Hi,

We want to have our Blackberry application running on 4.5, 4.6, 4.7 OS. 

When our application starts, we are having a check for all the 5 permissions, that our application needs.

If one or more of the permissions are set to 'Deny', we invoke the application permissions page

If user sets the required permissions, we proceed further. If user discards, we display the following alert dialog to user, and exit from the application - 

Dialog.alert('You have not set the necessary application permissions. The application is closing').

This works for all the permissions except for the 'Cross Application Communication' permission.

When this permission is set to 'Deny', and we start the application, as expected, we get the Blackberry dialog-  '<Appl> is requesting changes to its application control permissions',

followed by the permissions page.

If user discards the changes on this page, ('Cross Application Communication' is still set to 'Deny'),  we cannot show the following warning message to user, (before exiting from the App)  - 

Dialog.alert('You have not set the necessary application permissions. The application is closing').

 If this is invoked, we get java.lang.Error.

The Cross Application Communication permission, doesn't allow to diplay a dialog to user.  

Is it a limitation with Cross Application Communication permission?

Is there any way to avoid this exception/ any workaround to inform user, so that he should set the necessary permissions?

Please let us know if you have any inputs/ suggestions.

The actual error seen from the Event Logs is as follows. -

From where are you displaying the Dialog?  Can you post a code snippet?

[Kenjkelly01]

It does not look as though displaying a dialog is needed to cause the RIM java language exception error. In OS 4.7 I have the same issue if Cross Application Communications permission is set to Deny.  

Here is the log for the same error that i am seeing:

Hi,

I am facing the same problem. if you found the solution please post here. Thank you.

I have found these steps to work:

1) Make sure you remove any static references to PersistentStore, RuntimeStore or any other class that is not your own and might give an error without this permission. For me it was a static reference to a persistent store. None of these classes must be accessed before you request your permissions.

2) At this point a ControlledAccessException should still be thrown when you try and request the permission. However it should show this in the log trace:

| net_rim_cldc-22(4C94D16C)
|  ApplicationReasonManagerImpl
|  addReasonProvider
|  0x4FEE

So remove any reason providers from your request. and now the permission request should work.
