Dynamic Report creation

SukanyaM

Hi All, I'm new to BIRT. My requirement is this. A dynamic table is to be created to display the data provided as part of json input. I created a report parameter to receive json, parse the same and constructed a table based on a library reportItem in the beforeFactory() and based on the json record count created new rows using RowOperationParameters. My first question is, I'm not using a dataset at all, instead directly accessing the cells of a table and adding elements like label or data into the cells and populating the json input in the beforeFactory. Is this correct ? or is there a way by which I could bind it to a dataset and then use the dataset to populate the table ?? Please advice.

If you are not using a data set to generate your table, it might require more code to generate your dynamic table the way you want it.

There can be some other challenges when not using a data set (ex: not able to use export data), however there is no wrong way to accomplish the task.

If you were wanting to use the binding method, here are some example posts that demonstrate how to accomplish this:

 

Here is an example that dynamically creates a Data Set based on the results of a query and generates a dynamic table based on the Data Set results:

This example dynamically creates a Scripted Data Set which might be helpful with the JSON data:

@Matthew L. Do you happen to have the rptdesign file that you uploaded in the below forum? Looks like that the attachments didn't get copied when developer.actuate.com was shut down.
