[Bioc-devel] NAMESPACE and GOstats summary

hgOver <- hyperGTest(params)
summary(hgOver)

Hi,
I am the mantainer of oneChannelGUI package, which is a graphical
interface to some Bioconductor packages.
I am working on the implementation of NAMESPACE for my package.
I am actually having problems in using the summary for object
GOHyperGResult from the GOstats package.
If I call the summary for an object generated by the function
hyperGTest without using the NAMESPACE
hgOver <- hyperGTest(params)
summary(hgOver)
I get as output a data frame as expected.
However, if I add the namespace to my package:
import(GOstats)
exportPattern("^[^\\.]")

When I execute:
hgOver <- hyperGTest(params)
summary(hgOver)
I get as output
Length          Class           Mode
             1 GOHyperGResult             S4

It seems that I did not load the summary method.

I also tried to import the summary method modifying the NAMESPACE in
the following way:
import(GOstats)
importMethodsFrom(GOstats, summary)
exportPattern("^[^\\.]")

But I get the following warning during compilation:
Warning message:
In namespaceImportFrom(self, asNamespace(ns), allVars, allFuns,  :
  Found methods to import for function "condGeneIdUniverse" but not
  the generic itself

and I do not get the data frame ether.

Any suggestions how to handle this problem?
Cheers
Raffaele
