ADT: Web Dynpro view/window error "Failed to create the part's controls"

Question

Hi, all
Most of the things in my ADT work fine (e.g. programs, structures, domains), even the Web Dynpro Componentcontroller can be edited.
However, with Web Dynpro view and window I get this error message: "Failed to create the part's controls".
In SAP GUI everything works fine.
Why could this happen and what can I do?
My system details:
32-bit Windows 7
Eclipse Luna Release (4.4.0)
ADT from https://tools.hana.ondemand.com/kepler, according to these instructions:  SAP Development Tools for Eclipse.
SAP GUI 7.30, patch level 9.
SAP_ALL authorizations
Java: SE, version 7 update 60
Activated services (SICF): wdy_aie_vd_preview, toolsdocu, docu
The Java error log in Eclipse is quite long. It starts with:
java.lang.IllegalStateException: java.lang.IllegalArgumentException: No enum constant com.sap.adt.wda.controller.semanticfs.common.ControllerFileServices.ControllerObjectTypeEnum.WDYNWZ

As it is not popular to post long logs unnecessarily, I will skip the rest of it for the moment - let me know if it could help and I will post it.
Thanks for help!

Hi Ponraj,
note applied without any problem.
I'm still facing some difficulties accessing a WD component, maybe you could suggest me how to solve/proceed:
in Eclipse Luna, I can access now a WD but "Layout" tab doesn't work - HTTP 403 Forbidden - Service cannot be reached. I guess it's a missing configuration, could you help me out on this?
EDIT: This one is solved; I just missed to activate a service in SICF (WDY_AIE_VD_PREVIEW).
That Eclipse module however seems not to be very stable; I tried to open a standard SRM WD view (wd component /SAPSRM/WDC_DO_SOCO_GAF_1, view V_AO_SOCO_GAF_1) and that resulted in the message:
500 SAP Internal Server Error
ERROR: Conversion of type C LENGTH 255 to type TABLE OF DEEP_STRUCTURE not supported. (termination: RABAX_STATE)"
is there a way, from the Methods tab, to access directly to a particular method's implementation? The only way I found is going manually under the IMPLEMENTATION tab and CTRL+F with the method's name.
is there any way to access to a particular enhancement made on the WD? Using SapGUI, there's a special "vortex" button to switch on a specific enhancement, but under Eclipse I can't find the alternative command.
I know we're getting a bit OT with respect to the topic, anyway if there's a guide that could help clarifying my doubts please, share that documentation
BR,
M.
