Hi, in my view I have a DrowDownList with TreeView inside, this worked fine before upgrade versione (15.3.0.33) of syncfusion but now  I have this error

This is a part of code 

 <div class="form-group">

        <div class="col-md-2">

           e => e.Create("dropDownCategoriaOnCreate")).ReadOnly(disableControls)
 
            <div id="categorie">
