| We should never get here. |

| <#attempt> |
| Let's try to output an undefined variable: ${undefinedVariable} |
| <#recover> |
| Well, that did not work.<@assert test=.error?contains('undefinedVariable') /> |
| Now we nest another attempt/recover here: |
| <#attempt> |
| ${sequence[1]} |
| <#recover> |
| Oops...<@assert test=.error?contains('sequence[1]') /> |
| Remember, freeMarker sequences are zero-based! ${sequence[0]} |
| </#recover> |
| Now we check the current error message.<@assert test=.error?contains('undefinedVariable') /> |
| </#recover> |
| <#attempt> |
| <#include "nonexistent_template"> |
| <#recover> |
| The template is not currently available |
| </#recover> |
| <#attempt> |
| <#include "undefined.ftl"> |
| <#recover> |
| The included template had a problem.<@assert test=.error?contains('undefined_variable') /> |
| </#attempt> |
