Parameters grayed out when passing mroe than 4 properties in a cluster

[Notepid]

I have created a VI that passes a number of parameters to TS through a cluster, however, it fails to run the sequence, and I am unable to edit the parameter settings since they are all disabled.

It seems that it works fine when I pass 3 or less parameters in the cluster, but as soon as I add the 4th it no longer accepts the cluster as an input.

Any ideas on why the number of cluster members seems to be limited to 3? or is there any magic settings I have failed to locate?

In advance thank you for your time and assistance!

In the old days of TestStand, there was a fixed prototype for calling LabVIEW steps.  One of the valid parameters was a TestData cluster that consisted of those four items.  In order to preserve backward compatibility when we moved to having a flexible adapter, any clusters of that type get automatically mapped to the locations described in the step.

If your cluster is different than the Test Data structure, it should allow you to edit the parameters.

Thank you for your reply!

I solved this by renaming the return cluster to something other than "Test Data", and it worked. Thank you for you help!
