RE: Logic:iterate and html:text problem
Well, a) I have not used logic:iterate for these purpose, hence won't be able to help you out much there. I use the JSTL tags and try to keep away from the struts tag as much as possible. b) I would use ArrayList instead of Vectors. What I would do if I were you would be something like this: I have added the table just for clarity. You may want to put a check for empty or null collection doing either In case you already have this bean Or having another method like getSize() or something like that. Assuming that you have set and set methods on each one of the above three parameters in your MultipleIdData bean. Try this and see if the vales get populated in the Collection when you get it in your Action from the form. This may contain some errors but should get you started :) -Original Message- From: Anna Yates [mailto:[EMAIL PROTECTED] Sent: Monday, January 19, 2004 11:21 PM To: [EMAIL PROTECTED] Subject: Logic:iterate and html:text problem I have multiple text boxes that I display on my page. Basically, I must show n rows (2 text boxes per row). I have no problem displaying them, but I am unclear on how to get the data back in a concise manner. To display, I use logic:iterate (see below): logic:iterate name="custAcctForm" id="multiple" property="multipleIds" bean:write property="profileName" name="multipleIds" html:text property="userName" name="multipleIds" html:text property="password" name="multipleIds" In my form I have a Vector defined, private Vector multipleIds; The Vector holds a collection of my class, MultipleIdData which has 3 member variables: profileName, userName, and password. When I use the code above, it displays correctly, but the entered data goes nowhere. I have tried to define the "id" property to the "multipleIds" value, but it gives me an error that no collection was found. I was thinking I could index the values, but am unclear if this is the road I should take. I have seen that if I initialize the Vector to some initial capacity, this will work, but I don't know how large this Vector will be. Does anyone have any suggestions.

RE: Logic:iterate and html:text problem
but I don't know how large this Vector will be One trick is to submit the size back in a hidden field. In the forms reset() method, you can use request.getParameter() (unless its a multipart form!) to get the size and initialise the vector before the form is populated from the request. Id suggest however that since you have two two fields per row you may as well use nested form beans for each row rather than vectors for each column. (Also makes it much more convienient to add a third++ column later on if you need to.)
