- Summary:
Fix 129778 in DtE side

- Bugzilla Bug (s) Resolved:
[129778]: Support rendering based on unfinished folder-based report document archive

- Description:
To fix this bug, there are two things done in DtE:

1)      DtE changes its way to store the _expression_ value. In old implementation, only moving from one row to another row, the _expression_ value would be stored. In new implementation, the _expression_ value will be stored simultaneously when it is popped up.

2)      DtE remove the use of buffer output stream, since the buffer mechanism is already provided by the RA stream.

 

New implementation is still compatible with old report document, although the feature is not supported.

- Tests Description:
Junit Test
