[regression] height/width/padding can't be saved in advance properties

build:
2.6.0.v20100531-0630

steps to reproduce:
1. new a report and insert a label
2. select the label, modify height/width/padding values in advance properties
3. click other place except property-self to save the modification

actual result:
height/width/padding can't be saved.
if i click height property after modifying height value, the modification will be saved.

expect result:
height/width/padding can be saved after clicking other place.
fixed it.

rollback the dimension cell editor behavior.
height/width/padding can be saved now.
