Global variable of type "List" is this possible in BPEL?

Map filterMap = new HashMap();
filterMap.put(WorklistService.FILTER_TYPE_TASK_FILTER,
WorklistService.TASK_FILTER_DEFAULT);
filterMap.put(WorklistService.FILTER_TYPE_STATUS_FILTER,
WorklistService.STATUS_FILTER_ASSIGNED);
WorklistService wlSvc = WorklistService.getWorklistService();
IWorklistContext ctx = wlSvc.authenticateUser("jcooper", "");
List tasks = wlSvc.getWorklistTasks(ctx,
filterMap,
WorklistService.SORT_FIELD_TASK_TITLE,
WorklistService.SORT_ORDER_ASCENDING);
My question is, is it possible to have the variable tasks which is of type "List" to be accessable in another Java Embedding?

What do you pass to the config variable?

More details about Surprising LV global variable of type 2

I'm using a type 2 global variable because I need a big data array shared by
two parallel VI, so this data array is manipulated in a subVI non reentrant.
One input of this subVI is an enum called method which represents what
action to do on the data of the subVI and this input is directly wired to a
condition structure.
The big data array is contained by an indicator in the front panel of this
subVI because
this big data is an output of the load method so this indicator is wired as
output connector of the subVI because it is needed when loaded.
For other method the big data array is read to extract part of needed data,
so in the subVI diagramm, a readable local variable issued from the big data
arra
y terminal is used . But how big data array is not needed for these
methods, big data array terminal is not rewritten as output in these
condition diagramms because the big data array is theoretically unchanged
and I want to avoid to duplicate my big data array to save time and memory.
The result is surprising because:
After the load method, the big data array output is right.
Then, the input of the second subVI call as a get method is correct.
Readable local variable of the big data array sends right data as input of
the condition associated with this method, in the subVI.
Then, the input of the third subVI call as a get method is wrong. Readable
local variable of the big data array sends wrong data as input of the
condition associated with this method, in the subVI.
So, I suppose I have to wire my big array as output of the condition for
every method call, what lose
a lot of time and memory.
Have you a better idea, please?

Brice,
Are you using a while loop with uninitialized shift-registers in your LV2
style global. This technique is what defines a "LV2 style global" also
called functional globals because you can embed actual functionality into
the VI (for example in your case to extract certain data from an array and
operate on it) as opposed to the read/write only usage of the built in
globals.
From what I can gather, it doesn't sound like you are using the while
loop/shift-register method. You shouldn't need to use a local variable at
all. The data is passed around using the shift-register and it passes
through all of you conditions (load, get, etc.) and no you won't lose time
and memory (or money) doing it this way, certainly not any more than you
would using a local variable. Try it and see if it doesn't fix your
problems and work better than what you are doing now.
If you are using a while loop and shift-registers, then I'm not
understanding clearly what you are doing. Perhaps if you emailed me your VI
(privately of course) to take a look at.
Good Luck!

Surprising LV global variable of type 2

I'm using a type 2 global variable because I need a big data array shared by
two parallel VI.
The big data array is contained by an indicator in the front panel because
this big data is an output of the load method.
This big data array is an input of other methods so as in the LV example, a
local variable of the big data array is used as input and I have not wired
the big data array indicator as ouput for these methods in order to avoid to
duplicate my big data array.
The result is surprising because:
After the load method, the outputs are right.
The inputs of an other method is correct (local variable) but the data array
changed although I don't changed it .
So the inputs of the second other method are wrong.
So, I
suppose I have to rewrite my big array at every method call, what lose
a lot of time and memory.
Have you a better idea, please?

Its not exactly clear why you are doing this. A global can't be written
to by
a local, and neither of your options have mentioned a wire going from function
one to function two. I'd suggest that you may not need to use a global
at all,
just a wire.
If you are using a LV2 style global, then you make a call to a subVI
that returns
the needed data on a wire and passes it to the rest of the diagram. This method
doesn't save anything if you are always accessing the entire array.

Knowing the Object type? Is this possible?

Can we know the type of the object created ? Is there any method
that lets you know the type of object?
For example:
class Superclass{
class Subclass extends Superclass{
class TestInheritance{
public static void main(String[] args){
Subclass subClass = new Subclass();
}Now,Subclass is of type Subclass and also of type Superclass.
Right?
IS there any way or method I can find out the type of Subclass? ie
Subclass is of type 'Subclass' and 'Superclass'.

These might help:
instanceof operator.
also
Object.getClass().className()

Advantage of global variable usage

Hi,
I have a forms 6i form that calls another form. I need to pass parameters from the calling form to the called form. There are two options : GLOBAL VARIABLES or PARAMETER LIST. Please advise which is the best option? This is very urgent and i would appreciate all prompt replies.

Francois Degrelle wrote:
Hello,
You would find the answer in the documentation.
GLOBAL is read/write and always Varchar and limited to 256 characters.
Parameter is read only in the called form, but can by type of Varchar, number or date
Global is more interesting when you have to share a value between 2 forms, and get the updated value in the calling form.

Global variable in a Table

Hi!
Can i use any column in a table as a global variable? Is it at all possible in Any version of Oracle? I know that if we use package - we can create a global a variable there. If u had any knowledge pls reply.
Satyaki.

Hi Satyaki,
Try to understand the difference between a variable and coumn of the table.
What exactly you need a global variable for the application or own Datatype for a table?
If you requirement is variable then use Package without body or type object. But if your requirement is your own datatype use TYPE in the table.
Thanx.. Ratan

Selection screen values in global variable user exit

Hi all,
I made a project report global variable of type 3 (User Exit) and I develop the related code in enhancement KKDR0001 component EXIT_SAPLKYP1_003. In this code I need the value of project definition that user entered on selection screen.
Does anybody know how can I get this data?
Thanks!

Hi,
You can do the following for getting project in Earlier screen
Data: l_string(20) type c
Field-symbols: <fs> type any.
l_string = '(Screen)variable name'.
assign l_string to <FS>.
Just try above...

Incorrect value for global variable

Hi,
I am facing an issue in a query. In the query there is a Global variable 'Volume type'. In the default value tab of the variable it is given Default value as Litre. In the table RSZGLOBV also i have checked the global variable and there also the 'Internal Characterestic value' is shown as Litre itself. But when I execute the query, it is giving an out put like:
For the keyfigure Volume,
If the keyfigure is having some non zero value, it is showing Litre.
If the kayfigure value is zero, it is showing KG.(which is wrong). For zero also it should display 0.00KG.
Please help.

Hi Nitin,
changing the default within the variable would impact all queries.
Only if it was an exit variable, you could define within the exit to do different things depending on the query.
I would suggest the user uses personalization - but this impacts all queries where this variable is used for this user.

SEM-BPS: Variables of type hierarchy node user exit

Hi,
I read the "How to.." document "Variables of Type Exit".
This document has example for variable type caracteristic.
I need to use this kind of solution for global variables:
I have the same variables in several planning areas. I have defined one leading area containing the variable that should automatically set/adjust the corresponding variables in the other planning areas.
I've created a SEM variable of type hierarchy node and with the replacement type user exit. There is a standard function module API_SEMBPS_VARIABLE_GETDETAIL which has to provide the selected hierarchy node in leading area to other areas.
The function works ideally in test mode, but it doesn't work as the SEM user exit.
Does anyone have experience in this problem?
Thanks

Your function module shall follow the expected interface (required for exit type). Function API_SEMBPS_VARIABLE_GETDETAIL is not for such usage.
To see an example FM that is fit for a 'user exit' processing for hierarchy node, have a look at FM UPF_VARIABLE_USER_EXIT_HIER. There is inline documentation in the source code that shall help you create your own FM if required.
cheers,

Global variables for circular buffer

Hallo!
I have another question:
I need to have a variable circular buffer size. So I would like to define the circular buffer size by a global varable.
Is that possible? I tried to use the global variable like {VAR_01} to insert in the desired field for circular buffer size, but dasylab only puts a zero in the field.
Thank you and have a nice day.
Hilby
Solved!
Go to Solution.

Unfortunately it is not possible to have a variable-sized buffer. Right-click into the corresponding textfield: the context menu does not show an entry to choose the global variable from a list.

Global variable problem

hi all
if i use this SELECT 'C' || mycodes.NEXTVAL INTO :ins2.code FROM DUAL; on pre-insert trigger so the global variable is not working for this field :ins2.code..
but if i use on key-commit then working but i want to use on pre-insert
here is my key-commit trigger codes
begin
SELECT 'C' || mycodes.NEXTVAL INTO :ins2.code FROM DUAL;
if
:ins2.name is not null
then
:global.name := :ins2.name;
:global.code := :ins2.code;
commit_form;
end if;
end;
plz help me out thanks in advance
sarah
Edited by: SarahSarahSarah on Sep 7, 2009 6:41 AM

Hi Sarah!
The pre-insert trigger fires just when you call the commit_form build-in.
So :ins2.code and :ins2.name are still null when you try to assign the values to the globals.
Put the code inside the pre-insert trigger direct after the sequence-select.
if
:ins2.name is not null
then
:global.name := :ins2.name;
:global.code := :ins2.code;
end if;
end;and the key-commit trigger:
if
:ins2.name is not null
then
commit_form;
end if;
end;or assign the values to the globals after the call to the commit_form build-in:
if
:ins2.name is not null
then
commit_form;
:global.name := :ins2.name;
:global.code := :ins2.code;
end if;
end;Regards

GLOBAL VARIABLES FOR NON-ORACLE DATABASE

What is the alternative of global variables in Form 5.0 when using non-oracle databases. I know one way is passing parameters, is there any other way? I have few variables which need to be global in my application.
Thank you
null

There is no other way.. you have to use either Global variables or parameter lists to pass values from one form to another form.. With in the form you can always use null canvas item to store and pass values in different program units or triggers..
have a nice day

Global variable corruption

hi
im using labview 6.1.
i have a frame in a sub-vi that that reads 16 bytes from com7 (in my pc) into a global variable using a custom DLL. this variable is then used later to compare some data in another sub-vi.
this was working fine for a day, then this morning i started it again and ran it. when i got to the point where this "read" happens i got a dr watson exception message. (i am running the application on nt4 in the development environment). after this point the gloabal had rubbish in it whenever i did a read, although it did also hold the basic read data. after a reboot etc it still did it. the fix was to completely remove this global from the application vi and my file globals.vi , create a new one and then use that in the same manner.
everything was ok for an hour.
then the same thing happened again.
any ideas? this is really annoying.

It sounds like you're DLL is corrupting LabVIEW's memory. This doesn't necessarily mean you're DLL is doing anything wrong. It just means you have to be careful when calling external code in LabVIEW to make sure that it plays nice and doesn't stomp on LabVIEW's internal memory.
If you expect your DLL to output a 16-character buffer on every call, then you should be passing in a dummy string into the buffer input for your Call Library Function Node of at least 16 characters in length. This will help LabVIEW allocate the data correctly and pass it into the DLL to operate on. The DLL should not resize this buffer, because LabVIEW won't be notified.
Are you doing anything along these lines?

when i investigated WF_Metadata_files i saw there is a global called INPUT_DIR i assume I have to change the path there. I tried to find old directory in the batch job but i cant find it and even When i give value to global variable it is still pointing to old path.
Can anybody please help me.
Thanks
Tim

Hi Tim,
If having specified the value in the global variable it is still pointing to the old path there can be a couple of scenarios applicable
1. There is a different global varaiable being used for the file path
2. The filepath is hardcoded in the file-format or Excel file definition despite the declaration of the global variable.
Are you getting this error when running a dataflow within this workflow or in a script? It will be better to run the workflow in debug mode and look through the stages to find out where exactly in the workflow it fails.
kind regards
Raghu

Listing global variables

Is there a way to list all global variables in a multi-form app without actually knowing the names of the variables? We have some FMX files without source code, and I would like to create a form that would just list these globals. Possible or not? Or put another way, is there a way to grab these globals from the memory area?

The only idea that comes to my mind : start the debugger from Forms Builder with your starting module, and when reaching a breakpoint (which has to be set before) you can see in the middle of the debugger a window (the navigator pane) a navigator tree. Click on Global Variables and you can see all Globals and their values which do exist the time your program reaches the breakpoint.
Hope this may help you
Kai
