Description

There is a discrepancy between Button implementation of getForm (derived from FromComponent) and the code in org.apache.wicket.markup.html.form.Form.findSubmittingButton()
Last one assumes form can be null while org.apache.wicket.markup.html.form.FormComponent.getForm() throws an exception if it is so

This was fixed in 1.3.3 based on https://issues.apache.org/jira/browse/WICKET-1414. Please migrate the fix to 1.4 code line.
