[Former Member]

Hi,

I am getting "StringIndexOutOfBoundsException: String index out of range: 19" error when I am trying to pass a value into a method in the component controller. Below are the exception details, please help!

Hi,

Could you tell me which is line no. 252 in this code as there are many substring function in there one of which is causing a problem.

Whenever you do a substring first check the length of the string. Check the length of both the strings on which you are calling the substring function

Harika,

check the condition if string length is greater than 40 and then write the below statements

String sObjectType = sRequisition.substring(10, 19);

String sObjectKey = sRequisition.substring(20, 40);

then your problem will be resolved

Thanks

Hi Murtuza,

The error line is the one below the bold one in the above code of mine.

And the wdThis.assign() is working fine. And I am not using any substring in my called method...

Hi,

Could you paste the code of your controller's method named callExecuteModelMethod?

public void onActionApprove(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionApprove(ServerEvent)

//Assigning values in the context node to the component controller context

wdThis.assign();

//Calling the model execution methods

wdThis.wdGetFinanceDOA_TController().wdGetContext().currentContextElement().setActionFlag("A");

wdThis.wdGetFinanceDOA_TController().callExecuteModelMethod(action);

wdThis.wdFirePlugToConfirm();

//@@end

}

This is the code that I am trying to run.

Are you shure you do not use substring in any other method? Look at the second line of your error message ...

maybe in this method: wdThis.assign()

Hi,

The line that you have highlighted should not give StringIndexOutOfBound. Did you try mapping the controller context to your view and then setting it as

wdContext.currentContextElement().setActionFlag("A");

Hi!

can you please post the code? i think you try to substring a string like test.substring(0, 19), but the string is only 18 (or less) characters long.

In this case you get an StringIndexOutOfBoundsException.

Regards,

Markus
