Zero '0' value in footer row is not visible
When my PHP script returns following line
echo '{"total":0,"rows":[],"footer":[{"tcName":"Total number of TC:","tcSlogan":0,"iconCls":"icon-sum"}]}';
In footer of my treegrid object I see only "Total number of TC:"
But when counter is not zero '0' then I see footer as expected
echo '{"total":123,"rows":[],"footer":[{"tcName":"Total number of TC:","tcSlogan":123,"iconCls":"icon-sum"}]}';
"Total number of TC: 123"
