LookupService Encoding Error

Posted on by Community Member

After migrating a previous CRM install to CRM 2016 there were a number of issues to be fixed. One of the issues involved a form with two dropdown boxes,

1. Selecting a value from the top dropdown box "Employers" would run a javascript function that returned a view with all the employees for that employer

2. The view would be used to populate the second ("Employees") dropdown box

There was an error that occurred anytime the Employer name contained an ampersand so I modified the javascript to encode the ampersand and everything worked fine after that, until I noticed that after creating the record, if you re-entered the same record you just created and then tried to click on the little magnifying glass icon associated with the "Employee" there would be a number of errors thrown - again, only if the "Employer" dropdown contained an employer name with an ampersand  - but the it doesn't appear that the same javascript is being executed.

If I run fiddler when attempting to do this, I appear to get an error associated with the ampersand when making a call to LookupService.asmx. The error says "An error occurred while parsing EntityName..."

System.Xml.XmlException: An error occurred while parsing EntityName. Line 8, position 74.

   at System.Xml.XmlTextReaderImpl.Throw(String res, Int32 lineNo, Int32 linePos)

   at System.Xml.XmlTextReaderImpl.HandleEntityReference(Boolean isInAttributeValue, EntityExpandType expandType, Int32& charRefEndPos)

   at System.Xml.XmlTextReaderImpl.ParseAttributeValueSlow(Int32 curPos, Char quoteChar, NodeData attr)

   at System.Xml.XmlTextReaderImpl.ParseAttributes()

   at System.Xml.XmlTextReaderImpl.ParseElement()

   at System.Xml.XmlTextReaderImpl.ParseElementContent()

   at System.Xml.XmlLoader.LoadNode(Boolean skipOverWhitespace)

   at System.Xml.XmlLoader.LoadDocSequence(XmlDocument parentDoc)

My question is - how do I find the code that is calling the LookupService? I do not see anything directly associated with clicking on the magnifying glass icon associated with the dropdown. Is there some way to view (or step through (F11)) the call to the LookupService?

Thanks.

    Hi

    Is this with all the browser?

    Did you clear the cache?

    No, it won't be a cache issue.

    When creating a new record, the "Employers" dropdown is associated with a javascript file that executes the query to populate the "Employees" dropdown. This allows me to escape the ampersand before the query for "Employees" is submitted.

    When attempting to edit an existing record, the "Employer" and "Employee" dropdowns will display the values that were selected when the record was created. However, if I want to change the "Employee" value I click on the dropdown's "search" icon and it seems that this causes a query to execute that will populate the control with all the employees associated with the current employer, but the execution of this query does NOT go through the same javascript functions that are used when the record is created so I do not have the opportunity to escape the ampersand.

    My question is, how do I identify the code that is being executed to make this query? I can only imagine that there is a relationship by configuration or convention that links the control to the query but I do not know enough about CRM to find that code. If I can find the code, I can escape the ampersand BEFORE the query is made (just as I did in the previous javascript file) and everything should be fine.

    Thanks
