Error message setting 'Multiline'

[Alexandra]

We are having problems with a report that we have created.
We cannot print or save it as a PDF.

The error message is “Cannot set properties of undefined (setting 'multiline').”

Therefore, we have upgraded Stimulsoft for our customer.
But there has been no improvement. We still get this error.

I thought I would try using a report which has worked perfectly for years.
However, I am now getting the same error when using this document.

Could you please help me by letting me know what the problem is?

Please see enclosed both json files

Hello,

Could you please clarify whether you are exporting the report from code or directly from the report designer?
Also, please send us a sample report(.mrt file) with test data that will allow us to reproduce the issue on our side.

Thank you.

[Alexandra]

We are exporting from the report designer.

I cennot tell if there is a possibility to get a mrt file.
But I will contact our developers if we have something like that.

Are these the files you are looking for?

[Max Shamanov]

Hello.

We have reproduced the issue and need some time to improve it.
We will notify you as soon as we have the results.

Thank you.

Hello.

We have successfully implemented an improvement.
Please check our next build 2026.3.2, when it becomes available.

Thank you.

Does this really mean, the reports that I have sent in cannot be used?
I have to update a system, that can cause me severe issues afterwards just to get a report, that is needed now instead of later?

Ok. Thank you. This is very unfortunate.

But we are not going to update our system in the near furture.

I just did it for testing and reversed it, because I found issues which I have to investigate first.
Issues I do not want to work with.

Hello.

OK. You can upgrade whenever it is convenient for you.
We identified that the issue was caused by the Editable property being enabled for certain report components.
When these components were used together with a signature, the error was triggered.

Thank you.
