Trying to re-add UPDATE and DELETE default buttons to a form

Question

I created a maintenance form by copying a form I use for inserting rows into a table. I deleted most of the form's default buttons.
Now I'm trying to add the UPDATE and DELETE buttons to the cloned maintenance form, with no luck. When I look at the source
for another maintenance form, the update button shows the following code:
<INPUT TYPE="BUTTON" NAME="FORM_TEST1_MAINTENANCE.DEFAULT.UPDATE_TOP.01" VALUE="Update" onClick="if (validateWWVM281(this.form)) do_event(this.form,this.name,1,'ON_CLICK','');">
The newly inserted UPDATE button's code is:
<INPUT TYPE="BUTTON" NAME="FORM_TEST2_MAINTENANCE.DEFAULT.UPDATE_TOP.01" VALUE="Update" onClick=" do_event(this.form,this.name,1,'ON_CLICK','');">
So...... I added the code "if (validateWWVM281(this.form))" (no quotes) to the button's ONCLICK area. The source code for the form now looks like this:
<INPUT TYPE="BUTTON" NAME="FORM_TEST2_MAINTENANCE.DEFAULT.UPDATE_TOP.01" VALUE="Update" onClick="if (validateWWVM281(this.form)); do_event(this.form,this.name,1,'ON_CLICK','');">
Note the semicolon after the IF statement.
Bottom line.... if I wish to add a button to a form to replicate teh functions of a default button, how do I do this?

Answer 1

In the PL/SQL Button Event Handler for UPDATE button select 'Update' and write the following code:
doupdate;
and for DELETE button select 'Delete' and write
dodelete;
You don't need any code in the OnClick for these buttons.
Hope this helps.
