Hi
I want a float parameter which is optional, so the field displayed to the user is blank, and validated as float if user enters a value, i try this:
<param name="abc" type="float" optional="True" value="" label="a number" />
but get the "A real number is required" error.
Looking in the code, "class FloatToolParameter( TextToolParameter )" in http://bitbucket.org/galaxy/galaxy-central/src/tip/lib/galaxy/tools/paramete... it seems like the optional parameter handling is missing.
Cheers
