MulitFileUploadField looses state after validation error
Hi everyone
Little advice needed: I have a Form with several TextField's and a
MultiFileUploadField. If you select some files to upload and enter some
text in the TextFields - after the submit everything is fine.
Now if in case some TextField fire a validation error and the page is
rendered again, you have to select the files to upload one more time. Is
there any possibility to keep the state as long as validation errors occur?
Btw same problem wit FileUploadField.
Using wicket 1.5.3.
thx

No, the only workaround is probably to do the FileUpload logic during validation, and "flag" the upload field as completed somehow (or just show that files have been uploaded)

Hi,
You can add AjaxFormComponentUpdatingBehavior to all TextFields and
set some error class when they are invalid. Add onsubmit event
listener (pure JS) to the form that will check all form elements for
such class and refuse the submit (by returning false) if there is at
least one invalid text field.
