Jquery easyui autocomplete combobox error -


good morning! i'm using jeasyui framework , have populated combobox on form json cities. when type search city, see inconsistent data , console error.

part of form:

<div style="margin-bottom:20px">   <input class="easyui-combobox" name="comune_azienda" style="width:100%" data-options="label:'comune azienda:',labelposition:'top',required:true,     url:'getcomuni.php',     method:'get',     valuefield:'id',     textfield:'text',     panelheight:'200px'     "> </div>

error console:

uncaught typeerror: cannot read property 'tolowercase' of null @ htmlinputelement.filter (jquery.easyui.min.js:14150) @ jquery.easyui.min.js:13808 @ function.map (jquery.min.js:2) @ _a60 (jquery.easyui.min.js:13801) @ htmlinputelement.query (jquery.easyui.min.js:14126) @ jquery.easyui.min.js:13370

thank advice.

the error self explanatory:

uncaught typeerror: cannot read property 'tolowercase' of null

you applying tolowercase() function on variable value null
