test build:2.6.0.v20100329-0630

steps to reproduce:
1. get attached from bug #276216
2. open liba.rptdesign report, check no label style shows in layout
3. drag table from libb to report layout, change namespace to libc, click ok.

expected result:
in step2, label should has background style

current behavior:
label background style only shows after step3 and undo step3 will keep the background style
it is not a bug.
