java snippet editor imports broken? [message #727904]

Hi,

I'm getting to grips with the Eclipse/Java "total beginners tutorial" and on lesson 3 I'm finding that the operation of Eclipse deviates from the video.

I have (apparently) successfully set the imports for myScrapbook.jpage to org.totalbeginner.tutorial.* and when I put the period after the p I do get a selection box including the four methods that were defined in the prior lesson. But when I attempt to inspect p, this is what I get :-

The method setName(String) is undefined for the type Person
The method setMaximumBooks(int) is undefined for the type Person
Person p = new Person();
p.setName("Fred");
p.setMaximumBooks(3);
p

This is with Eclipde 3.7 downloaded and installed this week on WinXP.

This is a showstopper. All help appreciated!

Imports in java snippet editor works for me. Do you have another 'Person' class in that project?

I do not - but I have spotted something that seems very relevant, if inexplicable.

Here's the class :-

package org.totalbeginner.tutorial;

public class Person {
// fields
private String name; // name of the person
private int maximumBooks; //most books the person can check out

//constructors
public Person() {
name = "unknown name";
maximumBooks = 3;
}

// methods
public String getName() {
return name;
}

public void setName(String anyName) {
name = anyName;
}

public int getMaximumBooks() {
return maximumBooks;
}

public void setMaximumBooks(int maximumBooks) {
this.maximumBooks = maximumBooks;
}
}

However, in the left margin of the pane there are warning triangles against the two lines :-

private String name; // name of the person
private int maximumBooks; //most books the person can check out

and the warnings that pop up say these fields are never read locally.

Hav I gotten some invisible corruption in the ASCII, I wonder?

I made the warning disappear by cutting an pasting the whole pane across to MS notepad and back, but it has *not* cured the ;inspect' problem on the snippet editor

Maybe I should just start over.
