Renato,
There is another solution that is clean.
We use one action class with multiple (3) mappings to support our
validation needs. With our editor scheme, the user proceeds to a Top
page where they decide to Edit an existing or Add a new item. They then
proceed to a Detail page where
Hi Sudhakar,
Your JSP should populate the form fields in the same way for both add and
modify actions. Specifically, your action class should initialize the form
for the jsp. When the page is rendered, it will be populated the way that
you want.

Ted,
The origin of this thread had to do with using Indexed Properties and a
Dyna* form. As when using the ActionForm, getting the values to the
browser is not an issue. The area where the difficulty arises is when the
values are returned from the browser.
When using the ActionForm (or
into your form (formName.selectedItems[0].fieldName) then
Struts should
handle the rest.
Does that help at all?

The reason you get the null pointer exception is that the inventoryList
property in your DynaActionForm is created empty. The exception occurs
when Struts tries to populate inventoryList[0].startNumber or
inventoryList[0].endNumber.
Even though I haven't used the DynaActionForm, I know that

You can find examples of this by searching the archive for indexed
properties. You are getting this exception because the Form collection
does not have enough entries to support the property that you are trying to
populate. You need to insure that the getter that returns a single bean

I have done something similar to this. I haven't looked at browser

Hi Rajat,
You could use an Array. If your form is in the session, as opposed to the
request, the array will never go away, so the array will retain its size.
I can't do that in our app as our UI presents a spreadsheet and allows
the user to add and remove rows. For that reason, I use an

Take a look at the mail archive. There are at least two threads that I

Would the bean:define tag meet your needs? The value is available for

Alternatively, you might consider extending the hidden tag for your needs.

Are you sure that your request attributes are named that way? I read that

I looked at your code, and it looks right. It makes me think that
something must be wrong with the data. Your data should look like this:
- You have an object called Results in scope that has a collection property
called tabledata (tbdata).
- Each object in the tbdata collection

ActionClass.
The weird thing is that the first iterate works fine - for the column
headings.
And the outer loop in the second iterate works too. It will print out
the collection in cell one of the tabledata for example.

Look at the way that you have named your ColumnNames property in the jsp

getColumnNames and setColumnNames. We've had seen that problem a couple

I have a similar function where I allow the user to view the contents of
various DB tables in my system. My process works like this:

collection of column

See the thread from 7/28-7/30 titled inxeded properties. Everything you

Atta,
You can use indexed properties in your ActionForm class. The key is having
all of the correct methods in your form class.
1) Getter and setter: You need a get/Set method for the collection that
you refer to in your jsp. for example:
public Collection getLocations()
public void
with the fact that my individual fruit is a string
object rather than being a bean in itself if some getter method(s)?
can you see what's going wrong!
Thanks again.
