<c:when>

Standard JET2 Control Tags

when

Define a one of the mutually exclusive cases of a 'choose' tag. The body of this tag is processed only if the 'test' XPath expression evaluates to 'true', and no previous 'when' or 'otherwise' tag in the containing 'choose' tag has processed its body content.

If the 'test' XPath expression is does not result in a boolean value, then it is converted to a boolean value according the the XPath 1.0 specification. In particular, if the XPath expression results in a set of objects, then 'test' is considered to be true if and only if the set is not empty.

If the 'test' XPath expression is not well formed, then an error results.

If this tag is not directly contained by a 'choose' tag, then an error results.
