hello,

under birt i have created a simple report consisting of report headers and a simple table. headers only contained text whereby the table also contained only text yet. before commiting under svn the report was fine, however once commited it could not be opened anymore. it said: could not open the editor: an unexpected exception was thrown. attached please find a screenshot, error details and a log.

reproducible: always

steps to reproduce:
1. open blank report under project
2. from library insert 2 headers where 1st header is grid subject that contains 2 rows - empty text field in 1st row and empty label in 2nd row. 2nd header is also grid that contains 5 rows  where 1st, 3rd and 5th rows are empty text fields, 2nd and 4th rows are empty labels
3. fill headers text fields with text
4. insert table that contains 4 columns and round 25 rows. first column is all by hand entered text. first 2 rows are text.
5. since birt reported that report had to have some data source i had created a flat data file data set - a *.csv file that contained only text in 2 rows: "sors asset management"
"sors asset management"
and pasted this data set into 1.1 position of the table and saved the report. report was fine untill commited under svn. then it could not be opened anymore
