> Hello,
> I have been trying to get validation working with dynamic method invocation, using ActionName-aliasName-validation.xml files.
> When the struts.property is set >> struts.enable.DynamicMethodInvocation=true, in the DefaultActionMapper the mapping name is changed by removing !submit from the action eg fieldValidatorsExamples!submit becomes fieldValidatorsExamples. When the validator tries to find FieldValidatorsExampleAction-fieldValidatorsExamples!submit-validator.xml it cannot, as the validator is looking for FieldValidatorsExampleAction-fieldValidatorsExamples-validator.xml. But this is now not linked to a method.
> {code:java}
> if (allowDynamicMethodCalls) {
> // handle "name!method" convention.
> String name = mapping.getName();
> int exclamation = name.lastIndexOf("!");
> if (exclamation != -1) {
> mapping.setName(name.substring(0, exclamation));
> mapping.setMethod(name.substring(exclamation + 1));
> }
> }
> {code}
> With struts.enable.DynamicMethodInvocation=false, validator works but method name is null.
> This line of code is causing the problem mapping.setName(name.substring(0, exclamation));. Without this line seems to work but I am no expert!
> eg:
> {code:xml}
> <action name="fieldValidatorsExamples!*" class="org.apache.struts2.showcase.validation.FieldValidatorsExampleAction" method="{1}" >
> <result name="input" type="dispatcher">/validation/fieldValidatorsExample.jsp</result>
> <result type="dispatcher">/validation/successFieldValidatorsExample.jsp</result>
> </action>
> {code}
> {code:html}
> <s:form action="fieldValidatorsExamples!submit" namespace="/validation" method="POST" theme="xhtml">
> <s:textfield label="Required Validator Field" name="requiredValidatorField" />
> <s:textfield label="Required String Validator Field" name="requiredStringValidatorField" />
> <s:textfield label="Integer Validator Field" name="integerValidatorField" />
> <s:textfield label="Date Validator Field" name="dateValidatorField" />
> <s:textfield label="Email Validator Field" name="emailValidatorField" />
> <s:textfield label="URL Validator Field" name="urlValidatorField" />
> <s:textfield label="String Length Validator Field" name="stringLengthValidatorField" />
> <s:textfield label="Regex Validator Field" name="regexValidatorField"/>
> <s:textfield label="Field Expression Validator Field" name="fieldExpressionValidatorField" />
> <s:submit label="Submit" />
> </s:form>
> {code}
> Cheers Greg
