another problem current code quite long, want short have tried change code , doesn't work.

current code:

<f:selectitem itemlabel="afterdark" itemvalue="afterdark" />               <f:selectitem itemlabel="afternoon" itemvalue="afternoon" />               <f:selectitem itemlabel="afterwork" itemvalue="afterwork" />               <f:selectitem itemlabel="aristo" itemvalue="aristo" />               <f:selectitem itemlabel="black-tie" itemvalue="black-tie" />               <f:selectitem itemlabel="blitzer" itemvalue="blitzer" />               <f:selectitem itemlabel="bluesky" itemvalue="bluesky" />               <f:selectitem itemlabel="bootstrap" itemvalue="bootstrap" />               <f:selectitem itemlabel="casablanca" itemvalue="casablanca" />               <f:selectitem itemlabel="cupertino" itemvalue="cupertino" />               <f:selectitem itemlabel="cruze" itemvalue="cruze" />               <f:selectitem itemlabel="dark-hive" itemvalue="dark-hive" />               <f:selectitem itemlabel="delta" itemvalue="delta" />               <f:selectitem itemlabel="dot-luv" itemvalue="dot-luv" />               <f:selectitem itemlabel="eggplant" itemvalue="eggplant" />               <f:selectitem itemlabel="excite-bike" itemvalue="excite-bike" />               <f:selectitem itemlabel="flick" itemvalue="flick" />               <f:selectitem itemlabel="glass-x" itemvalue="glass-x" />               <f:selectitem itemlabel="home" itemvalue="home" />               <f:selectitem itemlabel="hot-sneaks" itemvalue="hot-sneaks" />               <f:selectitem itemlabel="humanity" itemvalue="humanity" />               <f:selectitem itemlabel="le-frog" itemvalue="le-frog" />               <f:selectitem itemlabel="midnight" itemvalue="midnight" />               <f:selectitem itemlabel="mint-choc" itemvalue="mint-choc" />               <f:selectitem itemlabel="overcast" itemvalue="overcast" />               <f:selectitem itemlabel="pepper-grinder" itemvalue="pepper-grinder" />               <f:selectitem itemlabel="redmond" itemvalue="redmond" />               <f:selectitem itemlabel="rocket" itemvalue="rocket" />               <f:selectitem itemlabel="sam" itemvalue="sam" />               <f:selectitem itemlabel="smoothness" itemvalue="smoothness" />               <f:selectitem itemlabel="south-street" itemvalue="south-street" />               <f:selectitem itemlabel="start" itemvalue="start" />               <f:selectitem itemlabel="sunny" itemvalue="sunny" />               <f:selectitem itemlabel="swanky-purse" itemvalue="swanky-purse" />               <f:selectitem itemlabel="trontastic" itemvalue="trontastic" />               <f:selectitem itemlabel="ui-darkness" itemvalue="ui-darkness" />               <f:selectitem itemlabel="ui-lightness" itemvalue="ui-lightness" />               <f:selectitem itemlabel="vader" itemvalue="vader" />

i tried:

<f:selectitems value="[afterdark, afternoon, afterwork, aristo, black-tie, blitzer, bluesky, bootstrap, casablanca, cupertino, cruze, dark-hive, delta, dot-luv, eggplant, excite-bike, flick, glass-x, home, hot-sneaks, humanity, le-frog, midnight, mint-choc, overcast, pepper-grinder, redmond, rocket, sam, smoothness, south-street, start, sunny, swanky-purse, trontastic, ui-darkness, ui-lightness, vader]" var="theme" itemlabel="" itemvalue=""/>

and

<f:selectitems value="#{themeswitcherbean.themes}" />

i tried above 2 , doesn't work.any idea?

why using treemap store themes , list them? in example linked, must use list instead of map in <f:select> tag

in themeswithcherbean.java

private list<theme> themes;  @postconstruct public void init() {     themes = new arraylist<theme>();     themes.add(new theme(0, "afterdark", "afterdark"));     themes.add(new theme(1, "afternoon", "afternoon"));      // , many more }

and results in view dropbox.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
