xml load errors

hi,

i am trying to load an xml document and it shows the following 2 errors:

val.firstChild is null
getText()(cell)dhtmlxgridcell.js (line 176)
_fillRow()(tr.ev_light, Element 0=Subject ID 1=cell 3=cell 5=Integer)dhtmlxgrid.js (line 767)
_process_xml_row()(tr.ev_light, row)dhtmlxgrid.js (line 763)

render_dataset()(0, 21)dhtmlxgrid.js (line 835)

[Break on this error] : "");val=val.firstChild.data};if ((val||"").toString()._dhx_trim() == "")
dhtmlxgridcell.js (line 176)

this._fillers is undefined

init()()dhtmlxgrid.js (line 66)
[Break on this error] this.load(this.xmlFileUrl+getUrlSymbol(...(f[2]);this._fillers.splice(ind,1)}else

i am loading it with the following command:
grid.loadXML("../Views/TreesAndGridXMLs/QueryQuestionGrid_cf test occ.xml");

and i have noticed that it loads fine except when i had an xmlcontent tag for the coro cells, which of course i need to display the data. this works in other xm's but not this one so i am very confused. here is the xml:

Problem caused by using 
    <cell type="coro" xmlcontent="1"/> 
    <cell/> 

Grid expects that cell with xmlcontent attribute will have at least any content inside it.
To resolve issue - add some value to such cells,  or remove xmlcontent attribute from them.
