Null GUID in GetLinkUrl() return value in Transformation

I am creating a new transformation for Page (menu item). I am using the document's Teaser image field so copied the CMS.MenuItem.ImageGalleryList code to a new transformation and customized the markup. Of course I uploaded teaser images for all the pages also.

<div class="our">
        <img src="<%# GetFileUrl("MenuItemTeaserImage") %>" alt="<%# Eval("DocumentName",true) %>" />
        <div class="our_pop_cont">
		<div class="pop_up">
			<h5><%# Eval("DocumentName") %></h5>
			<a href="<%# GetDocumentUrl() %>" class="pop_up_link"></a>
		</div>
	</div>
</div>

The markup that this produces is like:

<img alt="My Page Name" src="/getattachment/00000000-0000-0000-0000-000000000000/My-Page-Name.aspx">

...which produces a 404. I went into the database and found an actual GUID set for one of the [CONTENT_MenuItem].[MenuItemTeaserImage] pages and manually swapped that in for the null GUID and the image loaded successfully!

/getattachment/C0E089A1-2B17-4490-B462-A41380E6ABC3/My-Page-Name.aspx

So, I started with "official" Kentico code. I uploaded the image and it made it into Kentico. The image is getting served correctly (when the correct URL is requested). However, <%# GetFileUrl("MenuItemTeaserImage") %> does not produce the correct URL.

Am I doing something wrong? How do I get the correct URL for the MenuItemTeaserImage?

Kentico Developer	kentico_ivanat - 7/24/2012 9:14:37 PM RE:Null GUID in GetLinkUrl() return value in Transformation Hi, before I try to reproduce this issue, could you please confirm that you have you tried simple method? <%# GetImage("imageColumnName")%> Thank you. Best regards, Ivana Tomanickova

RE:Null GUID in GetLinkUrl() return value in Transformation

I'm experiencing this same issue. Version 6.0.37.

<%# GetImage("MenuItemTeaserImage") %> produces no result.
<%# Eval("MenuItemTeaserImage") %> produces no result.

<%# GetFileUrl("MenuItemTeaserImage") %>  produces /getattachment/00000000-0000-0000-0000-000000000000/filename.aspx

RE:Null GUID in GetLinkUrl() return value in Transformation

Hello,

If <%# Eval("MenuItemTeaserImage") %> or even
<%# Eval("MenuItemTeaserImage").ToString() %>

produces no result, it means that either the value is not defined (is null/empty), or the listing web part loads multiple classnames (document types) and the general View_CMS_Tree_Joined is used instead of the Page(MenuItem) specific - View_CONTENT_MenuItem_Joined. The general view doesn't contain the MenuItemTeaserImage field, so the result of the methods will be empty or invalid.

Could this be the cause in your setups?

If yes, the solution would be either to use just Page(MenuItem) or write a custom JOIN query and use it in the Custom query repeater (datalist).

Regards,
Zdenek

RE:Null GUID in GetLinkUrl() return value in Transformation

is there already any solution?

i have the same issue using document uploader (field type) and GetDocumentUrl/GetFileUrl in the transformation (v6.0.4297).

With File Uploader (field type) i get the right GUID BUT the file does not open correctly (just white background...)

for example: www.mydomain.com/getattachment/b4eed642-838f-4f3b-b1a0-fdf5ff34d158/my-file.aspx (nothing happens)....

Thx for your help!

best regards,

alex


Kentico Support	kentico_jurajo - 11/14/2012 5:05:28 AM RE:Null GUID in GetLinkUrl() return value in Transformation Hi, What is the exact field type - is it a document selector, file upload, direct uploader? Best regards, Juraj Ondrus


Member	alexander.moeslinger-timewarp - 11/14/2012 5:09:29 AM RE:Null GUID in GetLinkUrl() return value in Transformation as i wrote: document selector does not get any GUiD (0000-0000....) and file upload gets the guid but does not open any file (see my last post) thx regards

RE:Null GUID in GetLinkUrl() return value in Transformation

Hi,

I was confused by your last post since there is no document uploader field. The document selector selects documents, not files and it is not storing the GUID of the file.

What function are you using for the file upload field? It is not clear from your post what exactly and how are you using.

RE:Null GUID in GetLinkUrl() return value in Transformation

sorry, i meant document attachment. I tried direct uploader/upload file and Document attachments control

anyway, i just want to offer a download link on my website and have a transformation like this:

<a href="<%# GetFileUrl("MyFile") %>" target="_blank"> Download <%# Eval("DocumentName") %> (pdf, ca. 700 KB)</a>

But all i get is a link like that:

www.mydomain.com/getattachment/b4eed642-838f-4f3b-b1a0-fdf5ff34d158/my-file.aspx (nothing happens)

and this does not work?!

any suggestions?

is there also a possibility to get the file size?

thx

RE:Null GUID in GetLinkUrl() return value in Transformation

Hi,

My field is attribute type "File", form control "Upload file" and I am using exactly the same transformation to download/open e.g. the PDF file. Have you tried different browser or PDF file? This seems to me more like browser issue when opening/downloading the PDF or, it has happened that the PDF file was generated in some non-standard way with some odd header, and the browser is unable to open it.

You can test the transformation e.g. by uploading some image or text file.

Best regards,
Juraj Ondrus


Member	alexander.moeslinger-timewarp - 11/14/2012 6:10:11 AM RE:Null GUID in GetLinkUrl() return value in Transformation i will test it and post my results...thank you for the quick answers! regards


Member	alexander.moeslinger-timewarp - 11/14/2012 6:36:51 AM RE:Null GUID in GetLinkUrl() return value in Transformation now it works: images: both with direct uploader and file upload... pdf: i thought it does not work with pdf's BUT it seems to be a Firefox problem (as you suggested)...pdf-files work in Safari... thx for your help! fyi: firefox 16.0.2 best regards
