I have a visualforce page with a custom controller to display a custom table of cases. I want to add a link for any given case listed for a user to accept the case. Can I use the $Action.Case.Accept function to achieve this? 

When I load the page I get the following error: 
"The value of the "ids" parameter contains a character that is not allowed or the value exceeds the maximum allowed length. Remove the character from the parameter value or reduce the value length and resubmit. If the error still persists, report it to our Customer Support team. Provide the URL of the page you were requesting as well as any other related information."



Page:

<apex:page controller="casePollList" >
	<div style="width:70%;">
	<div style = "width= 100%; text-align: center; font-size: 20px;">
