java - Obtaining list views in Jenkins from nested view plugin -

i have developed plugin has extension point listviewcolumn have run problems when combining plugin, nested view plugin . my plugin enables 1 select jobs in current view , make modifications 1 button press. when view resides inside nested view, can't find view (from java code , jelly scripts) , no modification can made. in columnheader.jelly execute ${it.getheadertext(view.name)} where getheadertext() defines as public string getheadertext(string viewname) { hudson.getinstance().getview(viewname); // access jobs return object of .getview(viewname) return viewname; } this works fine regular list views whenever enter nested view's list view, getview(viewname) returns null. upon further investigation i've noticed nested views show when calling hudson.getinstance().getviews(); which returns views in toplevel of whole jenkins instance (no views inside nested views). here have nested view shows , instance of hudson.plugins.nested_view.nestedview.

pandas - Python: Automatically choose parameters for ARMA model -

i trying fit arma model time series data. haven't find functions can automatically choose parameter. below code wrote beginner python hence believe code can optimised. can give me ideas on how to: do vectorization on double loop quicker way parameter choosing much appreciate. parameter_bound = 3 # creating 2-d array, storing residuals of 2 different parameters of arma model residuals = [[0 x in range(parameter_bound)] x in range(parameter_bound)] model = [[0 x in range(parameter_bound)] x in range(parameter_bound)] # calculate residuals each parameter combinations in range(parameter_bound): j in range(parameter_bound): model[i][j] = sm.tsa.arma(input_data, (i,j)).fit() residuals[i][j] = sum(abs(model[i][j].resid)) # find parameters lowest residuals parameters = np.argmin(residuals) parameter1 = parameters/parameter_bound parameter2 = parameters - parameters/parameter_bound*parameter_boun

how can we merge two java objects in one xml file? -

this program. correct way merge 2 objects? public class objecttoxml { public static void main(string[] args) throws exception{ jaxbcontext contextobj = jaxbcontext.newinstance(employee.class); marshaller marshallerobj = contextobj.createmarshaller(); marshallerobj.setproperty(marshaller.jaxb_formatted_output, true); try{ employee employees = new employee(); employees.setemployee(new arraylist<employee>()); employee emp1=new employee(1,"vimal jaiswal",50000); employee emp2=new employee(2,"kamal",40000); employees.getemployee().add(emp1); employees.getemployee().add(emp2); marshallerobj.marshal(employees, new fileoutputstream("e:\\employee.xml")); } catch(jaxbexception e){ system.out.println(e); }}} its giving output doulbe times: 1,"vimal jaiswal",50000 2,"kamal",40000 1,"vimal jaiswal",50000 2,"kamal",40000 please find below code solve problem,
