onValidate() gets called for every form component inside your form. The NullPointerException you are
getting is likely due to some other form component also validating. Change the method name to match

Hello!
We are using the upload component of tapestry and want to validate the
content type during the upload. To accomplish this we wrote the
following code:

| private UploadedFile file;

| void onValidate() {
|
| if(file.getContentType().toLowerCase(Locale.ENGLISH)
|
