The tl:taskList and tl:task tags output a set of tasks to the response and are used as follows:
11. <tl:taskList>
12. <tl:task name="Mow the lawn" />
13. <tl:task name="Feed the dog" />
14. <tl:task name="Do the laundry" />
15. </tl:taskList>
The tl:task tag supplies information about a single task while the tl:taskList tag does the final output. The tag handler for tl:taskList is TaskListTag. The tag handler for tl:task is TaskTag. Both tag handlers extend BodyTagSupport. Which allows the tl:taskList tag to get the task names from its nested tl:task children?
A. It is impossible for a tag handler that extends BodyTagSupport to communicate with its parent and child tags.
B. In the TaskListTag.doStartTag method, call super.getChildTags() and iterate through the results. Cast each result to a TaskTag and call getName().
C. In the TaskListTag.doStartTag method, call getChildTags() on the PageContext and iterate through the results. Cast each result to a TaskTag and call getName().
D. Create an addTaskName method in TaskListTag. Have the TaskListTag.doStartTag method, return BodyTag.EVAL_BODY_BUFFERED. In the TaskTag.doStartTag method, call super.getParent(), cast it to a TaskListTag, and call addTaskName().
E. Create an addTaskName method in TaskListTag. Have the TaskListTag.doStartTag method, return BodyTag.EVAL_BODY_BUFFERED. In the TaskTag.doStartTag method, call findAncestorWithClass() on the PageContext, passing TaskListTag as the class to find. Cast the result to TaskListTag and call addTaskName(). TaskTag.doStartTag method, call findAncestorWithClass() on the PageContext, passing TaskListTag as the class to find. Cast the result to TaskListTag and call addTaskName().
