[galaxy-user] Order of input files when creating a workflow.

Hi, Just wanted to report this to see if there any way to keep the order of the input files when creating a workflow. When I create a workflow starting with 4 input files. I named then 1,2,3,4 respective in that order from top to bottom. However when try to run the workflow I get a random order of the files. For example the first time I get from bottom to top 3, 1, 4 ,2. And the order changes every time I try to re order them in the workflow. Thank for your feedback. Victor
