Changing the Default Text for Missing Dynamic Images in BIRT Reports

Creating dynamic reports in BIRT (Business Intelligence and Reporting Tools) can bring your data to life. However, one common issue that BIRT users encounter is the display of default text when images fail to load. Instead of seeing a helpful message, users might be confronted with "The resource of this report item is not reachable." Fortunately, there’s a straightforward solution to modify this default message for a more user-friendly alternative, such as "Image not found." In this guide, we will walk you through the steps to achieve that.

Understanding the Problem

When you include dynamic images in your BIRT reports, it’s possible for the images to become unavailable or unreachable. This often happens if the image source URL changes or the image is deleted. Instead of providing a useful message to users about the missing image, BIRT shows a default error text that can be deemed unhelpful. Customizing this text can enhance the user experience, ensuring clarity and professionalism in your reports.

Step-by-Step Solution

Here’s how you can change the text displayed for missing dynamic images in BIRT reports:

1. Access the Properties Tab

Select the Image: Click on the dynamic image in your report.

Open Properties: Navigate to the Properties tab, which is usually located on the right side of the BIRT design interface.

2. Setting the Visibility Attribute

Check Visibility Options: To handle the visibility of the image effectively, start by locating the Visibility attribute within the Properties tab.

Hide Element for Missing Images:

Check the Hide Element option.

Input the expression that defines when the image should be hidden:

3. Adding a Label for Missing Images

Create a New Label:

Place a new text label component on your report where you would like the message to appear.

Customize this text to say "No Image" or your preferred message.

Set Visibility for the Label:

Go to the Properties of the newly created label.

Again, check the Hide Element option.

Set the condition for the label to display only when the image is present:

4. Adjusting Layout

Add Padding: To ensure that your report looks neat and that other data elements remain properly aligned, you may need to add padding to the bottom of the "No Image" message. This adjustment is crucial to maintaining a clean layout.

Conclusion

By following these steps, you will be able to replace the default text of missing dynamic images in your BIRT reports with a more user-friendly message. Not only does this improve the presentation of your reports, but it also provides clarity to users who come across missing images.

Don't underestimate the value of good communication in data reports. Small changes, such as adjusting the way missing information is displayed, can make a significant impact on user experience and overall understanding of the report.

With this guide, you should now be able to modify your BIRT reports confidently. Happy reporting!
