jsf - Append CSS style from a bean -


is possible append style during @postconstruct of component, example commandbutton. change style class here no way because need dynamic values.

i tried following resets style of button

uiviewroot root = facescontext.getcurrentinstance().getviewroot(); commandbutton button = (commandbutton)root.findcomponent("form:btn1"); button.setstyle("background-color: red;");

you can assign style commandbutton dynamically using expression language: 

<p:commandbutton ... style="#{bean.buttonstyle}" ... />

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.
