Re: [Ext] Re: file upload doesn't set file value

1) I have the following dependencies

<dependency>
    <groupId>org.apache.tapestry</groupId>
    <artifactId>tapestry-upload</artifactId>
    <version5.4.3version>
</dependency>

Tried with and without the following two. Didn’t make any difference:

<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.2</version>
</dependency>

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.4</version>
</dependency>

2) Since I have the validate="required" in the .tml, it always display error message “You must provide a value for File”. It didn’t even get to the onSuccess(). If I remove the validate="required", it got to the onSuccess. But the file is null. So, yes, it throws NPE when trying file.getFileName().

3) I’m using it with SpringBoot. Not sure if that will make any difference.

Thanks,
Dongmei

I am using it and it is working ok:

1. Did you add depedency to tapestry-fileupload module ?.
2. Does it throws a Null Pointer Exception or simply you do not see then file created ?
3. The path in "copied" File instance must exist, the method write will not create it.

I recently begun to use it without trouble.

Hi,

I know this is an old post. I’m trying to migrate our app from 5.3.8 to 5.4.3, and finding the file upload is no longer working. I’m not using t:zone at all. But the file value is always null. I see the JumpStart site (http://jumpstart.doublenegative.com.au/jumpstart/[jumpstart.doublenegative.com.au]) have the “File Upload” example disabled. Anyone has a working example. Could you please share?

<t:form>
    <t:errors/>
    <input t:type="upload" t:id="file" t:value="file" validate="required"/> <br/>
    <input type="submit" value="Upload"/>
</t:form>


    @Persist
    @Property
    private UploadedFile file;

    public Object onSuccess() {
        System.out.println(file.getFileName());
        File copied = new File("/my/file/location/" + file.getFileName());
        file.write(copied);

        return this;
    }

Thanks,
Dongmei
