When the PropertyPanel is calling addSection() and there are no actual property components to add (an empty section), the the constuctor of SectionComponent() asserts when using the OwnedArray::addArray() method
data.ensureAllocatedSize (numUsed + numElementsToAdd);
jassert (data.elements != nullptr);
that didn’t happen before, did something change ? is it mandatory now to have property components within the PropertyPanel ?
