[TYPO3-mvc] Cannot cast object of type"Tx_Extbase_Persistence_QueryResult" to string.

[Johannes C. Schulz - EnzephaloN IT-Solutions]

Thanks for the answer.

So it might be possible, that the "stolen" paginate-widget throws the error?

type"Tx_Extbase_Persistence_QueryResult" to string.

Hi Johannes,

The function below looks good; the problem must stem from accessing the
return value (a QueryResult) directly without iterating or using
->getFirst() - that would cause the error message.

Could this be because of something done in Fluid using that QueryResult? If
so, it should help if you either iterate the QueryResult or use
{queryResult.first} (I believe - can't remember wether the {var.first} is
the proper way of getting the first record available from Fluid...
