Hi Andreas,
By looking in the error stack trace below, you must see in your
DBTextSnippet.java code line 44.
I got your source but i'm not sure it is really line 44 where's the error
occur(maybe you have breakline somewhere)
well, my guess is this below code,
if(snippetGetterMethod == null)
snippetGetterMethod = visitClass.getMethod(snippetGetter,
parameterTypes);
/*this is line 44*/String txt =
(String)snippetGetterMethod.invoke(visitObject, arguments);
this code tells that if snippetGetterMethod value is null it should get the
value from visitClass.getMethod(snippetGetter, parameterTypes);
i suggest you have to re-check snippetGetterMethod value after being set by
visitClass.getMethod(snippetGetter, parameterTypes);
it is already have the value or it is still null.
if(snippetGetterMethod == null)
snippetGetterMethod = visitClass.getMethod(snippetGetter,
parameterTypes);
if(snippetGetterMethod == null) logger.debug("still null there...");
String txt = (String)snippetGetterMethod.invoke(visitObject,
arguments);
cheers,
Gunna

I can't get this solved. I had added some extra debugging output and
I waited for 48 hours and contacted the server again. As soon as my
dynamic text component tries to ask the page's visit class for a
specific
text (the database handling is not done inside the text component, I
get the following error:
Component exception : null
