I'm having problems with ELong. It sounds like there could be a bug. I had
posted this as a reply to a 2007 message but I thought I should post again
so that it appears on the top of the newsreaders. My ocl version is 1.1.2

thanks,

In ocl I specify a maximum value for a ELong field using a value which EInt
cannot store but
then get a parse error:

java.lang.NumberFormatException: For input string: "4294967295"
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)

When I specify a value which EInt can store I get the following exception at
runtime:

java.lang.ClassCastException: java.lang.Integer cannot be cast to

Hi, Arvinder,

A bug involving problems with handling long precision values was
addressed in the 1.2 release:

https://bugs.eclipse.org/198451

Does this look like your problem? Are you able to reproduce your
problem with the 1.2 release? It's worth the upgrade ;-)

HTH,

Christian
