GroupDocs.Assembly Product Family

Hi we have use case where we want power point template with placeholder and json data to bind to placeholder. I am testing your assembly product for this use case. My code is working for excel and word templates but not with power point could you please look into it and let me know if my approach is correct ?

Error while generating
java.lang.IllegalStateException: An error has been encountered at the end of expression ‘no…’. Can not get the value of member ‘no’ on type ‘class com.groupdocs.assembly.system.data.DataRow’.

@Test
	void groupDocPPT() throws Exception {
		String fileInputPath="src/test/resources/templates/Presentation.pptx";
		String fileOutputPath="src/test/resources/output/Presentation_out.pptx";
		String dataSource="src/test/resources/data/introduction.json" ;

		JsonDataLoadOptions options = new JsonDataLoadOptions();
		options.setAlwaysGenerateRootObject(true);

		JsonDataSource json = new JsonDataSource(dataSource,options);

		DocumentAssembler documentAssembler = new DocumentAssembler();
		documentAssembler.assembleDocument(fileInputPath,fileOutputPath,new DataSourceInfo(json));


	}

Hi I wanted to follow up on the above support ticket, I understand that you’re investigating on a solution, and I appreciate your efforts.As I am currently in the process of researching and evaluating libraries for our use case , it would be really helpful to have a sense of when a resolution or update might be available. This will allow me to determine whether the library can be utilized for my project or if I need to explore other options.

Could you kindly provide an estimated timeline for when I can expect an update or solution?

Thank you again for your assistance, and I look forward to hearing from you soon.

Could you please confirm the version of GroupDocs.Assembly you are currently using? We tested your scenario with the latest version (24.9.1) and were unable to reproduce the issue when using the following option:
options.setAlwaysGenerateRootObject(true);

However, we could replicate the issue in older versions of the library.

We recommend ensuring that you are using the latest version. If the issue still persists, please let us know, and we’ll be happy to assist further.

Thanks.

Hello, thanks for waiting, it looks like you are evaluating the GroupDocs.Assembly in trial mode and this is a side effect of the trial limitations.

Feel free to request a temporary license from this link. Temporary licenses are valid for 30 days.

The code below shows how to apply the license from a file.

License lic = new License();
lic.setLicense("GroupDocs.Assembly.Java.lic");

Please let us know if the issue still persists.
Thanks.

Hi , I was checking how to insert image in ppt with placeholder and came across
" At the moment, GroupDocs.Assembly does not support images in PowerPoint Presentation."
So is there a timeline for support of this feature ?
