The problem you're running into is that your form bean doesn't match the Bean pattern for indexed properties. In the populate method of the BeanUtil class a check for IndexedPropertyDescriptor is done on the form bean. The javadocs for IndexedPropertyDescriptor state:
... if the argument name is "fred", it will assume that there is an indexed reader method "getFred", a non-indexed (array) reader method also called "getFred", an indexed writer method "setFred", and finally a non-indexed writer method "setFred". So to have a "correct" Bean, you need two getters and two setters for an indexed property. One for the entire array and one for an individual element of the array. I've always though it is a bit confusing that the tags use the non-indexed reader while the BeanUtils use the index writer. That's how it will populate the page initially but not populate the bean on the post. Hope this helps bsr -----Original Message----- From: Alex Colic [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 05, 2002 3:20 PM To: Struts Subject: How to fill a String[] property-updated question.? Hi, just an update. Before I access the page I initialized the String[] array elements to 1...6. When I get to the page the values in the String[] array are properly displayed in the corresponding text boxes but when I submit the page I get the following error: java.lang.IllegalArgumentException: array element type mismatch at org.apache.struts.util.PropertyUtils.setIndexedProperty(PropertyUtils.ja va:8 51) at org.apache.struts.util.PropertyUtils.setIndexedProperty(PropertyUtils.ja va:7 85) I don't understand why I can view the elements but not save the elements. Thanks for any info.
