Method Detail

isFormattedAsELExpression

public static boolean isFormattedAsELExpression(String expression)

Returns true if given expression contains some special characters, in which case no transformation of the widget field definition will be done to make it compliant with DocumentModelResolver lookups when handling document fields. Special characters are:

• ".": this makes it possible to resolve subelements, for instance "myfield.mysubfield".
• "[": this makes it possible to include map or array sub elements, for instance "contextData['request/comment']" to fill a document model context map.

Throws:

NullPointerException - if expression is null
