selenium - Getting java.lang.ClassCastException while trying to access element in the list -


sample code:

public class {     list<webelement> itemlist = new arraylist<webelement>();     public list<webelement> getitemslist()     {         itemlist = (driver.findelements(by.xpath("<some valid xpath>")));         return(itemlist);     } }  public class b {     hp = new a();     public void subscribe()     {            hp.getitemslist().get(0).click();     } }

i creating list of webelements on page in class , in class b trying click on first element.

on execution getting below exception:

> java.lang.classcastexception: java.lang.stackoverflowerror cannot cast java.lang.exception

issues has thing findelements because when added elements using findelement method list manually in code, code working fine.

in below example have commented findelements line , instead added elements manually, code working fine.

public class {     list<webelement> itemlist = new arraylist<webelement>();      public list<webelement> getitemslist()     {         //itemlist = (driver.findelements(by.xpath(".//*[@id='hc6|stocks|item1']/span[2]"")));         itemlist.add(driver.findelement(by.xpath(".//*[@id='hc6|stocks|item1']/span[2]")));         itemlist.add(driver.findelement(by.xpath(".//*[@id='hc6|stocks|item2']/span[2]")));         itemlist.add(driver.findelement(by.xpath(".//*[@id='hc6|stocks|item3']/span[2]")));         return(itemlist);     } }

can suggests whats going wrong?

i tried xpath follows:

list<webelement> itemlist = driver.findelements(by.xpath(".//*[@class='itemrow button']/span[2]"));  // .//*[@class='itemrow button']/span[2]     system.out.println("list " + itemlist);

returned following elements:

i hope not problem xpath or findelements method. using framework writing tests?

in line:

 //itemlist = (driver.findelements(by.xpath(".//*[@id='hc6|stocks|item1']/span[2]"")));

observed additional double quotes present @ end of xpath span[2]"". check if reason error.

java.lang.stackoverflowerror occurs in case of recursive calls made. please code whether recursion happening.

java.lang.classcastexception: java.lang.stackoverflowerror cannot cast java.lang.exception

in catch block, used exception, code throws stackoverflowerror error (but not exception)

go through code thoroughly find out recursion happening.
