what process , update in primefaces p:commandxxx components , execute , render in f:ajax tag? which works @ time of validation? update attribute rather updating value component end? process attribute bind value model? @this , @parent , @all , @form in both attributes? the example below working fine, little confused in basic concepts. <p:commandbutton process="@parent" update="@form" action="#{bean.submit}" value="submit" /> <p:commandxxx process> <p:ajax process> <f:ajax execute> the process attribute server side , can affect uicomponent s implementing editablevalueholder (input fields) or actionsource (command fields). process attribute tells jsf, using space-separated list of client ids, components must processed through entire jsf lifecycle upon (partial) form submit. jsf apply request values (finding http request parameter based ...

i maintain scroll position when using: response.redirect(request.rawurl) the reason because have button in gridview updates value in grid. after clicking button want update value in gridview, needs response.redirect(request.rawurl) want maintain scroll position. this not work either: maintainscrollpositiononpostback="true" i have tried other javacript methods , not work well, since refreshing page. how this? i fixed it. i replaced response.redirect(request.rawurl) gridview1.databind()

android lets extend application , great place store our singletons can reused throughout different pages (actiivities) in app. what google app-engine's equivalent of this? i using dagger, , don't want create new object graph every endpoint. one option (although i'm no means sure it's best) self-inject cloud endpoints class (through static field injection). presumably you're initialising object graph in servletcontextlistener there, before endpoint methods called. dagger 1.x supports staticinjections on module annotation (to you) apparently no longer supported in 2.x.

i want write stream method may need ignore several concurrent values based on "lastgoodversion" can't find way share value within stream. below i'd do. suggestions on how accomplish this? [edit don't this, it's not how java streams work] i don't think possible using java 8 streams. possible solution want use helper function may this: private static <t> stream<t> progressivefilter(stream<t> stream, bipredicate<t, t> predicate) { list<t> list = stream.collect(collectors.tolist()); list<t> result = new arraylist<>(); t previousvalue = null; (t entry : list) { if (previousvalue == null) { previousvalue = entry; } else { if (predicate.test(entry, previousvalue)) { result.add(previousvalue); } else { previousvalue = entry; } } } i...

i writing x86 interpreter in java , have python script tests implementations of x86 instructions against real counterparts using nasm. according test flags set correctly, besides carry flag. interesting part is: long result; switch (op) { case add: result = math.abs(x) + math.abs(y); if (result > u_max) registers.carry_flag = true; else registers.carry_flag = false; break; where u_max 4294967295l (all 32 bits set). answers found didn't realize carry , overflow 2 different things. so, how can implement carry flag correctly in java? all absolute value business unnecessary , frankly confusing , has edge-case math.abs(integer.min_value) negative (not weird when down it, doesn't code expects it), can calculate carry in simpler ways . for example using old "result unsigned less 1 operand". result of course x + y (as int ), signedness irrelevant addition. java 8, can use integer.compare...

i want display 1 more same confirmation pop on click of yes button not working, code : $.confirm({ text: "are sure want delete ?" confirm: function() { $.confirm({ text: "we going delete ?" confirm: function() { }, cancel: function() { } }); }, cancel: function() { } }); i'm using jquery-confirm.js this. i need alternative implement functionality or solution problem. as @pmandell said, configuration object invalid. need commas after each attribute of javascript object so: $.confirm({ text: "are sure want delete ?", confirm: function() { $.confirm({ text: "we going delete ?", confirm: function() { }, cancel: function() { } }); }, cancel: function() { } });
