I have to put images in my report dynamicaly. I have the relative path to
the image. I tried to do it with "Dynamic image". In the book I read that
I should create a dataset, that includes the image field, so I created a
DataSet that have the column "image". I set the DataType to "Any". In my
DataSetEventHandler I do following:
File img = new File("/images/test.gif"); (the String should be a variable
later)
dataSetRow.setColumnValue("image", img);
In my report I create a table, insert the image item, select the dynamic
image and enter row["image"] as expression.
The result is a NullPointerException:
at
org.eclipse.birt.data.engine.executor.ResultClass.wasAnyType (ResultClass.java:462)
at
org.eclipse.birt.data.engine.script.DataRow.setColumnValue(D ataRow.java:152)
at
org.eclipse.birt.report.engine.script.internal.UpdatableData SetRow.setColumnValue(UpdatableDataSetRow.java:44)
Did I overlooked something.

I have found the solution for my problem. I selected the image from URI
instead of Dynamic Image, and the URI was "../.." + relativePath
../.. - i goes to directory 2 levels above
relativePath - is like "/images/test.gif"
