Webdynpro - Component usage gets lost when activating

Former Member — Wed, 16 Oct 2013 10:41:50 GMT

hi folks,

when activating a webdynpro view the usage of methods that are handling events (e.g. the click event of webdynpro ALV) looses the information about the component usage when we display the view in se80.

so the methods don't work after activating a view in eclipse.

we use AIE 2.7 backend 7.40

is this a known error, or a mis-configuration?

best regards

oliver

I can confirm this behavior, I just stumbled upon this myself.

This is a critical issue in my opinion - I cannot use an IDE if there's a possibility it screws up my developments...

Hi Oliver, Dominik,

We have fixed this issue in ADT 2.19 release. To get the fix you would also have to apply the SAP Note 1939612 into the R/3 system.

The Note is applicable for

7.31 SP7 and later SPs
7.4 and SP2 and later SPs

Please let me know if you face any further issues.

Sorry for the inconvenience and the delay.

Best Regards,

Raghuvira

New problem with that.

we have 2 used componentes e.g. of WDR_OVR, called OVS1 and OVS2 in a component controller.

OVS1 is used in a method as usage. OVS2 is not used for some reasons.

When activating in Eclipse, the system changes the usage from OVS1 to OVS2 - only at runtime the system dumps as OVS2-Event is not assigneds to a context-element but OVS1.

must be a bug of eclispe.

as nice as eclipse is, in combination with webdynpro we are facing really some problems, so from our point of view, the usage of eclipse with webdynpro-elements is at the moment not really useable, so unfortunately for webdynpro we still use se80.

it is not possible to implement this Note as there is no correction attached? only a link to an SP-Package? how should this be done?

we have ATD 2.24 and 740 SP3 on ERP ehp7

Hi Pavirta,

i tried but CL_ADT_WDY_CONTROLLER_UTIL UPDATE_EVENTHANDLERS is not automatically implementable.

the snote does not find a lot of code that has to be corrected, can you try this please, it is also not possible manually there is maybe still a problem?

e.g. this contextblock

ELSE.

"for custom controller

is not in our coding???

Hi Oliver,

I have investigated and found that there are many differences between both the code , one in your system and one in the note. If it is urgent would it be possible for you to do a manual fix from a text file which i will share in the note? Meanwhile I will try to resolve the note issue.

Pavitra

HI Pavitra,

we are facing another serios bug in webdynpro eclipse environment.

when adding a Field (input field with label), the system says on activating or save "INvalid Enumeration Type for Property of field" (i translated to English as we use german eclipse which says "Ungültiger Aufzählungswert für Eigenschaft von Element"). No more details just impossible to save the View.

we have installed the latest version of eclipse ADT (2.24) - this seems to be a bug in eclipse ADT not in the backend???
