Oracle APEX: IG error: Uncaught TypeError: Cannot read property 'outerHeight' of null

By -

I have an interactive grid on my page and I need to programmatically change the report from default to a named report. I am using the following javascript code to get report ID by report name and then change the report on my grid:

 try {
    v_array.forEach(function(element) {
        if (element.name == v_report_name) { 
            v_value = element.id; 
            throw BreakException; 
        }
    });
} catch (e) {
    if (e !== BreakException) throw e;
}

 apex.region("MY_IG").call("getActions").set("change-report", v_value);

The report gets changed yet there is an error on the page:

Uncaught TypeError: Cannot read property 'outerHeight' of null

If I comment out this line, error disappears:

     apex.region("MY_IG").call("getActions").set("change-report", v_value);

Can't figure out what is going on. This started happening right after the upgrade

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
