in my MultiForm Step i need fields dependend on the previous step.

Let's assume we have 2 DataObject classes:
1. Category (has_many Article)
2. Article (has_one Category)

Step1 shows checkboxes of categories.
Step 2 should bring up a checkboxfieldset of all Articles having the CategoryID selected in the first step.

I thought i can access the form data inside the method getFields() in Step2

function getFields() {
      $data = $this->loadData();

but the debug output is an empty array.

(I also checked the database: all selected CategoryIDs are save correctly. When using the previous button of MultiForm the checkboxes of the first step are also populated correctly)

Any ideas ?

I created a workaround:

function getFields() {

      $step = DataObject::get_one(
         "SessionID ={$this->Session()->ID} AND ClassName='ProposalTemplateForm_Step1'"
      if($step) {
         $data = $step->loadData();
