Ralf Hauser commented on STR-3094: ---------------------------------- besides the typo, there is a second reason how this can happen: a form gets posted to a perfectly valid url, but in org.apache.struts.chain.commands.AbstractSelectInput.execute() no "input" is found if erroneously, in the struts-config, the validate="true" it would be good to report about this fact in an error message too! > 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 > Fix For: 1.4.0 > > > 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.
