Thanks for the response Chuck,
This is the rendered HTML
<form name="f_0_5_11_1" method="post" class="form-inline" id="form-login"
action="/cgi-bin/WebObjects/aplicacionbase.woa/-55550/wo/N9l418Wx25eGL6kgGhK3Aw/0.0.5.11.1">

I am assigning the context.elementID() to the button's name.
When I click on the button the context.elementID() is 0.5.11.1.3.9, which is
correct.
But the context.senderID() is 0.5.11.1
This is the URL with the context's ID
http://localhost/cgi-bin/WebObjects/aplicacionbase.woa/-55550/wo/w46py2RT6cjHT2iRyyRib0/0.0.5.11.1
I am not sure Who is the owner of the 0.5.11.1 ID.
