Came across a weird ‘feature’ last week to do with a table field report causing a java script error on the page with the error message ‘Children.0.Style is null or is not an object’.
This appears to occur if you have more than the left most column set to fixedheader = true.
If you set ALL the columns to fixedheader = true you get the following deployment error
Error 1 [rsInvalidFixedTableColumnHeaderSpacing] The table ‘XXX’ includes improperly placed columns with FixedHeader set to true. These columns must be side-by-side, must start with either the left-most or right-most table column, and cannot be applied to all columns on the table.
The original Java error was occurring when the first and second columns were set to true and not the third, which according to the error description should have worked, but obviously doesn’t.
… These columns must be side-by-side, must start with either the left-most or right-most table column…
