java - struts2 populate "value" object of map from Form post -

-

i'm using struts 2. have object contains booleans. have hashmap contains many of previous objects defined key.

in jsp table populated radio buttons. 1 line each key of map etc. when post form want save options set user. map not seem populated.

my code like:

   myobject ( 2 boolean parameters )      private map<string, myobject> ... (with getter & setter ).

in jsp html generated is:

    <input type="radio" name="mymap[123].booleanparameter1" id="someid"  checked="checked" value="true">  etc

can on how "name" of radio button should set struts can populate map?

public class myobject implements serializable{      private boolean booleanparameter1;     private boolean booleanparameter2;  getters & setters here } 
map<string,myobject> mymap ... in action

jsp...

 <s:iterator ...iterates default map values>   <s:radio label="parameter1" name="mymap['%{key}'].booleanparameter1" list="#{'true':'yes','false':'no'}" value="%{value.booleanparameter1}" /> <s:radio label="parameter2" name="mymap['%{key}'].booleanparameter2" list="#{'true':'yes','false':'no'}" value="%{value.booleanparameter2}" />  </s:iterator>

solution found. class "myobject" did not have default constructor. struts/ognl needs default constructor create object.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (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...
