Pollid is not found for the block of Polls

[KratorD]

Zikula 1.3.10 and Polls 3.0.1
Select the option "Latest poll" in block options for this module. Select the option "Only one vote. No recurrence" for "How soon can a user vote for each poll?"
Register a vote from the block.
Refresh page.
The poll is showed again for register a new vote for your user.

The problem is in the method "display" of the file "Polls\Block\Poll.php". When it get variables from content block:
$vars = BlockUtil::varsFromContent($blockinfo['content']);
Then use the variable "$vars['pollid']" for pollid, but this variable is "-1" (for the value for option "lastest poll").
So, when the module try to get if the user is allowed to vote
// Check if the user is allowed to vote (meaning he has already voted in this poll) $allowedtovote = (bool)ModUtil::apiFunc('Polls', 'user', 'allowedtovote', array('pollid' => $vars['pollid']));
The module response: "yes, you can vote"

it's necessary change the logic for this case, where the pollid must to be retrieve with the function
// Get the poll $item = ModUtil::apiFunc('Polls', 'user', 'get', array('pollid' => $vars['pollid']));
This function is prepare to get the last poll if $vars['pollid'] is "-1" value.

Thanks.
