## I just started having this problem today. Some of my buttons, instead of going to their respective screens, will come up with a serialization error. Here is the text from the error message.

I do not know what is causing the problem. I also dont know if it is related to the fact that I can not seem to open the FPMI designer.

Any ideas, thoughts or suggestions greatly appreciated.

Thanks.

Java 7 is likely your problem. FPMI, and even earlier versions of Ignition, have issues with serialization on Java 7. Revert to Java 6 and report back 🙂

The JNLP file specifies which java version to run with.

By default (with my installation at least) on the system config page it specified the java versions as “1.6+;1.5+”.

Changing this to “1.6;1.5+” fixed the JNLP and made FPMI run under java 6 instead of java 7 and made me look like a genius.

Hopefully this will help others…
