Hello all, in my form i have a String[] which i fill using html:text tags. However when i reach the action in which i need the String[] it is null. What can i do to resolve this?

I'm not exactly following what you mean that you have a String[] in your form?

Are you saying that you have multiple textfields that all have the same name?

yes i have a String[] that compares to multiple text fields in the jsp. When i go into the action i guess the form resets and the String[] is null.

Name of the String [] and name of that HTML element should be same or getting the value in the action . Are you using the same name ???

Ok situation now is as follows :

I have two action : one that initializes a shoppingcart and one dispatchaction that updates, deletes etc. In my form i have a map which contains key : product id and value is a String object containing the amount.

my form contains the following methods :




In my JSP i have the following code :


This works for displaying purposes. So it shows the correct amount. Question is though what can i do to update the amounts. When it reaches the action the map is null. Perhaps place the map in the request, but is it then possible to write to the given object using html:text tag.

Does anyone know how to deal with this issue???
