I have 2 custom fields that I need to change from a string to HTML. However every time I attempt this I get the following error "Element is using storage alias. Cannot modify this element's type because it shares a storage alias:[task.u_test shared with 2 total element(s)]. I was able to change a couple of them that where not custom fields. I know there is a work around, but I do not/cannot delete it and rebuild it as it contains information that is still needed for past changes.
Thank You in advanced

Hi Troy
This is due to a feature in the platform known as task flattening. This was put in place in Dublin as a performance enhancement at runtime. Several string fields on various tables are using the same physical database field to store information. As a result, you cannot change your field type because it would impact the other fields.
Your best bet is to create a new field of type HTML and migrate your information from the string field to the HTML field (if you wish to preserve the content.)

Cheers, thanks Chuck! I regret not being able to get to Knowledge this year, but I hope it's a great success on your end. Maybe next year I'll head out finally

Hello Chuck
I have faced the same issue and found that error message on top of the form when trying to change the field type. To get rid of this, I'm creating a custom field(Type: Reference) in a scoped application (GRC profiles). When I configure-->form layout and try to a add a new field to the 'Selected' slush bucket with type reference and reference qualifier on group table, once I save the form I see the field turns around to single line text field.
Any thoughts on this will be appreciated.
Regards!
