I can confirm that they are blank BUT if you leave them blank and look at the values in the generated field they match the values set in the plugin - so it does work but there is a UI bug

Updated ticket to more accurately describe the issue.

@quy now i am mmore cconfiused. After setting the values in the plugin and leaving the values blank in the field the values from the plugin are used. See screenshots

from my perspective the only issue is that the First, Last and Step fields in the field defintion should say "from plugin or enter a value" and not be blank

It appears you have updated/saved the Fields - Integer plugin which makes it work. If you leave the plugin as it without updating and saving it, then it won't work until updated.

This screenshot shows the 1st integer with blank values and the 2nd integer with filled values.

Say i understand you now.i am not at my computer anymore but iirc you should to see if the plugin has default values stored in the dB. I suspect not and that is the issue. The install SQL can be updated to fix that if my guess is correct

The plugin has default values, but it seems you have to initialize/save it for it to be in effect.

Which means that the default values are not present in the database on install and are only in the XML. They should be in both

The database actually doesn't matter that much. The default values should be in the XML and in the code where the param is requested.

@bakual maybe you are right and the default values are missing in the code from where the param is requested - I dont know where to look for that. I can say for certain that it resolved by setting the default param in the sql on install - but if you say thats the wrong way then I will wait for your reply as my PR would be wrong

I had a look and the way the params are merged, we can't easily add the default values to the code. So your approach with the database looks indeed better and easier.

OK - I will work on a PR now then

Closed as we have a PR see #15403
