Copy a component from single csys to multiple csys- Nx Journal

[Kumaresh_07]

Hello Cowski and Fellow Members,

I would like to copy a component from single csys to multiple csys in Nx Assembly part.

I got most of the code from cowski's replies. He wrote code for move a component from one csys to another csys's.
But my requirement is I need to copy component from one csys to n number of csys's.
so I had modified that code with "SelectTaggedObjects" method. but I missed something else. so It's shows
"System.InvalidCastException" error. I tried in all ways. But I can't able to figure out the issue.

Modified code and Error image attached below.

While run the below Journal,
Step 1)user going to select csys of component(From csys).
Step 2)user going to select destination csys's (Here user can select multiple Csys's of Nx Assembly)
Result : selected component placed in all csys's ,which I selected in step 2.
Above step 1 & 2 are worked But After journal Execution the component not placed in csys's. Journal window shows "System.InvalidCastException" error)

Error image Attached below vb code.

It would be great , if someone help with this.
