XPages EL: adding a condition to select field name -


i using sample database book "mastering xpages - second editon" (chap11e2b.nsf), created extended rich text editor. there managed bean used get/set field value. in sample, custom control using 

<mxpd2:inputrichtext id="inputrichtextextended"             style="width:100%" htmlfilter="identity"             htmlfilterin="identity" disablemodifiedflag="false"             htmlconversionwarning="nowarning">              <mxpd2:this.value><![cdata[#{rtebean['pagedocument.body']}]]></mxpd2:this.value> ...

i need check field know field use in control, standard "body" field or "bodyhtmlmime" in case document has flag (field called "converted") set "1".

how can done in el language, or how can use rtebean.['pagedocument.body'] in ssjs?

worst case create 2 controls , hid eacocrding flag, i'm sure not necessary sit can done @ data property level.

thanks :)

edit:

my code this:

<xp:text escape="true" id="bodyfieldname">     <xp:this.value><![cdata[#{javascript://sessionscope.bodyfieldname = 'pagedocument.body'; viewscope.bodyfieldname = pagedocument.getitemvaluestring("v2_convertedtomime") == "1" ? "pagedocument.bodyhtmlmime" : "pagedocument.body"; viewscope.bodyfieldname;        }]]>     </xp:this.value> </xp:text>  <mxpd2:inputrichtext id="inputrichtextextended"     style="width:100%" htmlfilter="identity" htmlfilterin="identity"     disablemodifiedflag="false" htmlconversionwarning="nowarning"     value="#{rtebean[viewscope.bodyfieldname]}">      <xp:this.converter>         <xp:converter             converterid="inputrichtextconverter">         </xp:converter>     </xp:this.converter>      ...

here error code:

inputrichtext's value has el because uses getter , setter of rtebean.

calculate field name , put viewscope variable.

use viewscope variable field name in el:

<xp:text     escape="true"     id="computedfield1">     <xp:this.value><![cdata[#{javascript:         viewscope.fieldname = document1.getitemvaluestring("converted") == "1" ? "document1.bodyhtmlmime" : "document1.body1";          ""}]]></xp:this.value> </xp:text> <xp:div themeid="container" style="width:800px">     <mxpd2:inputrichtext id="inputrichtext1"         value="#{rtebean[viewscope.fieldname]}">

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
