Multiple times update doc crash :com.couchbase.lite.CouchbaseLiteException: Conflicts not allowed and there is already an existing doc with id: 129047 about todolite-android

[liufsd]

So i update my code:
create:

        mDocument = database.getDocument(getDocumentUniqueId());
            UnsavedRevision revision = mDocument.createRevision();
            revision.setUserProperties(mProperties);
            revision.save();

and update:

  try {
                Document document = DBController.getInstance().getCouchDatabase().getDocument(reviewInfoDocument.getDocumentUniqueId());
                Map<String, Object> baseMaps = new HashMap<String, Object>();
                baseMaps.putAll(document.getProperties());
                boolean change = false;
                for (Map.Entry<String, Object> entry : reviewInfoDocument.getProperties().entrySet()) {
                    if (baseMaps.containsKey(entry.getKey())) {
                        if (!baseMaps.get(entry.getKey()).equals(entry.getValue())) {
                            change = true;
                            baseMaps.put(entry.getKey(), entry.getValue());
                        }
                    }else{
                        change = true;
                        baseMaps.put(entry.getKey(), entry.getValue());
                    }
                }
                if (change) {
                    document.putProperties(baseMaps);
                    Log.e(LOG_TAG, "Updated Document details :: " + document.getId() + "---" + document.getCurrentRevisionId());
                }
            } catch (CouchbaseLiteException e) {
                e.printStackTrace();
            }

But crash again:

com.couchbase.lite.CouchbaseLiteException: Conflicts not allowed and there is already an existing doc with id: 129049

#crash 'com.couchbase.lite.CouchbaseLiteException: Conflicts not allowed and there is already an existing doc with id: 129051'

What's wrong ???

[snej]

The properties you save to a document have to include a _rev property containing the document's current revision ID. This is to avoid overwriting a newer revision you didn't know about. Please read the docs to see the correct way to update a document. Basically you get the existing properties, modify them (preserving _rev) and save those as the new properties.

[liufsd]

First thanks.but I think you have not got my word. My log show rev,it's doc private properties,I just print it on my logcat.
(Log.e(LOG_TAG, "Updated Document details :: " + document.getId() + "---" + document.getCurrentRevisionId());)

I have not add rev. It's automatically create by couch base.My doc just have "uuid,name,exp." properties! And as I know some times update success.but crash by first update often. I Guss maybe it's cache problems? I have test sample project,and update more than 100 times,it's succes.but why my project can't update?
My question is how to update a doc to fix 409 errors!
Thanks!

oh, i think, i have use doc instance in my memory cache,and then update it multiple times ,may be it's the key ?

If you reuse the same properties dictionary, yes, you'll get conflict errors. The dictionary will still have the old _rev value, not the new one that was assigned to the latest revision, so the next time you re-use it you'll get the error.

oh.i see.i try to fix it .

         // Create document if required
        if (mDocument == null) {
            mDocument = database.getDocument(getDocumentUniqueId());
            UnsavedRevision revision = mDocument.createRevision();
            revision.setUserProperties(mProperties);
            revision.save();
            Log.e("ReciteSupportController", "create doc here :: " + mDocument.getId() + "---" + mDocument.getCurrentRevisionId());
        }else {
            //updte document if required
            Map<String, Object> baseMaps = new HashMap<String, Object>();
            baseMaps.putAll(mDocument.getProperties());
            boolean hasChange = false;
            for (Map.Entry<String, Object> entry : mProperties.entrySet()) {
                if (baseMaps.containsKey(entry.getKey())) {
                    if (!baseMaps.get(entry.getKey()).equals(entry.getValue())) {
                        baseMaps.put(entry.getKey(), entry.getValue());
                        hasChange = true;
                    }
                }else{
                    baseMaps.put(entry.getKey(), entry.getValue());
                    hasChange = true;
                }
            }
            if (hasChange) {
                //update old doc if required
                //(note:com.couchbase.lite.CouchbaseLiteException: Conflicts not allowed and there is already an existing doc with id: 129051)
                mDocument.putProperties(baseMaps);
                //and then reload doc to fix Conflicts
                mDocument = database.getDocument(getDocumentUniqueId());
                if (mDocument != null) {
                    mProperties = new HashMap<String, Object>();
                    mProperties.putAll(mDocument.getProperties());
                    Log.e("ReciteSupportController", "doc change update  :: " + mDocument.getId() + "---" + mDocument.getCurrentRevisionId());
                }
            }
        }

Am i right ???
Thanks.
