Additional Operators with FPM Search GUIBB

Hello everyone,

another question about the FPM Search GUIBB.

I have the requirement to implement a FPM Search GUIBB where the user can search for "relative dates" like today, yesterday, last week, last month, etc. To do so, I planed to add new operators (using attribute INCLUDE_OPERATOR of parameter ET_FIELD_DESCRIPTION_ATTR in feeder class method GET_DEFINITION). Everything works fine, however I would like to hide the value fields, when a relative date is selected. With standard search operator the value fields are controlled automatically. For example: When the "between" operator is selected, two value fields are shown. When the "is empty" operator is selected, no value fields are shown, etc.

Is such a controlling of value fields also possible with additional search operators?

Thanks in advance for your advices!
