Increase storage size of sys_EditBox

I have a Content Type called ‘lsaQuickFacts’ and in ‘Fields and Field Sets’ there is the Control ‘sys_EditBox’ and I need to increase the storage size. I have two options in the dropdown, 50 and max. I choose max and then restart Rhythmyx and then try to add a 71 character string and get an error stating (among other things):
(actual: 71, maximum: 50)

Is 50 the max? And if so, how can I increase this?

Thanks,
Todd

The automatically created validation remains unchanged when you modify the storage size of a field, see this thread.

When I went to Workbench to change the validation rule the only rule that I found there was ‘^[\p{Graph} ]*$’

That really has no bearing on the number of allowed characters. Give you give me more detail regarding how to change this?

Thanks,
Todd
