[Vtigercrm-developers] Creating a custom UIType?

[Alan Lord]

Following up a bit on this, I'd like to make my new custom field 
read-only in Detail View, i.e. disable Ajax Editing.

However the method isAjaxEditable() exists in the Vtiger_Field_Model 
(even though it mostly tests for UITypes), not in the UIType_Model which 
seems a bit odd to me and I can't see an easy way to extend/override the 
Field_Model class?

I can do it from the client-side fairly easily but this method just 
seems to be in the wrong class to me - by being in the Field_Model it's 
suggesting that the function is dependent on the current *Module*, not 
the current Field...?

Cheers

Al
