Hi Cielpa,
'Invalid property' would suggest that your form does not contain the
property searchList. It is difficult to tell without a bit of background and
seeing some code. Can you explain what you are doing and show me your
struts-config.xml file.
By the way, your form should be declared as a DynaValidatorForm. There is no
such thing as a DynaValidatorActionForm.
For example..
<form-bean name="myForm" type="org.apache.struts.action.DynaValidatorForm">
<form-property name="searchList" type="java.util.ArrayList"/>
</form-bean>
