sorry for my spelling errors and bad English...
I dont need a vector of vectors, here is my code, just compile with make:
https://github.com/globularcluster/testeMSAIntObjVector
not that I can draw the vector with ofApp::draw(), but I believe that this is not the goal in use the ofxMSAInteractiveObjects.
ofApp()::drawPage1(2, 3...) will be used with the buttons, when it work 
thank you for the help, @zach
