How to change display type of an existing Text field to a Picklist

Question

I need to modify an existing Text Field in the Expense report page to a Picklist and associate values to that picklist. Is this possible through Personalization ? If not, can someone let me know how this can be achieved.
Thanks
Meera

Answer 1

We created an item instead of creating a region and extending it. But here we have one more problem. The item we added is getting displayed at Button Layout section
Where did you create it, you should choose the appropriate region's create item icon to add it. If think you added it in a wrong place.
And one more issue that we are facing is - we are getting an error (No current row for View (<ViewInstance>)). when we clicking the save or next button in that page. Please let us know how to update the existing controller and save the value in that picklist item to the database.
There are two issues here,
- you are trying to replace the messageTextInput with the poplits, so you should get the viewAttribute and viewUsage name associated with the textinput and provide that as part of the messageChoice definition.
- the picklist VO which is the datasource for the poplist is not included in the existing seeded AM since you didnot follow the steps I mentioned earlier to create the stacklayout and add it instead of adding it directly. Probably you are on a version earlier than CU2, in which case you need to follow the additional steps mentioned below.
While adding the poplist donot specify the picklist view definitions,
1. extend the controller on the page and write your controller
2. Call super first
3. get a handle to the root AM and create the viewobject dynamically by using the createViewObject API on the AM.
4. get a handle to the poplist in the controller, you need to do this first before creating the poplist in the personalization(otherwise the page might error out if you created the poplist first without the picklist view definition properties) and set the display, value attributes as well as the picklist view defintions based on the viewobject you created in step 3.
5. Use personalization and add your poplist
6. replace the old controller class with the new one.
You are done.
