EventFilters: Access to an existing filter to add more forms by eventtype

Question

We have a system in which we previously added the EventFilters et_CLICK and et_FORM_CLOSE, later when in the addon we need to add the filters if we need to filter any extra form for those events it raises an error: "Filter already exists" so we had to acces to the existing filter in order to add the other forms typeex, the problem is it only works if you use indexes...not eventtype or strings...Its possible to access to an existing eventfilter by eventype or string or name or so...?
Example:
In a centraliced function:
EventFilters oFilters = new EventFilters();
oFilter = oFilters.Add(BoEventTypes.et_CLICK);
oFilter.AddEx("OurGenericFormX");
SBO_Application.SetFilter(oFilters);
In addon inicialisation:
EventFilters oFilters = ConsSAP.SBO_Application.GetFilter();
oFilter = oFilters.Add(BoEventTypes.et_CLICK); //this logically throws an error
oFilter = oFilters.Item(BoEventTypes.et_CLICK); //this would be the desired way but throws an error :S
oFilter = oFilters.Item("et_CLICK"); //throws an error too :S
oFilter = oFilters.Item(0); //works but its dangerous as it seems SAP reorders the EventFilters alphabetically (instead of the order you added them)
oFilter.AddEx("AddonForm1");
We know we could make a loop and get the correct eventfilter by oFilter.EventType but this doesnt seem performancewise
Anyone knows how to access to an existing eventfilter by eventype or string or name or so...?

Hi,
I don't know why you are doing this so complicated, but event types are not reordered, it is an enum.
You can find it in SDK Help, just search for BoEventTypes.

edit: just in addition: you are right, the collection is based on an index starting with 0. You could read out the collection with filters.GetAsXML, then you can see on which index which enum value / event type is listed.
