Problem binding

Hello,

I got a visual problem when I run my WD applications as well as the Webdynpro examples :

For example, I don't see the text value of a label but the name of the variable (i.e. "view.Form.HeaderText.text" instead of "Title of my app").

I don't understand where is the problem origin.

Concerning WD examples, I build exactly what I extract from the zip, I create the archive and deploy It, the problem appears : All texts displayed show the name of the variable instead of their (static) values.

The same thing happens with my messages coming from the Message pool.

Thanks to help me...
