BIRT Exchange Forum: BIRT Exchange Forum -> Michael's BIRT Blog

This blog series takes a look back at the past week in the forums, recalling how active they were and highlights some of the questions asked that seem to frequent the forums or other interesting topics. The forums have been CRAZY busy, it seems, this new year, so far! Many great questions and answers are being posted every day. As always, thanks to those users who help answer questions! It is a great help to the community!

The unanswered topic from last week is about passing parameters from JSF pages with Seam. The poster is having issues passing parameters to BIRT from their JSF pages. They're able to send static values, but not dynamic values. If anyone has encountered this issue or have a suggestion or solution, please post it in the thread!

The next topic for this week is summing two values from separate grids and displaying the sum in the report. One way to sum values from two different elements in a report is to use persistent global variables to store the values and then recall them and add them together where you want to display the sum. There are probably several ways that this can be done, but this is one of them. In this question, the poster also wanted to display the value before the elements the actual data is in. To do this, you can store the values in PGVs in your onCreate script and recall them in your onRender script to display the sum. You'll have to run the run and render tasks separately for this to work.

The last topic for this week is how to hide the details of a report based on a parameter. The poster had a grouped table with details. They wanted to be able to hide the detail section based on a user parameter. To do this, all you need to do is add visibility script to the detail row. A simple script is included in the thread that shows how to do so. The visibility settings can be found in the property editor of the element you're wanting to hide.

Again, this is just a small sample of what went through the forums this past week. For more questions and answers that have been posted, check out the forums.
