[ BUILD # : 200510301900 ]
[ JDK VERSION : 1.5.0_04 ]

For builds 200510261858 & 200510301900 , when editing javascript areas of jsp's when you type a dot eg document.images , it triggers code completion (not normally present for javascript) and you get a class cast exception.

Within a javascript area just type abc. and you get the crash when you hit ok on the crash box everything is ok until you type the next dot.

I can recreate on both solaris and windows across these two builds of NB , with the beta and other builds typing a . in a javascript area is ignored/no suggestions.

In my testing it only affects .jsp files , .html and .java were fine 

The classcast exception follows and I will attache messages log after
