Katie, You are doing only one thing wrong -- this is the developer's list, and usage questions should be addressed to the users list. For your question, the problem is not with the tags, but rather with your bean: In your scenario, the populate() method does the equivalent of
mainForm.getItemList(index).setItemName(name) Notice that it is getItemList(), _not_ setItemList(). To solve this, instead of private ArrayList _itemList = new ArrayList(); in the MainForm class, use import org.apache.commons.collections.ListUtils; import org.apache.commons.collections.Factory; class ItemBeanFactory implements Factory { // Make new BeanItem's } private ArrayList _itemList = ListUtils.getLazyList(new ArrayList(), new ItemBeanFactory()) ; And things might look better. Have fun, Shai. -----Original Message----- From: Katie Wright [mailto:[EMAIL PROTECTED] Sent: Thursday, July 31, 2003 20:41 To: '[EMAIL PROTECTED]' Subject: Help Please with usage of nested tags Hi, I am new to this mailing list (i.e. I am sorry if I do something wrong, please don't flame me). I am not new to struts but I am new to the more advanced tags. I have run into this problem. I think that I am close but just not understanding a key concept. I am trying to create an HTML form like so: Item1Label Item1Textbox Item2Label Item2Textbox Item3Label Item3Textbox What is new to me is the fact that in this case, the number of items vary and the item labels vary. I can display the page fine with the populated values for edit but when I try to do a save, I get the following struts exception: javax.servlet.ServletException:BeanUtils.populate at org.apache.struts.util.RequestUtils.populate RequestUtils.java:1254) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcess or.j ava:821) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java: 254) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482) It seems to be having trouble activating my setter in my form but not sure why. I think because I have setup something improperly but don't know what. I have done some research on the Internet and by following by example I have developed the following: <html:form action="MainFormSave.do"> <nested:iterate property="itemList"> <nested:hidden property="itemName" /> <nested:write property="itemName" /> <nested:text property="itemDescription" /> </nested:iterate> </html:form> I have a MainForm class which includes the following: private ArrayList _itemList = new ArrayList(); public void setItemList(int index, ItemBean item) { if (index < this._itemList.size()) { this._itemList.set(index, item); } else { this._itemList.add(item); } } public ArrayList getItemList() { return (this._itemList) ; } And I have an ItemBean which includes the following: private String _itemName = null; private String _itemDescription = null; public void setItemName(String name) { this._itemName=name; } public String getItemName() { return (this._itemName) ; } public void setItemDescription(String desc) { this._itemDescription=desc; } public String getItemDescription() { return (this._itemDescription) ; } Thanks in advance, Katie Wright (who is hoping that it is not something completely obvious) [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --- Confidentiality Notice: This email transmission may contain confidential or legally privileged information that is intended only for the individual or entity named in the e-mail address.
