Summary

0006289: sessions are not saved to persistent storage for jsp pages with c:import tag

Description

(rep by alpor9)

Problem appears if there is <c:import> tag in the target page.

If page contains any such import, any session manipulations on that page will not be saved to persistent storage.

Because import request clears _isModified flag in SessionImpl#load() (see line 725 in SessionImpl.java for 4.0.48).

And then, the subsequent SessionImpl#save() method (after the main page request) sees nothing to save. And 4.0.62 has the same logic there.

Additional Information

Steps to reproduce:
1. view.jsp => see that attribute is null
2. save.jsp
3. view.jsp => see that attribute is "bar"
4. remove.jsp
5. view.jsp => see that attribute is null
6. restart resin
7. view.jsp => see that attribute is "bar"
8. remove_no_import.jsp
9. view.jsp => see that attribute is null
10 restart resin
11. view.jsp => see that attribute is null

save.jsp
