Fixed with the change to a local variable for beanId changes and addition of release() methods. Fixed with change to using use a local beanId variable and addition of release () method. |
In the following jsp-fragment the bean is used in the latter <input:text> in spite of attribute bean="" in some JSP containers. This is because the beanId field of the input tags is changed to null if it was originally "". (There is a workaround: give an arbitrary value to the bean attribute. The workaround causes some unnecessary method calls.) <% Map map = new HashMap(); map.put("foo", "bar"); pageContext.setAttribute("map", map); %> <html> <head> <title>Test</title> </head> <body> <input:form bean="map" method="post" > <input:text name="foo" bean="" /><br /> <input:text name="foo" bean="" /> </input:form> </body> </html> A fragment from the JSP specification 1.2 (from chapter Tag Extension API - JSP.10.1 - Simple Tag Handlers - Properties): Once properly set, all properties are expected to be persistent, so that if the JSP container ascertains that a property has already been set on a given tag handler instance, it needs not set it again.
