The htmlContent tag seems to be not working in
1.2beta2.js. The problem looks like that the
AjaxJspTag.HtmlContent execute: function(e) function
does not properly call the preFunction.
The "this.options.preFunction();" fails and it should
be eval(this.options.preFunction) where the
preFunction is specified as "exampleFunction()".
In this way it was working with Firefox and IE.
