Thanks @Mike for your information.

But I believe suggesting answers will help people in future who come up here with such basic doubts.

Discussions with suggested answer tag can help people to search discussions and solutions quickly

Just as an FYI, it's probably not very useful to post new replies on these old "zombie" threads (those over 1 year old, or even over a few months old in most cases), as the issues are most likely long since resolved or irrelevant.

Rewrite the code so that you are not executing the query when value provided to filter field is empty.

By any chance, is it possible for you to attach the screenshot of your CDT structure and the sample response data, because i suspect on it's field name as well as it's value.

If you can share these details, will help the practitioner to identify the root cause and provide you the resolution to overcome this issue.

Please supply us with some more details.

First, it would help to see the structure of the CDT for ri!businessDivison.

Second, I would like you to please run the following modified query and paste the output here:

a!queryEntity(
  entity: cons!LCW_BUSINESS_UNIT_ENTITY,
  query: a!query(
    pagingInfo: a!pagingInfo(
      startIndex: 1,
      batchSize: 1
    )
  )
)

I tried to made a filter with a!pickerFieldCustom component.

The value that I get from this component, I want to put it as a Filter Value for the a!queryEntity and made the filter directly to the a!gridField, but this error appear: Cannot apply a filter with a blank field name

In query Filter in filed mention actual filed like

a!queryFilter(
field: "businessDivision",
operator: "=",
value: ri!businessDivision.id)
)

your filed name in cdt

a!queryEntity(
entity: cons!LCW_BUSINESS_UNIT_ENTITY,
query: a!query(
filter: if(
rule!APN_isEmpty(
ri!businessDivision.id
),
null,
a!queryFilter(
field: "businessDivision",
operator: "=",
value: ri!businessDivision.id
)
),
pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: - 1,
sort: a!sortInfo(
field: "order",
ascending: true
)
)
),
fetchTotalCount: true
)

Hi Vinay.

I got the same error above this conversations, and I try to implement your code but It doesn't work.

I tried to filter a field from a datagrid using this similar code.

Hi,

The error occur because the parameter ri!businessDivision.id is null.
Your filter condition is incorrectly placed, try this

if(
rule!APN_isEmpty(ri!businessDivision.id),
{},
<query entity>
)

hi Ashvin, thanks for the reply. My task is to create cascading dropdowns. for that i have created foreign key relationships in the CDTs. so for the second dropdown to pop up, i try to take the selected choice of the first dropdown. Hence i use businessDivision.id. basically i have like businessDivision-->businessUnit-->businessLine.

Not sure how your CDT is set up, but my guess is that the field parameter should be "id" instead of "businessDivision.id" in your query filter.
