I build an image using Hob successfully (yeah!) then save it as a template. Later, I launch hob again and click Templates to load up my saved template. I was surprised that it still wanted me to select a machine. Why wasn't the machine saved in the template? It should be remembered. Well, being tricky, since I was prompted for a machine, I changed it (from qemux86_64 to qemumips) and got tons of error messages. Once you reload a template, the machine should get selected to what was saved in the template.
Because the tar ball of the beta program is using very old poky, after bisecting, http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=ea8a7a82da8fa1fa3ff89877fa31dad33407d734 on March 15 has fixed the issue while its previous commit a957dbd0a92642362757a9af3660f693851d9b5c still has the issue. I still can't reproduce that on the lastest poky master.
