Unable to get param value with the paths specified

Hi All,

With the below configuration, I am not able to get the path param in the GET request.

import "github.com/labstack/echo/v4"

e := echo.New()

e.POST("/attributes/group/:confirm", func(c echo.Context) error { return c.NoContent(http.StatusOK) })
e.PATCH("/attributes/group/:confirm", func(c echo.Context) error { return c.NoContent(http.StatusOK) })
e.POST("/attributes/groups/:activated", func(c echo.Context) error { return c.NoContent(http.StatusOK) })
e.GET("/attributes/group/:id", func(c echo.Context) error {
	param := c.Param("id")
	log.Println("the param is", param)
	return c.NoContent(http.StatusOK)
})
e.POST("/attributes/group/reorder", func(c echo.Context) error { return c.NoContent(http.StatusOK) })
e.DELETE("/attributes/group/:id", func(c echo.Context) error { return c.NoContent(http.StatusOK) })

The log print in the GET function handler prints the param blank.

Just to check if my understanding of the routes is wrong, I tested the same in gin, and it is working properly.

For now changed the path of the GET request slightly to overcome this issue, but could someone please explain why this doesn't work.

Thanks.

I think it's related to this issue 1306. It'll be changed to version 5, I guess.

The first added route will define the param's name for the rest of the related routes. If you print the params names c.ParamNames() in the route e.GET(/attributes/group/:id, you'll see that the name is confirm instead of id. Because e.POST("/attributes/group/:confirm" was defined first.

If you put the e.GET(/attributes/group/:id in the first place of all the routes, the param will be id for the rest of the related routes.

Thanks @arctouch-rafaelturnes. That was indeed the issue.

Closing it since there is an ongoing discussion for the same.

What version you are using? I think this is resolved in v4.8.0 with this PR #2209

HI @aldas, this project was created before and was using version 4.2.x. I updated now and checked in 4.9.1 and it is fixed and working as expected.

Thanks for the help.
