Snippet with Splitter - odd behavior

[pierrelabreche]

When inserting a snippet containing split branches, I observed an odd behavior : The split branches appear to have been serialized, instead of being inserted in parallel.

Refer to attached screen capture.
I created the snippet from the workflow tree shown on the left, and inserted it on the image to the right.

I did not design snippets to work with splitters so I am not surprised they behave strangely. At a minimum, it should give you an error message. Anyway, I will take a look at what it would take to make this work for some future release.

As an aside, in the example you present, you could easily get the correct result by selecting just the top level image and then cloning the entire branch which will then let you load a new top-level image for the cloned branch.

In this example, if I select a branch with splitters, and insert copies of the selected transformations , everything works as expected.

However, if a stored snippet is executed, it does not work.

It does say in the help file than snippets may not include splitters or branches. I looked at the code and adding this would be complicated, however I did add code to check for this case and provide an error message.
