[mapguide-users] RE: Hyperlink in tool tip

[GIS4U]

Hi Darwin,
I no longer have access to that code but it really comes down to knowing
exactly what is coming through in the URL. NULL vs "" vs "Value" and then
catching that case for empty URLs. You then have to follow the URL through
the functions (javascript alerts help) and put the appropriate IF THEN ELSE
in there.

This may also involve working with the SQL. For example, putting: 'No
Hyperlinks available for this record' shows the user there is no point
clicking and may resolve your problem.

Hope that helps,
Jonathon
