Re: Dynamic form fields on ActionForm
I just did this, maybe an example will help Read the database and stuff the data into an arraylist. Stuff the arraylist into the form. Call the page and get something like this tr td class=datainput type=checkbox name=feelistinfo[0].associated value=Y checked=checked class=checkbox/td td class=datainput type=text name=feelistinfo[0].feeTypeDescription value=Application Fee/td td class=datainput type=text name=feelistinfo[0].price value=1300.0/td /tr tr td class=datainput type=checkbox name=feelistinfo[1].associated value=Y class=checkbox/td td class=datainput type=text name=feelistinfo[1].feeTypeDescription value=Appraisal Fee/td td class=datainput type=text name=feelistinfo[1].price value=0.0/td /tr change the data and submit.. Back in the action you can access the array in your form and loop through the values returned. Watch out for the checkboxes though since they dont return a value unless checked. If you want the detailed code for the different pieces let me know. --- Adam Hardy [EMAIL PROTECTED] wrote: They're indexed! 0 becomes 0, 1 becomes 1 etc., i.e. the order they went out with remains the same when they come back in.

Re: Dynamic form fields on ActionForm
I guess my question about order was more of HTML/submit question than a question about arrays. I just want to guarantee that the order of the values being sumitted stay in the order they are on the page. I was simply giving every input field the same name such as product and catching the values in a String array in the ActionForm. I needed to worry about sort order in order to associate the values to their ids. Great example, I didn't think of creating an array of object like you to keep all of the data on one record together. --- Lynn Guy [EMAIL PROTECTED] wrote: I just did this, maybe an example will help Read the database and stuff the data into an arraylist.

Re: Dynamic form fields on ActionForm
Adam, I missed the point about adding the index to the input field name. I was simply naming the field the same thing. It actually worked, but it worried me.

Dynamic form fields on ActionForm
I am wondering what is the best approach to handle dynamic form fields within an ActionForm. I have a JSP page that will display quantity input fields for a dynamic list of products. I don't know how many products will be in the list until runtime. How can I set up my ActionForm to handle the list in input parameters?

Re: Dynamic form fields on ActionForm
Hi Cornellious, it depends whether you know beforehand what the full set of possible fields could be, or whether the fields themselves are not limited in name or type. If the former, then it would be easy to make a form that defined them all, and to use logic tags to display the needed fields or not in JSP.

Re: Dynamic form fields on ActionForm
Indexed form property is what you want.. I'll avoid any clever
explanations, grandiose meta language or to try and sell you a book..
And give you an example..
form-bean name=productForm
form-property name=product type=java.util.ArrayList /
..
action name=productForm path=/products scope=session...
...
DynaActionForm theForm = (DynaActionForm) form;
ArrayList productList =
theForm.set(product,productList);
//and for some stange reason.. try without the following first
session.setAttribute(product,productList);
...
logic:iterate id=product name=productForm property=product
html:text name=product property=price /
...
DynaActionForm theForm = (DynaActionForm) form;
ArrayList productList = (ArrayList) theForm.get(product);
for(int i = 0;i productList.size();i++) {
Product prod = (Product) productList.get(i);
System.out.println( prod.getPrice() );
}
...
This should help.. Cheers Mark
