[galaxy-dev] Displaying BED files in IGV

Hello - I am wanting to be able to display bed files from Galaxy in IGV. I have created a bed.xml display application description, and edited the datatypes_conf.xml to enable the igv display of datasets of bed format. However, when I select the link in Galaxy to "Display with IGV local" I get the following error message in Galaxy: You must import this dataset into your current history before you can view it at the desired display application. I am attaching my bed.xml file I created based off of existing IGV display types. I was hoping someone either has a working display descriptors for bed files for IGV, or might know what my error is. Thanks much, Ann
