I have experienced similar bugs in the 7.1 component editor. If I re-edit some of my components, signals and interface properties changes from what I originally defined. I haven't got any NullPointerExceptions though.

One example is a component with an avalon-slave interface that always re-opens with it transformed to an "interrupt slave" interface. No settings for it are available in the interface tab. In the message box all signals get the error/warning

"signal signalname has unknown type". However the TCL-file seems alright after the first time saving the component interface definition. It generates and synthesizes fine. (If no re-edits are made)

Only way to be sure everything is the way I want, is to manually check and edit the *_hw.tcl file.
