Im returing a table of rows from GQI to LCA. Currently i have static column names. But I want to make it dynamic. I have fetched the necessary column names from DOM, but i can only access it in the method GetNextPage() as i want DM service to fetch the column names. Below is the code,

public GQIPage GetNextPage(GetNextPageInputArgs args)
{
var rows = new List<GQIRow>();
var serviceList = GetElements();
_logger.Information("SERVICE LIST -- " + serviceList.Count);
foreach (var service in serviceList)
{
var templateInstance = _domHelper.DomInstances.ReadAll().Where(x => x.GetSectionField<string>(
Em_Resourcemanagement.Sections.Protocol.Id,
Em_Resourcemanagement.Sections.Protocol.Workflow_Name) == service.Name && x.GetSectionField<string>(Em_Resourcemanagement.Sections.Serviceparams.Id,
Em_Resourcemanagement.Sections.Serviceparams.Is_Resource_Console) == "True");
foreach (var instance in templateInstance)
{
_resources=GetPidsFromDom(instance);
}
_logger.Information("ServiceName - " + service.Name);
var childInfos = service.Children.ToList();
//my other logics

_logger.Information("ROWS Length -- " + rows.Count);
return new GQIPage(rows.ToArray());
}

public GQIColumn[] GetColumns()
{
var resourceColumns = _resources.Select(x => new GQIStringColumn(x.DisplayColName)).ToList();
resourceColumns.Insert(0, new GQIStringColumn("Service"));
resourceColumns.Insert(1, new GQIStringColumn("Element"));
return resourceColumns.ToArray();
}

Previously i have declared the column names in OnInit function itself. After changing my code like this im getting error in my LCA. based on the logs i can see GetNextPage is not reached. The method hierarchy is On init function, Argument processed, Get Columns - error is caught in Get columns function and _resources will be empty
