Mapping nodes

You access and maintain mappings through the types of node listed below:

When you are debugging mapping nodes, the flow debugger allows you to step into mappings and step over mappings. Unlike ESQL or Java debugging, you cannot set breakpoints on the code.

When you want to debug a flow with mappings, set a breakpoint at the connection right before the mapping node. Then, in the flow debugger, when the flow pauses at the breakpoint, you can step into the code, and then step through it (step over) line by line. You can also examine the mapping routine that is being executed, and view variables.

This uses a combination of two perspectives: the Flow Debug perspective and the Debug Perspective. The workbench switches automatically between the two perspectives as required when you select the various debugging actions (and you can also switch between them yourself).
