In my grails project, I'm getting "unable to resolve class Xxxxx" error messages.  

I'm seeing this for two situations:

1. the missing class is a Java class in the src/java folder and the error is showing up in the groovy class which 
references the Java class.  The groovy source file doesn't show any errors, the compile status indicator on the top 
right is green, but the Tasks list shows the error messages.  It could be a refresh problem in the Tasks list.

2. the missing class for the second case is when it's not able to resolve a command object that was declared inside 
controller (A) and used in a different controller (B).  I think the parser doesn't think that command object's scope 
should allow controller (B) to see the command object. When this application runs, controller (B) is able to use that 
referenced command object.  (this groovy behavior seems strange coming from the java world if that was an inner class)
