i've got few text-input helper this {{input type="text" valuebinding="name" focus-out="focusoutname"}} i upgraded ember 1.11.0 , deprecation warning: deprecation: you're attempting render view passing valuebinding view helper, syntax deprecated. should use value=somevalue instead. however when using value not bound in controller , value sets text whatever value. how correctly bind it? you should have change: {{input type="text" valuebinding="name" focus-out="focusoutname"}} to: {{input type="text" value=name focus-out="focusoutname"}} or better (don't need type="text", it's automatic): {{input value=model.name focus-out="focusoutname"}} then next can display value, , see change when change input (so can test bindings set already): {{input value=model.name focus-out="focusoutname"}} {{model.name}}

it unclear (to me, @ least) documentation whether activity.onstop guaranteed called. there 2 places seemingly contradictory information. javadoc activity.onstop: note method may never called, in low memory situations system not have enough memory keep activity's process running after onpause() method called. documentation (in particular 'killable' column) activity class http://developer.android.com/reference/android/app/activity.html#activitylifecycle : starting honeycomb, application not in killable state until onstop() has returned. impacts when onsaveinstancestate(bundle) may called (it may safely called after onpause() , allows , application safely wait until onstop() save persistent state. it's bit of struggle find way both pieces of documentation telling truth. scenario can think of this: suppose developing on target api 21 (with min sdk 10) , write activity onstop() method. if run application on api 10 phone, onstop() not guaranteed call

i aware of vh/vw or wmin/vmax units. still can't scale font whether width or height changes. is, can scale font using css in 1 case - if want scale font when width changes, use vw, height vh. there can use both cases? for both cases can use css logic: width:100vw; height:50vw; max-height: 100vh; max-width: 200vh; i believe there vmin , vmax. vmin unit equal smaller of ‘vw’ or ‘vh’. vmax unit equal larger of ‘vw’ or ‘vh’. via http://www.w3.org
