CMS modify existed object

Hi,

In CMS, I have created a customized table control and save data to customized table.

I used a customized EVENT_DSAVE function module to do this.

When I create a new object, after I click SAVE button, the system will run into my EVENT_DSAVE function module.

In that function module, I save data to database table.

However, when I am in change mode, after I click SAVE button, the system will not go into this EVENT_DSAVE function module.

I am wondering if there is any way to solve that.

Thank you.
