Data URL box includes an extra group when selecting the expression constraint for a variable

[kyang2014]

When going http://test.opendap.org/opendap/data/hdf5/grid_1_2d.h5.dmr.html

When you choose the variable temperature under /HDFEOS/GRIDS/GeoGrid/Data_Fields/temperature, select the expression constraint as temperature[0:2:3][0:1:7] and choose "NetCDF-4" with the "Get Data" box, you will see a group "/HDFEOS/ADDITIONAL" is automatically selected in the box as something like:
`

`

This group /HDFEOS/ADDITIONAL should not be part of the returned "Data URL".

See the attached screenshot.

Interesting! When anything in /HDFEOS/GRIDS is checked (selected via the associated check box in the form) the Group /HDFEOS/ADDITIONAL is also selected automagically. And once that happens the checkboxes associated with /HDFEOS/ADDITIONAL and it's constituents become in operable - they cannot be deselected (unchecked).

This is probably a bug in the javascript located in the file olfs/resources/hyrax/js/dap4_buttons.js, or in the XSL that builds the Data Request Form from the DMR: olfs/resources/hyrax/xsl/dap4_ifh.xsl
