Not able to change the FILELIST in Library

[OOCLLeoWu]

Hi,
I tried to load all the data source and replace their files to special one ANI.xml.

List<?> dsList = report.getDesignHandle().getModuleHandle().getAllDataSources();
for(Object obj : dsList) {
if(obj instanceof OdaDataSourceHandle) {
OdaDataSourceHandle ds = (OdaDataSourceHandle) obj;
ds.setPrivateDriverProperty("FILELIST", "ANI.xml");
}
}

In the main report, I found it worked.
But in the library, it will throw below exception when modify FILELIST.

org.eclipse.birt.report.model.api.IllegalOperationException: The module is read-only and operation is forbidden.

I found the library will be set to readonly by default in line 207 of class org.eclipse.birt.report.model.core.LayoutModule

try {
library = this.loadLibrary(includeLibrary.getFileName(), includeLibrary.getNamespace(), reloadLibs, url);
library.setReadOnly();
} catch (DesignFileException e) {
logger.log(Level.WARNING, e.getMessage(), e);
Exception fatalException = ModelUtil.getFirstFatalException(e.getExceptionList());
library = new Library(this.session, this);
library.setFatalException(fatalException);
library.setFileName(includeLibrary.getFileName());
library.setNamespace(includeLibrary.getNamespace());
library.setID(library.getNextID());
library.addElementID(library);
library.setValid(false);
library.setAllExceptions(e.getExceptionList());
}

But I does not find a method to change the library mode back to editable. Finally I have to use java reflect to change the property activityStack to class ActivityStack for editable mode.

List libLst = report.getDesignHandle().getModule().getAllLibraries();
for(Library lib: libLst) {
java.lang.reflect.Field field = ModuleImpl.class.getDeclaredField("activityStack");
field.setAccessible(true);
field.set(lib, new ActivityStack(lib));
}

I dont know if this way is allowed or any better workaround solution to provide? Thansk.

I do have the same issue starting with BIRT 4.17 (Worked fine in 4.16). If I try to add a XML file to the datasource like this:

...
getDesignHandle().findDataSource("Data Source")
      .setProperty("FILELIST", "myPath/myFile.xml");
...

I get the following exception:

...
org.eclipse.birt.report.model.api.command.PropertyNameException: The property "FILELIST" is invalid for element "Data Source".
	at org.eclipse.birt.report.model.command.PropertyCommand.setProperty(PropertyCommand.java:140)
	at org.eclipse.birt.report.model.api.DesignElementHandle.setProperty(DesignElementHandle.java:473)
...

I did not change anything in the rptdesign.

Did anything change concerning the usage of filelist with BIRT 4.17?
