It seemed load indicator on paged grid toolbar not stopping when empty resultset returned. I use XMLDataModel to retrive data。When there were some data returned, load indicator behaved as expected.
When no data returned, it keep running.
Here are two example xml files, one with some date, the other empty:

<xml>
<results>
<TotalCount>201</TotalCount>
<item>
<name>accounttest</name>
<email>accounttest@mkt.wayway.cn</email>
<date>2006-11-9</date>
</item>
<item>
<name>accounttest2</name>
<email>accounttest2@mkt.wayway.cn</email>
<date>2006-11-10</date>
</item>
</results>


<xml>
<results>
<TotalCount>0</TotalCount>
</results>

Thanks!
