This is probably the case for rules in addition to bpm.

kcbabo:bfitzpat: hey - quick question for you on the bpm properties sheet
[11:08am]kcbabo:the actions tab on the implementation
[11:08am]kcbabo:it seems like the variable value is not being displayed for inputs/outputs
[11:09am]kcbabo:and globals
[11:09am]kcbabo:if I click on it, I can see the value
[11:09am]kcbabo:and it's being stored in switchyard.xml
[11:09am]kcbabo:I should say "if I click on the variable cell"
[11:09am]kcbabo:but if the row is highlighted, there's no value displayd
[11:09am]kcbabo:displayed
