OWB package import error. PRS-00318. In need of urgent help

Question

Hello everyone,
I am having a weird error when i try to import a package in owb. Saying "PRS-00318: SQL Error encountered while updating CMPALLFOLDERFCO for key ********************************* Please contact Oracle Support with the stack trace and details on how to reproduce it. " ( neglect the ** i didnt want to write that bit )
This started to happen a couple of days ago. When i try to import a package or re-import them it seems like the procedures in the packages all seems like they are requiring a parameter ( i understand it in the import window, the paranthesis after the procedure name like procudre_name( ) ) But actually there is not a parameter required for the procedure to work. It is not declared at all. When i hit the import button it gives me the error below.

Well i have no idea what is going on. Even the existing packages ( that are imported long before this error ocurred ) are showing the procedures with parameters.
Anyone having any idea how to solve this problem ?
Your help would be appreciated.

Answer 1

finally sorted it out! it had something to do with the ArrayCollection in the mx.collections not being linked to the AS hence the error. so heres what i did:
import mx.collections.ArrayCollection;
import flash.net.registerClassAlias;
registerClassAlias("flex.messaging.io.ArrayCollection", ArrayCollection);
i imported the ArrayCollection class and the registerClassAlias class into the AS i was using and then registered the alias then voila! error gone!
