Sending data as application/JSON throws error

I want to send data over the body as application/json. This is my request:
But with that I only get:
The #FormParam is utilized when the content type of the request entity
is not application/x-www-form-urlencoded
My Code:
<cffunction name="createInstance" access="remote" returntype="any" produces="application/json" httpmethod="POST" restpath="/instances">
<cfargument name="customerId" required="true" restArgSource="form" type="string" default=""/>
<cfargument name="name" required="true" restArgSource="form" type="string" default=""/>
<cfargument name="datasource" required="false" restArgSource="form" type="string" default=""/>
<cfargument name="startDate" required="true" restArgSource="form" type="string" default=""/>
<cfargument name="expirationDate" required="false" restArgSource="form" type="string" default=""/>
<cfargument name="amount" required="true" restArgSource="form" type="numeric" default=-1/>
<cfreturn name>
</cffunction>
Usually the JSON handlers should be used as GET method. Can you try with httpmethod as GET and restArgSource as path.
<cffunction name="createInstance"
access="remote"
returntype="any"
produces="application/json"
httpmethod="GET"
restpath="/instances">
<cfargument name="customerId" required="true"
restArgSource="Path" type="numeric" />
If you still need the request as POST, can you please share the headers tab?

Adding custom properties in workflow task at "workflow I have started " page alfresco share

I need to add custom properties in task row at the "workflow I have started" page.By default one task bar/row contains properties such as due,description,type and started.How to customize to add our custom properties along/instead of these properties.
You can define new form in form configuration with id as workflow-details.Check share-workflow-form-config.xml for more details.Given below is the example of one form taken from the same file, which is defining properties of the page you mentioned.

How to make Multiple word search in SOLRJQuery

I am currently working with SolrJ API for our webapplication. We need to have multiple word search in the application. But I do not know how to do it.
Here is the code we have developed so far by searching on the web.
HttpSolrClient solr = new HttpSolrClient("http://localhost:8983/solr/Test");
SolrQuery query = new SolrQuery();
query.setQuery("product_name:Dell laptop*");
query.setFields("product_name");
query.setStart(0);
query.setRows(1000);
QueryResponse response = solr.query(query);
SolrDocumentList results = response.getResults();
for (int i = 0; i < results.size(); ++i) {
System.out.println(results.get(i));
}
But I am not getting any result output. Our Solr has a mongo DB merged into it with the help of admin console of apache Solr which is running at 8983 port.
Please help. I am new to apache SOLR.

What you are running into is mentioned in Lucene's JavaDoc. Why Lucene? Solr's query syntax is a superset of Lucene's. As mentioned there
Note: The field is only valid for the term that it directly precedes, so the query
title:Do it right
Will only find "Do" in the title field. It will find "it" and "right" in the default field (in this case the text field).
In your case only Dell is directed to the field product_name, the rest is directed to the default search field defined in your configuration.
What you want to use to get around this is called Field Grouping. Therefore you need to surround the words that shall go to one field with round brackets, like this
SolrQuery query = new SolrQuery();
query.setQuery("product_name:(Dell laptop*)"); // surround the words with ( ... )
query.setFields("product_name");
query.setStart(0);
query.setRows(1000);

QuickFIX/n and FXALL

I am trying to send a MarketDataRequest to FXAll FIX Server using FIX 4.3 standard. Looking at the documentation the response from the server should be as follow
<message name="MarketDataIncrementalRefresh" msgtype="X" msgcat="app">
<field name="MDReqID" required="N" />
<group name="NoMDEntries" required="Y">
<field name="MDUpdateAction" required="Y" />
<field name="DeleteReason" required="N" />
<field name="MDEntryType" required="N" />
<field name="MDEntryID" required="N" />
<field name="MDEntryRefID" required="N" />
<component name="Instrument" required="N" />
<field name="FinancialStatus" required="N" />
<field name="CorporateAction" required="N" />
... omissis ...
</group>
</message>
but in the FXAll API Documentation field 55 (Instrument o Symbol) is expected just after the field MDReqID like it should be on the standard MarketDataSnapshotFullRefresh message
<message name="MarketDataSnapshotFullRefresh" msgtype="W" msgcat="app">
<field name="MDReqID" required="N" />
<component name="Instrument" required="Y" />
... omissis ...
</message>
Of course QuickFix/n engine is trapping a message MarketDataIncrementalRefresh with the field msgtype="X" and then I always have a TagNotDefinedForMessage error. How to solve this problem?
Thank in advance.
We modified our FIX43.xml file to FIX43_FXALL.xml and specific in the quickfix config file that we wanted to use that specific data dictionary (ie we used the direct path the file).
The modification looked like this:

entity framework - inheritance design

Using .Net 4 with EF 1.0: I have a table per type inheritance database structure and edmx (see diagram and cutdown edmx at the end of the post. The edmx is created through a code generator). I've just included one subtype for this post but there are many!
All of our entity framework queries are also dynamically generated. So at the moment when I try to retrieve a product (which may or may not be a book) I have the following ESQL query being generated.
SELECT VALUE [tb_product] FROM [tb_product] as [tb_product] WHERE (([tb_product].[Id] = #p0))
If the object I've requested is a book, the object I'm getting returned to me is of type 'tb_product'. I can't seem to cast or otherwise access the 'book' information from this tb_product object.
How can I modify the query, edmx or some other component so that when I query the base type I can also access all relevant subtype information without a second database trip. Can I?
