Using UUID in GWT?

[membersound]

Hi,

I tried using java.util.UUID on the client side to generate some unique id's for a list that will be placed into a CellTable.

Unfortunately GWT does probably not support UUID on the client side??
No source code is available for type java.util.UUID; did you forget to inherit a required module?

Or is it somehow possible to "inherit" UUID as the compiler tells me?

How about Document.get().createUniqueId() ?

No it's not (unless someone, somewhere provides an emulated version of it in some module that you could <inherit/>)

UUID is not emulated by GWT so you can't use it out of the box.

Take a look at http://concentricsky.com/blog/2011/mar/emulating-jre-classes-gwt if you want to emulate UUID yourself. The link also covers CustomFieldSerializers that are needed for GWT-RPC if you want to send UUIDs over the wire.

Out of the box you can only use all the classes/methods listed at:

That's not possible in my case, as I want my Foo class to have a already a unique id on instantiation. As I'm just displaying all Foos in my CellTable and not using any DTO, I cannot use Document there...

Take a look at the attached file. It works for me.

I hope it helps.

Thanks, I will have a deeper look at this lateron.
At the moment, as you said, I provides UUID emulation and works.
