Description of problem:
I was trying to blacklist some packages via package filters. And I tried package filters from cli since filters are not working from webUI. A defect is already logged (755522).

So this time, I created filters from cli and tried to promote the product from UI. when I promoted the product from 'locker' to next env. Product is promoted with applied filters.

Now I created a new changeset and tried to promote the blacklisted packages because +ADD option was available. When I clicked on +Add to add the package n changeset, got ""Validation failed: Packages is invalid". UI completely hanged. (See first attachment)

Version-Release number of selected component (if applicable):


How reproducible:
always for me

Steps to Reproduce:
1. Add a product/repo either from UI or cli
2. Define filters from cli
3. Promote the product from UI
4. No create new changeset and tried to promote the blacklisted packages.

  
Actual results:
"Validation failed: Packages is invalid"

Expected results:
I'm not quite sure. I think it shouldn't be allowed to promote blacklisted packages.
