data association converts date + duration expression to a string
Summarydata association converts date + duration expression to a string
While the simple expression builder considers the following date arithmetic expression to be valid, the data association window shows that the express is being converted to a string and thereby considers it invalid:
date('now') + duration("PT"+hoursDO+"H")
Meanwhile, the data association window is perfectly happy with these:
'now' + 'PT1H' date('now') + duration('PT1H')
Some screen shots to add context...
I have come up with a not very desirable workaround, but I'd like to be able to do this in a single expression like above. Any help/thoughts appreciated!
