Re: Compare two string-type PVs in CSS/BOY rule

["Hu, Yong via Tech-talk" <tech-talk at aps.anl.gov>]

pvStr0 == “some text” works in the old CS-Studio/BOY (4.5.1) too.

The problem I had is about comparing two string-like PVs: pvStr0 == pvStr1 does not work in 4.5.1; however, String(pvStr0) == String(pvStr1) works.
Does pvStr0 == pvStr1 work in CS-Studio/Phoebus?

Thanks,
Yong

    Rule expressions
       pvStr0 == “some text”
    work in the latest incarnation, i.e. the Display Builder in CS-Studio/Phoebus.
    I assume that's in part because BOY would internally translate the rules into JavaScript, while the Display Builder translates them into Jython.
