Message box from StiWebDesigerHandler implementation

[sduchampt]

Hello,

I would like to manage message when saving my report.
The only way I found is to throw a RuntimeException in StiWebDesigerHandler implementation :

Code: Select all

public class WebDesignerHandler implements StiWebDesigerHandler {
    public void onSaveReportTemplate(StiReport report, StiRequestParams requestParams, HttpServletRequest request) {
        throw new RuntimeException("Error message from onSaveReportTemplate");
    }
    ...

download/file.php?mode=view&id=24379&am ... 59f30b6b56

Is it the best way to display a message ?
I would like to have carriage return in my message, is it possible ("\n" has no effect) ?
With a RuntimeException, I can only display error message, how can I display a warning or an information message ?

Thanks for your help

Hello,

Please check the following code:

Code: Select all

protected void StiWebDesigner1_SaveReport(object sender, StiSaveReportEventArgs e)
    {        
        StiReportResponse.ResponseString("{\"infoMessage\":\"Report saved successfully <br> next line <br> next line \"}", "application/json", false);
    }

Thank you.

Hello,

Thanks for your response.
I can't find any method StiReportResponse.ResponseString...
I tried with StiReportResponse.responseBuffer

Code: Select all

public class WebDesignerHandler implements StiWebDesigerHandler {
    public void onSaveReportTemplate(StiReport report, StiRequestParams requestParams, HttpServletRequest request) {
        // throw new RuntimeException("Error message from onSaveReportTemplate");
        StiReportResponse.responseBuffer(response, "{\"infoMessage\":\"Test\"}".getBytes(), "application/json", false, null, false);
    }
    ...

When running (inside Tomcat9), I have this error (the output buffer seems to be closed) :

Code: Select all

Is there other possibilities instead of "infoMessage" ? Perhaps errorMessage, warningMessage ?

Thanks

Hello,

That code as a sample, you can use the similar code for Java version.

Thank you.

Hello,

I agree, it's the reason why I used StiReportResponse.responseBuffer.
But it's not working, I get an error (present in my last post)

Thanks

Hello.
Unfortunately, for Java version in onSaveReportTemplate(StiReport report, StiRequestParams requestParams, HttpServletRequest request) no HttpServletResponse object.
It's impossible to send message when saving report.
