Two Independent Databands; Mirrors data if one is empty

Post by Andreas Koetzle »

Hello special team,

if got two databands with two independent datasource (JSON).
All works well if both datasources has data.
If one of the two is empty, the other one is mirroring the data from the other datasource.

I send you my testversion and two json files. If you empty one of them and preview the data, you will see me problem.

What i am doing wrong.....

Thank you.

Hello,
If one of the two is empty, the other one is mirroring the data from the other datasource.
In this case, it is the specifics of working with data. If you register data with a name different from the one in the dictionary, it can lead to problems.
In this case, if only one table is registered in the DataStore, it is taken regardless of the name.

Thank you.

Hello,

If several data sources are created in the dictionary, but only one table is registered(data file added to resource, etc.) in the data source,
there will be ambiguity, because this table will be used in both data sources. This is done on purpose to avoid problems when registering data with a different name than the one in the dictionary.

In your case, when you remove one of the json for the data source, the remaining json in the resources will be used for the two data sources.

Thank you.

I thought i have two datasources (BT and PS) and two different tables (root and root2). Only the datafieldnames are the same.

I do not agree with you about "removing" a json file. I only empty one of them. I real could it be possible, that there is now data for one of the datasoources.

i am to be at a loss....

Thank you for your effort.
Best regards

Hello,

This would be the same situation where you have no data in one of the json (or you remove one of the json from the resources).
The data from the second json will be used for both tables.

Thank you.
