XmlList(skipWhenEmpty=true) or @SkipWhenEmpty() does not work

[martinpfeiferdev]

Hello,

I am trying to deserializer an arraycollection, however this attribute is optional, but the following error occurs: "Warning: JMS \ Serializer \ XmlDeserializationVisitor :: visitProperty (): Node no longer exists"

namespace Presentation\DataTransferObject;

use Doctrine\Common\Collections\ArrayCollection;
use JMS\Serializer\Annotation as A;
use Presentation\DataTransferObject\ListTest;

/**
 * @A\XmlRoot("Test")
 */
class Test
{
   /**
     * @var ListTest
     * @A\Type("ArrayCollection<Presentation\DataTransferObject\ListTest>")
     * @A\SkipWhenEmpty()
     * @A\XmlList(skipWhenEmpty=true,entry = "Presentation\DataTransferObject\ListTest")
     */
    private $ListTest;
}

Is there any way to when it is empty, it does not deserialize?

[goetas]

are you using a custom error handler? which serializer version are you using?

[martinpfeiferdev]

@goetas "jms/serializer-bundle": "^2.2"

[martinpfeiferdev]

@goetas I am not using an error handler

[goetas]

what about the serializer library?

[martinpfeiferdev]

@goetas I have not manipulated anything, I am using a jms library natively

[goetas]

@A\XmlList(skipWhenEmpty=true,entry = "Presentation\DataTransferObject\ListTest")

"entry" is not a valid name, can not contain \

[goetas]

can you also share your input xml?

[martinpfeiferdev]

@goetas look my xml send

@goetas my class php...

use Doctrine\Common\Collections\ArrayCollection;
use JMS\Serializer\Annotation as A;

I'm going to send the Signature class, it can only be deserialized if using XmlList.

[martinpfeiferdev]

@goetas Is there a better way to show the code, or can it be right here?

[martinpfeiferdev]

@goetas Another point is that Signature, I can only deserialize if I remove the inline.

[goetas]

to higlight the code you can use

```php for php 

```xml for xml
```js for javascript
... and so on

more info on https://help.github.com/articles/creating-and-highlighting-code-blocks/

[martinpfeiferdev]

@goetas Is there any way to deserialize an XmlList, if it is null?

[goetas]

• for XML, recommended specifying@SerializedName
• for XML arrays recommended specifying for @XmlList the namespace property
• entry="child::*" is not valid, please put the node name

[martinpfeiferdev]

@goetas I think I was doing it the wrong way, excuse me.

The solution I managed to deserialize the Signature was like this:

• @A \ XmlElement (cdata = false, namespace = "http://www.w3.org/2000/09/xmldsig#")
• @A \ SerializedName ("Signature")

[martinpfeiferdev]

@goetas Many thanks for your proactivity.
