There is no current API that can answer the question "is dialogName a name of a valid dialog definition", nor is there any way to ask for all the defined dialog names. Both of those seem like they might be useful additions ... could you file an RFE in the issue tracker?

RE: How know if a dialogs exists?
Hi, really I need to know if I can start a specific dialog and not work on the current dialog. For example: Boolean DialogHelper.canIStartDialog(String dialogName) Or something else I can use to know if a dialog exists.

You can programmatically check which implementation is in use (basic versus SCXML) by checking the implementation class of the DialogContext object you get back ... safest way would be to get the class name as a String and check for a prefix of "org.apache.shale.dialog.basic" versus "org.apache.shale.dialog.scxml" versus something else. Are you writing an application that might be used with either implementation?

Are you writing an application that might be used with either implementation? Craig If there is a currently active dialog, then you will be able to retrieve the DialogContext instance for it like this (in 1.0.4): FacesContext context = FacesContext.getCurrentInstance(); DialogContext dcontext = (DialogContext) context.getExternalContext().getRequestMap().get("dialog"); if (dialog == null) { ; // there is no currently active dialog } The trunk code (that should eventually become 1.1.x) has a helper method to make this easier: DialogContext dcontext = DialogHelper.getDialogContext(); > > > Thanks in advance > > Mario Buonopane > Craig

Hi, I need to know if a dialog exists before starting it. Is there a way to know it using shale-basic?
