Message isnu00B4t display in messageArea

Hi All:

I have a view that is show in the portal. The problem is that instead display the message, just do a refresh but nothing else. Doesn´t show the message.

I put a messageArea and I wrote the following code:

IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();

if (wdContext.currentManModelElement().getImplemDate()== null){

msgMgr.reportException("É necessário prencher o campo Data início da implementação", false);

}

else if (wdContext.currentResponsibleElement()== null){

msgMgr.reportException("É necessário prencher o campo Responsável", false);

}

else{...}

Thanks
