Weird bug with image resources

[davidstone]

I'm trying to dynamically build a path to the resource for a particular Media object.

I worked out that I could concatenate "appres://resources/" along with some other letters which, strung together, point to one or another image. It's fairly rudimentary - it could be "EL_GR", and I'm just using a bunch of conditions to decide which letters to use.

When I put my formula into a label it correctly displays the full path to a valid resource, eg "appres://resources/EL_GR" - perfect.

Even better, I can put that formula into the 'Image' property of my media object - and it works! ...IN the desktop builder.

Once I publish, running on web or mobile, the media object no longer displays the actual image.

So to check it was still the same path on web and mobile, I placed a label and set its text value to simply 'EL_GR', directly referencing the media asset. On the app, it then displays the same resource path, as expected. So I published again, and all of a sudden the image now displays!

So in a sense I have a workaround - I can concat all my resources into a Label value and hide the label, and then everything is good.

But there's surely something wrong there for me to have to do this?

Thanks for any insight!

Hi @davidstone

I think the best way to resolve this is to load the images into a collection with a unique column to identify them.

Then you can dynamically look up the image.

Please let me know if you need details on this, but loading the collection is basically:

ClearCollect(MyImages,
  {Id:1, MyImage: ImageNameX},
  {Id:2, MyImage: ImageNameY},
 etc. etc.)

Thanks.

How would I then reference the image I wanted to display?

You should use the following as the Image property of an image control

LookUp(MyImages, Id=YourParameter, MyImage)
