FYI: When <table-plus> generates a "can't convert String into Integer" error

[Tim Griffin]

I'm just posting some info here that might be helpful to others using the <table-plus> tag who happen to get a "can't convert String into Integer" error.

In my Hobo 1.3 case, I ran into an issue displaying a <table-plus> using a manually-created array of OpenStruct records (pulled from a legacy database table) that did not include <xxx-heading> tags. Hobo continually reported a "can't convert String into Integer" error when processing the <table-plus> tag.

In a model file, I was using this approach: def get_documents #Setup a new array to hold the document records table = Array.new documents = Document.find_by_sql('SELECT dbo.LLAttrBlobData.ID AS [doc_id],... ... ') r = 0 documents.each do |doc| table[r] = OpenStruct.new(:doc_id => doc.doc_id, :filing_date => doc.filing_date, :filing => doc.filing) r = r + 1 end return table end And in the view:

<table-plus:get_documents fields="doc_id,filing_date,filing"> </table-plus:get_documents>

Hobo generated "can't convert String into Integer" Bryan indicated that "with many versions of Hobo, you need to specify the headings:" So, I added heading tags to the <table-plus> call as follows:

<table-plus:get_documents fields="doc_id,filing_date,filing"> <doc-id-heading:>ID</doc-id-heading:> <filing-date-heading:>filing date</filing-date-heading:> <filing-heading:></filing-heading:> </table-plus:get_documents>

which made <table-plus> work as expected. Bryan also notes: "it broke in 1.3 because of the internationalization changes. It's something we need to add to the test suite."

This issue has been reported as Hobo Ticket 991. Tim
