WebContent ClassCastException

Hi!I try load an assetList. This list contains webcontent that has an options field. The assetList give error when loading list:
E/LiferayScreens: Error loading list
    java.lang.ClassCastException: java.lang.String cannot be cast to java.util.ArrayList

if (ddmStructure.getFieldCount() &gt; 0) {
					html = (String) ddmStructure.getField(0).getCurrentValue();
				}

In WebContent class while parsing dynamic-elements StringWithOptionsField's getCurrentValue() method is returning ArrayList<Option> not a String.
	@Override
	public ArrayList<option> getCurrentValue() {
		ArrayList</option><option> options = super.getCurrentValue();

		if (options == null) {
			options = new ArrayList&lt;&gt;();
		}

		return options;
	}</option>


What can I do?

It's definitely an error... I don't know why that code is there, it doesn't make any sense. I can release a new version filling the html field when it makes sense... but what do you want to render? a custom view with the fields or the raw html (you need a template for that)

Hi! Sorry, I was on holiday. We want to render a text field with fixed values. I see on gitHub you fixed that issue.
