Version 0.13 Unable to search across multiple tracks

[xiuchengquek]

Hi writing in to address an issue with using more than one searchable tracks with biodalliance version 0.13

When I have 2 searchable source

 sources:     [{name:                 'Genome',
                   uri:                  'http://www.derkholm.net:8080/das/hg18comp/',
                   tier_type:            'sequence',
                   provides_entrypoints: true},
                  {name:                 'Genes',
                   desc:                 'Gene structures from Ensembl 54',
                   uri:                  'http://www.derkholm.net:8080/das/hsa_54_36p/',
                   collapseSuperGroups:  true,
                   provides_karyotype:   true,
                   provides_search:      true
                  },

                  {name:                 'Repeats',
                   uri:                  'http://www.derkholm.net:8080/das/hsa_54_36p/',
                   stylesheet_uri:       'http://www.derkholm.net/dalliance-test/stylesheets/ens-repeats.xml'},
                  {name:                 'MeDIP raw',
                   uri:                  'http://www.derkholm.net:8080/das/medipseq_reads'},
                  {name:                 'MeDIP-seq',
                   uri:                  'http://www.ebi.ac.uk/das-srv/genomicdas/das/batman_seq_SP/'},
                  {name:                 'test-search',
                   bwgURI:                  'https://pwbc.garvan.org.au/~xiuque/capseq_data/out.bb',
                   provides_search:      true,
                  }
   ]

This results in the following error ( from the console )

Uncaught TypeError: source.features is not a functionBrowser.doDasSearch @ dalliance-all.js:13360(anonymous function) @ dalliance-all.js:13351Browser.search @ dalliance-all.js:13353(anonymous function) @ dalliance-all.js:2482

However when i switch to the source of my biodalliance to version 0.11 at http://www.biodalliance.org/release-0.11/dalliance-compiled.js

I can search by both the gene track and the test-search track that I have added.

The content of out.bb in bed format is a bed file with a single feature
