Re: scomp problem: getPosList() is already defined in net.opengis.gml.LineStringType

Hi.
Question regarding this problem: if I compiled the GML schemas (which are causing the problem) with ANT where the javasource flag is not set and compiled other schemas that depend on GML (putting the GML-jar on the classpath) also with ANT but this time with the javasource flag set to 1.5...would this work? I mean would there be any problems or disadvantages using this approach? 

Regards,
Johannes

Hi Magnus

I think this is a bug.


Your schema imports feature.xsd which includes (via a long list of 
dependencies) geometryBasic0d1d.xsd which defines the LineStringType 
which is the cause of your first error.



The definition looks like this (where I’ve removed some annotations 
for readability):


<complexType name="LineStringType">

<complexContent>

<extension base="gml:AbstractCurveType">

<sequence>

<choice>

<choice minOccurs="2" maxOccurs="unbounded">

<element ref="gml:pos"/>

<element ref="gml:pointProperty"/>

<element ref="gml:pointRep">

</element>

<element ref="gml:coord">

</element>

</choice>

<element ref="gml:posList"/>

<element ref="gml:coordinates">

</element>

</choice>

</sequence>

</extension>

</complexContent>

</complexType>


I think the problem here is that you have _/both/_ a choice with 
minOccurs=”2” of an element referred to as “gml:pos” _/and/_ a 
separate element referred to as “gml:posList”. Since you can have more 
than 1 ‘pos’ from the choice, XmlBeans (under the –javasource 1.5 
flag) generates a method that allows you to get back the list of such 
‘pos’s called getPosList(). However there is also an element at the 
same level called “posList” so XmlBeans generates a different method 
called getPosList() to allow you to get this single element.


These 2 methods both have no arguments and hence they clash.


Unfortunately I don’t know of any “proper” way around this at the 
moment. You could edit your schema so that one or the other of the 
references is renamed – but you may not have control over the schema. 
Equally you could edit both the interface and impl files after they 
are generated to rename one of the methods. Or you can remove the 
–javasource 1.5 flag – in which case the generated code no longer has 
the first of those generated methods in it and there is no clash. But 
all of those seem a bit hacky. Hence I’ve raised a JIRA - 
http://issues.apache.org/jira/browse/XMLBEANS-225.


Sorry I don’t have better news.

Cheers,

Lawrence

Hi.


A am trying to compile this schema
