Need Help on showing custom error message in BIRT report [message #1246034]

Hi,

I have a BIRT report (.rptdesign file) with "Begin Date" and "End Date" as input parameter. I want to restrict the user to view only 1 month data. I have used the following code in the "validate" script of end_date input parameter.

if(DateTimeSpan.months(params["begin_date"],params["end_date"]) == 0){
true;
}else{
false;
}

This works but it does not tell user that he is allowed to view only 1 month data.
Instead it showing this message "org.eclipse.birt.report.service.api.ReportServiceException: The validation for parameter "end_date" fails.".Also the exception stack trace is shown to the user.

Whereas I want to show a custom error message to the user in the else block. The custom error message that I want to show is "Max allowed duration for the report is 1 month only".

If anyone could kindly tell me if at all it is feasible in BIRT or not
OR
otherwise kindly let me know what is the recommended way of showing error messages in BIRT reports?

I need this urgently. Hence will really appreciate any quick help. Thanks.

Just Ask the user for one date: 'Please enter a date in the month to be
shown', then no error message is needed.

Hi Colin,

In my case, the requirement is User should have the flexibility to specify the begin date and end date for the report as there are cases when user may want to see data for any duration less than a month (e.g.3days/4days/7days/15days/26days).

But only in cases, when the duration is more than 1 month, then User should be shown an error message "Max allowed duration for the report is 1 month only".

Could you kindly suggest how can I show custom error message to the user in those cases when the duration exceeds 1 month? In other words, I wanted to know whether it is feasible or not in BIRT to show a custom error message to user? If feasible, then what is the recommended way implementing the same?

Thanks in advance.

Hi Sarmistha ,
Although there is no provision of showing a run time dialogue box in BIRT to satisfy the requirement, here is the work around Rolling Eyes

1. Create a global variable in initialize() method.
2. Create a label in the report.
3. Write your logic of if else in the onCreate() method of the label and display the error message.

If the logic fails and else block executes Very Happy

, the report won't run for more than 1 month and it'll immediately throw the error in BIRT viewer.

Hope this helps!!

Thanks,
Kushal Cool
