VariableInsertion with snippets [message #130005]

Hello,

I'm about to write a plug-in that provide some "code snippets" as a new
category in the snippet view. I'm using Rational Webdeveloper 6. In my
plug-in I'm using the extension point
"com.ibm.sse.snippets.SnippetContributions" which has moved to
"org.eclipse.wst.common.snippets.SnippetContributions".

When I start RAD my category appears in the snippet view and also my
snippet is there. As long as I don't use any variables the insertion of
the snippet works. When I use the <variable>-tags to specify which
variables the user is to be asked about, the dialog opens in which the
user is supposed to edit these variables. As soon as one of the lines
which contains the variables is selected an exception is thrown. Maybe the
declaration of the variable-tag is wrong?

I've been trying to fix this now for hours and I'm getting desperated ^^

What follows is the exception that is thrown and after that the content of
my plugin.xml

Questions like this should be directed at IBM support, but it looks
like you have a malformed plugin.xml file. I wasn't able to
reproduce the problem you're seeing after correcting it.
