Why does my Sharepoint WebPart deploy (nominally), but is still not available for adding to a page/form? -


i've created , "deployed" latest web part (visual studio grins ear-to-ear, , tells me, "deploy succeeded").

but when go our sharepoint site, , "sandbox" page, , edit it, not see webpart. elements file shows, should available "financial affairs forms" category:

<?xml version="1.0" encoding="utf-8"?> <elements xmlns="http://schemas.microsoft.com/sharepoint/" >   <module name="posttravelexpensewebpart" list="113" url="_catalogs/wp">       <file path="posttravelexpensewebpart\posttravelexpensewebpart.webpart" url="posttravelexpensewebpart.webpart" type="ghostableinlibrary" >       <property name="group" value="financial affairs forms" />     </file> </module> </elements>

however, category devoid of "posttravelexpensewebpart" expect (or @ least hope) see there:

enter image description here

what might omitting?

update

i went far to, while in edit mode on web page, expand "upload web part" section below "categories" after selecting 1 of "add web part" links. didn't know upload (when browsing file, file dialog doesn't clue in on file extension expects), i, on flayer, tried uploading posttravelexpense.ascx

it accepted without balking, not see anywhere (nor know why *.ascx file enough, again, file expect?) doesn't allow me upload entire project folder.

update 2

in response comment below, note project's assembly deployment target" property is set globalassembycache

by comparing working project one, able deploy without "a web part or web form control on page cannot displayed or imported. type not found or not registered safe." add-time error msg.

what had check every place in working project primary namespace referenced, , make sure corresponding namespace in previously-unworking project referenced in same places

this required not changing of files visible in visual studio's solution explorer treeview, 2 able load editor searching strings contained, specifically:

the ***.spdata** file, loaded searching "safecontrol" **assembly.info**, loaded searching "assemblytitle"

that sure lot of hand-wringing , head-banging , pitiful whin[g]ing 1 think automatically taken care of ide - when namespace changes, make necessary changes, or at least notify coder , offer so! or, barring that, at least give him better clue "a web part or web form control on page cannot displayed or imported. type not found or not registered safe." when webpart plopped onto page proves unploppable.

go - Idiomatic way to handle template errors in golang -

say have html/template following: <html> <body> <p>{{somefunc .somedata}}</p> </body> and somefunc returns error. there idiomatic way deal this? if write directly responsewriter , status code 200 has been written before encounter error. var tmpl *template.template func handler(w http.responsewriter, r *http.request) { err := tmpl.execute(w, data) // "<html><body><p>" has been written... // err? } preferably return status code 400 or such, can't see way if use template.execute directly on responsewriter . there i'm missing? since template engine generates output on-the-fly, parts of template preceding somefunc call sent output. , if output not buffered, (along http 200 status) may sent. you can't that. what can perform check before call template.execute() . in trivial case should enough call somefunc() , check return value. if choose path , return value of somefunc() c...
