Hi Experts,

I need to provide an option to upload image for some table records in a form. I followed the below link to achieve the same but it gives me an error saying Object reference not set to an object. Can anyone help me to find what is wrong in the code or is there any simple way to get it done.

https://jaipaljadav11.blogspot.com/2023/11/upload-image-file-in-form-grid-using-x.html

I believe the parameters are not being passed properly in the below code. can anyone help me to fix it please.

internal final class uploadImage
{
public void uploadImageFile(formRun _fromRun)
{
FormRun visualForm;
FileUpload fileUploadControl;
str imageFilePathName;

visualForm = classFactory::formRunClassOnClient(new Args(formstr(SysGetFileFromUser)));
visualForm.init();
visualForm.design().caption(/@ApplicationPlatform:GetFileImageCaption/);
fileUploadControl = visualForm.design().controlName('FileUpload1');
visualForm.run();
visualForm.wait();
FileUploadTemporaryStorageResult fileUploadResult = fileUploadControl.getFileUploadResult();
if (fileUploadResult != null && fileUploadResult.getUploadStatus())
{
imageFilePathName = fileUploadResult.getDownloadUrl();
}
if(imageFilePathName)
{
   formDataSource signaturetable_dss = _fromRun().dataSource(1) as FormDataSource;
   Signaturetable signaturetableLoc = signaturetable_dss.cursor() as Signaturetable;
   ttsbegin;
   signaturetableLoc.selectForUpdate(true);
   signaturetableLoc.Image =ImageReference::GetPackedBinaryData(imageFilePathName);
   signaturetableLoc.update();
   ttscommit;
}
}

public static void main(Args _args)
{
FormRun formRun = _args.formRun();
uploadImage object = new uploadImage();
object.uploadImageFile(formRun);
}
}

Hi @Alex,

You confirm that you've created a table with a container field for the image and that the names are correct ?
if not, I suggest you debug the image import class to see exactly where the error occurred.

Best regards,

Dear Mohamed,

Thank you for the reply. Yes I created the table with container field.

FormRun formRun = _args.formRun(); this is not working it seems. is this a valid code ?

public static void main(Args _args)
{
FormRun formRun = _args.formRun();
uploadImage object = new uploadImage();
object.uploadImageFile(formRun);
}

Consider whether you can't simply use document management; then you wouldn't need any development.

If you want to write custom code, there is a much easier way to get an uploaded file: File::getFileFromUser(). Also, use the stream directly (openResult()) instead of the download URL.

Anyway, when you get such an exception, you need to find where it's thrown. Then you can check why the object reference (such as a variable) is null instead of an actual object.

If you want to get the caller form, use _args.caller() instead of _args.formRun(). It assumes the class was called from a form (by a menu item button, most likely).

Hi Alex,

You have the ability to attach images to records using standard functionality. Wouldn't it work for your scenario?

Thanks,

Hi @Alex,

have you created a action menu item and assign it to the button ?

if yes make sure that the Copy caller query is set to yes

Thank you all for the inputs. All what I need is user should be able to attach image to each records in a form. the table and form are completely new and customized objects. This image needs to be printed / displayed in a SSRS report. Is it possible to achieve this by using document management ? if yes kindly let me know how to use it and bring the image in the report. Thanks.

Yes, document mnagement allows you to upload an image and attach it to a record. When developing your report, you can take the image from document management.

Here you can learn about document management.

Hi community member,

Just like any standard form, you click on the "attachment icon" for the selected record

Then you click new image

Regarding reports, maybe check if this link helps:

Hi,

Did you try to add new field for image like person image in HcmWorker form ? This is a standard form. You can do it on the same way and use it on your SSRS report, another example company image also.

Thanks,
