Hello, I'm trying to bind a Map entry to h:inputText. The code below successfully extracts the value for the key when the page is loaded, but when I submit it, the page reloads with an error alongside the field: model validation failed:String index out of range: -1 | <h:form id="dataEntryForm"> | ... | <h:inputText id="asdf" required="true" value="#{biomarkers['waist']}" /> | ... | </h:form> | | ... | @Out | Map<String, String> biomarkers = new HashMap<String, String>(); | ... | // method code that preps the Map prior to being used | biomarkers.put("waist", "33.3"); | ... | Thanks to anyone who can offer some assistance!
