java - String cannot be applied to com.org.apache.xpath.internal.operations.String -


i'm trying create piechart in javafx, , want fill data hashmap.

here's code:

public graph(hashmap<string, double> chartdata) {     observablelist<piechart.data> piechartdata = fxcollections.observablearraylist();      (map.entry<string, double> entry: chartdata.entryset()) {         string s = entry.getkey();         new piechart.data(entry.getkey(), entry.getvalue());         //system.out.println("key = " + entry.getkey() + ", value = " + entry.getvalue());     }      chart = new piechart(piechartdata);     chart.settitle("imported fruits"); }

the issue facing when try use entry.getkey() string, following error:

data (java.lang.string, double) in data cannot applied (com.org.apache.xpath.internal.operations.string, double).

the string marked red , when replace entry.getkey() "some text" work. cause?

you seem have imported wrong "string" class ( com.org.apache.xpath.internal.operations.string) in current file , data class expects correct 1 (java.lang.string). make sure imports correct (i.e. remove import of first type).

also see this question, asker has run similar problem

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.

everyone! i'm trying deal eclipse rcp 3.x application. i've read lot of articles dependency injection in rcp e4 applications. can use di in rcp 3.x apps? i found perfect link di in e4. idea how use in rcp 3.x app? first of all, i'm interested in own objects injection (btw, how add own object application context?). best regards in 3.x code can ieclipsecontext necessary use contextinjectionfactory using ieclipsecontext workbenchcontext = platformui.getworkbench().getservice(ieclipsecontext.class); to workbench context. in view or editor can current part context using: ieclipsecontext partcontext = getsite().getservice(ieclipsecontext.class);
