The Pipeline tab shows all variables that the service placed in the pipeline, not just those that were declared in the service’s input/output parameters.

Variables that a service explicitly drops from the pipeline do not appear on the Pipeline tab.

When you select a variable in the Pipeline tab, Designer displays details about the variable value in the details panel in the lower half of the Pipeline tab. For array variables, Designer displays the index number and position for each item in the array. You can copy and paste values from the details panel in the Pipeline tab.

You can browse the contents of the Pipeline tab, but you cannot edit it directly. However, if you debug a flow service, you can edit the contents of the pipeline. For more information, see Modifying the Flow Service Pipeline while Debugging.

You can save the contents of the Pipeline tab to a file and use that file to restore the pipeline at a later point. For additional information about saving and restoring the contents of the Pipeline tab in the Results view, see Saving the Results and Restoring the Results.

When a failure occurs within a Java service, the Pipeline tab represents the state of the pipeline at the point when that Java service was initially called. If the Java service made changes to these values before throwing the exception, those changes will note be reflected on the Pipeline tab.

If you run a flow service and an error occurs, the Pipeline tab will only show results up to the point of the error.

Variables with object types that Designer does not directly support will appear in the Pipeline tab, but because Designer cannot render the values of such objects, a value does not appear in the Value column. Instead, the Value column displays the object’s Java class message.

Variables that contain com.wm.util.Table objects appear as Document Lists in the Pipeline tab.
