I'm trying to create a PageFolder programmatically from a Script in ServerManager but the execution fails.

This is the part of the script where I try to create the folder (inspired by other answers in this forum):

StoreElementAgent storeElementAgent = context.requireSpecialist(StoreElementAgent.TYPE);

IDProvider parentFolder = storeElementAgent.loadStoreElement("content", PageFolder.UID_TYPE, true);

folder = parentFolder.createFolder("NewFolder"); // This is line 20, referred by the error message

folder.save();

And I get the following exception:

ERROR 26.07.2019 12:44:23.713{dNR=} (de.espirit.firstspirit.server.scheduler.ScriptTaskExecutor): error during script execution : de.espirit.firstspirit.access.script.ExecutionException: null : at Line: 20 : in file: inline evaluation of: ``__execute() { import de.espirit.firstspirit.access.AccessUtil; import de.espirit . . .

I tried to create a Page in content store instead and I had the same problem.

I configured my credentials in the Properties section of the script task in ServerManager.

I'm Administrator of the project and the server.

I assume I'm having a writing permissions problem but I can't figure out how to solve it.

Is there anything pending to configure to have write permission in scripts?

PS: Sorry if the question has already been asked but it's difficult for me to use the search in German.

Hi Andres,

I am not sure which FS Version you are using, but I can give some pointers anyway:

- The "StoreElementAgent" is part of the develop-api not the stable access-api, so it might not be accessible in your version

- Did you check if you actually have a valid "StoreElementAgent" or null?

- Did you check if you actually have a valid "parentFolder" or null?

- The function to create a new folder is here "createPageFolder" (and differs for other folder types).

Hope this helps,

René

Hi seegers​

It turns out the last one was the key.

StoreElementAgent & parentFolder were valid objects.

Now it's working with:

folder = parentFolder.createPageFolder("NewFolder");

There was a mistake in the method name, as you pointed out.

However, it was still failing.

Another problem seemed to be that the parent folder wasn't released.

And without:

folder.save();

Thanks for your suggestions and help!,

Andres.
