what does this fluid error means? No unique path segment could be found after 100 iterations - fluid

Question

I get this error on an order review page:
Exception while rendering
checkout<TYPO3.Neos:Page>/
body<TYPO3.TypoScript:Template>/
content/
main<TYPO3.Neos:PrimaryContent>/
default<TYPO3.TypoScript:Matcher>/
element<TYPO3.Neos:ContentCollection>/
itemRenderer<TYPO3.Neos:ContentCase>/
default<TYPO3.TypoScript:Matcher>/
element<SeeThroughWeb.Shop:ShopOrderReview>:
No unique path segment could be found after 100 iterations. (201409261654538b6e30)
Any idea why or what it means? BTW, I use the same template on another site and get no such error there. I am using Flow 2.1 and Neos .99 .
Thanks
The method declaration is:
/**
* A new form to fill shipping address
*
* #param \SeeThroughWeb\Shop\Domain\Model\Address $address List of address
* #param integer $changeAddress
* #return void
*/
public function shippingAddressAction(\SeeThroughWeb\Shop\Domain\Model\Address $address = NULL, $changeAddress = 0) {
and here is a fuller listing of the template section referenced in my comment below:
<f:for each="{addresses}" as="address">
<li>
<f:link.action action="shippingAddress" arguments="{address: address}">{address.title}</f:link.action>
</li>
</f:for>
A similar error ont he same page, seems to be related tot he address variable somehow:

and the exception log looks like this:

The declaration of editOrderAddressForAdmin looks like this:
/**
* Edit order address for admin
*
* #param \SeeThroughWeb\Shop\Domain\Model\Address $address
* #param integer $shipping
* #Flow\IgnoreValidation("$address")
* #return void
*/
public function editOrderAddressForAdminAction(\SeeThroughWeb\Shop\Domain\Model\Address $address , $shipping = 0) {
$this->view->assign('address', $address);
$this->view->assign('shipping', $shipping);
$countryAndStates = $this->taxZoneService->getCountryAndStates();
$this->view->assign('countries', $countryAndStates['country']);
$this->view->assign('states', $countryAndStates['state']);
}
In the template I can avoid the exception by commenting out the following line:
<f:link.action action="editOrderAddressForAdmin" controller="OrderManagement" arguments="{address: order.shippingAddress, shipping: 1}" >
<div class="editOrderDetails">(edit)</div>
</f:link.action>
So again its a link that involves an address object.

Answer 1

Problem lies in address argument..
I guess you may have wrong type defined for address argument for shippingAddressAction().. sth like #param \My\Package\..\wrongType $address.
Second thing might be related to Routes.yaml - for example error in routeParts.. not unique property used in uriPattern or again wrong objectType there..
You can also add #Flow\IgnoreValidation("$address") in shippingAddressAction() - and check what happens, look at the bottom of http://docs.typo3.org/flow/TYPO3FlowDocumentation/TheDefinitiveGuide/PartII/Validation.html
