Hi Mario,

A user reported he tried to use this in screen fragment, but failed with error:

From the source I understand that this add-on doesn't support fragment, do you have a plan for this, or if you can suggest how to change?

If you enter a File Name the select a file to upload the Name clears. Could it perhaps leave the name but if it is empty add the name of the file to the Name text box?

Support drag and drop files

In ddca_EntityAttachmentsFragment can create and edit open in dialog mode?

When you attach a file, the following error is generated

Hello Mario,

I just found out about cuba platform and its possibilites - along with the marketplace. Your "Attachable" component seems very useful. However I noticed that it does not support MySQL yet. Are there any plans to include MySQL as well further down the road?

Best,
Uwe

It would be good to have a multi-upload option as well as the single file upload.

Also a dragzone for dragging file for upload might be a nice touch.

Support latest version of the framework 6.9

Hi Mario -

Thank you for the great work on this component. I have run into an issue with this component that I would like to bring to your attention.

In my project, I use this component on a Table alongside the "Add to Set" (https://doc.cuba-platform.com/manual-6.9/folders_pane.html) functionality of the platform. In this scenario, when I select a single row in the table and hit "Search" on the filters panel, I receive an ArrayIndexOutOfBounds Exception. It is important to note that no exception is received when a row is not selected and the Search button is clicked.

In tracing this exception, I have found that the issue exists on this line:
https://github.com/cuba-platform/cuba/blob/2a3d0a97ba475ce31c00e018161575d623614e85/modules/gui/src/com/haulmont/cuba/gui/components/filter/FilterDelegateImpl.java#L1967

The platform code is looking for the size of the "actions" array on the table and attempting to add the "Add To Set" action to that array per this line of code:

https://github.com/cuba-platform/cuba/blob/e70a3bb1660e836fe7e6313d8825ec350796d1f7/modules/web/src/com/haulmont/cuba/web/gui/components/WebAbstractActionsHolderComponent.java#L109

In my scenario, the following actions exist on the Table:
Create create (0)
Edit edit (1)
Remove remove (2)
System Information showSystemInfo (3)
attachment (4)
Add to set filter.addToSet (5)

The Exception I receive has the following text; IndexOutOfBoundsException: Index: 5, Size: 4

I suspect that this is because somehow, the component's action is not registering properly (I am not too sure about this).

I am interested in your thoughts on how I can fix this. I attempted to look through the component's code and wasn't able to readily identify the issue. My hope is that you have an insight that can help resolve this issue for me.

My suspicion is that moving the code from init to ready in this block should resolve the problem:

For your reference, the full stack trace is listed below:

Currently it's only possible to attach files from the browse, add the ability to do it from the editor.

hello!
now we have problem with cuba 7

can we have hope for support?

As a feature it would be nice to be able to add TAGS to files. Perhaps with the TokenList as the control for this.

Tags would help with searching and grouping.

It should be possible to display the Table of the Attachments within an Edit Screen. The attachments should be filtered for the currently selected Entity instance.
