The %3a and %2f are URL encodings of the : and / characters, and are the correct way to call this URL.  No idea why the MapTips wouldn&#39;t work properly when the appdef parameter isn&#39;t properly encoded though.<div><br>

Here is a weird one - I have MapTips with this URL launched from Studio 2010<br>
(with MGOS 2.1):<br>
<br>
<a href="http://localhost/mapguide/fusion/templates/mapguide/google_slate/index.html?APPLICATIONDEFINITION=Library%3a%2f%2fWEB_LAYOUT%2ftest.ApplicationDefinition" target="_blank">http://localhost/mapguide/fusion/templates/mapguide/google_slate/index.html?APPLICATIONDEFINITION=Library%3a%2f%2fWEB_LAYOUT%2ftest.ApplicationDefinition</a><br>

<br>
but not this one:<br>
<br>
<a href="http://localhost/mapguide/fusion/templates/mapguide/google_slate/index.html?APPLICATIONDEFINITION=Library://WEB_LAYOUT/BASEMAP_GOOGLE.ApplicationDefinition&amp;SESSION=1d31b09a-304f-102d-8000-005056ae69f8_en_7F0000010AFC0AFB0AFA&amp;LOCALE=en" target="_blank">http://localhost/mapguide/fusion/templates/mapguide/google_slate/index.html?APPLICATIONDEFINITION=Library://WEB_LAYOUT/BASEMAP_GOOGLE.ApplicationDefinition&amp;SESSION=1d31b09a-304f-102d-8000-005056ae69f8_en_7F0000010AFC0AFB0AFA&amp;LOCALE=en</a><br>

<br>
Why does studio pass a strange APPLICATIONDEFINITION rather than the one<br>
defined?  At least the Maptips work with the one launched from Studio...but<br>
how would I recreate the first one?<br><br></blockquote></div></div>
