Code Web Dynpro Save All Metadata

Hi Experts!!

I have a problem with SAP Netweaver when I go programming in web Dynpro.

When I go insert a code in tab "Implementation", for example:

Insert this code:

String headerText = "Congratulations ";

headerText += wdThis.wdGetCadastroPessoaController().wdGetContext().currentContextElement().getNome();

headerText += "!";

wdContext.currentContextElement().setNome(headerText);

Into to method:

public void onPlugFromCadastroPessoaView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

}

When I go Save All Metadata the code disappearing. Then I try click again in Save All Metadata Button, but the code don't stay there.

Anyone know why this happen?

Thanks in advance!
