build:
<2.5.2.v20100210-0630>

steps to reproduce:
1. new a cube and chart binging to the cube
2. in data column binding, new a aggregation with expression and close
3. reopen the aggregation

actual result:

please check if it's the custom chart binding helper issue.
please add  an expression button for the expression combo.
fixed by adding java script checking logic for new expression, just like design ui did before.
reopen
fixed.
verified.
