Re: [emf-dev] Feature Not Found Exception While loading XMI resource

Sandeep,

Please ask questions using the newsgroup.  Without seeing your model it's hard to comment but it sounds like you have a non-containment feature for which you are passing an instance where the feature is serialized as if it were containment.   A containment feature will physically nest the instance whereas a non-containment feature will reference the instance contained elsewhere.

[emf-dev] Feature Not Found Exception While loading XMI resource





Hi All,
       I have a XMI resource as shown below

<?xml version="1.0" encoding="ISO-8859-1" ?>
<com.bosch.galaxy.re:Project xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:com.bosch.galaxy.re="http://www.bosch.com/galaxy/re" name="Tests_from_mko">

<Requirements  name = "TEMP_Top" id = "17691" description= "" CustomerProtected = "false" FeatureType  = "MANDATORY">
 <Requirements  name = "TEMP" id        = "17815" description  = "" CustomerProtected  = "false" FeatureType  = "MANDATORY">

    <Requirements  name = "Complex Drivers1" id  = "17893" description  = "" CustomerProtected  = "false" FeatureType    = "MANDATORY"/>

    <Requirements  name = "Complex Drivers2" id  = "17894" description  = "" CustomerProtected  = "false" FeatureType = "MANDATORY"/>

    <Requirements  name = "Complex Drivers3" id  = "17895" description  = "" CustomerProtected  = "false" FeatureType = "MANDATORY"/>

  </Requirements>
</Requirements>
<…..Project>

It s giving Feature Not found Exception : CustomerProtected Feature not found. (It is written in Log file.)
It looks as follows

Wrapped exception

And it is displaying only 3 nodes,
       Project
               Temp_Top
                       ComplexDrivers1

Whereas If I use the reference in XMI file it is displaying all the nodes with out any exceptions in Log file.

<com.bosch.galaxy.re:Project xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:com.bosch.galaxy.re="http://www.bosch.com/galaxy/re" name="Tests_from_mko">

<Requirements  href = "">
<…..Project>

And Temp_Top.re looks as follows

<com.bosch.galaxy.re:Requirements  name = "TEMP_Top" id = "17691" description= "" CustomerProtected     = "false" FeatureType  = "MANDATORY">

<Requirements  href = "">
</com.bosch.galaxy.re:Requirements>

Similarly the Temp.re file has references to other child files present in it.

Could, Anyone please tell me what is happening here.
If I use references in XMI file it creates unnecessary nodes and I don’t want those nodes to be created, I want only one node as root node, Can anyone suggest me to have such a tree structure.

Thanks in advance
