Hello everyone,
I have a problem with switchable fields within a multifield with the
TransformerClass MultiValueSubChildrenNodePropertiesTransformer.
We need the transformer class to have the reorder possibility for all multiple
entries. Currently I am using the switchable field with some other fields in a
composite field. The composite field is then placed in the multi field (see
code below).
The creation of multiple (for my case links) fields is working well. But after
creating a module with this structure I am not able to edit it again. I always
get a ClassCastException because the MultiValueField try to cast my
SwitchableFieldDefinition into a MultiValueFieldDefinition.
Why is it possible to create a module with this configuration but not edit it
again? What's going wrong here, maybe I'm using a wrong TransformerClass?
Thanks for any help.
[code]
SwitchableFieldBuilder switchable = cfg.fields.switchable("switchable_link_")
.label(linkLabel)
.description(description)
.required(isRequired)
.options(
new
OptionBuilder().value("option1").label("option1").selected(),
new OptionBuilder().value("option2").label("option2"))
.layout(Layout.horizontal).fields(
cfg.fields.text("text1").label("").required(false),
cfg.fields.text("text2").label("").required(false));
ArrayList<AbstractFieldBuilder> someOtherFields = new
ArrayList<AbstractFieldBuilder>();
someOtherFields.add(cfg.fields.text("exampleField1").label("").value(""));
someOtherFields.add(switchable);
AbstractFieldBuilder compositeField = new CompositeFieldBuilder("link")
.fields(someOtherFields.toArray(new
AbstractFieldBuilder[someOtherFields.size()]))
.transformerClass(NoOpCompositeTransformer.class)
.layout(Layout.vertical);
cfg.fields
.multi("multiField")
.label(label)
.field(compositeField)
.transformerClass(MultiValueSubChildrenNodePropertiesTransformer.class)
.description("My description");
[/code]
This is how my JCR is looking after creating a module:
+ multiField
+ 00
+ switchable_link_
- option1 : "THEVALUE"
- switchable_link_ : "option1"
- exampleField1: "VALUE"
Where the Exception is thrown:

Caused by: java.lang.ClassCastException:
