Hi,
I have a vf page which has several page block tables on all with inline edit support enabled. Within the tables there are controlling(Product_Category__c) and dependent(Make__c) picklists. My issue is that the the controlling picklist has a FLS of read only as it is set via a trigger, when I put this field onto the vf page, I get the error of 'The inline edit-enabled dependent picklist 'Make' requires its controlling field 'Product Category' to be present on the page.' when a profile other than system admin views the page. If I remove the read only flags from the FLS and set it at a page layout level, the user can then view the vf page, but the controlling field becomes editable.
Does anyone have any suggestions how I can get around this?

This is my vf page.  I have several pageblocktables within the page, but I've removed all but one for ease of reading.

Many thanks for any help
