1059 LabVIEW attempted to load the class at this path: <Empty Path>

[bdwhaley]

I've seen a few 1059 errors already posted, but not one like this. Can some one help?

I've created a simple vi that graphs a random number.  (See attached).

Here is the dialog window message:

Error 1059 occurred at Get LV Class Default Value.vi

Possible reason(s):

LabVIEW:  Unexpected file type.

Complete call chain:

     Get LV Class Default Value.vi

     AB_UI_Initialize_Framework.vi

     AB_UI_FRAMEWORK.vi

     AB_Item_OnDoProperties.vi

     AB_Item_OnDoProperties.vi.ProxyCaller

LabVIEW attempted to load the class at this path:

<Empty Path>

Hello bdwhaley,

From what I've found so far this error typically occurs in either sourced distributions or in a built application. The VI that you attached to illustrate this issue had no problems on my PC and it ran as expected.

When this error occurs in the application builder it is usually resolved by simply rebuilding the build specifications and the build, there is also typically a blue circle with a question mark on the build specifications. Are  you using the application builder in any way?

Could you provide any additional information such as OS, LabVIEW version, or if any other basic VI's are exhibiting this behavior?

Cheers,

Joel
