Invalid HTML Characters

The Logi Server Engine may generate errors if it needs to read a string of characters as XML and that XML includes un-escaped, invalid XHTML characters.

A primary examples of this is when AJAX-style requests are used, such as data table sorting or paging (when Ajax Paging = True has been set), or use of an Action.Refresh Element that includes a data table or other data object. In these cases, the XML data may be indistinguishable from XML tags and reserved characters.

This can also happen when HTML is included in a report definition using the techniques discussed earlier.

The most common culprit in this scenario is the inclusion of unencoded "&" characters. In situations like those described above, the application will fail and produce an error message that looks like a parsing error.

Replacing the "&" character with "&"is often an easy solution.
