Error 1054 Open VI Object Reference

Hi Ppl,
I'm using LabVIEW 8.6 and I'm debugging a code that uses the Open VI Object Reference node. The parent reference thats passed in is a refrence of a VI instance and the vi object class is the control type. Though the control is present in the VI, the node returns error 1054 and says object not found.
I'm wondering why this was. However when the parent is the VI reference itself instead of the instance VI this works. I'm not able to understand the problem.
Thanks,
Sathish

Sorry, I made what you have told me:
now i have this error:
why? If you have implemented a correct Vi can you give me it please?
Thanks!

Version 4 Error: Expected Container, found Object Reference

We're in the process of upgrading our sequences from 3.5 to
4.0 and for the most part, everything is seamless. However, there is one situation I’ve found
that throws a RTE in 4.0 but works fine in 3.5.
When calling SetPropertyObject on an object reference, the following
error is thrown:
Parameter 'newValue': Expected Container, found Object Reference.
-17308; Specified value does not have the expected type.
Attached is a sequence snippet illustrating this
behavior. The last step should assign
the variable in Parameters with the name in TempStr (“Fred” in this example) to
the first element in the TraceObjRefs array (an array of object references).
What is really confounding is that this works as expected in
3.5. Any insight as to what changed or
what’s the best way to work around this?

AliasBreak35.seq ‏46 KB

We are seeing something similar in TS 4.1.
We have a container with subproperties which are also containers (of the same type actually). Technically, this is an array, we are using the container to be able to address by name. When I extract one of the sub-properties either by GetPropertyObject or by GetNthSubproperty and then try to assign it to a container of the same type, I get the error "Expected container, found object reference".
I attached a sequence with some experiments, using the NI_Limits type and found a solution: the Evaluate method seems to actually copy the values from the source container to the target; but only when it is not called as "PropertyObject.Evaluate()" but stand alone.
But I did not quite understand the mechanics of the aliases. In the sequence, I create an alias, as indicated in the previous posts. Then I can apparently not change that alias again. I used the "Data" member in the NI_Limits container to differentiate between the individual containers.
After the second SetPropertyObject, the value stays the same as before. But when I then change the value in one of the source objects, the other changes with it.
So I am not quite clear what an alias actually is and what its effects are.

Peter

Error(Access via 'NULL' object reference ) in link to action

Hi,
 I have a table-VBAK with "LinkToAction" is one of my column,Once i click that action,i want to call one more table-VBAP in the "TablePopin".
OnAction of "LinkToAction"
I called the another Table(VBAP)-"TablePopin" with the help of following code,
context_element->set_attribute( name = 'SELECTED_POPIN' value = 'TABLEPOPIN' ).
Now i want to fill the VBAP-Table.
So OnAction of "LinkToAction".
i called the
method ONACTIONOPEN_POPIN .
DATA:
 NODE_VBAK1 TYPE REF TO IF_WD_CONTEXT_NODE,
 ELEM_VBAK1 TYPE REF TO IF_WD_CONTEXT_ELEMENT,
 STRU_VBAK1 TYPE WD_THIS->ELEMENT_VBAK1,
 wa_vbap type vbap,
 itab_vbap like table of wa_vbap.
navigate from <CONTEXT> to <VBAK1> via lead selection
NODE_VBAK1 = WD_CONTEXT->GET_CHILD_NODE( NAME = 'VBAK1' ).
@TODO handle not set lead selection
IF ( NODE_VBAK1 IS INITIAL ).
ENDIF.
get element via lead selection
ELEM_VBAK1 = NODE_VBAK1->GET_ELEMENT( ).
@TODO handle not set lead selection
IF ( ELEM_VBAK1 IS INITIAL ).
ENDIF.
ELEM_VBAK1->GET_STATIC_ATTRIBUTES(
 IMPORTING
 STATIC_ATTRIBUTES = STRU_VBAK1 ).
if stru_vbak1 is not initial.
select * from vbap into table itab_vbap where vbeln = STRU_VBAK1-vbeln.
endif.
context_element->set_attribute( name = 'SELECTED_POPIN' value = 'TABLEPOPIN' ).
endmethod.
i set the break point and check it.once it enter into the following area of the above code,i am getting error like Access via 'NULL' object reference
ELEM_VBAK1->GET_STATIC_ATTRIBUTES(
 IMPORTING
 STATIC_ATTRIBUTES = STRU_VBAK1 ).
Now my problem is,i want to fill the VBAP-Table in my "TablePopin".Once i click the "LinktoAction" in my Main Table.
can any body share your ideas.
Thanks in Advance,
Regards,
Ravi.

Hi Ravi,
Have you filled in the node_vbak1 with some elements? Lets say in a supply function or wddoinit etc.?
Just check that. After that, make sure you have IntializeLeadSelection property set to true for the node_vbak1.
Hope this helps.

Error when opening view object in Jdeveloper

Hi,
EBS version is 11.5.10 RUP4. JDeveloper version is 9.0.3, Business Component Version is 9.0.3.13.93.
We need to modify a custom view object that has been extended from a standard VO. We do not have the original Java file of the custom VO, only its classes VOImpl and VORowImpl. As such, this should not be a problem: instead of modifying the custom VO we could extend it.
The problem:
When trying to update/extend the custom VO we get an error:
Copy operation failed, some edits may not be cancellable
Expected name instead of <.
Exception in oracle.xml.parser.v2.XMLParseException
Tracing back the problem we got this same error when OPENING the original VO. The original VO is oracle.apps.asn.opportunity.server.OpptySearchVO
Any idea how we can solve this problem?
Thanks in advance.
Regards,
Radu

Radu,
What kind of change you are trying to do, If you are try to change only the query without adding any parameter, you can open the VO.xml in a text file and change it.
One more way is, create a new VO substitution with the same name, and extend the VO, then Copy the VOImpl and VORowImpl code into your new files and use it.
What is the Jdeveloper Version 9.0.3 or 9.0.3.5
What is the Build version for the Jdeveloper.
Thanks.
With Regards,
Kali.

Rapidwiz error cannot open shared object file: libpthread.so.0 libc.so.6

Hi,
We are following Note 238276.1 Migrating to Linux with Oracle Applications Release 11i, trying to install the technology stack (Section 2: Step 4), in a RHEL5 64Bits.
We have downloaded the startCD (B29029-01) and the TechStack CDs (B29032-01_2of2). When running the ./rapidwiz from startCD, we get following error:

Yes, thats correct ...
The actual situation is:
-Customer has split configuration: DB 11g in RHEL5x86-64Bits + APPS 11.5.10.2 in Windows2003
-The target is to have all DB11g and APPS R12 in single node RHEL5x86-64Bits
We're following Note "Migrating to Linux with Oracle Applications Release 11i [ID 238276.1]" to migrate the APPS server from Windows to Linux, as a middle/temporary step prior to make the Migration to R12.
We are trying to do it, but we get errors during Section 2.4 "Install the Middle Tier Technology Stack", running the rapidwiz command we get errors, because of R11i is not supported in 64bits platforms (Oracle Applications Installation Update Notes, Release 11i (11.5.10.2) [ID 316806.1])
Our bigest doubt now is that we are trying to install 11i techstack into RHEL5 x86-64bits, and we think this is not possible, because of R11i is not supported in 64bits platforms !!!
That is, could we migrate the APPS server from Windows to Linux x86-64 as a temporary step to begin the upgrate to R12 all in RHEL5x86-84bits, that is full supported on this 64bit platform?
What possibilities do we have if we can't do this?
Theese can be some of them:
1-Migrate apps server from actual windows2003 to Linux 32bit, in other host with 32 bits installed, instead of 64bits, and move here from windows to lilnux 32bits, and the begin the R12migration
2-Migrate to R12 into actual appserver Windows2003 and then migrate appserver from windows to rhel5-64bits
I don't like second option, because we want to make the R12 upgrade into Linux, not in windows. We need to eliminate windows platform as soon as we can.
Thanks in advance ,

Error while opening BC4J objects in Jdev 10G

I downloaded the jdev 10.1.3.3 version , copied the entire JAVA_TOP files to myclasses on my local machine. In the project content property i gave the path to myprojects.
In the include section i included only oracle\apps\ego since these are the only files i need to modify.
Now when I right click on one of the EOs in jdev, i get an error message that there are java errors in the underlying EOImpl.java and the wizard will open read only.
I did not modify any files. These are all oracle shipped files. This happens with a few other objects. I am able to open some of the BC4J objects but some of them give me this error mesage.
When I build the project , i do not see any errors, I am even able to run a page.
What is wrong here. is it some missing library or do i need to include additional files/folders .. Please help
thanks,

I deleted the class files from myprojects and tried opening the EO but that din't help. I created a new project after deleting all the class files, even now i get the same error.
I wonder if reinstalling jdev will solve the issue? I have only xml files in the myprojects folder but i keep getting the same message that there exist errors in the .java file under the myprojects folder.
I'm not sure what's going on. Is there some cache that jdev is looking at.

BSP - 500 Internal Server Error Access via 'NULL' object reference not possible.

Hello Colleagues, I'm new to BSP maybe someone could help me.
I’m taking data from a DB table through select an put them into htmlb tables.

Getting error on Portal : Access via 'NULL' object reference not possible

hi friends,
While executing a bapi,I am getting this error : Access via 'NULL' object reference not possible., error key: RFC_ERROR_SYSTEM_FAILURE
I am calling a bapi with only one required parameter from Portal as per the design of the bapi and the bapi itself is calling some other functions internally.
I a using ECC 5.00 i,e. EA-HR 5.00. On SDN it is suggested to Apply OSS Note 1018036. But it is applicable to EA-HR 6.00 and subsequent releases,I guess.
Need your suggestions and also need to know if the above Note can be applied to EA-HR 5.00.
P.S: Points would be assigned, thanks is advance.

Close reference needed for step object reference open? If so, how?

Hello,
We are using an activex method call to open an object reference to a step and programatically rename it. This is done many many times during our test run, thousands. We ran into an "out of memory" problem we had never seen before during a 72 hour test run, and in hunting down any possible memory leaks, I am wondering if a corresponding close is needed for the step reference open we are doing, and how. I have hunted around the different methods/properties, and can't seem to find if there is a step reference close. I have attached the specify module screen of the activex call which opens the step reference.
Thanks for any replies

Hi David,
Setting a reference to nothing in TestStand will close it. However, if you are assigning a new value to the local it also frees the memory associated with the original value, making it so you don't need to assign it to nothing. I don't believe the source of the leak is in this step.

Field-symbols v/s Object references in OO-ABAP

Hi,
can anyone please tell me what is the difference between using field-symbols and object references in OO ABAP? Is there a specific need for field-symbols now that we have references?
Thanks.
Shakul.

Hi ,
Please note that both Field symbols & Object References are different .
You can use Field symbols during the following situations
1) When you want to modify the value of internal table, the field symbol would be useful since you do not have to use any Modify statement as in case of work area. The Field symbol works as a pointer and any changes to the field symbol will directly affect the value of the internal table
2) Make sure that you do not reassign the field symbol within a Loop iteration
3) Field symbols are useful when you work with dynamic internal tables ( tables whose structure is determined during run time)
4) After Read an internal table ( Read itab...) into a Field symbol, make sure you do a Sy-subrc check or check if the field symbol is assigned.IF not this will give you a run time error
You can use Object References while creating an object to a class. They are instances of a class.
Thanks,

RFC to HTTP Interface - Access using NULL object reference is not possible

Hi All,
I am working on a Interface RFC to HTTP where in I am sending the data to a third party system.
Using PI 7.3 and Adapter type XI to send this data.
I am getitng an error Short dump occured when executing message in qRFC queue <Queuename>: Date/time 02.12.2011 08:44:57, user XXXXX, runtime error: Access using NULL object reference is not possible.
<SAP:Code area="INTERNAL">QRFC_SYSTEM_DUMP</SAP:Code>
I am entering the parameters such as target host,service number,path correctly with addrseing type as URL.
The message is failing in the call adapter step with the above error.
There are no messages stuck in SMQ2 as well.
Now on the other if I use the adapter type HTTP_AAE the messages is getting successfully delivered with the same parameters mentioned above.But as we know it is a plain adapter and will not have the SOAP envelope.
We would want to send the data using the XI adapter.
Any idea as why this issue is happening?
Helpful answers will be rewarded points.
