Problem with enum (5.0) in Eclipse 3.1M5/M6
The code below compiles and runs fine with Codeguide.
In Eclipse the source does not compile.
I have tried to define the enum members as static and/or private
and some other variations of the source code,
but to no avail.
I have checked all settings in Prefernces/Java/Compiler
to be 5.0 compliant.
Any suggestions why this won't work in Eclipse?

public class XYZ
{
//...
// ERROR
public enum ItemType{DBL, INT, MEMO, TXT, DATE, BOOL, COMBO, NONE };
//...
public enum QMode //inner class //<< ERROR <<
{
EQUAL (1, " = "),
GREATER(2, " > "),
LESSER(3, " < "),
GREATEROREQUAL(4, " >= "),
LESSEROREQUAL(5, " <= "),
LIKE(6, " LIKE "),
BETWEEN(7, " BETWEEN ");
int f_qm; String f_sql;
// ERROR
public QMode(int qm, String sql ) {f_qm=qm; f_sql=sql;}
public String toString(){return f_sql;}
}//QMode
//...
}// XYZ end class

Below I write that the sample code would compile with javac.
Thats wrong: javac 1.5.0_01 also outputs an error as Oivier pointed out before:
command prompt> javac TestInnerClassWithEnum.java
TestInnerClassWithEnum.java:22: enum declarations allowed only in static contexts
public enum PublicEnum {ENE, MENE, MUH};
I'm getting really confused now, as i actually never saw this error before and
actuall program is running without problems.

Then we can consider this problem as closed.
We behave as javac does as far as I can tell.
Thanks for the report anyway,
Olivier
