Re: Newbie help with For and TextField components

Hi Daniel, thanks very much for this, it makes things much clearer (best explanation of it I've seen by a long chalk!). I'll take your advice and create a holder object for my string that uses a UUID to identify the strings. Thanks! jim Daniel Tabuenca wrote: Eventually I'm going to be s

Re: Newbie help with For and TextField components

Eventually I'm going to be saving the values in RDF - the values won't have a persistent key, they're just literal values. I'm also keen to avoid using any session persistence but will do if it's necessary. Can tapestry deal with simple values that don't have identity in this way? To understand

Re: Newbie help with For and TextField components

Well it's because you are using strings directly. Here's what the equivalent of what is going on in JAVA: List names = NAMES; for( String name : names ){ name = " NEW VALUE FROM INPUT FIELD"; // but strings are immutable so name has a new string reference and does not modify // the one that is

Re: Newbie help with For and TextField components

I don't get it. What are you trying to do? You aren't persisting your list anywhere so at each render or rewind your lists starts off null. so by the time it gets to the @For loop the @For loop has nothing to iterate over. Am I missing something? On 1/9/07, Jim Downing <[EMAIL PROTECTE
