sapui5 - Data binding not working in oData BaseType -


i'm trying binding odata list using mock server.

my metadata.xml is

<edmx:edmx     xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"     version="1.0">     <edmx:dataservices m:dataserviceversion="2.0" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">         <schema xmlns="http://schemas.microsoft.com/ado/2008/09/edm" namespace="gwsample_basic" xml:lang="en">             <entitytype name="equipment" basetype="gwsample_basic.equipmentbo">             </entitytype>                <entitycontainer name="defaultcontainer" m:isdefaultentitycontainer="true">                 <entityset name="equipmentset" entitytype="gwsample_basic.equipment"/>             </entitycontainer>             <entitytype name="equipmentbo" basetype="gwsample_basic.baseentitybo">                 <property name="code" type="edm.string" nullable="true"></property>             </entitytype>             <entitytype name="baseentitybo" abstract="true">                 <key>                     <propertyref name="id"></propertyref>                 </key>                 <property name="id" type="edm.string"/>             </entitytype>         </schema>     </edmx:dataservices> </edmx:edmx>

equipment.json:

[   {     "id": "1"   },   {     "id": "2"   },   {     "id": "3"   } ]

but appear this:

enter image description here

when add key:

<entitytype name="equipment" basetype="gwsample_basic.equipmentbo">     <key>         <propertyref name="id"/>     </key>     <property name="id" type="edm.string"/> </entitytype>

it works fine:

enter image description here

also, found createkey produce error：

odatamodel-dbg.js:2005 uncaught typeerror: cannot read property 'propertyref' of undefined

this.getmodel().createkey("equipmentset", {     id :  "111" });

so question is, can fix without changing odata metadata? key defined in baseentitybo.

this question duplicate of openui5 issue #951.

unfortunately datajs, odata library using in sapui5, not support derived entity types. used feature, there no plans support this.

it seems problem can solved backend service.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
