android - AbsListView: ClassCastException inside onRestoreInstanceState during screen orientation change -


i'm using abslistview in several fragments , activities can use listview in portrait mode , gridview in landscape. of daily testing in ics , jb, , works fine. started testing on gb devices (2.3.6), , classcastexception when rotate device 1 of these screens active. here's stack trace:

05-09 14:04:55.019: e/androidruntime(6052): caused by: java.lang.classcastexception: android.widget.listview$savedstate 05-09 14:04:55.019: e/androidruntime(6052):     @ android.widget.abslistview.onrestoreinstancestate(abslistview.java:1018) 05-09 14:04:55.019: e/androidruntime(6052):     @ android.view.view.dispatchrestoreinstancestate(view.java:6325) 05-09 14:04:55.019: e/androidruntime(6052):     @ android.view.viewgroup.dispatchthawselfonly(viewgroup.java:1314) 05-09 14:04:55.019: e/androidruntime(6052):     @ android.widget.adapterview.dispatchrestoreinstancestate(adapterview.java:767) 05-09 14:04:55.019: e/androidruntime(6052):     @ android.view.viewgroup.dispatchrestoreinstancestate(viewgroup.java:1301) 05-09 14:04:55.019: e/androidruntime(6052):     @ android.view.view.restorehierarchystate(view.java:6304) 05-09 14:04:55.019: e/androidruntime(6052):     @ android.support.v4.app.fragment.restoreviewstate(fragment.java:417)

since view of different type depending on orientation, saving state isn't necessary. disabling via setsaveenabled remove control onsaveinstancestate/onrestoreinstancestate events.

    list = (abslistview) findviewbyid(r.id.list);     list.setsaveenabled(false);

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
