Dear Expert,

I am a beginner with B4x and have minimum knowledge in Java. I come from MS Access, VBA and VB6 background. I am now trying with B4j, I am sure it is very very good and appropriate for me to upgrade to web and app application development.

I am now stuck in next report of lesson 6. I have installed/put everything as instructed by Harris in the lesson, but when I try to run the report (vehicle list) from the Application/Report Pages, when I choose PDF and Run Report, nothing happens, next report page remains blank. When I choose html, the application crashes, I have made some screenshots, show below. Please advise, where is my mistake!

Sorry DonManfred, I think the textual explanation of problem, as I put above the pictures, should give understanding of problems. But I was doubt how to give more information, of course I could put in the attachment, so that it does not look too overwhelmed. The code I use here is exactly from the Lesson 6 from the ABMaterial] For Dummies (beginner lessons), I am just trying to run it, learning from it and see how it works. But unfortunately, this time I can not get it worked, I don't know where is my mistake.

Sorry for inconvenience, I will start describing problem again:

I am now stuck for the next report of lesson 6. I have installed/put everything as instructed by Harris in the lesson, but when I try to run the report (vehicle list) from the Application/Report Pages, when I choose PDF and Run Report, nothing happens, next report page remains blank.

I am now stuck in next report of lesson 6. I have installed/put everything as instructed by Harris in the lesson, but when I try to run the report (vehicle list) from the Application/Report Pages, when I choose PDF and Run Report, nothing happens, next report page remains blank. When I choose html, the application crashes, I have made some screenshots, show below. Please advise, where is my mistake!

I dont know what could be wrong. My example is rather simple. Have you tried with your own example from what you have learned from the lesson?

NextReports has always worked great for me. Very light and does the job, even for complex reports.
