I had the same problem a couple of months back. I found the answer in the WAS 6.40 forum. You have to match patches with the NWDS otherwise it wont work. However, if your WAS is patch 6 and you use NWDS <b>patch 6 and above</b> then youre ok..

Hi,

I guess you forgot to bind all of your UI elements to context attributes.

Am I right?

I have written a simple WebDynPro with a text box ("hello World"). IT gave me the same error. I am thinking that my NWDS dosent work with the WAS version i have. I have WAS 6.3 and using latest NWDS. Have any one faced the same problem?

[detlev_beutner]

Hi Arul,

you should <i>always</i> and <i>only</i> use the NWDS together with the corresponding WAS. Your problems may or may not depend on this, anyhow, please be sure to use corresponding versions. If your problem should stay also with this, please come back and report...

Hope it helps

Hi ArulRaja,

I have the same error with my first webdynpro app. How do you fixed ?

Regards from Mexico,

[detlev_beutner]

Hi there,

check your com.aramco.test.wdp.InternalClientInfo.<init> at line 43. There a java.lang.NoSuchMethodError occured for com.sap.tc.webdynpro.progmodel.context.Context.createNode.

Hope it helps; if not, post the coding around the exception throwing source.

Best regards

Detlev
