Slider update problem specific to PR #125

[elbfox]

In the CombinedPreferenceOutput branch (see #125), when I click "Update" on any individual dam page after moving slider bar settings, the app shuts down. There are no error codes so I am not sure what is happening. I put a note there about the error, too.

I'm hoping it's just an indentation problem that's confusing the button --> output functionality.

[sythel]

haven't experienced this. indentation won't cause syntax problems in this language as far as i know

[elbfox]

i know only enough Shiny to get myself into trouble. I'm getting an error when I update any dam criteria sliders.

EDIT: Error code indicates that server.R can't find/use WestEnf_DataMatrix or that it doesn't exist

[elbfox]

Could it be because I rearranged the multi-dam output tabs to show up before the single dam output tabs in the ui.R script?

[elbfox]

This is what is happening before it kicks me out:

error is server.R line 630 WestEnf_DataMatrix variable isnt in scope. variables inside WSM/WSM_graphs_test cannot be accessed from server.R by default

shiny_server_1  | update button 1
shiny_server_1  | Warning: Error in : Can not find symbol WestEnf_DataMatrix

[sythel]

updateDam1/update button 1 is called when preferences for dam1 == 100 and the "update" button is clicked

[sythel]

I was planning on making methods generateDam1... generateDam8 to generate plots/tables that rely on data from WSM

[sythel]

server.R line 510

there is no variable a

output[[paste0("WSMPlot", damId, a)]] <- renderBarPlot( 

I assume you want

output[[paste0("WSMPlot", damId, "a")]] <- renderBarPlot( 

[elbfox]

Yes, error is line 630. I'm hoping I have this figured out now...I didn't realize that you were no longer using WSM_graphs_test.R (oops!) and wrote the individual dam tables into there to make sure everything was looking good. I have pulled them into the WSM.R script now. These can be removed later if that cleans things up...I know you were working on tables and while I don't want to duplicate efforts, I do need to do some table & graph comparisons here to make sure everything is calculating correctly for the individual dams.

I will comment out that output for now with the a.

[elbfox]

Yes, output[[paste0("WSMPlot", damId, "a")]] is right
