QUESTION
How can I embed images into a Birt report to show images depending on if the result equals 1 or 0?
I’ve tried following the guide from:
http://birtworld.blogspot.com/2010/09/birt-image-report-item.html
I am not able to show an image (checkbox) when the column value equals 1 and another image (unchecked box) when the column value equals 0.
I’ve tried using the following expression:
...ANSWER
Answered 2021-Oct-12 at 08:03This is an expression, so you should NOT use a semicolon afteer the string literals. Furthermore, the value might be different from 0 or 1 (e.g. null), so you should also add yet another image filename for the "else" part.
In order to check that your images can be displayed at all, you should also use a constant expression as the very first step:

QUESTION
Lets say I have a table with a list of names, such as "a, b, c" and each name has several other values assigned (some of the other values can be assigned to several/all of names values, example below).
Table example:
( names - other ):
a - aa
a - ab
a - ac
b - ab
b - bb
b - cb
c - ac
c - bc
c - cc
How do I make in birt so that I could select names in one parameter box and get corresponding other values to select for another parameter? I know it's possible to do that with cascading parameter, but that doesn't allow to have multiselect for the first parameter, which in our example would be names values.

QUESTION
I would really appreciate some help with a computed column using an expression in Birt.
I have two columns which are giving results, one gives email addresses and one gives contact numbers: telephone, mobile..
When the email result is null then the contact number column shows a number, these are separate communication methods from a table in sql.
What I would like to do is create a new computed column for both the email address and the telephone number, when emailaddress is null then replace with contactnumber = contact and when contactnumber is null replace with emailaddress.
I've looked at a few similar questions online and found that entering the below script into the birt expression builder is accepted when you click validate, but it is not loading the report in the erp software I am using.
Is the expression itself correct?
...ANSWER
Answered 2021-Sep-20 at 06:58No, it is not correct (syntactically valid, though).
First of all what we've got here is an expression, not a function.
So there shouldn't be a return statement.
And obviously true cannot be right. The other values are (probably) strings, so this should be a string as well.
I'm not quite sure what you actually want to achieve. Maybe you are looking for something like COALESCE in SQL oder NVL in Oracle SQL?
I suppose you create a JS function, test it with JSfiddle or so, then place it in the initialize script and call it in the expression.

I'm working with PDF on tags for accessibility with iText7. I get PDF via BIRT's template from DB and can't to add tags there. Are there any ways in the iText7 to add tags automatically?
...ANSWER
Answered 2021-Jun-25 at 06:33I don't think that this is going to work. Generally speaking, you cannot add tags automatically to an existing PDF. So, as of now, BIRT cannot create tagged PDF.
QUESTION
In this example for multi-column sorting
...ANSWER
Answered 2021-May-31 at 13:41Initial point to remember: Column indexes are zero-based - so, column 0 is the first column you see in the table; column 1 is the second column - and so on. The column indexes are assigned when the data table is first created, based on the order in which they are defined in the HTML table (or in the DataTable itself).
The specific example:

I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:
first_job <- function(x) tail(x[!is.na(x)], 1)
first_job <- apply(data, 1, first_job)
...ANSWER
Answered 2021-May-11 at 13:56You can get the value which is next to last non-NA value.
QUESTION
I used Eclipse Birt Engine 4.4.2 (birt-runtime-4_4_2) in my project, And when i encrypt java classes with Jar2exe, even with not hiding "C:\fx.jar|META-INF*|com\javafx**" , Birt Engine class loader is not able to load report handler classes, Is there a way to pass this error?
...ANSWER
Answered 2021-May-02 at 05:20Problem: According to the solution provided by the jar2exe official website, Every class has a ClassLoader that loads the class.
The ClassLoader of protected (encrypted) classes, is a special ClassLoader, while the ClassLoader of unprotected classes is another ClassLoader. When the program is to load a class or resource, it will use the ClassLoader of the current class by default, such as "Class.forName()". So in the Eclipse Birt program is to load protected resource within an unprotected class, the ClassLoader of the unprotected class cannot load the protected resources. In this problem, the program tried to load ReportHandler class from an unprotected ApplicationClassLoader class.
Solution: When a generated exe file runs, The context ClassLoader of the current thread, is a Special ClassLoader. So we tried to download the source of Eclipse Birt Engine and then changed the body of loadClass(className) method of ApplicationClassLoader class and replaced the following line:

QUESTION
I have a BIRT report, which simply selects all the columns of a table. Every time a new column is added to the table I have to modify the report to visualize the new column. Is it possible somehow to show the result of a "select * from table" query in the report, so I shouldn't modify the report template anymore? The order of columns is not important.
Thank You.
...ANSWER
Answered 2021-Apr-06 at 08:35This is not directly possible. However, using the DE API, you can create and save a new rptdesign file based on the query, then in a second step execute that report.
The example at https://www.eclipse.org/birt/documentation/integrating/deapi.php only shows how to create layout items, but you can as well create Data Sources and Data Sets.
This is a bit tricky however, so unless you need this quite often, it is not worth the effort.
Here is an excerpt from a script I am using in a file sql2rptdesign.rptdesign to create a new report design. This should give you an idea:
