Java Heap Space error in Designer on Dataset script transform

Ignition

Hi all,

I'm using a custom function on a table to set the column properties, then a script transform to get the values and fine tune any additional column props.

The dataset I am working with has almost 1900 rows, 20 columns. This is the link to the thread for all the scripts: Cell value change...

The table's pager is enabled.

The reason I would like to use this scripting is to customize the table with color styling and using one embedded view in one column, so that when a value is changed, the row or cell will change color and indicate that it has been edited.

I get the Java Heap Space error on this table with almost 1900 rows. So, aside from changing the heap memory in the config file, are there other things I should or could do to prevent this?

Thanks.

The out of memory error here is the heap space of the designer, not the Ignition gateway process (configured via the configuration file).

The Designer's heap memory can be configured in gateway settings or locally overridden in the launcher settings.

Gotcha. Thanks Paul.
