# Kluge to fix the Extended Choice Parameter.
#
# ECP's "text box" mode, for whatever reason, was hardcoded to use a
# 200-pixel-wide entry box. Using absolute values in HTML rendering
# sizes is almost always wrong; in this case it means the box will
# be about 30 characters wide – painfully small if the parameter
# value is intended to be a path.
#
# Luckily, this can be fixed by changing one text file inside the
# plugin's jar, replacing that "width:200px" with "width:100%".
# This value will use as much space as the parent rendering element
# is willing to give it.
#
# Caveat: Pasting this into Jira may have glitched some line breaks...
#
# Debug trace, if desired
