[TYPO3-mvc] Another shot : Problems with persisting updated Properties of related models via Frontend Fluid Form

[Frank Gerards]

Hi,

 

I render a frontend edit-Form to edit a model "offer", which has some
"items" attached to it.

I loop over each item to get its properties as form-fields.

So the "name" of a item property form input field is:

 

1st item:

tx_myExt_myplugin[offer][item][<someSortOfHash>][myProp] 

 

2nd item:

tx_myExt_myplugin[offer][item][<someSortOdifferentfHash>][myProp] 

 

I see that each object in the lazyObjectStorage is of type Item and has
a unique identifier.

When submitting this form, I get :

 

An error saying "array cannot be converted to plain value" using the old
property mapper AND/OR

"Exception while property mapping at property path
"item.<someSortOfHash>": Creation of objects not allowed. To enable
this, you need to set the PropertyMappingConfiguration Value
"CONFIGURATION_CREATION_ALLOWED" to TRUE.

 

I digged into the extbase core code and found, that this exception is
only thrown, if the incoming Request argument for

The typeConverter is an Array AND has no identity set.

 

So my question: What am I missing in my form ? I do all the form fields
using f:form.textfield , for the items inside an f:for ViewHelper.

 

I hope someone can raise my PropertyMapper horizon a bit,

Thx in advance.
