[IDV #JYJ-451577]: IDV v2.9a1: Loading bundles without data source specified



Hi Dave-

When the Field Selector opens, it shows the fields that have the correct 
category for the type of display.  In this case, the gridded point data fields 
are not being categorized correctly, so they don't show up.  We'll look into 
this.  For now, you can select the Formulas->Misc->Any Field which will then 
allow you to select the SPD variable. 

Nice display.  I like the dotted contour lines.

> 
> To see if you can replicate this behavior, I've attached a copy of the
