Problem with Dynamic text boxes

[bi...@tcs.com]

hi
 i have to display a screen in which the no of rows are dynamic. in each 
row there are 2 text boxes where user can enter values.
 after entering the values in the text boxes user press 'SAVE'  button . 
in the Action form  i have to validate the values in the validate() method 
. also 
in the Action class  there will be some data processing. 

but how can i use get(),set() methods of the Action form,as the no of rows 
are not fixed.

i am trying to avoid the request.getParameter('Field name'); in the Action 
form or in Action Class.


Any Suggestion! 

Thanks

You might also want to use indexed properties.
Look into the indexed=true flag on the html taglibs.

in your action form you can do this.

String text1[];
string text2[];

public void setText1(String text[]) text1 = text; }
public void setText2(String text[]) text2 = text; }
public String getText1() {return text1; }
public String getText2() {return text2; }


validate() {

if (text1.length != text2.length) {
//save this error here.
}
else {
   //loop through arrays validating each pair.
   //and saving appropriate errors. 
}

Your form should take a Collection or an array of beans.. where each 
bean then has the text fields you are concerned with. (ie SomeBean would 
have get/set methods for the two text names). Think of each row 
reprenting a bean.

Then you just loop over the Collection, pull out the bean each time and 
create your two text fields. When you submit Struts will automagically 
populate all your beans correctly.
