#20 [Framework]update description from data path

[Garrigues Benjamin]

This function updates all descr nodes that print data
given in the path.
It could be usefull to integrate it into the js framework
(very usefull when combined with on_change() attribute)

function refresh_display_from_data_path(strPath){
var xmlDataNode = xml_selectSingleNode
(gform_XMLDATA,strPath)
var l_xmlDESCRNodesList = formDATA_selectDESCR
(xmlDataNode)
for(i=0; i<l_xmlDESCRNodesList.length; i++)
{
formDESCR_refreshDisplay(
l_xmlDESCRNodesList[i])
}
}

Any improvement welcome

Note :
Using this function in a on_change() call makes IExplorer
5.0 bugs (fatal error) when you click on a field being
updated within the on_change().
It does works starting from 5.5 version.
