Customize the ItemId lookup

Hi All,

I created a new lookup form.

My new lookup form should replace the item lookup using coc.

I tried coc in the base class of the item lookup.

I just take the coc and put info on it.

But its not working.

The break point also not hit in the coc and also in the standard class InventItemIdLookupSimple.

[ExtensionOf(classStr(InventItemIdLookupSimple))]
final class InventItemIdLookupSimple_Extension

public static void lookupItem(FormStringControl _ctrl, boolean _showOnlyWHSEnabled )
{

info("InventItemIdLookupSimple 1");

next lookupItem(_ctrl,_showOnlyWHSEnabled);
info("InventItemIdLookupSimple 2");
}

is this the base class for itemlookup? or something else.

Could you tell me where i have to take coc to change the itemlookup to my new lookup form.

Thanks

Hi john,

I think you might have several problems here.

- Your debugging setup might not be correct - please search for existing discussions or post a new question if you need help with it

- Your code prints two lines to infolog, but you wrote that you want to replace the lookup logic. Therefore I assume you didn't share your actual code with us. But your current code should print some infolog when it's run - so if it doesn't do it, then you're not extending the correct place.

- I don't think that you can replace the existing lookup with Chain of Command. But you can do it with an event handler, and FormControlCancelableSuperEventArgs

I don't think there is a class behind the ItemId lookup (at least I couldn't remember).

I am sharing the version that Ievgen made with the event handler.

Edit: I couldn't remember when you said class. I think you are talking about form

You can check the link below for the coc version. It's not exactly true, but the logic is correct. With Control's registerOverrideMethod method, he override the original lookup and called his own lookup. I haven't tried it but it seems correct.

Hi Nikolaos,

Thanks for the reply,

I did it by using event handler onlookup method for a particular itemid control in a particular form.Its working fine.

But i need to make my lookup form as a default form wherever the item id lookup control is.

Could you tell me the class which i need to use the eventhandler to make my lookup form as default.

Hi john,

this would require that you could replace the logic of the existing lookup class (InventItemIdLookupSimple). You can't replace standard system logic with extensions - unless the system specifically grants this in some scenario (for example [Replaceable] attribute).

So it's possible that your requirement can't be solved without adjusting every single lookup field separately.
