Comment 4 Tomas Pavek 2002-03-04 10:58:24 UTC 
This is a serialization issue between JDK 1.3 and 1.4.
Comment 5 Tomas Pavek 2002-03-04 17:00:27 UTC 
This can be solved only by moving to XML storing/reading of the table 
model. I'm going to implement issue 19069. Serialized data from 
previous version forms will be read, but then stored in XML, so it 
won't be readable for older IDEs... But I don't see another solution.
Comment 6 Marian Mirilovic 2002-03-04 17:07:55 UTC 
Ok, I agree with this one, your described solution is the best what we
can do now.
Comment 7 Tomas Pavek 2002-03-04 17:51:25 UTC 
Fixed.
Comment 8 Marian Mirilovic 2002-03-05 09:04:23 UTC 
verified in [nb_dev](20020305), now table model storing is xml-ized.

We cannot make anything else with the exception.

================================

Work Arround:
1. open form file with JTable in NetBeans (oldest than 5th March 2002)
on JDK1.3.x and save it
(table model have saved as xml - not serialized)

2. open the same file in NetBeans runned on JDK1.4

========================

Good job Tomas, thanks.
Comment 9 Patrick Keegan 2002-05-06 19:51:48 UTC 
Does this problem appear in NB 3.3.2/Orion?
Comment 10 Tomas Pavek 2002-05-15 11:15:24 UTC 
The fix was made only for 3.4 dev, so the problem appears in 3.3.3/Orion.
Comment 11 Patrick Keegan 2002-07-23 15:50:37 UTC 
removing relnote keyword

Resolved for 3.3.x or earlier, no new info since then -> closing.
