[opencms-dev] problem w/ full textarea in (News-)module

[Tobias Gaekle]

hi list,

we're using OpenCMS to build our new site and therefore wrote some
modules for it. they're structured like the news-Module that can be
downloaded from the opencms.org. now the problem:

when a lot of text (> 1000 chars) is entered in a textarea and then
posted to be written to the database, the following error occurs:

[CmsException]: 18 Unknown XML datablock. Detailed Error: Unknown
Datablock selectboxWithParam requested..

i suspect something like A_CmsBackoffice trying to access the template
which cannot be accessed yet because the post is not finished. 

the same error occurs with the downloaded NewsModule! (lots of text
entered in textarea labeled 'Inhalt')

our project is due this week. any hints, explanations or suggestions
esp. from the developers would be highly appreciated.
