Failed to render component
Giuseppe
Hi,
I've created an External Object for a component LS in a page (.page).
After the deploy on Runtime Enviroment I've noticed a problem,
sometimes in IE there is an Exception like this:
Failed to render component [1192626567938]
java.lang.RuntimeException: Failed to transform the component

Caused by: java.lang.NullPointerException
It seems that the Runtime does not find the class of External Object.
But if i try to refresh the page it works fine.....
Instead of in Firefox the component it seems ok....
thx bye

where's the rest of the stack trace the last line is:
Caused by: java.lang.NullPointerException
i don't see a class cast exception

My guess is you have bad initialisation your java code, crashes the first time around and then works alright because gets initialized or reset or something along those lines.
So check your code
