why : visible, command assigned tactions affecting cpu usage of application? 2 answers

i utilize tactionslists onupdate event enable or disable buttons in application. noticed cpu using 25% of capability. when remove code triggerd on event cpu usage still remains 25%. if unhook event cpu run @ expected 1%.

it seems onupdate event fires way many times. there way prevent behavior?

the vcl provides application.actionupdatedelay help in such situations. set non-zero value forcefulness delay between successive action updating.

however, might more prudent find out why action forcing endless repeated onidle conditions. if can stop doing there's no need update delay.
