Use static value for formatter in xml

former_member842244 — Wed, 11 Aug 2021 06:21:01 GMT

I want to use a static value on xml, to use it in formatter. I found this comment on stackoverflow but this doesn't work for me.

I use the version 1.70, i see the feature is after 1.61 available.

My code:

{ parts: [
	{path: 'modelName>/processState'}, 
	{value: 'german'}
], formatter: '.translation'}

In my app i dont get any text.

EDIT:

You know the code above don't work.

If i change to this:

{ parts: [
	{path: 'modelName>/processState'}, 
	{path: 'modelName>/german'}
], formatter: '.translation'}

But in this solution i must set the property "german" to german in JS.

This is my formatter

translation: function(sKey, sLanguage){
	return this.text(sKey, sLanguage)
}

My OpenUI5 Version was 1.78.8

Does the formatter get called at all without the "value"? How does your formatter look like? What does the OpenUI5 Version / Distribution say when you press [Ctrl] + [Shift] + [Left Alt] + [P]?

We need more information. Please update the question accordingly.

Hi,

if you need to set the property to "german", why you don't use a constant in the formatter function and pass only sKey as parameter?

translation: function(sKey){
	return this.text(sKey, 'german')
}

It's a bug in UI5 which was reported last year and has been fixed since version 1.80. See the GitHub issue "CompositeBinding parts mixed with named models and StaticBindings incompatible when creating ManagedObject declaratively"

Until the app can run with a newer version, you can circumvent the bug with the following temporary solution:

{
  parts: [
    { path: 'modelName>/processState' },
    { value: 'german', model: 'modelName' }
  ],
  formatter: '.translation'
}

Simply add the model name from one of the parts to the value binding info.

You might get an error log in the console but that can be ignored. Better update the UI5 version ASAP and remove the above workaround since SAPUI5 1.78 is already "out of maintenance".

xtrnhfo One of the advantages of using "value" is to be able to re-use the formatter in other bindings but with different static values. The above issue is a bug in UI5.
