This is in the nature os an "Is it plugged in?" response, but....

Is the idom_pbdom_builder object valid?

IF (NOT (IsNull (idom_pbdom_builder))) THEN

   try
        idom_pbdom_doc = idom_pbdom_builder.BuildFromString(ls_xml)

   catch (throwable e1)
        ls_exception = e1.getmessage()

        //KEB - Error importing xml
        Parent.SetRedraw(True)
        This.SetRedraw(True)

        return
    end try

END IF

Is the value of LS_XML valid?
I.E.: it's not null, not too long, and contains valid data.

Is "idom_pbdom_doc" a variable of the correct datatype for the return value?
Example:  the return value is a boolean and idom_pbdom_doc is a string.

Do you need to cast the return of the "idom_pbdom_builder.BuildFromString(ls_xml)" call?
Example:  In an OLE call, the return value is ANY so if you want to ssee the return code the entire call needs to be cast:      long   ll_rc
             ll_rc = Long ( ole_object_instance.SomeFunction() )

Is it possible to step into the call using the PB Debugger?


I'm running out of ideas here.

Hi Olan,

ls_xml is valid. It contains the same data the first time the window is opened and runs without error. It contains the contents of a couple tables in the database and doesn't change between the first and second open of the window.

Below is the contents of my xml:

idom_pbdom_doc is defined as an instance variable of type pbdom_document. Below is the declaration:

pbdom_document idom_pbdom_doc
pbdom_builder idom_pbdom_builder

I don't cast the return value from the BuildFromString call as i use it to parse the document in another function further down where i am expecting a value of type pbdom_object.

I can debug but i can't step into the BuildFromString call as it is a pbd.  Below is the quick watch for the exception caught from the BuildFromString call:

Thanks for your help,

Karen

Hello,

Is your Batch Authorization window loading an other .pbx file ?

If so, I had a similar issue :

1) first use of pbdom (loading pbdom.pbx file)

2) launch a treatement that loads another pbx file (a c++ solution)

3) second use of pbdom (exactly the same as first use)

=> 'Error calling method of a PBNI object' when calling BuildFromString Method

I found that's because my other PBX use a non unicode charset ! 

Operations to fix this issue for me are :

- Change charset to unicode in c++ project

- adapt c++ code to be "unicode complient"

- regenerate the pbx file

- import the new pbx file with "import PB extensions ..." of powerbuilder

- copy pbx file in my executable directory

Hope this can help somebody because it was realy complex to resolve it for me

Hello dear PB-folks,

In my case 'Error calling method of a PBNI object' occurs every time, when the XML-String to be decoded is too large.

PBDom_Bldr = Create PBDOM_BUILDER

IF IsValid(PBDom_Bldr) THEN
	PBDom_Doc = PBDom_Bldr.BuildFromString(ls_my_XML)
END IF

If ls_my_XML is something around ~100 MB, then BuildFromString throws this error, when ls_my_XML is e. g. 10 MB, then it works.

I looked into PBDOM_BUILDER documentation, but there is no hint regarding to a maximum size?!

What is the maximum size for BuildFormString?

Kind Regards,

Martin
