Hi,

Can you please have a look at the following code to figure out why my customer JSpinner throws a runtime "java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.lang.Integer" error ?

The Javadoc for the SpinnerNumberModel constructor you're calling says


All of the parameters must be mutually Comparable, value and stepSize must be instances of Integer Long, Float, or Double.

You'll need to create your own version of SpinnerNumberModel. Fortunately the source is available in the src.zip file inside your JDK folder.

Hi Guys,

I tried Ernest's path and used the constructor with Comparables but this time it started throwing casting exceptions about Byte and BigInteger which told me that I have to go either in the src from JDK or do my own stuff.

Thanks Rob, that was a good advice, generating another class for this feels a bit of an overkill but totally made sense compared to this "casting chaos".

Thanks and cheers,

Ulvi
