EP Fiori Framework Page Plugin: ffp.extensions LOAD_HOMEPAGE event not fired

Hi,

I created a Fiori Framework Page Plugin vor SAP Enterprise Portal. In my plugin I register a callback for the event LOAD_HOMEPAGE

sap.ffp.extensions.registerFFPExtension(sap.ffp.extensions.extensionTypes.LOAD_HOMEPAGE, function(groups) {...})

Have a look here for the documentation: https://help.sap.com/viewer/f2f3f4b4543a4803b9023e8c31f1e72a/7.5.12/en-US/95c96973b8484a6f83ab60142b81cc12.html

This worked fine on NW 7.50 SPS11 (sapui5: 1.52). After updating to NW 7.50 SP17 (sapui5: 1.71.15) the event is not triggered any longer.

Any ideas?

Thanks in advance
Helmut
