Errors : Wicket RuntimeException “No get method defined for class–upload”

In a recent Wicket migration 1.3 to 1.6, my application was giving me trouble whenever used uploads an image.

Main exception

org.apache.wicket.WicketRuntimeException: No get method defined for class: class com.ptc.fusion.web.pages.admin.ManageCustomizationPage expression: upload
     at org.apache.wicket.core.util.lang.PropertyResolver.getGetAndSetter(
     at org.apache.wicket.core.util.lang.PropertyResolver.getObjectAndGetSetter(
     at org.apache.wicket.core.util.lang.PropertyResolver.getObjectAndGetSetter(
     at org.apache.wicket.core.util.lang.PropertyResolver.getValue(
     at org.apache.wicket.model.AbstractPropertyModel.getObject(
     at org.apache.wicket.Component.getDefaultModelObject(


I spent several hours on this issue, and once again, I figured it out 20 minutes after I posted to SO about it. The fix is to turn the upload field declaration into one that provides a model, like this:

fuf = new FileUploadField("DocumentUpload", new Model<FileUpload>());

EDIT: It turns out this was related to 1.3 -> 1.4 migration. Per the migration guide,

FileUploadField – now requires model

The FileUploadField now REQUIRES a model. This means that if you previously used the ID-only >constructor (i.e. new FileUploadField(“myFileField”)), you will need to change it to include >a model (i.e. new FileUploadField(“myFileField”, new Model())).


Previously constructor was like :

final FileUploadField uploadField = new FileUploadField(“upload”);


The problem got resolved just by using the new constructor mentioned below :

        IModel uploadModel = new Model<FileUpload>();

    public IModel getUploadModel() {
        return uploadModel;

    public void setUploadModel(IModel uploadModel) {
        this.uploadModel = uploadModel;
    final FileUploadField uploadField = new FileUploadField(“upload”, uploadModel);
