Kamil created WICKET-6468:
-----------------------------
Summary: Caption Label should be hidden in MultiFileUploadField
when model is empty
Key: WICKET-6468
URL: https://issues.apache.org/jira/browse/WICKET-6468
Project: Wicket
Issue Type: Improvement
Reporter: Kamil
Attachments: showcase-fileUpload.zip
When you run the wicket-quickstart app, you'll see a page with
MultiFileUploadField.
Although no files are selected, "Files:" caption is being visible.
I think that if "IModel<? extends Collection<FileUpload>> model" is empty, then
"caption" label (Line 193) should not be visible.
I'd add something like:
{code}
Label caption = new Label("caption", new CaptionModel()) {
@Override
protected void onConfigure() {
super.onConfigure();
setVisible(model.map(Collection::isEmpty).getObject());
}
};
{code}
