I should have mentioned the get(String, int) is called to get the business object (bean) from the array, so it can then set the property. Since the array is empty it fails with any index. The only solution I can see is to override this method or use LazyValidatorForm (LazyDynaBean). Is there a recommended solution?

TRUE or NOT TRUE? Chris, In my DynForm I'm actually using a java.util.ArrayList (contains my bean objects). the http request contains properties: checkList[0].resultId=34&checkList[1].resultId=45 etc I havn't debugged using a String[] but the BeanUtilsBean.populate method works differently with properties. I'm not sure the best approach to handle an empty arraylist, but the point is you still have to do *something* - I'm just not sure what. Dumb question: - assuming your String[] is empty when the processPopulate starts, what is the code to grow it to accomodate a variable number of http request parameters?

My setup in struct-config.xml: <form-bean name="questionSetForm" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="id" type="java.lang.String" /> <form-property name="name" type="java.lang.String" /> <form-property name="description" type="java.lang.String" /> <form-property name="addQuestionId" type="java.lang.String[]" /> <form-property name="deleteQuestionId" type="java.lang.String[]" /> </form-bean> Part of my form-handler action: // Add and remove the appropriate questions. List questions = getQuestionList(existingQuestions, questionSetForm.getStrings("addQuestionId"), questionSetForm.getStrings("deleteQuestionId")); If you are getting IndexOutOfBoundsException, then your loop might be running too long. How are you determining what the maximum index is that you can use? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org <http://enigmail.mozdev.org/> <http://enigmail.mozdev.org/> iD8DBQFFeXZH9CaO5/Lv0PARAk8cAKDAtrEWWH1nl34JU75mKkGfh+IPswCffh6X 56p3VYmREkJLNH5by0RVysM= =yUyl -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ********************************************************************** This message is intended for the addressee named and may contain privileged information or confidential information or both.
