0048884: Full Refresh generated in deploy without changes or model insertion in webPOS

DescriptionIf a model has changed, a frontend hash is stored from the list of properties of which the model is a part.
In 20Q3, in the case of TaxCategory, in (the Taxes query), this was done:

  public List<String> getMasterDataModelProperties() {
    return getPropertiesFrom(;

In this function, the properties of the TaxCategory entity are returned. This includes the list-like properties that are generated for the "child" models that are marked with IS_CHILD_PROPERTY_IN_PARENT="Y".

When changes are added that are not related to webPOS models, but are children to models that use webPOS, it changes the hash and generates a full refresh on the terminals.

This can happen with various models: discount, taxcategory, taxcategorybom, productservicelinked and more.
Steps To Reproduce- Open the terminal.
- Create a new child table of TaxCategory.
- Deploy.
- A full refresh will be generated in the terminal
Proposed SolutionChange the following function to ignore child properties

protected static List<String> getPropertiesFrom(Class<?> entityClass) {

Class MasterDataProcessHQLQuery

Hello Sofia,

I just checked and what you mentioned does not match the code in 20Q3. This [1] is the implementation of TaxRate.getMasterDataModelProperties in 20Q3, and it just lists the properties defined in its ModelExtension. No list properties should be included unless a ModelExtension explicitely includes it.

Where did you get the implementation pasted in the description?

Hi Augusto,

In fact, there is a mistake in the issue reported, the problem didn't happen with a List property in TaxRate but in TaxCategory instead: [^]

This model (and several others) use a utility method in MasterDataProcessHQLQuery (getPropertiesFrom(Class<?> entityClass). This method returns all the properties of the given entity class, including List properties.

This caused an unintended full refresh in a customer yesterday. We can discuss quickly together if some detail is still missing.

Fixes ISSUE-48884: Full Refresh generated in deploy without changes or model insertion in webPOS
After doing changes in models that are related to webPOS modules, it changes the hash and generates a full refresh on the terminals.
To fix this,we add a filter in this function getPropertiesFrom in MasterDataProcessHQLQuery to not get list properties that are represented as OneToMany relation.
