[Qgis-developer] SIP 4.18 and ConvertToSubClassCode

[Sandro Mani]

Hi

Fedora has updated to SIP 4.18, and I'm now seeing some issues with 
subclass conversions, in particular

composerView.composition().getComposerItemById("aQgsComposerLabel")

does not anymore return a QgsComposerLabel instance, but rather a 
QgsComposerItem instance.

Does anyone familiar with SIP know how to debug this? I've tried playing 
around with the ConvertToSubClassCode code in qgscomposeritem.sip, in 
particular changing sipClass with sipType (having read that the former 
is deprecated [1]), but no improvements. I actually don't even see that 
code executing by setting a breakpoint in sip_corepart0.cpp.

So, any ideas?

Thanks

Sandro
