provide background info on "The path of an ForwardConfig cannot be null"
------------------------------------------------------------------------
Key: STR-3094
URL: https://issues.apache.org/struts/browse/STR-3094
Project: Struts 1
Issue Type: Improvement
Affects Versions: 1.3.8
Environment: linux, j2se v1.6
Reporter: Ralf Hauser
this happens for example if the action in a html:form tag is not existing in
the struts-config.xml
A reasons for this could be due to a typo.
Suggestion: if the ForwardConfig lookup in struts-config.xml results in "null",
please cite the action string that was used for the lookup .
The below error message is currently not particularly helpful. Or at least
mention something like, "please check your struts-config.xml"
