Search help unavailable in Read-only input field since EHP4

Dear Experts!

I have a problem with a Portal page since the deploy of the EHP4. The page has standard input fields with Search Helps. I needed to have the input field non-modifiable so the user would have to use the search help to get the proper information.

Prior to the EHP4 installation, I set the input field to Read Only in the WebDynpro explorer, this disabled the editing while permitting the user to use the Search Help.

Since the installation, the search help is no longer visible or accessible on a Read Only standard inputfield.

Do you know if there is a way to allow the search help on a read only field?

Thanks so much for your answer,

Brian Foster.
