Hi,
I wanted to check the linking issue has a correct custom field value.
i.e. I have custom field 'Feature Type' and values "Product Feature" and "Technical Feature" on the linking issue and now I want to validate this issue on the other issue which going to link and contain Product Feature or not.
Example: 
On the create screen, "GTN-28761" which is going link to another issue and I want to add validation that GTN-28761 has a value of Product Feature or not to show here (another issue create screen).
Thanks
