jsf 2 - ui:include value is evaluated before preRenderView -


page1.xhtml

<h:body> <h:link outcome="page2.xhtml> <f:param name="id" value="1"/> </hlink> </h:body>

page2.xhtml

 <h:body>     <f:metadata>     <f:event type="prerenderview" listener="#{mybean.init}"/>     </f:metadata>     <ui:include src="#{mybean.mystring}"/>     </h:body>

mybean.java

public void init(componentsystemevent e){   map<string,string> params =    facescontext.getexternalcontext().getrequestparametermap();   string myid = params.get("id");   int id = integer.parseinteger(myid);   if(id==1)     setmystring = "mypage.xhtml"; }

while navigating page1.xhtml page2.xhtml sending id parameter according id display page

the problem page cannot find

i printing in console what's happening found is evaluating getmystring() before going prerenderview init why happening this

i tried post construct returned error in resource injection of managedbean

that's classic view build time vs view render time problem: <ui:include> tag handler that's evaluated @ view build time, while <f:event type="prerenderview"> naturally called when view rendered. guess, latter event happens after former, while expect otherwise. still, when former tag requests evaluate attribute, it's null, or isn't there yet.

read classic jstl in jsf2 facelets... makes sense? better grasp @ what's relationship between these 2 phases of jsf lifecycle.

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
