Array size limited to 21

[imocsari]

We have an issue, using the plugin, as it has a limit of 21 adding values to the array. Once the limit reached, it does not allow to add more element into the array. Any idea, how can we change the size of the limit in the plugin?

Is this an issue with the custom fieldtypes module or with a keystone field?

It seems to have the issue with the custom fieldtypes. We can add a 21st item fine, this 21st item gets added to the array that all the other items are added to.
However, when we then add a 22nd item, this array for some reason turns into an object.
Because the array is now an object, it is failing validation (as its expecting an array) and it fails before it gets to the point at which the app saves the data.

The issue why it didn't save data into the database , because it somehow after 21 added item it changed the data from array to object and the database couldn't validate it. Changing the object back to an array sorted the issue.
