[Solved] Raw data with Everlive DataSource

[jmillar]

Hi there;

I'm trying to get at the raw data returned by an Everlive datasource (specifically, so that I can update values in a radial gauge), but when I look at the <datasource>.data.length property it always returns 0 and there doesn't seem to be any contents.  Am I doing something wrong?  What type of data should I expect .data() to return?

Thanks,
Jason

Hello Jason,

Do you call the dataSource fetch() method in order to read the data from the Everlive back services? If you do not fetch() the data then the length will always be 0. Please check the following example that shows a non-working/working example

Thanks Kiril;

I was calling read() and not fetch(), but basically the same thing.  Since I'm new to the framework, I think what was tripping me up was not appreciating the fact that the Everlive calls are asynchronous....my handler was immediately after the read() call instead of being provided as a callback.  Once I switch to a callback, everything worked fine.

Thanks,
Jason

Hello Jason,

And this is why it works with fetch() method that provides the callback. I am happy to hear that you got it working, in case you have any further questions, please do not hesitate to contact us.
