Strange problem with WD component build

[Former Member]

Hi all,

I have strange problem with building one wd component, which is part of SC. I'm getting few errors which stops me from building component (and transporting to other systems via CMS of course). I'm providing sample of the errors (3 types) and ant error:

[Error] Generation failed!

Error: Build stopped due to an error: [Error] Generation failed!

[/code]

Strange is that if I try to rebuild and deploy locally, no errors occurs and I can normally deploy and run application manually!

Does anyone have experience with this problem?

Thanks in advance!

Hi Ivan

I have faced this problem earlier BUT ultimately I have to create the DC from scratch.

But you can check these things:

1.Have you copy/pasted Dictionary type from other location (check the path of the dictionary types ) --> If yes then deleted that and create again(do not use copy/paste)

2.This also happens if your "Used DC" has some problems in the JDI --> Remove the used DC and add it again.

3.Make sure the NWDI infastructure is perfect- this may be a cause.

4. Check Context mappings --> delete all mappings > save metadata > Create again.

5. Delete the model and recreate it again.

6.If you have done reimporting model make sure to restart J2EE instance.

Hope this solves the problem - if not please post

Regards
