Answer 1

Actually it is looking for a property with name authLevel[0] which is not defined in the class from the statement "Invalid property 'authLevel[0]' of bean class". Also the size of property is not defined so make sure before fetching you are setting the data in the property.

Answer 2

I found soultion please see below for code
<form:radiobuttons path="authChainCodes[${seq1.index}].levelId" items="${authLevelFactor.value}" itemValue="levelId" itemLabel="levelDesc" element="li"
disabled="${!authLevelFactor.value[seq1.index].levelActive}"/>
