Re: Is there any way to get an error message when uploading a file that exceeds the size limit?
>Hum... if you can explain more I would appreciate it... because maybe this can be improved in Wicket itself. If use FileUploadField#setRequired(true), FormComponent #validateRequired -> #checkRequired will be executed. But FileUploadField#getInput() returns null, so validation result in an error. Therefore, It seems that the Behavior's(FilesSelectedBehavior) event that FileUploadField has is not fired. 2022年6月10日(金) 21:19 Ernesto Reinaldo Barreiro : > Hi, > > On Fri, Jun 10, 2022 at 2:31 PM Ryo Tsunoda > wrote: > > > Thanks for the reply. > > > > I have tried it and I can display the error without changing the request > > limit. > > Thank you. > > > > Yes.

This is just a kind of preprocessing. When the file (files) is (are) selected the info is collected via JavaScript and is sent to the server. Thus you can decide what to do before uploading: e.g an upload button might only be enabled if file (files) match your expectations regarding type, syze and so on. > It does not seem to work well when used with FileUploadField#setRequired. > I will change the implementation of the required validation and then use > that. > Hum... if you can explain more I would appreciate it... because maybe this can be improved in Wicket itself. > > 2022年6月10日(金) 16:21 Ernesto Reinaldo Barreiro : > > > See > > > > > > > https://javadoc.io/doc/org.apache.wicket/wicket-core/9.4.0/org/apache/wicket/markup/html/form/upload/FilesSelectedBehavior.html > > > > This behavior can be used to get an AJAX round trip to the server when > the > > user selects a file (or files).

Re: Is there any way to get an error message when uploading a file that exceeds the size limit?
Thanks for the reply. I have tried it and I can display the error without changing the request limit. Thank you. It does not seem to work well when used with FileUploadField#setRequired. I will change the implementation of the required validation and then use that. 2022年6月10日(金) 16:21 Ernesto Reinaldo Barreiro : > See > > > https://javadoc.io/doc/org.apache.wicket/wicket-core/9.4.0/org/apache/wicket/markup/html/form/upload/FilesSelectedBehavior.html > > This behavior can be used to get an AJAX round trip to the server when the > user selects a file (or files).

Re: Is there any way to get an error message when uploading a file that exceeds the size limit?
See https://javadoc.io/doc/org.apache.wicket/wicket-core/9.4.0/org/apache/wicket/markup/html/form/upload/FilesSelectedBehavior.html This behavior can be used to get an AJAX round trip to the server when the user selects a file (or files). Then you can use that information to let the user know the selected file is bigger than it should (and possibly disable the upload "button").
