I know how to check out . So are you saying that the download issue has been fixed on the code that is available on SVN?

Yes it's so easy to solve, take a look at index.html and Util.java file looking for :
Code: Select all
<div style="display:none;visibility:hidden;">
			<iframe src="" id="__download" style="width:0;height:0;border:0"></iframe>
		</div>
And then must replace Util.DownloadFile with
Code: Select all
/**
	 * Download file
	 * 
	 * @param path
	 * @param params
	 */
	public static void downloadFile(String path, String params) {

		if (!params.equals("") && !params.endsWith("&")) {
			params += "&";
		}
		final Element downloadIframe = RootPanel.get("__download").getElement(); 
		String url = Config.OKMDownloadServlet + "?" + params + "id=" + URL.encodeComponent(path);
		DOM.setElementAttribute(downloadIframe, "src", url); 
	}

Hi,

1. If I do a right click on a file, and select download, the browser spins forever.

2. If I select History -> View, I can download the file.

Following is the extract from log file which I think is relevant to the download problem.

Environment: OpenKM 5 on Win Server 2003 SE R2, with wide LAN but no Internet access. Drag instal, with ws folder removed to address lack of Internet access problem.
Code: Select all

@ jllort
Were the changes you said should be made on openKM 4.1 ?
Because I didnt find this function downloadFile in 4.1.
Can you tell me how I should fix this on 4.1

Thanks
Ravi Kiran

Re: 5.0 RC1 source code

It's easy, in version 4.1 must replace Util.download file method for 5.0 implementation and adding into index.html the div

Re: 5.0 RC1 source code

 #7114  by raviskiran
 
Code: Select all
	/**
	 * Download document
	 */
	public void downloadDocument(boolean checkout) {
		Log.debug("downloadDocument()");
		if (isDocumentSelected()) {
			Log.debug("jump to download");
			Main.get().redirect = true;
			Window.open(Config.OKMDownloadServlet + (checkout?"?checkout&":"?") + "id=" + URL.encodeComponent(getDocument().getPath()), "_self", "");
			Main.get().redirect = false;
		}
		Log.debug("downloadDocument: void");
	}
I found this in ExtendedScrollTable.java, is this the function I should change?

Re: 5.0 RC1 source code

 #7123  by jllort
 
In 4.1 probably downloading is not concentrate in Util.java

Make a search of all Config.OKMDownloadServlet ( where is referenced ). In all of that places must doing the change.
