Problem with data value reference creation


Recommended Posts

Hello!

Im trying to create a data value reference to an object (of a type i created), but it seems like there is an issue with my objects that makes them incompatible with DVR.

The error I get is: "You have connected to a polymorphic terminal that cannot accept this data type."

I have seen many example of code using this technique, so there must be something I've done wrong.

See image: (hopefully you area able to see it)

Hi again!

Sorry for the (very) late response.

You are right, but the error message you refer to is shown first when you try to execute the broken vi. If you hold the wire tool over the broken wire, you will get the message in the original post (that isn't very helpfull).

I wasn't stuborn enough, and didn't try to execute the broken vi. So i didnt see the better error message. :-)

You should get used to it. Clicking the broken run arrow opens the error list window, which shows all the errors in your hierarchy and provides more details than the tool tip description. It's a tool which you should get accustomed to using (hint: the VIs which are actually broken appear at the top of the list and have red Xs next to them).
