Re: Validation of indexed properties
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 Hugh Cielpa wrote: Hey, I have a similar problem with DynaValidatorActionForm. It says that invalid property when i have a ArrayList in the form-property name=searchList type=java.util.ArrayList/ in the form-bean declaration. Any idea? Thanks and your help is appreciated.

Re: Validation of indexed properties
Sorry Cielpa, my mistake. Turns out there is such a thing as a DynaValidatorActionForm. Shows how much I know.
