A reflection error occurred accessing the object.-- Error

I am trying to update from default field value to some other value by using the script definition, however system is throwing the "A reflection error occurred accessing the object."
If anyone has any idea/solution please help me.
regards
Sumanta

Hi Devesh,
I wrote a Field Validation Script and as per your guidelines i update the script,however got the different error.
new changed script
doc.getExtensionField("CURRENCY").get().setDisplayName("AOA");
and also tried with
doc.getExtensionField("CURRENCY").get().setDisplayName("-2147483442:601:AOA");
and the error message received is like
Error executing script: Sourced file: inline evaluation of: ``doc.getExtensionField("CURRENCY").get().setDisplayName("AOA"); . . . '' : target exception.
It is not allowing to modify/update the existing field value by using script.
Please let me know if you have any suggestion.

Sumanta

-18001: An error occured accessing the LabVIEW ActiveX automation server

Hi,
I'm currently investigating a problem with a Teststand 2.0 sequence. The
sequence makes use of VI's that call methods of an ActiveX. After a few
successful loops through the test sequence the error "-18001: An error
occured accessing the LabVIEW (6.1) ActiveX automation server" is brought up
in Teststand. I think that somehow the ActiveX automation server is dying
during the execution of the sequence but I don't know where to start
searching...The problem does not seem to lie within the ActiveX istself, but
I'm not sure. Using the same ActiveX within a Visual Basic Application and
performing the same commands several times does not produce a failure. Has
anybody an idea what could be the problem
Thanks, Sven.

Thanks, but I already know these entries from the Knowledge Base. I found no
help in there and my error text is also not mentioned there.

A database error occured. The database error text is: ORA-00932: inconsiste

Hi Experts,
In WebI XI 3.1, i am getting this error when i run webi report against a derived table "A database error occured. The database error text is: ORA-00932: inconsistent datatypes: expected NUMBER got DATE ". The derived table is designed in such a way that it populates only last week data, however, the result populates data for last week and current week. For the current week, it shows date range from feb19 to feb25, so the data is not correct. how can i get rid of current week.

Hello, the error means that it is pulling a field with DATE type instead of a number, you should convert the date to a number at universe or document level.

Hi Ggraindo,
This error occured during deployment? Which is the LabVIEW adapter version that you are trying to use, is it the 9.0.1? Do you have other LabVIEW or TestStand versions installed in your computer? This error only occured when you try to used the class IviFgen, or even just with a simple VI?
What is the result of the error cluster from LabVIEW?
Also, can you post a simple exemple to reproduce this issue?

-18001; And error occurred accessing the LabVIEW ActiveX automation server.

I installed a revised TS deployment, and got this error.
For other deployments, when this error occurred, there was a simple solution - change the Adapter in TestStand.
This time, if I change the Adapter, I cannot reload the test vi's in the test sequence, so that doesn't work.
Any help would be appreciated.

Error -18004; An error occurred accessing the LabVIEW Run-Time Engine DLL. TS 4.2.1 / LV 2010

When I try to run a VI that is reentrant in parallel execution, I receive this error. The details of the error is: LabVIEW: The property or method is not supported in this version of LabVIEW.
This is run under the Simple Operator Interface in LV 2010. The TestStand engine is version 4.2.1 using LV 2010 run-time engine adapter.
If I save for previous version to LV 2009 SP1 and set the TS adapter to 9.0.1 (2009 SP1), this works.
Can anyone reproduce this error (bug?) ?
Solved!
Go to Solution.

have you got the latest updates for TestStand using LabVIEW 2010?

Anyone have any ideas? This has me stalled.

An internal database error occurred in the Business Data Connectivity Shared Service. SQL Error Number : 229

Recently i upgraded my SharePoint server 2013 to SP1, after the upgrade i received following message in manage database Status page " Databases running in compatibility range, upgrade recommended"
for Business Data Connectivity Database. Then i ran Sharepoint Configuration wizard, which fixed that error on that page but i am getting a error message while accessing BDCApplication page in manage service applications pagein central admin"
An internal database error occurred in the Business Data Connectivity Shared Service. SQL Error Number : 229
Sys Log :
The BDC Service application failed due to a SQL Exception: SQLServer host WSQLD05\DV. The error returned was: 'The EXECUTE permission was denied on the object 'proc_ar_GetAdministrationMetadataCatalogByPartitionId', database 'sp_BusinessDataConnectivity_DV13',
schema 'dbo'.'
I checked the Db role of the service app pool account, it has SPDataAccess permission over the Database. i cant recreate another application without knowing the root cause. I hope i can get better option to troubleshoot the issue.
Thank you

As per the error message, you can at least grant the BDC service application pool account the EXECUTE perimssions on the sp_BusinessDataConnectivity_DV13 database

Hi,
a big problem with our report server has appeared suddenly.

The last think I have done, is to grant a new user access to the report server website (by using the site options) and to the root folder (by using the folder options on ws).
But the error must not relate to the new user. The server was not touched for several days before.
Could you plz help me? I have no idea what to do.

Error occurred saving the cache

I'm creating an AIR application using the Model Driven Development tools and hoping to make use of the offline cache. The generated value objects and services are working well when connected but I have been unable to get the cache working.
Currently I am generating custom offline adaptors for each of my Model entities and assigning them to the offlineAdapter property of each data service as follows:
_terminalService.serviceControl.autoCommit=false;
_terminalService.serviceControl.autoConnect=true;
_terminalService.serviceControl.fallBackToLocalFill=true;
_terminalService.serviceControl.autoSaveCache=true;
_terminalService.serviceControl.autoMerge=true;
_terminalService.serviceControl.autoSyncEnabled=true;
_terminalService.serviceControl.encryptLocalCache=false;
_terminalService.serviceControl.offlineAdapter=new TerminalOfflineAdapter();
_terminalService.serviceControl.cacheID="ss-sclient-39";
When I run my application it works as anticipated but I am seeing the following error in the console log:

I'm slightly confused by the fact that the offline adaptors are derived from SQLiteOfflineAdapter and are being run within an AIR application but I am still seeing references to the LSODataStore in the logs (which I thought was only used for Flash applications). Also if I attempt to set encryptLocalCache to true I get the following error:
7/27/2010 12:32:10.409 [DEBUG] mx.data.DataStore Adding data service: common.Terminal to the data store: my-rtmp:true initialized: false
Error: Encryption is not supported for local shared objects.

Does anyone know what's going on here?
Thanks!

Ah, thanks! That certainly solves the LSO issue - I've changed to linking with airfds.swc and I'm now seeing lots of healthy looking SQLDBCache output in the logs when I run the application with a connection. Unfortunately if I then stop the server and run the application again I'm still seeing a problem. The app does load some data from the cache (I have several services) but then stops with the following error before it can load everything:
7/27/2010 15:43:46.929 [DEBUG] mx.data.SQLDBCache SQLDBCache - getCollection(_common.Customer_ic) creating new collection

In both connected and disconnected operation there is no user input, so the sequence of queries should be identical. Each service I use is configured identically except that they each use their own automatically-generated OfflineAdaptor. Any suggestions?
Many thanks
