vRealize 7 - custom property variables still possible?

Hi Folks,

in vRA 6+ it was possible to pass variables in custom properties.

Now I tried the same in vRA 7.

Example:

custom property in the BusinessGroup:

 

I'mACustomPropertyVariable1 = 123

I'mACustomPropertyVariable2 = 456

 

custom property in the Blueprint:

 

IWantToGetVariable1And2 = {I'mACustomPropertyVariable1},{I'mACustomPropertyVariable2}

 

Result:
IWantToGetVariable1And2 = 123,456

That doesn't work anymore.

Any Ideas?

Thank you in advance

Susie
