The build was failing before CodeBlocks 11783 but is working since then.
The additional patch does not fix building but fixes 11783 which enables editing of elements which should not be editable simply because 11783 forgot to change these elements accordingly. I hope this clears the confusion.
1) wxparentproperty.patch + wxschart.patch -> Fix building by using readonly parent property
2) wxs-1-composed.patch -> Fix buildind by using composed parent property
1) and 2) are mutually exclusive, you applied only half of 1), the other half is missing
