I'm here to report a bug of CodeWarrior for MCU 10.7.
The bug occurs in DSC projects when the "Customize linker input order" checkbox is checked in "C/C++ Build -> Settings -> Tools Settings tab -> DSC Linker -> Link_Order".
When the aforementioned checkbox is checked, Trying to switch to "C/C++ Build -> Settings -> Tools Settings tab -> DSC Linker" causes a nullpointer exception and the tab content sometimes is not refreshed, sometimes it is only partially drawn.
After unchecking the ckeckbox, the error disappears.
This problem does not affect builds, but it prevents from editing the tab content when the error window appears.
I hope this will be helpful for future updates
