rich:fileUpload does not work in portlets because it does not utilize javax.faces.encodedURL for the XmlHttpRequest URL ----------------------------------------------------------------------------------------------------------------------- Key: RF-12273 URL: https://issues.jboss.org/browse/RF-12273 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component, portal Affects Versions: 4.2.0.Final Reporter: Neil Griffin Assignee: Ken Finnigan Fix For: 4.2.3.CR1, 4.3.0.M2 The fileupload.js JavaScript resource has a bug such that it uses the form's "action" attribute as the XmlHttpRequest URL, rather than the "javax.faces.encodedURL" hidden field value. I think this is where the problem exists: {code} __submit: function() { var originalAction = this.form.attr("action"); var originalEncoding = this.form.attr("encoding"); var originalEnctype = this.form.attr("enctype"); try { var delimiter = originalAction.indexOf("?") == -1 ? "?" : "&"; this.form.attr("action", originalAction + delimiter + UID + "=" + this.loadableItem.uid); this.form.attr("encoding", "multipart/form-data"); this.form.attr("enctype", "multipart/form-data"); richfaces.submitForm(this.form, {"org.richfaces.ajax.component": this.id}, this.id); richfaces.Event.fire(this.element, "onfilesubmit", this.loadableItem.model); } finally { this.form.attr("action", originalAction); this.form.attr("encoding", originalEncoding); this.form.attr("enctype", originalEnctype); this.loadableItem.input.removeAttr("name"); } },{code} Until this is fixed, the component will not function in a portlet environment.
