vCAC Plug-In createModelEntity failing with java.lang.Double cannot be cast to java.lang.Short

[JackBS]

Using vCAC plug-in (5.1) I was trying to create a vCAC PhysicalMachine Entity.  Couple of of attributes in PhysicalMachine Entity are numeric type.

For example: To create a PhysicalMachineEntity I am sending below properties map to createModelEntity

var physicalMachineProps = {

        PhysicalMachineID = "UUID",

        MemoryInMB=1121,

        ProcessorCount=2,

        Vendor="Vendor",

        AssetTag="SDSDSD",

        Model="usrLbl",

        ServiceTag="DN",

        Slot=0

    };

createModelEntity always failing with java.lang.Double cannot be cast to java.lang.Short error. Looks like number type from Rhino always getting converted to java.lang.Double and its failing at plugin. How can we force type to be Short

Any one have seen this. Appreciate any inputs on this.

Caused by: java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.Short

I think this seems to be an issue with Int16 type attributes.

I am affraid you cannot force the type at the javascript level. This casting issue must be addressed within the plug-in. Please open a support request at VMware Global support services to get a new build that will correct this issue. Please mention bug 1203454 (I created it for making you save some time in the process but it will get prioritized only once you open a support request for it).

[JackBS · Accepted solution]

Thanks, Will open a support request. For now workaround is to remove Slot attribute from Properties, then I was able to create PhysicalMachine Entity. But there could be other entities with Int16

[vdimitrov]

Bug 1203454 has been fixed. You will need the new build for this to work (fixed for both 5.2 and 6.0 versions of the plug-in).

Another thing - if you're creating a new Physical Machine entity, you don't need to specify the PhysicalMachineID, it will be generated for you automatically.

Thanks Vladimir. Another bug eradicated promptly

[JackBS]

Yes, you are correct PhysicalMachineID is not required.

Thanks for a quick fix.
