Howard M. Lewis Ship commented on TAPESTRY-2095:
------------------------------------------------

Found a bug where a path without a slash will not be prefixed with "./" even if 
it contains a colon.

> createActionLink fails to return URL usable in images when no parameter is 
> given

>             Project: Tapestry
>          Issue Type: Bug
>          Components: Core Components
>    Affects Versions: 5.0.8, 5.0.9
>         Environment: MacOS X, Jetty, Eclipse
>            Reporter: Moritz Gmelin

> I have a dynamically created image from a service on my page.
> The method to create the link is as follows
>        public Link getBPURL(){
>               return getResources().createActionLink("BPGraph", false, new 
> Object[] { });
>       }
>               
> This is how the .tml part looks
>       <img id="bpimg" class="dia_img" src="${BPURL}" width="800" 
> height="400"/>
> And this is the resulting html code
>       <img class="dia_img" height="400" id="bpimg" src="databp:BPGraph" 
> width="800">
> The browser refuses to render an image since it considers the URL 
> "databp:BPGraph" as invalid (which I can somehow understand).
> If I add a dummy parameter in the method that creates the Link
>       public Link getBPURL(){
>               return getResources().createActionLink("BPGraph", false, new 
> Object[] { 1 });
>       }
> the rendered html looks like this
>       <img class="dia_img" height="400" id="bpimg" src="./databp:BPGraph/1" 
> width="800">
> This is OK for my browser. But I would consider it a but in the way tapestry 
> (since 5.0.8) shortens the URLs.
