HistoricPlanItemInstanceQuery missing option to query for variables

The HistoricPlanItemInstanceQuery is missing methods to query for variables, such as variableValueEqualsIgnoreCase(name: String, value: String). Other historic queries have these methods implemented (see HistoricCaseInstanceQuery, HistoricTaskInstanceQuery, HistoricProcessInstanceQuery).

Also, the PlanItemInstanceQuery (non-historic) has functionality to query for variables. All of these seems to use the AbstractVariableQueryImpl, except for the HistoricPlanItemInstanceQuery (perhaps for a reason).

Will it be added in the future, or is there some workaround to add this functionality to an existing query?

Hey @mennotol,

There is no particular reason why those methods are missing. We haven’t had a request to have these methods in that query. If this is something that you are interested in you can provide a PR that we can look into it.
