Debugging Techniques

Debugging LiveCycle workflows can be tricky. This document gives a short introduction to some of the techniques that we find useful.

h3. Variable Logger

User a VariableLogger at various steps in your process to find out the real values of your process variables. 

h3. Println

Use the Script component, with the following code, so that you at least know where your process has gotten to:
{code}
System.out.println("Yay, my process has gotten to step 12");
{code}

h3. Database

If you're using a long-lived process, the values of all your process variables are stored in the database. Use a database query tool to go any find the values of your variables.

You can even change the values of variables, and continue your process. But be careful that you don't corrupt anything.

The table name is: tb_pt_<Your process name with punctuation and spaces removed>

h3. Bypass routes, Start node

Sometimes the bit of the process you want to test is the 47-th step of the process. You don't really want to have to go through 7 approval steps, just to get to the part of the process where you're flattening the form.

An easy way to avoid this is to temporarily put in a "bypass" route, that skips all the approval steps, and fast-tracks your process directly to the bit you're having problems. Another way is to temporarily set the start-node to a node further along the process.

h3. Logging Levels

You can bump up the Log4J logging levels in the application server log files to get extra information on what's going wrong.
