Component Usage DEMO Does Not Have an Active Component

[Former Member]

Hi all,

I am getting the following error while accessing a method from one component to another..

ERROR : Component Usage DEMO Does Not Have an Active Component

In the component1 of a method i am having a success message .. i am calling that method from another component Component2..

While executing the component2 I am getting this error.

Can anyone help me out of this error.

Ragards,

Hi,

Create instance for the component using pattern. Instance for the used component is NA.

Hi,

you are getting this problem because,you might not have the active component that is reused...This means the second component from which you are calling the method....it should be in the running mode.....

hi,guy

you must create a IF_WD_COMPONENT_USAGE.

LO_INTERFACCONTROLLER TYPE REF TO IF_WD_COMPONENT_USAGE,

LO_INTERFACECONTROLLER TYPE REF TO ZIWCI_DYLAN_SUBCOMPONENT(called component interface name)

LO_INTERFACCONTROLLER = WD_THIS->WD_CPUSE_ZDYLAN_SUBCOMPONENT( ).

IF LO_INTERFACCONTROLLER->HAS_ACTIVE_COMPONENT( ) IS INITIAL.

LO_INTERFACCONTROLLER->CREATE_COMPONENT( ).

ENDIF.

HI,

calling the method in action handler, wdodoinit how does it differ...are you passing any thing to teh plugs..while navigation

Regards,

Lekha.

[Former Member]

No, I have not used any plugs since I am not calling any views from that component1.

I am just calling a method from that component1 to component2. I am accessing a node from that component1 and using that node in component2.

Have you tested the comp1 independetnly

check if there are any errors in it at design or at runtime..

[Former Member]

Ya Its working perfectly. If there is any error in component1 how will it work when i call the method in my action button..

after doing all the usages addeed try to save the applciation..then check for error...somewhere you might be doing wrong as it is not a runtime error right..

[Former Member]

have you isntantiated the used compoenent...

Wehn added as a usage under properties tab of component then you must also have it under the properties fo both the component controller and in the view whtere you are trying to access the methods...

I guess you might have not done this...
