.

Hi,
The relavant BAPI is BAPI_OBJCL_CREATE.
You can read the characteristics by using BAPI: BAPI_OBJCL_GETDETAIL
Plz check other BAPIs in FuGr: CLBPA which might help you. You can find FM Documentation for most of the BAPIs in this FuGr.
If this is a one time load, I suggest you to take up this task by LSMW:
Object               0130   Classification
Method               0001   Batch input
Program name         RCCLBI02
Program type         B   Batch input
Hope this helps.

Is it possible to increase the timeout on the properties dialog for LVOOP classes ?

I'm working on a medium scale application which has a lot of claases in it (it's got several largish Actor Framework based modules with quite a few possible messages). Recently it's gotten to the point that when I right click on a class to bring up the properties dialog, the dialog seems to take so long figuring out my class heirarchy that it times out and gives me the attached error.
I don't suppose there's any way of increasing the time out on the dialog ? (I suspect the fact that my laptop's hard disc speed has been crippled by my IT services encrypting it isn't helping me here...)

Here is the modified VI, saved in LabVIEW 2012. Follow these steps to patch your system:
1. Close LabVIEW 2012.
2. Backup the following file: LabVIEW 2012\resource\Framework\Providers\VILibrary\libFrame_OpenPageRef.vi
3. Replace it with the version attached to this post.
4. Restart LabVIEW 2012.
Now you should no longer experience the 30 second timeout when the class property page loads. I set the timeout to "-1", so it should wait as long as necessary to open the page.
Note that if you ever repair or reinstall LabVIEW 2012, you'll need to patch this file again. Also, I wouldn't try patching any version other than 2012, since there may be other changes made to this VI across LabVIEW upgrades.

Change LVOOP Class Icon Color on All Members

I have a LVOOP class hierarchy (LV2009) composed of several classes that when created I used the default randomly selected color for each class. For each class I have developed several member elements (VIs, Ctls, etc), and now I have decided on a color scheme I would like to adopt. Changing the color on the template icon from the class properties will allow me to propagate those changes to the class member VI icons but it does not seem to have an impact on the class control icons on each of the member VI front panels. The class data member control has the cube with the original color. I like the idea of keeping the standard cube glyph, but changing the cube color and shading pixel by pixel is not appealing.
Is there an easy way to change the color scheme of an entire class that will update the color on the VI member Icons, the data member control and all instances of the control?
Is there an easy way to change the color of the standard cube glyph that is used by default on data member controls?
Is the cube glyph in a glyph library somewhere?

Justin_P wrote:
There is not a way to associate the color of the cube glyph (class data member control icon) with the color of the class template. If I had just a couple classes I would just change them manually. If I had a whole lot of classes, I would probably draw the cube in another program (that would do the shading automatically) and turn the image into a glyph that you could use in the icon editor.
I have attached a psd file (inside the zip) that will allow you to shade any color cube for this glyph creation. Simply change the color in the "Color" layer and the shading will apply automatically. Please note, you will need to flatten all the layers before you can copy and paste this into labview.

Search for Objects via Class Hierarchy

Dear colleagues,
For searching of an Object via a Class Hierarchy, Program SAPLCLSD screen 1000 release 4.7, a double click is required on the Class (left side of the screen) from which you want to see the Objects. If you do not click double, the view of the related Objects will not be recreated.
Is it possible to avoid the double clicking?

Hello Alpesh,
Thank you for your response. The user asked whether the double click, needed for the show of the objects, related to a Class, can be done with a single click.
They use transaction CL20N, input Class type, search for material with F4 search by Class input of a Class, then a tree of Classes will be shown. Select a Class, use button 'Include subordinate classes' and, if available, the related object(s) are shown.
The issue is that when you select another Class, you have to double click on the selected Class to make the screen with Objects empty.
Can we change the double click easy to a single click?
Kind regards, Jan van der Veen. 06-22973646 Netherlands.

Lots of problems building a large executable with LVOOP classes

I have a large project that makes significant use of LVOOP. It is essentially a test executive that sequences lots of different types of tests in a configurable way. I used to use a ton of variants in and out of these tests so they could be used interchangably in the archetecture of my application, but when LVOOP came out I rewrote my test executive to us an LVOOP class called "GTSTest". Then I have about 10 sub-classes that inherit from the "Test" class. Each of those sub classes are the actual specific tests. Here is a shot of the project:
You can see I am creating a main class called "GTSTest" and that gives me polymorphism of any specific kind of test like "Torque Center.lvclass" and "AutoLinearize.lvclass". It works fantastic in the development environment.
My problem now is I can't build anything with any of the LVOOP stuff into an executable. I originally added all the classes as dynamic vi's because some of them pop up their front panels. An application engineer suggested taking them out of the dynamic vi's section, but that didn't make any difference. Here is the error I am getting:
TestExec Build error:

Autolinearize.ctl is the alphebetical first class's private data definition. So what's going on? I made all the classes dynamic and it gives me the error. I made none of the classes dynamic and it gives me the error. But actually I know I'm going to need at least some methods of all the classes dynamic because a couple of the methods get subpanelled in the program so I need the front panels.
I've searched everywhere and I see no documentation at all about how to build LVOOP into an executable. But clearly you need to do something special for this to work. Can anyone help me?

I got 99 problems but 8.6 ain't one.

OK I figured out what is going on.
RULES FOR CREATING EXE’S WITH LVOOP
1. Do not put any lvclass or any “dynamic vi” of any lvclass in the “Dynamic vi’s and Support Files” section of the source files tab in the build window. Yes I know they are called “dynamic vi’s” in the LVOOP structure and one would assume you may need the front panels etc., but somehow they get loaded in automatically and if you explicitly include them as dynamic vi’s I think they conflict with themselves somehow. If you do this you will get the following error:
Error 13 occurred at Invoke Node in ABAPI Dist read linkages.vi->ABAPI Dist Cmp Settings to Disk Hier.vi->ABAPI Get Settings From File2.vi->EBEP_Invoke_Build_Engine.vi->EBUIP_Build_Invoke.vi->EBUIP_Build_Rule_Editor.vi->EBUIP_CreateNewWizard_Invoke.vi->EBUIP_CreateNewWizard_Invoke.vi.ProxyCaller
Possible reason(s):
LabVIEW: File is not a resource file.
=========================
NI-488: Sharable board exclusively owned.
Method Name: Linker:Read Info From File
O:\Software\MfgTest\Galvo Test Station (GTS)\Classes\Tests\Auto-Linearize\AutoLinearize.lvclass\AutoLinearize.ctl
In this case “Autolinearize.ctl” is the first class definition in the build.
2. In the additional Exclusions section, you cannot use the “Remove as much as possible” option. This disconnects typedef definitions, and I think it is misinterpreting lvclasses and trying to disconnect the class definitions, which breaks the application. Of course, you don’t get any reasonable error message when this happens. It will give you an error 1502 as shown below:
An error occurred while building the following file:
O:\Software\MfgTest\Galvo Test Station (GTS)\GTSExecutionMenu.vi
The VI became broken during the build process. Open the Build Specification and enable debugging to include the front panel and block diagrams.
Visit the Request Support page at ni.com/ask to learn more about resolving this problem. Use the following information as a reference:

Possible reason(s):
LabVIEW: Cannot save a bad VI without its block diagram.
“GTSExecutionMenu.vi” was my highest level vi that included any lvclass wires. Maybe that’s why it returned its name. Anyway what is really happening is some screw up where it breaks any vi containing any lvclass. If you enable debugging the application will work, but then if you connect to it from the development environment it will suddenly break and you can trace down and see the broken class vi’s. To fix this, the “Remove unreferenced project library members” option worked for me to keep the LVOOP intact. Of course it blows up your exe a lot bigger because you are now including every variation of every polymorphic vi instead of just the ones you are using. You shouldn’t have to do this. There is a bug in the “Remove as much as possible” option which removes LVOOP definitions that aren’t possible to remove without breaking things. I hope this helps for the next guy that tries to use LVOOP.

Yep, the appserver got hold of a usable connection but the connection was closed before the appserver had finished/committed with it. It could be that the connection was closed by the database or some firewall timeout setting.
A good start is to investigate options of configuring your appserver's connection eviction policies including forcing a validation SQL to be executed when a connection is acquired. Make sure that such a query doesn't impact on performance and have some performance and integration testing before rolling out.i found that if i close the computer which causes this issue, hence other dev computers can deploy normally.
"deploy" here i mean deploy to a running instance on each dev's machine.
From this, i would guess the common database server itself rejects connection from clients.
I will try to investigate more if i am missing something.
And here i found a link that possibly a first good attempt:
[http://www.eclipse.org/forums/index.php/m/505809/]
EclipseLink automatically recovers from communication failures, but there is little we can do to diagnose the failure. We basically execute a query and have to wait for the JDBC driver, or DataSource's response, if it hangs for 10minutes, then we are waiting. You could set the JDBC timeout hint on your query, but whether the JDBC driver honors this is up to the driver. You should see the SQLException in your logs, provided your log level is warning or lower.
If you cannot fix your firewall, they you could change your connection pool settings to use a min number of connections of 0, so there will never be idle connections. But then you will be reconnecting a lot.
You could also use a third party connection pool or DataSource that supports a timeout setting on the pooled connections, or spawn a thread in your application the clears the connection pool every 30minutes.regards,

OpenJPA - ArgumentException: Could not locate metadata for the class usi...

I'm getting the following exception when executing logic/queries around JPA entity classes:
{color:#333399}nested exception is: <1.0.0 fatal user error> org.apache.openjpa.persistence.ArgumentException: Could not locate metadata for the class using alias "MyClass". This could mean that the OpenJPA enhancer or load-time weaver was not run on the type whose alias is "MyClass". Registered alias mappings: "{MyClass=null}"{color}
I get this exception on occassion. It is intermitent and i can't seem to reproduce it consistently.
I'm using the following:
WebLogic: 10
KODO: 4.1.3.1 bundled with WL10 which in turn uses OpenJPA 1.0.0
In other forums on the net they have suggested explicitly adding the classes to the persistence.xml file ( i've done this )
They have also stated to run the openjpa enhancer on the code before deployment to WL ( done this too!)
One last step that i have yet to attempt is to load the class within the code before use ( haven't tried this as it seems so hackish)
Any other thoughts? ANyone else experience this?
Thanks

We are having the same issue.. Anybody knows how to deal with this problem?

Class hierarchy in BW

Hi,
has anyone used R/3 class hierarchy in BW reports? I would like to use classification system in R/3 to build up class hierarchies both for material and customers and use those in BW reports. At this point of time I would only be using classes without any characteristics.
Any help highly appreciated.
BR. Antti

Hi rakesh,
i am also working on the retail, also working on the same hierarchy 0material the data source is 0material-lkls_hier, the calss type is 026,
but its not updating into the infoobject currectly
in the monitoring i am gettinh like this
Transfer rules ( 911 Records ) : No errors
Hierarchies for master data received. Processing being started.
Transfer 911 data records in communication structure
Update ( 0 new / 0 changed ) : No errors
Data saved successfully
Data successfully transferred to the update
-> Start update of master data hierarchy
<- End update of master data hierarchy
Hierarchy successfully activated
but in the bex its displaying like not assigned material
how u did this... plzzz guide me

Yup. The source files are simply missing from the 4.5 source releases....I'm hitting the same issue when trying to rebuild the SDK with flexcover changes applied.

Traversing and printing class hierarchy

I'm writing a class exercise that requires taking a class as input and prints our class hierarchy for that class, includeing all the interfaces implemented by it or its superclasses. It should also print out the interfaces that those interfaces extend.
My thinking here (it's been almost a year since my last Java courses) is calling getInterfaces and getClass, and then using recursion to continually call these and print them out until gatClass returns Object.
Anybody got some input for me? Am I on the right track?

I strongly recamend you to read about java.lang.Class in the documentation and you'll find all that you need to do this.

Create a class hierarchy

How do i create a Java class hierarchy for my program. What are common classes that programs use that would be included in the hierarchy? Help would really be appreciated.

^^ that pretty much sums up how to do it
but inheritance is basically the guts of java, super duper important concept to understand. So i suggest sitting down with a good java book for a couple hours, and completely grasp the ideas of inheretance, polymorphism, encapsulation .. all that good stuff.
personally i like The Complete Reference books. i studied with them and they really do help alot

Introspection in Class hierarchy

Is it possible to have something like this in TOOL/Forte ? I am trying to introspect an Object vertically on its class hierarchy and horizontally on its data members.
public static String toDesc(Object obj, Class cls)
Class super_cls = cls.getSuperclass();
if(super_cls != null)
spr += toDesc(obj, cls.getSuperclass());
Field[] fld = cls.getDeclaredFields();
for(int i=0; i < fld.length; i++)
try
spr += "\n<" + fld.getName() + ">" + fld[i].get(obj) + "</" + fld[i].getName() + ">";
catch(Exception e)
e.printStackTrace();
return spr;

What version of UDS are you using? There are some capabilities for querying classes and set/get values. Check the UDS Programming Guidelines.
The UDS help states the following that might be helpful for you:
"...Before you can use the AttributeDesc Get and Set methods for primitive types, you must determine whether or not the type is primitive. The following code fragment accepts an object and determines if the attribute type is or is not primitive. The example also deals with subclasses of DataValue because those classes have some generic methods. The example does not actually retrieve any specific values, but the comments suggest what could be done.
method Browser.InspectAttribute(
obj : Object, attName : String)
begin
cls : ClassType = obj.GetClassType();
att : AttributeDesc = cls.GetAttribute(attName);
typ : ClassType = att.GetType();
if (typ.IsPrimitive()) then
// This type is primitive. It can be retrieved
// (and set) by using one of the Get/Set methods.
pd : PrimitiveDesc = PrimitiveDesc(typ);
elseif (typ.IsArray()) then
// This type is an array type. Determine the element
// type (if it is set) to make it possible
// to further inspect the array's elements.
ad : ArrayDesc = ArrayDesc(typ);
eType : ClassType = ad.GetElementType(); // Can be NIL
elseif (typ.IsInterface()) then
// This type is an interface type. The inspector might
// further interrogate the real object implementing
// the interface, like any other object, or
// do something special when inspecting interfaces.
else
// This type is an object type. If the type
// is a subclass of DataValue you might want to deal
// with it separately. Otherwise, if it's a simple object
dvType : ClassType = DataValue;
if (dvType.IsSuperOf(typ)) then
// The type is a subclass of DataValue.
// Once the attribute value is retrieved,
// its value can be gotten by using the
// DataValue.TextValue attribute.
else
// This is a simple object that, if not
// NIL, requires further reflection.
end if;
end if ;
end method; ..."
The key I guess is here"
"...Getting and setting the value of an attribute that is not a primitive type requires that the application know more about the current object than is necessary if its type is primitive. For example, an attribute of type Boolean might be assumed to have a default value of FALSE. But an attribute of type Array of IntegerData might have as its default value a NIL value or an empty array, or an array with a single IntegerData element initialized to 0.
To get or set the value of the current attribute when the data type is a class or interface, use the GetValue and SetValue methods. If the data type is a class, specify an object whose class is a subtype of the class. If the data type is an interface, specify an object whose class implements the interface. ..."
Remember that UDS reflection has been modeled following the Java Reflection Framework but it is not a full implementation of it.
Let me know if I can be of any further help
