Android Question WriteMap/ReadMap with List as value

[msali]

Hi,
I have created a Map with a string as Key and List in Values - No issue.

thisLst.InsertAt(typMapFld.Duration, 0)
thisLst.InsertAt(typMapFld.SeqLength, 1)
thisLst.InsertAt(typMapFld.Attempts, 2)
thisLst.InsertAt(typMapFld.isCurrentStage, 3)
thisLst.InsertAt(typMapFld.isCompleted, 4)
'
thisMap.Put(key, thisLst)

Then I save it using WriteMap

File.WriteMap(SS_FilePath, "stages", thisMap)

After Saving it I try to read it with ReadMap and try reading the list stored in value

mapStages= File.ReadMap(SS_FilePath, "stages")
thislst= mapStages.Get(key)

I am unable to read the list properly.

Where am I going wrong. Is this type of structure not allowed?

Thanks in adv.

Cheers

Check the documentation of File.WriteMap

https://www.b4x.com/android/forum/pages/results/?query=File.WriteMap

File. WriteMap (Dir As String, FileName As String, Map As Map)
Creates a new file and writes the given map. Each key value pair is written as a single line.
All values are converted to strings.

You should use Randomaccessfile.writeb4xobject and Randomaccessfile.readb4xobject to read the map back.

Too good... I created a simple test project and it worked perfectly well.

Now tomorrow I will embed it in my main project.

Just Perfect.

Thanks a lot.
