Hello all!

I've encountered a problem with updates of an excluded field (0.90.2 Elasticsearch version). For example, I have the following mapping:  
"mappings" : {  
"my\_mapping" : {  
"\_source" : { "excludes" : ["ex\_prop"] },  
"properties" : {  
"ex\_prop" : { "type" : "string", "index" : "analyzed" }  
}  
}  
}

I add a document with keyword "start":  
curl -XPUT localhost:9200/my\_index/my\_mapping/1 -d '{  
"ex\_prop" : " start "  
}'

Then I update the document:  
curl -XPOST 'localhost:9200/my\_index/my\_mapping/1/\_update' -d '{  
"script" : "ctx.\_source.ex\_prop += param\_ex",  
"params" : {  
"param\_ex" : " update "  
}  
}'

Sometimes this update fails with an error:  
{"error":"ElasticSearchIllegalArgumentException[failed to execute script]; nested: PropertyAccessException[[Error: could not access: ex\_prop; in class: java.util.LinkedHashMap]\n[Near : {... ctx.\_source.ex\_prop+param\_ex ....}]\n ^\n[Line: 1, Column: 1]]; ","status":400}

If updating is OK, I search for two keywords: "start" and "update". Elasticsearch never finds any documents with the "start" keyword. "update" is sometimes found, sometimes isn't.

But everything works fine with 0.20.4-3 Elasticsearch version.

Is this a bug, or do I do something wrong?

Here is the script I used for tests: \<nabble\_a href="script.sh"\>script.sh\</nabble\_a\>

Any ideas? I think this problem is critical...
