Selectable grid

Hi, I am trying build read only selectable grid.

a!localVariables(
local!businessModuleStatus: rule!CR_QE_getModuleStatusForBusiness(
cif_int: ri!cif_int,
moduleId_int: ri!moduleId_int
),
a!boxLayout(
label: index(
local!businessModuleStatus,
"workflowDesc_txt",
""
),
style: "ACCENT",
contents: {
a!gridLayout(
spacing: "DENSE",
headerCells: {
a!forEach(
items: cons!CR_MODULE_STATUS_GRID_FIELDS_FOR_BUSINESS,
expression: a!gridLayoutHeaderCell(
label: fv!item,
align: "LEFT"
)
)
},
columnConfigs: {
a!gridLayoutColumnConfig(
width: "DISTRIBUTE",
weight: 2
),
a!gridLayoutColumnConfig(
width: "DISTRIBUTE",
weight: 2
),
a!gridLayoutColumnConfig(
width: "DISTRIBUTE",
weight: 2
),
a!gridLayoutColumnConfig(
width: "DISTRIBUTE",
weight: 2
),
a!gridLayoutColumnConfig(
width: "DISTRIBUTE",
weight: 2
),
a!gridLayoutColumnConfig(
width: "DISTRIBUTE",
weight: 2
)
},
rows: {
a!forEach(
items: local!businessModuleStatus,
expression: a!gridRowLayout(
id: fv!item.inputRequestId1_int,
contents: {
a!textField(
value: fv!item.workflowDesc_txt,
readOnly: true(),
align: "LEFT"
),
a!textField(
value: rule!APN_FN_getDisplayName(
userId: fv!item.initiatedBy_txt
),
readOnly: true(),
align: "LEFT"
),
a!textField(
value: rule!CR_FN_DateTimeFormat(
input: fv!item.initiatedOn_dt
),
readOnly: true(),
align: "LEFT"
),
a!textField(
value: fv!item.moduleStatus_txt,
readOnly: true(),
align: "LEFT"
),
a!textField(
value: rule!APN_FN_getDisplayName(
userId: fv!item.approvedBy_txt
),
readOnly: true(),
align: "LEFT"
),
a!textField(
value: rule!CR_FN_DateTimeFormat(
input: fv!item.approvedOn_dt
),
readOnly: true(),
align: "LEFT"
)
}
)
)
},
selectable: true(),
selectionStyle: "ROW_HIGHLIGHT",
selectionValue: ri!inputSelectedId_int,
selectionSaveInto: {
a!save(
ri!inputSelectedId_int,
tointeger(
index(
reverse(
save!value
),
1,
null
)
)
),
a!save(
ri!systemSelectedId_int,
index(
local!businessModuleStatus,
"systemRequestId_int",
""
),

)
},
selectionRequired: true()
)
}
)
)

On selection of row one variable will get updated due to Id of a row, then if i retrieve value for second variable from localvariable. It is not updating for second variable if I select a new row.

Can someone suggest on this?
