Hi Regina,

As per my earlier responses in those questions you need to have a client script section to handle this i.e. setting the filter attribute dynamically.

Did you try using the client script section as well to set the filter attribute as per my comments on those questions. Using that you should be able to achieve that.

It's simple. onChange of first lookup I am calling method present in client script section and setting the filter attribute for second <g:ui_reference> tag.

Mark Correct if this solves your issue and also hit Like and Helpful if you find my response worthy based on the impact.

Thanks
