Subject Re: Multiple Logic iterate tags and setting indexed properties
Date Tue, 14 Apr 2009 23:37:10 GMT

Hi Nikhil,

Thanks for the suggestion. I tried, but it is still not working. I am using
struts tags and instead of <input>.
If my class structure was like the below one, then the values will be
updated without any problem when the form submitted. The problem comes when
I have two logic iterates(as shown in my earlier post).

class BookList
	String bookListName
        boolean selected

class BookInfoForm extends ActionForm{
	ArrayList<BookList> bookLists;
	
	public BookList getBookl(int index){
		return bookLists.get(index);
	}
	public void setBookl(int index,BookList element){
		bookLists.set(index, element);
	}
	
}

<logic:iterate name="bookInfoForm" id="bookl" property="bookLists"
indexId="i">

<html:checkbox name="bookl" property="selected" indexed="true" value="true"
/>
<bean:write name="bookl" property="bookListName" />

</logic:iterate>


Thanks,
Thanuja
