For Zoho Services only:


I'm actually part of a bigger team at Ascent Business Solutions where we have support technicians and project consultants. Support is for smaller technical fixes but this can include developments, reports or integrations; depending on the size of the task. Projects are for more time-consuming developments such as revamps of the Zoho Suite of apps or on-site training. The advantage of a team is that if I am out-of-office for a day or so, there is always someone at Ascent Business Solutions who can deal with any queries/issues you may have.

Our support rates can be found and purchased at http://ascentbusiness.co.uk/zoho-support-2. A support bundle doesn't have an expiry date. So whether we can do what you want within the bundle and a year later need further support, if there are minutes left on the bundle then there is no additional charge.

Our project rates for bigger developments can be found at http://ascentbusiness.co.uk/crm-solutions/zoho-crm-packages-prices and will involve a dedicated project consultant along with developers who will hold your hand through the development process.

If you want help building a solution for one of the Zoho Apps in the Zoho Suite, contact us on 0121 293 8140 (UK) or by email at info@ascentbusiness.co.uk. You can also visit our website at http://ascentbusiness.co.uk.

I regularly build and specialize in 2-way API integrations for Xero, Shopify and eBay.

Zoho Deluge - Store and repopulate a multi lookup list in Creator

What?
A quick reminder on how I got a working snippet of code to store the entries in the lookup already selected, check against another table/form for valid options, repopulate the list with the selected item and filtering the options available for selection.

Why?
This was for a multi lookup with staff as the list entries. The lookup needed to filter against various forms such as Staff Rotas, Leave Requests, Qualifications and some others.

How?
The aim/objective is the following:
  1. Store what was already selected in the lookups
  2. Clear the lookups list
  3. Restore what was originally selected as selected.
  4. Repopulate with a filter list of options (not selected but available)
copyraw
// *************************************************************
// store already selected entries
//
if(!isnull(input.myLookup))
{
    // remember remember the 5th of november
    l_RememberLookup = List();
    if(input.myLookup.size()>0)
    {
        for each  v_SelectedLookup in input.myLookup
        {
            l_RememberLookup.add(v_SelectedLookup);
        }
    }
}
//
// clear lookup
clear myLookup;
//
// get list of all valid entries 
l_AllowedEntries = {};
for each  v_AllowedID in myForm[ID != 0]
{
    v_thisID = v_AllowedID.ID;
    l_AllowedEntries.add(v_thisID);
}
//
// restore item in lookup
input.myLookup = l_RememberLookup;
//
// repopulate lookup options (not selected items)
for each  r_EntryID in l_AllowedEntries
{
    input.myLookup:ui.add(r_EntryID);
}

  33.  { 
  34.      input.myLookup:ui.add(r_EntryID)
  35.  } 

Additional Note(s):
  • If removing elements, even if you are using Creator v5, use removeElement() and NOT remove() which got me stuck for a while. This is for error
    copyraw
    ...datatype {0} is not the same as list datatype {1}...
    1.  ...datatype {0} is not the same as list datatype {1}...
