Re: [S2] Indexed Lists
Hello , I am trying to get the textfield list working (in parallel to the check boxes) but couldn't ?? the function I set to be called is never called after the submit. I know that the values in the textfiels are sent, and the setter function for the Checkboxes (setConfigs) is called but not the function for the textfields (setConfigsList) ??? I assument that this setter should have String[] for argument as well ? can you please explain what this function look like in order to be invoked ? thank you Roger Varley wrote: > > On Friday 12 September 2008 16:18:02 Jeromy Evans wrote: > >> >> In the last line, did you confirm that count has the correct value? >> What if the list is empty?

In the last line, did you confirm that count has the correct value?
What if the list is empty? (in that case count has never been set)
The issue could relate to how valueables is being constructed. Are you
creating it, or leaving it to the framework to create it? It should be
able to add extra elements to a list
For added entertainment, could anyone point me to a dojo/javascript tutorial
that would allow me to add a further empty line when ever the user completes
an empty line without, if possible, submitting the form? Or someother
technique that allows the addition of unknown number form fields?
in pure javascript:
var inputEl = document.createElement("input");
inputEl.type ="input";
inputEl.name ="valueables["+count+"]";
var parentEl = document.getElementById("thePositionId");
parentEl.appendChild(inputEl);
and so on. or
parentEl.innerHTML = "";
and so on.
where count is an argument passed to your function (eg in response to a
click in the next empty row)
You'll find plenty of tutorials along those lines. The latter approach
is faster but vulnerable to more browser querks.
Good javascript libraries include function to make the DOM manipulation
less verbose.

At the moment the list has three entries pre-loaded in my action which numbered 0,1 &2 by the iterator and the count evaluates to 3. > What if the list is empty?

Moving the code into a separate class and lo & behold I can now add to the list when it's pre-populated - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
