Problem with float binding..Spec issue or something else?

[Mert Çalışkan <mc...@gmail.com>]

I have a domain object called Total that contains property named amount.
*
package* domain;

*public* *class* Total {

    *private* *float* amount;

    *public* *float* getAmount() {
        *return* amount;
    }

    *public* *void* setAmount(*float* amount) {
        this.amount = amount;
    }
}

The amount proerty is binded to the inputText on the page. When the user
enters value greater then 2^14(16777216) the updated model value becomes
inconsistent. For example the value: 16777217 is converted and updated to
the model as 16777216. Here is the shale test case i wrote to test the
situation. There is an assertNotSame() method at the end of the testCase
which should be an assertSame().

		inputText.processUpdates(facesContext);
		
		Total amountFromModel = (Total)
facesContext.getApplication().getVariableResolver().resolveVariable(facesContext,
"myTotal");
		String amount =
inputText.getConverter().getAsString(facesContext,inputText, *new*
Float(amountFromModel.getAmount()));
		
		assertEquals(amount, "16.777.216");
	}

facesContext.getApplication().getVariableResolver().resolveVariable(facesContext,

		String amount =
inputText.getConverter().getAsString(facesContext,inputText, *new*
Float(amountFromModel.getAmount()));
		
		assertNotSame(amount, "16.777.217");
	}}


I tested this with jsf 1.1_02. Any ideas? Is there a problem with the spec.
or something else?
