conditional serialization skip empty attributes

[Bruno]

Hi!

Is it possible to skip certain objects when serializing?

for example, in my VO I have several attributes that dont get
populated and i would like to omit them on the serialization, like
empty arrays or null objects.

Many thanks in advance!

Looking through the code it seems that FlexXb already does that. if
you have null properties it will not serialize them. Do you not have
the same behavior?

Hi Alex!

Thanks for your answer. the node that gets serialized is an Array. If the array does not have any children, they are not written but parent itself is (the enclosing array) following is an example:

<imageFormats> node with contents:

<field section="section1" inputType="Image" tag="image" templateName="background" displayName="Image" contentType="Text" required="true">
              <imageFormats>
                <imageFormat name="article" width="748" height="374"/>
                <imageFormat name="grid" width="198" height="148"/>
                <imageFormat name="favorite" width="148" height="75"/>
              </imageFormats>
            </field>

<imageFormats> node with no contents (shouldnt exist)

<field section="section1" inputType="TextField" tag="location" templateName="venue" displayName="Location" contentType="Text" required="true">
              <imageFormats/>
            </field>

I´m still learning the library, but couldn´t find the error.

Thanks!!

Oh, ok, I see. Yes, empty arrays are still serialized. A quick fix
would be to set that array field to null.
