反应器不起作用

文字中有段代码，查看时都正确，却不能显示？


(defun show-l (notifier-object reactor-object parameter-list / p str el)
(setq p (nth 1 (reverse(vl-remove-if-not '(lambda(x)(= 10 (car x))) (entget(vlax-vla-object->ename notifier-object))))))
(setq str (strcat "X=" (rtos (cadr p) 2 3) "\\PY=" (rtos (caddr p) 2 3)))
(setq el (entget (handent (car (vlr-data reactor-object)))))(princ el)
(setq el (subst (vl-list* 304 str) (assoc 304 el) el))
(entmod el);更新文本图元表
(princ el)
(princ)
)
(defun c:rct-line(/ el rlt vrl v_l1)
(setq el(car(entsel "\n111")))
(setq rlt(list(vlax-ename->vla-object el)));将图元名转换为VLA对象
;创建对象反应器，回调事件是图元被修改，回调函数是show-l
(setq v_l1(list(cdr (assoc 5 (entget el)))))
(setq vrl(vlr-pers(vlr-object-reactor rlt v_l1 '((:vlr-modified . show-l)))))
(princ)
)
在程序中插入（princ el）

你这个反应器，是移动自身触发的条件。没有做过这种，感觉实现不了，vl-catch-all-apply错误处理判断都是通不过，返回值为#<%catch-all-apply-error%>

你可以自己画多段线这样实现，按你现在这种方法应该是没有问题的

打印出来的图元资料都是(princ el)得到的，而(entmod el)返回的是nil，即不能修改图元。
使用vla-put-textstring试了下，提示"对象正在通知"，猜测callback函数执行期间不能改变图元资料。
如果还是想用反应器的话，可以考虑用PL线和text/mtext。
