RE: net.sf.saxon.trans.DynamicError

Here is the code I am using to create a pagination. I don't get this
error all the time it happens once in a while.

and

I think you probably will want to post a stripped-down version of
some
code that exhibits this problem.

I didn't look further than the error above. I don't know any other
way
of throwing this error except writing a circular variable definition.
The simplest would be:

  <xsl:variable name="selectedRowCount" select="$selectedRowCount"/>

Equally bad is:

  <xsl:variable name="someOtherVariable" select="$selectedRowCount"/>
  <xsl:variable name="selectedRowCount" select="$someOtherVariable"/>

Note that even if you've something as ghastly as the first example in
a
stylesheet, saxon won't throw an error unless you try to evaluate an
expression that references selectedRowCount. This depends on the rest
of
the stylesheet and the input. (There may well be exceptions; I
wouldn't
know.)

Hope that helps.
