CALT works fine with Indesign NOT Illustrator

I’ve added a few special MARKS to my font as a CALT feature … it works fine with Adobe Indesign; Unable though to operate them in Illustrator.
Is there something I miss in the feature code or is a bug reported in Adobe Illustrator ?

InDesign supports CALT; Illustrator supports SALT; only Adobe knows why. You will need both in your font.
