Setting value to a readonly attribute using :Calculated Values" not working in RTC 4.0.5

We have a "Script Based Calculated Value" which sets value to a "readonly" attribute

This feature was working fine in RTC 4.0.2. After upgrading to RTC 4.0.5, the script is unable to set values to readonly attribute. Always throws error 

CRRTC0299E: The work item with the ID 43215 cannot be saved because an attempt was made to change the attributes '[Task Completion Percentage]' which are not modifiable.
" [Task Completion Percentage] " is the attribute (custom)

If I make this field as writable, then the script works.

Are there any changes between 4.0.2 and 4.0.5 ?

How can I make this work in RTC 4.0.5?

Is the attribute itself read-only, or is the presentation in the editor read-only?  I think you would need the attribute itself to NOT be read-only but have the Editor Presentation be read-only.

I'm only on 4.0.0.1, but I have one calculated value and the attribute is not R/O but the presentation has it as R/O.

Yea, I can't comment on that part of it.  I would say that there was a bug in 4.0.2 and they fixed that bug since if I say the whole attribute is read-only, then I wouldn't expect that RTC should allow programmatic changing of that attribute.

Thanks Susan. Looks like this will work for me!
