occassional NoMethodError after creating new model object

rubyonrails-talk

This seems to happen every so often, where I have code similar to the following:

new_model_obj = Foo.new new_model_obj.someParam = someVar

And I get the following error:

<NoMethodError> undefined method `someParam=' for #<Foo >

This code normally runs fine with no problems, the Foo object clearly has that attribute and this code works 95% of the time. The strange thing I noticed is that in the error msg, #<Foo > does not have a hex address location like it normally would. If I intentionally try to create this error by calling new_model_obj.blah where I know blah is not an attribute, I get an error msg that looks like this:

<NoMethodError> undefined method `blah' for #<Foo:0x476321c>

Anybody have any ideas why this would occasionally happen? Any help would be greatly appreciated as I am thoroughly stumped.

Thanks
