The ability to set a portlet (record, table) to be editable based on the value of a variable, be it a variable from the data component or another portlet, would be really helpful in cases where a portlet shouldn't be editable depending on the data.

For example, selecting the rows that are not highlighted in green in the top portlet should set the record portlet below to editable while selecting the green rows should set it as non-editable.
