I have an issue with GWT 2.9.0 ListBox#getItemText():
String name = listBox.getItemText(i);
The result is a string with extra spaces removed at the end.
Have anybody run into the same problem?
Browser - Chrome/Firefox(latest)

I think I found the reason. It's the JS Implementation of OptionElement#setText.
It discards the last spaces in the string. I see that in debugger.
Here method input parametr "String text" contains space symbol at the end.
But after executing the line "this.text = text;" ,
this.text contains string without space symbol at the end;
OptionElement.java:
/**
* The text contained within the option element.
*/
public final native void setText(String text) /*-{
this.text = text;
}-*/;
So do I need to replace all leading and trailing white space characters with " "?
OptionElement.java:
/**
* The text contained within the option element.
*/
public final native void setText(String text) /*-{
this.text = text;
}-*/;

This html example explains the source of problem.
I don't know why JS implementaion of ListBox doesn't mask space symbol with
It's a normal practic for JS implementations for GWT components?

And workaround is to encode all string put into/extracted from list with function:
Maybe this will help someone
private String encodeString(String s) {
StringBuilder sb = new StringBuilder(s.trim().replaceAll(" +", " "));
return sb.toString();
}
StringBuilder sb = new StringBuilder(s.trim().replaceAll(" +", " "));
return sb.toString();
}
Maybe this will help someone
