Other Languages - Enterprise portal and Dynamics AX 2009: Problems doing an edit form

Hi all, I'm trying to do an edit form in Enterprise portal with Dynamics AX 2009.
First of all, I have a web page with an web part with a grid and a datasource, and in this web page, I have a connected axapta toobar with the previous web part, through the AxContextList .
Also, I have a web menu with an element that is an url web menu item to my edit web page, and this web menu has like parameters "mode=1".
This edit web page, has an axgroup with the columns for editing.
Ok, the problem is that when I click in one row of my grid, and I click in my web menu item of my axapta toolbar, my edit web page appear, but the current item for editing isn't the item that I have selected, and this item is always the first item.

Thanks in advance for your help, because for me this problem is difficult to explain.

greetings.
