[FIXED] XDocReport can't display two image in generated document

Issue

I insert two image to template: "logo" and "background" But only background image presented in template.

I create ImageProdiver

private IImageProvider createImageProvider(IXDocReport ixDocReport, String fieldName, Blob image) {
    FieldsMetadata metadata = ixDocReport.createFieldsMetadata();
    metadata.addFieldAsImage( fieldName);
    ixDocReport.setFieldsMetadata(metadata);
    InputStream inputStream = null;

    try {
        inputStream = image.getBinaryStream();
        IImageProvider logo = new ByteArrayImageProvider(inputStream);
        logo.setUseImageSize(true);
        logo.setResize(true);
        inputStream.close();
        return logo;
    } catch (SQLException | IOException e) {
        throw new GeneralException("Error reading logo");
    } finally {
        if(inputStream != null) {
            IOUtils.closeQuietly(inputStream);
        }
    }
}

Create two Image provider

IImageProvider logo = createImageProdider(report, "logo", blobimage));
IImageProvider background = createImageProdider(report, "logo", blobimagebacground));

and insert to context in builder

context = this.report.createContext();
context.put("logo", logo);
context.put("background", background);

after generate document, exist only background image.

I do not understand why there is this problem, why only one picture is displayed.

How to solve this problem?

Solution

This is because you set FieldsMetadata to report two times. You need to create one FieldsMetadata metadata = ixDocReport.createFieldsMetadata() and add two image to it. Foe example:

 FieldsMetadata metadata = new FieldsMetadata();
 metadata.addFieldAsImage("chart1");
 metadata.addFieldAsImage("chart2");
 report.setFieldsMetadata(metadata);

 IImageProvider logo = new FileImageProvider(new File("path/to/image1"), true);
 context.put("chart1", logo);

 IImageProvider logo2 = new FileImageProvider(new File("path/to/image2"), true);
 context.put("chart2", logo2);
