Question

Process Model

Hi,

I am new to Appian and trying to work on an Asset Management Application. 

I am getting these two errors while running my Request Asset Process Model.

1) Invalid Cast: Cannot cast from type 'AT_Request' to type 'Boolean' (Data Inputs). Where should I fix the problem? 

2) The image at index 1 in an image gallery component [label=“”] has an invalid value for “document”. “document” must not be null. I am having this issue with my image component in all interfaces. 

When I test the interface with rule!GetAssetbyID(), the error is fixed but having a problem when running the process model.  My rule input takes the value of integer for Image. Is that the problem? I tried todocument and other options in the forum but no luck so far. 

 

Hope I can be helped.

Thanks

    Hi,

    For issue 1, looks like casting problem, means you are passing a value of type CDT into Boolean.

    For issue 2 , you need to make sure ,you are not providing null values as document

    Can you show the code of image configuration?

    Hi,

    Thanks for your response. 

    I fixed the first problem. 

    The second one I fixed in the interface but having the problem when running the process model. 

    !formLayout(
    label: "REQUEST ASSET APPROVAL FORM",
    contents: {
    a!sectionLayout(
    contents: {
    a!columnsLayout(
    columns: {
    a!columnLayout(
    contents: {
    a!textField(
    label: "REQUESTED ASSET DETAILS",
    labelPosition: "ABOVE",
    saveInto: {},
    refreshAfter: "UNFOCUS",
    readOnly: true,
    validations: {}
    )
    }
    ),
    a!columnLayout(
    contents: {}
    )
    }
    ),
    a!imageField(
    label: "Image",
    labelPosition: "ABOVE",
    images: {
    a!documentImage(
    ri!assetinput['recordType![AT Asset Management.fields.image]
    )

    },


    size: "MEDIUM",
    isThumbnail: false,
    style: "STANDARD"

    Thanks
