Error in actionAjaxUpload

[BrunoAl25]

When i add an image for upload gives the error "Trying to get property of non-object" in the line $image = $this->behavior->addImage($fileName)

I check it out in FireBug and i can see all the properties from the image , but in the addImage simples crash.

Looks weird... Likely you have something wrong in configuration... - can you show your code related to gallery manager?

[BrunoAl25]

I created a simple table Call PRODUCT

CREATE TABLE IF NOT EXISTS tbl_product (
  id serial,
  product varchar(125) NOT NULL,  
  gallery_id int NOT NULL,
  file_name varchar(128) NOT NULL, 
  CONSTRAINT tbl_product_pkey PRIMARY KEY (id),    
  CONSTRAINT tbl_product_gallery_image_id FOREIGN KEY (gallery_id) REFERENCES tbl_gallery_image(id)  
);

After that ran the migration to create the table gallery_image.

This is the files:

Looks like I found a bug: use zxbodya\yii2\galleryManager\galleryBehavior;

galleryBehavior should be GalleryBehavior
