Issue with variables on a LCA

Ana Pinho [SLC] [DevOps Advocate]1.33K 2nd May 2025 1 Comment

Hi Dojo,

We're working with an LCA that includes several components: a line & area chart, a grid, tables, and more.

When the app is launched, users are expected to click on a Config button, which opens an IAS. In this dialog, users can configure three different elements that are then used to filter the components mentioned above. (By passing them through output script param)

Initially, these elements were stored as variables in the user session, which worked fine—until the app was reloaded. Since session variables are not persisted, they get lost upon reload, which is not acceptable for our use case.

As a second approach, we decided to store the configured elements in a DOM instance and replace the session variables (previously of type Element) with Object Manager instance references.

Currently, we’re testing with only one of the three elements. For simplicity, I stored the element ID in the name of the DOM instance and tried using it to filter the components and queries.

This approach partially worked: it applies correctly for most components, but the Line & Area chart doesn't support filtering using the DOM object (?), so it's not functioning as expected there.

I'm getting out of ideas on how to do this.

Any suggestions?

Ana

Hi Ana,
Just brainstorming here. Is it not an option to use memory files as persistent storage?

Hi Ana,

The Line & Area chart only supports parameter data and queries. DOM instances can not be added as a data/filter source since the component has no idea what to do with that. The DOM instance can have a lot of data, all with different types, which makes it unpractical to figure out what data you expect to see on the chart.

For this use case, you would need a way to start from the DOM instance and transform it, based on the data inside, to an element or parameter. This sounds like a good feature for the Flows. I have created a task on our backlog to look further into this.

Hi Wout!

Thank you for your reply. Any easy way of transforming the DOM instance?

Wout Mahieu [SLC] [DevOps Catalyst] commented 5th May 2025

There currently is no way to transform one data type to another. What you could do is use the DOM instance as an input argument for an query with an ad hoc source. This query can then use the information inside the DOM instance to return points for the line chart
