Hi; When a tool has conditional changes in output format, the workflow designer does not recognise the conditional output types. i.e. if the standard output is tabular, but one of the tools settings changes it to interval, you cannot then connect the oiutput node to a tool requiring an interval data type. The workflow designer still treats the other tools output as tabular, even though it should now be interval Is this something that is easily fixed?
