T5 : Editable Select
Dear all, I need to make an editable select box : i.e the user can either chose one of the option in the select box or type a custom String. Is it possible to make something like this with Tapestry 5?

Hi,
I want to create a very simple select list from an enum.
t:select model=${reportModel} value=${report}/
But in a select component, the model (org.apache.tapestry.SelectModel)
is required, I try to use EnumSelectModel but it did not work...
I can't have my enum list...
please help, thanks
Tom

RE: T5: onchange event from a select
Hello, this solution will submit the form, but 'onchange', I need to modify the value of the other select instead of submitting the form Martin CarstenM wrote: Hello, well, I dont know if its a nice solution but I realized it with several forms. Then you can handle the form event and update your second select box. t:select onchange=this.form.submit();/ Cheers, Carsten martin boulanger wrote: Hello, I have the same need, but I don't know how to make it.

T5 - Upload File Component : NullPointerException
Hello,
I would like to upload a file using a tapestry form. I have followed the
example presented here:
http://tapestry.apache.org/tapestry5/tapestry-upload/
HTML :
t:form
t:errors/
input t:type=upload t:id=file validate=required/
br/
input type=submit value=Upload/
/t:form
JAVA :
public class UploadExample
{
private UploadedFile _file;
public UploadedFile getFile()
{
return _file;
}
public void setFile(UploadedFile file)
{
_file = file;
}
public void onSuccess()
{
File copied = new File(/my/file/location/ +
_file.getFileName());
_file.write(copied);
}
}
But when I try to access the page, I get a java.lang.NullPointerException.
And I don’t understand which variable should be initialized.
I used FileUpload 1.2
org.apache.tapestry.ioc.internal.util.TapestryException
location
classpath:… / UploadExample.html, line 13, column 65
body
t:form
t:errors/
input t:type=upload t:id=file validate=required/
br/
input type=submit value=Upload/
/t:form
/body
java.lang.NullPointerException
