Working on that "Survey" example.

If the user enters some special characters as a title string,
they may have to be escaped before I can write it into my HTML file.

Is there some helper to do this in the generator?

Tried your hint with some example from the web:

import org.apache.commons.lang.StringEscapeUtils;
String results = StringEscapeUtils.escapeHtml("gjhkj>-");

when I try to enter in my SurveyGenerator.extend:

import org.apache.commons.lang.StringEscapeUtils;

I get an error that this can not be resolved to a type.
and therefore the following code fails as well:

def test1 () {
val escaped = StringEscapeUtils.escapeHtml("abc");
}

Is there something I overlooked?
TIA, Uli
