My goal is to enable a FME user to select certain trajectories of waterways, on basis of attribute values, prior to executing the Workspace for the selected trajectories.
I accomplished to define a User Parameter that has as type "Choice (Multiple)". By importing the input file I could also select all the (unique) attribute values to take them into account as a valid choice.
Using a Tester I make a simple Test Clause to select the trajectory by setting it equal to the User Parameter.
If I now select a single trajectory, the Workspace is successfully executed. If I however select multiple trajectories as User Parameter, no trajectories will pass the Test Clause and the FME Workspace will not be executed accordingly.
My guess is that the User Parameter stores the trajectories as a list, and that the Test Clause for some reason is not selecting the trajectories individually but attempts to find trajectories equal to the the list of trajectories.
Does anyone have an idea how to solve this problem?
Kind regards,
