This is discovered when in WindowTabField, in the Field Tab, at the Display Logic control, you can only do "equals to" and "not equals to", missing on the "greater than" and "less than" stmts.

I contributed this in version 250 but now in 251e it still isnt there. So here it is again. Go to MField.java in your Eclipse, and put in these two snippets.
You can also pick up the whole code here http://compiere.red1.org/MField.zip. Its is version 251e, fully commented with usage example.

private boolean evaluateLogicTuple (String logic)
{
//red1 -- init Float variables to handle string Evals in < > comparisons
float f1 = 0; //red1
float f2 = 0; //red1
StringTokenizer st = new StringTokenizer(logic.trim(), "<>!=^", true); //red1 <> added here

=====================2nd snippet a bit lower ===========

// Logical Comparison
boolean result = firstEval.equals(secondEval);
if (!compare.equals("="))
result = !result;
//
// red1 -
if (compare.equals(">"))
{ result = false;
f1 = Float.parseFloat(firstEval);
f2 = Float.parseFloat(secondEval);
if (f1>f2)result = true;
}
//red1 --
//red1 - if compare '<'
if (compare.equals("<"))
{ result = false;
f1 = Float.parseFloat(firstEval);
f2 = Float.parseFloat(secondEval);
if (f1<f2)result = true;
}
//Set in WindowTabColumn, Field Tab, DisplayLogic example:"@thisField@>99 | @thisField@=99"
//red1 -- thisField is firstEval, 99 is secondEval -- end
if (Log.isTraceLevel(10))
Log.trace(10, "MField.evaluateLogicTuple - " + logic + "=> \"" + firstEval + "\" " + compare + " \"" + secondEval + "\" => " + result);
//
return result;
} // evaluateLogicTouple

Here's a message reply from Compiere, that this bug is fixed. So what u ppl can do is to reload the latest MField.java from sourceforge and see how it is properly done. Should be fun to compare between a true pro and me as a dummy All in good jest!

Initial Comment:
I fixed a bug in MField.java so that it can handle display
logic comparisons 'greater than' and 'less than'.

When u go into WindowTabColumn, Field tab, Display
Logic column, u can only specify '!', '=' when the Help
notes said u could also do >,<.

Now it can. Using Floats to evaluate.
Done on version251e.

Fully commented //red1.

1>2 .. numbers
1>AA .. strings
0>0.0
