Actually SELECT tag in the controller has some predefined attributes. If we
want to specify any other html attributes, we need to specify them as
_attibutename = "attribute value". This code is translated into html code as
follows
<TAGNAME attributeame = attribute value> i.e., if there are any functions
specified as attribute value, those functions will not be executed but they
will literally be specified as the value in the html code. For the present
scenario,
SELECT("Andhra Pradesh","Delhi","Tamil Nadu",_name="state",
_id="States",default="Andhra
Pradesh",_onchange="ajax('{{=URL(r=request,f='getcities')}}',
['States'],'handle')",requires=[IS_NOT_EMPTY()]))
whill be translated to
<select name="state" id="States", default="Andhra Pradesh",
*onchange="ajax('{{=URL(r=request,f='getcities')}}',
['States'],'handle')"*>
<option>Andhra Pradesh</option>
<option>Delhi</option>
<option>TamilNadu</option>
</select>
In HTML, URL function doesnt exist and hence will not be executed and hence
the error. Hope I conveyed the message clearly :).
