Hi Anupama,

DataStreamError can be a result of a connection loss between the app and repository and as a result not all the changes are being transferred. Can you please specify what happens if you export the package from the dev-app and import it to the target app using standard package export\import?

Best regards,

Oscar

Oscar Dylan,

Yes, even when we do standard Package import, receiving the data stream error. Basically in two scenarios we are experiencing this:

1. While updating package from SourceTree 

2. While installing a plugin

Anupama,

Please provide us with the detailed step-by-step instruction on how can we reproduce the same issue in the local app and we will check it.

Best regards,

Oscar

 Oscar Dylan,

It is reproducible in two scenarios:

1. When we deploy and update package in a new instance/environment-
   1. we use Git and SourceTree for source control.  when we clone the repository and update the package, we get the attached error<StreamError.jpg>.
2. While installing any marketplace plugin in existing instance
   1. installation fails and in the error log the same error message is captured

Hi Malay, 

Lookups are usually looking like that.

You can add "isSimpleLookup" to the virtual lookup attribute to make it a drop-down ,  so it might be much convenient for you.

Example:

"YourLookup": {
    dataValueType: Terrasoft.DataValueType.LOOKUP,
    isSimpleLookup: true,
    referenceSchemaName: "Employee"
}

Hi Bogdan Lesyk,

Thank you for your response.

I was asking about the binding of object with this virtual lookup. As, this is not properly bind with any object, it is not showing any values.

I have also inserted the property referenceSchemaName: "Employee" but it still does not show any values.

Regards,

Malay

Malay,

If you don't see any values of your Lookup, you've probably added wrong name of the object your Lookup should referring to.

Please check out the example of how it should looks like:

https://community.creatio.com/articles/virtualcolumn-lookup-field

Also check out the code my test implementation:

 attributes: {

                "UsrTestLookup": {

                    "dataValueType": Terrasoft.DataValueType.LOOKUP,

                    "type": Terrasoft.ViewModelColumnType.VIRTUAL_COLUMN,

                    isLookup: true,

                    caption: "virtual street",

                    referenceSchemaName: "Employee",

          isSimpleLookup: true

                }

            },

diff: /**SCHEMA_DIFF*/[

      {

                    "operation": "insert",

                    "parentName": "ProfileContainer",

                    "propertyName": "items",

                    "name": "UsrTestLookup",

                    "values": {

                        bindTo: "UsrTestLookup",

                        "caption": {"bindTo": "Resources.Strings.UsrTestLookupCaption"},

                        layout: {column: 0, row: 8, colSpan: 12}

                    }

                },

As far as I choose

 "parentName": "ProfileContainer"

and

isSimpleLookup: true,

please check out the result of such implementation.

So on Contact page I've got my "some lookup test" which has it's values from "Employee" object which it refers to.

Also please note,  that Virtual Lookup columns most often exist to store intermediate values, that can be further used for data processing.

Hi Bogdan,



How to add filter to the virtual Lookups, I had followed the above method to add virtual lookup. And when I tried to add filter to that, its not filtering out the data.

I have attached my code for the reference,





After adding the filter I am able to see all the values in the Lookup.

Is there a way, to Filter the Lookup values in Virtual lookup column ?
