i have following jsf radio button: 

<h:selectoneradio id="journeydir"   value="#{refparam.journeydir}">   <f:selectitems value="#{newmessage.journeydirectionselectitemlist}" />     </h:selectoneradio>

the values of radio button, can selected user defined in java method:

public list<selectitem> getjourneydirectionselectitemlist() {     final list<selectitem> journeydirectionselectitemlist = new arraylist<selectitem>();      journeydirectionselectitemlist.add(new selectitem(journey.bidirection,             yes));     journeydirectionselectitemlist.add(new selectitem(journey.oneway, no));      return journeydirectionselectitemlist; }

now have problem, first value of radio button, declared in java method above, selected automatically load jsf webpage. have requirement, no values must selected automatically system.

how can solve problem? ideas? use jsf 1.2.

just make sure journeydir variable set null

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
