Dojox Uploader sends empty file using IFrame plugin

[ldavis]

When using the IFrame plugin on dojox.Uploader under IE, every upload sends an additional zero byte unnamed file. It does send the correct file as well, so you can filter out this bad file on the server.

However, it is more of a problem when you use FileList?, as the zero byte unnamed file is the one the appears in the list, not the desired file you want to upload, so it is misleading to the user.

Just ran into this problem too... hoping to find a way to fix it... so far no luck in debugging it though :(

In version 1.8.x

Dirty fix for 1.8 (not for the new AMD version of the uploader) [sorry this is not a patch file, but generating the patch was being a PITA today] -- it adds a dependecy on dojo/query and dojo/dom-construct

in IFrame.js uploadIFrame function.... add the query() below the if/else check near the top -- note: this could use better error checking if the form is used for other input types than just files --- hence the "dirty" aspect of the fix... working on a cleaner patch for trunk version

		}else{
			form = this.form;
		}
		
		query("input", form).forEach(function(node){
			console.log("checking for empty fileNode: ", node.name, node.value);
			if (node && !node.value) {
				console.log("destroying: ", node.name);
				construct.destroy(node);
			}
		});
