Nested JSF Composite Components leading to a Stack Overflow exception
jsf,jstl,stack-overflow,composite-component,nesting
The problem was in the context of the #{cc} and the statefulness of the composite attribute. The #{cc} in any attribute of the nested composite references itself instead of the parent. The attribute being stateful means that the #{cc} was re-evaluated in every child which in turn ultimately references itself...

How to populate the dropdown list from sql server database using LinkedHashMap in java

How do I set this map value to null in JSTL?
You can just do: value: ${myMap[myId]} <c:set target="myMap" property="${myId}" value="" /> and then in later code you can test if it's empty with: <c:if test="${myMap[myId] is empty}"> and avoid trying to deal with "null" in JSTL. The (probably) better option is to remove it from the map entirely: <c:set var="debug"...
