Form submit sends GET request, if Wicket-generated URL contains jsessionId

[Igor Khvostenkov]

Hi *,

I faced with the problem. When Wicket-generated URL contains jsessionId, form 
submitted with GET request, and not POST. If I remove jsessionId from URL, then 
normal POST request is done. I have no idea where this GET is coming from. I 
ovverode getMethod() to always return POST and issue still exist. Any ideas 
where I can look to figure out why GET request is done?

Generated HTML:

<pre>

<form role="form" id="accessForm5" 
wicketpath="pageBorder_pageBorder__body_mainBorder_mainBorder__body_contentBorder_contentBorder__body_content_accessForm"
 method="post"
