Select element not serializable?

[Gabriel Martins]

I got a strange error when I changed the text element in form of UploadStep.java for a select.

Here's the code:

Text description = upload.addItem().addText("description");

description.setLabel(T_description);

description.setHelp(T_description_help);

for:

Select description = upload.addItem().addSelect("description");

description.setLabel(T_description);

upload.addItem(T_description_help);

description.addOption("article", "Article");

description.addOption("book", "Book");

description.addOption("presentation", "Presentation");

It's works fine, but for some reason I get stuck in upload step while doing a submission.

Tomcat show this error:

Cannot serialize session attribute FOM JavaScript GLOBAL SCOPE/resource://aspects/Submission/sitemap.xmap for session 046207AB32F258732CBDC5650510C39A
