[opencms-dev] Dynamic ComboBox Question (URGENT)

[Jonathan Woods]

Good point.

There needn't be a problem with XML document validation, because the
OpenCms-flavoured schema would probably not be valdating down to that level.
As far as rendering old data is concerned, you'd just have to write a more
intelligent extension of CmsComboWidget: when called upon to render itself
with an obsolete value as the current value, it would have to render the
obsolete entry too, but have some means - Javascript, I guess - of
preventing reselection annd allowing only current entries to be chosen.

This is a problem which must have been solved many times in the past - I
know I've ended up writing several HTML form toolkits over the years! - so I
wonder if for OpenCms 7 some more extensible and de facto standard toolkit
couldn't be used.  Perhaps this will all be part of the AJAX work which
Alkacon have said they'll do.

Hello,

This sounds very interesting, I just would to ask if there wont be some
problem with this "dynamic content listbox" in saved XML document. What
would happen, if the content of listbox will be changed later and I will try
to edit previously created document saved with some different count or
parameters names of that combo box. Thx for your answer.
