WebTML tags » [All condition tags]<tml:[All condition tags] isdefined ="item | variable">
Purpose:
Tests if an item or WebTML variable of the given name is defined
Description:
This attribute tests for all types of WebTML variables visible to the current code and for the items on the current context document.
It returns true if an item or variable exists with the given name, no matter what its content is. Setting a variable to null will still let this method return true for its name. You must effectively remove the variable, or let it run out of scope, to to let this method return false for a variable that once was defined.
