(more can read here: https://github.com/nwjs/nw.js/wiki/differences-of-javascript-contexts ). however, solved similar problem making separate js file setting button change page. index.js: document.getelementbyid("button").onclick = function(){ window.location.href = './otherpage.html'; } make sure require method not used in same js file change context. then load html file. index.html: <script src="./path_to/index.js"></script> hope helps. feel free ask questions or elaboration. tr...

in playframework 2.2.x, got error when trying binding form data pojo. illegalstateexception: no value and here sample code: form<orderrequest> form = new form<orderrequest>(orderrequest.class); final orderrequest orderrequest = form.bindfromrequest().get(); this article meant leave trail people suffer similar problem. i answer myself later. i wonder caused problem decided find out parameter might trigger problem. here structure of orderrequest: public class orderrequest { private int num; private boolean isadmin; private string name; .... } i able narrow down 2 parameters, turned out when input parameter [num] null, doesn't recognize null type int , parameter [isadmin] type boolean , for these primitive data type, not nullable type. to avoid situation, suggest checks type of each parameter, making sure setting value matches type. as mentioned, primitive data type not nullable type. one thing replacing primitive data type w...

imagine have make file subdirectories built using "make -c". image have 4 target directories. 3 out of 4 done, 1 needs run. run overall makefile with: make -j 4 is there way tell makefile system run remaining target make -c -j 4 instead of 1 ? if 2 targets missing make -c -j 2 each one. i'll expand on beta's (correct) answer. individual make processes communicate each other , guarantee there never more n jobs running across different make invocations, when use -jn . @ same time, guarantee (assuming there @ least n jobs can possibly run across make invocations), n jobs running. suppose instead had 4 directories "something do", somehow know priori, , instead of invoking 1 instance of make -j4 , letting make invoke 4 submakes normally, force each of submakes invoked -j1 . suppose first directory had 10 targets out of date, second had 5, third had 20, , fourth had 100 out of date targets. @ first have 4 jobs running in parallel. once se...

i have expandable listview child view, when ever click on group view expand , display child view, have hide divider between parent , child expanded group make visible when collapse, using default divider, how can this.? here perfect solution. to hide child divider set color transparent #00000000 define transparent in color.xml file <color name="transparent">#00000000</color> and set child divider listview.setchilddivider(getresources().getdrawable(r.color.transparent)) or in layout xml file <expandablelistview android:layout_width="fill_parent" android:layout_height="fill_parent" android:childdivider="#00000000"/> here output : for more detail visit here. android: hide child dividers in expandablelistview
