When you add multiple Blob VCF sources, the same blob is displayed twice

[danvk]

Here's what my sources array looks like:

var sources = [
    {
      name: 'Genome',
      twoBitURI: 'http://www.biodalliance.org/datasets/hg19.2bit',
      tier_type: 'sequence'
    },
    {
      name: 'VCF1',
      tier_type: 'memstore',
      payload: 'vcf',
      // uri: '/snv.vcf'
      blob: new Blob([vcfBytes1])
    },
    {
      name: 'VCF2',
      tier_type: 'memstore',
      payload: 'vcf',
      // uri: '/snv2.vcf'
      blob: new Blob([vcfBytes2])
    }
];

When I comment out the blob keys and uncomment the uri keys, I see the expected result:

But when I use blobs, I see the same thing twice:

I can verify that vcfBytes1 != vcfBytes2.

The Blob support is really expecting File objects, not generic blobs. Try setting the name property on your blobs to (different) strings and all should be well.

I'll tweak the caching code so that it doesn't assume blobs with no names are all the same!

I can verify that vcfBytes1 != vcfBytes2.
