Flow doesn't read data from JSON Data source

Is this by design, feature lacking or bug?

<script is="dmx-flow" id="flow1" type="text/dmx-flow" autorun="autorun">{
  assign: {
    value: "{{translation.data.Send}}{{browser.userAgent}}",
    name: "title",
    output: true
  }
}</script>

You are having a timing issue.

The flow runs directly, while the JSON data source has to fetch its source, so its data comes in later. And by then your flow is already done.

I presume at least that you have the flow ran automatically.

If you really want to use the JSON data - then add the flow run method on the success event of the JSON data source - then you know for sure that data is loaded.

Thanks. I was trying to actually do that manually as I didn’t think of the JSON data source with SC events. But yeah. There it is :slight_smile:

I will try later. Pretty sure it will do the trick.

@george it worked like a charm. Now I just need to achieve this when the json is being loaded in a php SSI.

The json file is loaded and on success event I run an inline flow to set a global variable.

<dmx-json-datasource id="trans" is="dmx-serverconnect" dmx-bind:url="../../assets/locales/{{locale}}/{{appName}}.json" dmx-on:success="run({setGlobal:{key:'translation',value:'loaded'}})"></dmx-json-datasource>

Now it would be great to run a flow from any page when translation has value loaded.

For this I have created a variable that reads the global and runs when it’s updated.

<dmx-value id="var1" dmx-on:updated="flow1.run()" dmx-bind:value="{{translation}}"></dmx-value>

Is this the best approach? I don’t feel very comfortable having such poor control and just running when the variable is updated(with any value).

Would like to have something like when {{translation}} == loaded run the flow by following this approach or other.

Ideally it would be directly from the json success event, but as it’s contained in a SSI it won’t do the trick.
