I think that the main confusion is a result of the current state being defined in so many places, including this post.
I see the most recent update at GitHub states; "Removed example and exporter-all since they were outdated." For the exact same logic, you should remove the Readme too. Relying on someone to find this post in addition to the GitHub project is unreasonable.
Although I would like to provide an example, clearly I can't get it working so I can't provide an example.
Does anyone else subscribed to this post have an example?
Wiznia, I appreciate the effort to provide this user extension, and that you don't have time right now. But, neither do the people who want to use the extension. For others, at the very least, please add a line in the Readme that states it is out of date.
I needed the csv/excel download feature and implemented as mentioned in the post. But I get error as mentioned below:
Uncaught TypeError: Cannot call method 'substring' of undefined.
When I expand this error (I am using chrome developer tool) I see several lines of messages basically function call mostly pointing to
7th line of ext-all.js except one line which points to my app js file where I have defined the grid.
Is it because I am using grouped column headers its not able to get the store columns correctly ?
