Hi, bellow an example how you can append new item into your surveyDoc array and the rich text field will update: a!localVariables(
 local!languageData:{survey:"some language"},
 local!surveyDoc:{appianDocumentId:101457},
 a!formLayout(
 label:"Dummy",
 contents:{
 a!richTextDisplayField(
 label: "",
 labelPosition: "COLLAPSED",
 value: {
 a!richTextItem(
 text: { index(local!languageData, "survey", {}) },
 style: "STRONG"
 ),
 " : ",
 if(
 count(local!surveyDoc) > 0,
 a!forEach(
 items: local!surveyDoc,
 expression: {
 a!richTextItem(
 text: document(
 tointeger(fv!item.appianDocumentId),
 "name"
 ) & char(13),
 link: if(
 rule!APN_isBlank(fv!item),
 null,
 if(
 true,
 a!startProcessLink(
 processModel: cons!PROCESS_MODEL,
 processParameters: {
 documentId: fv!item.documentId,
 appiandocid:fv!item.appianDocumentId
 }
 ),
 a!documentDownloadLink(
 label: document(tointeger(fv!item.appianDocumentId),"name"),
 document: fv!item.appianDocumentId
 )
 )
 )
 )
 }
 ),
 a!richTextItem(text: "Not Available")
 )
 }
 ),
 a!buttonLayout(
 secondaryButtons: {
 a!buttonWidget(
 label:"Update survey doc array",
 value:null,
 saveInto:a!save(
 local!surveyDoc,
 fn!append(
 {local!surveyDoc},
 {appianDocumentId:119534}
 )
 )
 )
 }
 )
 }
 )
)

I think the issue is that you need to pull something back from the process after you start it. You currently don't have any way of forcing the local!surveyDoc to refresh after the process completes (and I assume the process is generating a document that you wish to query?) 
 I'd suggest adding an "onSuccess" parameter to your start process above that saves the result of the process into another variable. Then, your local!surveyDoc can also check that variable to determine if it needs to refresh using a!refreshVariable().
