Coldfusion 10 - Element [n] is undefined in a Java object of type class coldfusion.runtime.Array -

-

i upgraded system cf8 cf10 , have 1 bug i'm having problems tracking down. has remote api call gets json string , string gets converted query object. that's i'm coming across error:

element [n] undefined in java object of type class coldfusion.runtime.array. problem in function converts string query.

<cffunction name="cfjsontoquery" access="public" returntype="query" output="no">   <cfargument name="cfdata" required="yes" type="struct"/>   <cfset var local = {}/>     <cfset local.tmpqry = querynew( arraytolist(arguments.cfdata.data.columns) ) />        <cfloop index = "i" = "1" = "#arraylen(arguments.cfdata.data.data)#">          <cfset local.row = queryaddrow(local.tmpqry) />            <cfloop index="k" from="1" to="#arraylen(arguments.cfdata.data.data[i])#">              <cfset local.colname = arguments.cfdata.data.columns[k]/>              <cfset querysetcell(local.tmpqry,local.colname,arguments.cfdata.data.data[i][k],local.row)/>            </cfloop>            </cfloop>   <cfreturn local.tmpqry/> </cffunction>

anywhere json returns 'null' (i.e. "...","19107-3609",null,null,null,"...") error thrown. i've tried using isnull check if it's null in cfloop:

<cfif isnull(arguments.cfdata.data.data[i][k])>    <cfset arguments.cfdata.data.data[i][k] = 'i null'/> </cfif>

edit - here's simplified example - issue way newer deserializejson() works believe:

<cfset jstr = '{"success":true,"errors":[],"data":{"columns":["id","fname","lname"],"data":[[390132,"steve",null]]}}'/> <cfset cfdata = deserializejson(jstr) />   <cfloop index = "i" = "1" = "#arraylen(cfdata.data.data)#">     <cfset row = queryaddrow(tmpqry) />       <cfloop index="k" from="1" to="#arraylen(cfdata.data.data[i])#">         <cfset colname = cfdata.data.columns[k]/>         <cfset querysetcell(tmpqry,colname,cfdata.data.data[i][k],row)/>       </cfloop>   </cfloop>

i've tried sorts of tests empty string, isnull etc. , i'm still not sure how query object built if deserializejson returns:

[undefined array element] element 3 undefined in java object of type class coldfusion.runtime.array.

this seem work:

<cfset cfdata = deserializejson(returndata,'false') /> <cfset qrydata = cfdata.data />

this lets me use qrydata if normal cfquery.

you can check if element undefined using cf function arrayisdefined(array, elementindex)

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
