WDDeploymentException Failed to load deployable object part 'IConsumerUsag

[Former Member]

Hi All,

I'm trying to implement Component Interface usage within a Dev Component. However I'm getting an Exception stating it is unable to load the deployable object.

- I've declared the used components with Lifecycle of manual

- Within my view controller controller Added the required controller usage necessary

- Created instance of the desired usage component <b>with and without</b> the Component name:

code snippet:

//@@begin onActionGetRootMessage(ServerEvent)

IWDComponentUsage comp = wdThis.wdGetIConsumerUsageComponentUsage();

if(comp.hasActiveComponent() && comp.isReferencing())

comp.deleteComponent();

comp.createComponent(wdThis.wdGetIConsumerUsageComponentUsage().getName());

wdComponentAPI.getMessageManager().reportSuccess(wdThis.wdGetIConsumerUsageInterface().getRootMessage());

//@@end

The initial exception that caused the request to fail, was:

com.sap.tc.webdynpro.services.sal.deployment.api.WDDeploymentException: Failed to load deployable object part 'IConsumerUsage', type 'Component' of deployable object 'demo.sap.com/consumer_dc'.

Thanks For the help

Thanks for the reply!

the component usage is part of the same dc "consumer_dc". Within the view controller I added the component interface that is utilized as a Used Component and the component controller usage.

So It is not two different DCs just one.

Within the Event Handler method onAction...() i created an instance of the Component usage :

"IWDComponentUsage comp = wdThis.wdGet<CompUsageName>Usage();"

Then checked if it was utiliezed or allready instantiated else where "comp.hasActiveComponent()" && "comp.isReferencing()". If so delete the instance "comp.deleteComponent()"

After that i create a new component instance "comp.createComponent()" and tried it this way "comp.createComponent("Component Name")"

Still no luck and keep getting the same exception.

Hi,

Can you try changing the option to "CreateOnDeman" in WebDynpro Component Usage.

Note: If you choose CreateOnDemand: You need not to create the instance for the Component in the code. The WebDynpro runtime environment creates the instance whenever it is required.

Hi Charan,

It won't let me change the Lifecycle of the used component. It defaults to manual.

Now I've created another DC called "provider_dc" and is in the dependencies for "consumer_dc" with permission set for "provider_dc" and "consumer_dc".

I'm still getting the same exception. It is interesting when i utilize the createComponent() method without specifying a component name as a parameter I get this exception:

The initial exception that caused the request to fail, was:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: No component implementation has been specified for ComponentUsage(IRootUsage, createOnDemand=false, inReferencingMode=false). (Hint: It can be specified as a parameter to the create() method, letting the component usage refer to a component implementation or via a component configuration.)

I've deployed the "provider_dc" before the "consumer_dc" also.

Hi,

Is IConsumerUsage Component is part of same DC which you are trying to deploy?

If not first check the other DC, that is consumer_dc deployed or not? If not deployed deploy that DC first.

If both the components are part of same DC that is "consumer_dc" then while adding the UsedWebDynpro Component what option did you select? is it CreateOnDemand/Manual? If you select manual, you need to create the instance for that ConsumerComp before you use it.

Hi,

How many DC's you have?

If you have two DC's and using one component in another DC then the below might be the problem:

Are you using IConsumerUsage component from other DC? If so, please make sure that you deploy consumer_dc before the other dc.

Jaya.
