In the attachment you can find two files: - model.xml is a workflow - scr1.png is a screenshot from workflow execution The screenshot shows also the tooltip displayed on output port of expression actor. There is "arrayType(general)", but according to input array types and an excerpt from expression evaluator, it should be "arrayType(string)". However I found out today that it can work with cast() function: cast(arrayType(string), concatenate(t1, t2)) Yesterday I wrote, that cast() did not help, but I made a mistake. Sorry for misleading you with this. But still - is this behaviour without cast() correct and expected? Best regards, Tomek -- Tomasz Zok Poznan Supercomputing and Networking Center ul.
