Are you sure you get a NullPointerException in line 386 containing

wdContext.currentContextElement().setCountry("US");

I don't believe this.

Armin

[Former Member]

Sorry it's in line 387

[Former Member]

OK, the variable inputRegion contains NULL. Why?

Armin

[Former Member]

That's what i am not getting, after all i am <b>passing</b> country code to import parameter of BAPI inputRegion.setI_Land1().

why at all it should throw null pointer here

is it error in R/3 side???

[Former Member]

Kind of a dumb check but have u created an object for the reference inputRegion

inputRegion = new bapi()

I know its a dumb check but just thought cos ur getting inputRegion = null.

[Former Member]

Can you show how the variable inputRegion is declared and assigned?

Armin

[Former Member]

//@@begin others

Z_Bapi_Ca_Regio_Input inputRegion;

//@@end

and in Customcontroller wdInit(){

inputRegion = new Z_Bapi_Ca_Regio_Input();

wdContext.nodeZ_Bapi_Ca_Regio_Input().bind(inputRegion);

}

any suggestion

[Former Member]

Can you select the variable "inputRegion" and do a Source -> Find Occurences in File?

Is there any place where you assign NULL to the variable?

Armin

[Former Member]

nowhere i am assigning null to "inputRegion" .
