[BioC] problem with nsFilter and hthgu133a format eset

[Fraser Sim]

Hi,

I am having a problem running the following code which utilizes an eset
derived from hthgu133a CEL files.

>eset
ExpressionSet (storageMode: lockedEnvironment)
assayData: 13834 features, 9 samples 
  element names: exprs, se.exprs 
phenoData
  sampleNames: <<masked>>  (9 total)
  varLabels and varMetadata description:
    sample: arbitrary numbering
    CEL: NA
    phenotype: NA
    ShortName: NA
featureData
  featureNames: 1007_s_at, 1053_at, ..., AFFX-r2-Ec-bioD-5_at  (13834 total)
  fvarLabels and fvarMetadata description: none
experimentData: use 'experimentData(object)'
Annotation: hthgu133a

>library(genefilter)
>nsF = nsFilter(eset, var.filter = FALSE)$eset
Error in .checkKeys(value, Lkeys(x), x at ifnotfound) : 
  value for "AFFX-BioB-3_at" not found'

loaded via a namespace (and not attached):

The code works as expected using an eset derived from hgu133plus2 CEL files.

Cheers,
