how to use FlashIsland.EVENT_BEGIN_UPDATE and FlashIsland.EVENT_END_UPDATE

[Former Member]

Hi All,

I am traying to get value from SAP into Flex component, i am trying to find out where exactly its filling up the array in Flex component and i am unable to figure it out. i am getting values into flex component i can see them but when i am debugging the same i am not able to find where its putting values into array in flex builder debuggin mode.

if anybody can explain me how to use FlashIsland.EVENT_BEGIN_UPDATE and FlashIsland.EVENT_END_UPDATE . i dont know if there is any documentation on the event available for FlashIsland class.

public function Search(): void{

var Objid:String = OBJID.text as String;

FlashIsland.fireEvent(this, "Search",{OBJECT_ID:Objid});

}

will appreciate any reply.

I have seen that there is some bug in the early versions of the FlashIsland library where the EVENT_*_UPDATE events don't work. I saw an internal note the other day that this was fixed in newer (and shipping) versions of the library.

The code for the registration of the event should be:

FlashIsland.addEventListener(FlashIsland.EVENT_END_UPDATE, handleEndUpdate);

However I find that the better approach is to use public GET/SET functions as the bindings to the Web Dynpro Context. This way you get Flex code that fires automatically whenever the Web Dynpro Context data changes. This would be the prefered way of passing "events" from WD to the Flex code.

Updated versions of the FlashIslands library get delivered via support packages to the application server.

I really can't say. What SP level are you on? Are you a Ramp-Up customer? The Islands functionality (and all of 7.01) isn't released G/A yet.

We are also using these two events to update our flash side data. Just one general question, is there any detailed document about how the island library works and how the WD framework inteacts and communicates with flash components via the island library? I'll really appreciate it if someone can help me find one.

Thanks,

Hi,

got similar issues with the events.

i want to update my flash only when the data in a table (from webdynpro) is changed. Instead the flash island refreshes every time the webdynpro is changed (e.g. when table is scrolled).

how can I achieve this ?

i tried with all the events, but they seem to fire always, no matter whether data have changed or not.

Any help is appreciated.

btw: What is meant by "use the public set/get methods"

Thanks

Marcus

It is normal for the FlashIsland to "refresh" on every server side event that occurs in Web Dynpro. If you only want to perform some particular action if the data changes, then you will need to store a local copy of the data and compair the before and after values.
