RE: JavaScript not working correctly when both portlets are in vi
ewmode...
Or else you could do as suggested by the JSR168 specification and use the
RenderResponse.encodeNamespace(String) method to generate unique (to the
page) function names for each of the Javascript functions called by each
portlet.
>From the Javadoc:
"Maps the given string value into this portlet namespace and therefore
ensures the uniqueness of the string value in the whole portal page. This
method should be applied to every variable or name used in the output
stream. For example a function name in javascript. "

No, it doesn't. I'm looking at the Portlet API (V1.0) right now,
and there is no such method.
To make sure I'm right, I also searched the specification for mention
of this method.
Instead, look at the documentation for RenderResponse.getNamspace, both
in the API documentation and in the specification. Here's an excerpt
from the javadoc:
"The value returned by this method should be prefixed or appended to
elements, such as JavaScript variables or function names, to ensure they
are unique in the context of the portal page."

RenderResponse inherits this method from PorletResponse.

Thank you Nick. But I can't find the method you mention in JSR 168 Spec 1.0.
