[jxpath] Array Creation Problem

[puneet sharma <pu...@yahoo.com>]

Hi All,

I am trying to call createPath to create array type of
bean. I have registered my own AbstractFactory to the
context.

I am calling
jxPathContext.createPath("secondBeanArray[1]/thirdBean").
I have created the context using FirstBean. 

Method getSecondBeanArray() of FirstBean never returns
null it always return a array (may be blank if no
child bean i.e. SecondBean is added). 

Problem is createObject() method of my factory is not
getting called in this scenario even though there is
no SecondBean already added to FirstBean.

I debugged the problem and found that if
getSecondBeanArray() returns a null then only my
factory is getting called. But I can't return null
from getSecondBeanArray() method.

Is there any direct way to solve this problem ??

If not, is there any way if I extend some classes of
JXPath API and register those back?

I saw the code also of JXPath API. And found that
BeanPropertyPointer.createPath() is calling the
PropertyPointer to create the node only in case of
null.

Thanks
Puneet

Dear Puneet,

JXPath is designed to support both null and empty arrays.  If there is a 
problem, I cannot glean the what it is from the explanations you provided. 
Could you post a test case that illustrates the issue?

Thank you,

- Dmitri
