Javascript hyperlink in OWC spreadsheet

[Michael Loughry]

I'm working on a web application for my company, and part of it includes a
OWC spreadsheet. In the cells in one column, I want to add a hyperlink that,
when clicked, calls a javascript function. Therefore, in the Office XMl, Id
do the following:

<ss:Cell ss:HRef="javascript:RefreshDocTree(some parameters);">;
<ssata ss:Type="String">Launch Documents</ssata>
</ss:Cell>

However, when I click on it, IE complains that it is "Unable to navigate to
javascript:RefreshDocTree(some parameters);

Any ideas if what I'm trying to do is possible, and how I might do it?
