Bug Description

I am learning how to conduct structural equation modeling analysis. I am following the example that is being shown in the following video: https://www.youtube.com/watch?v=fno5LC5cKdM. I am using the data set included with JASP - Political Democracy.

When I include the following syntax, the analysis works.

#latent variables
ind60 =~ x1 + x2 + x3
dem60 =~ y1 + y2 + y3 + y4
dem65 =~ y5 + y6 + y7 + y8
#regressions
dem60 ~ alphaind60
dem65 ~ directind60 + beta*dem60
#effects of interest
indirect := alpha * beta
total := indirect + direct
proportion := indirect/total
#residual covariances
y1 ~~ y5
y2 ~~ y4 + y6
y3 ~~ y7
y4 ~~ y8
y6 ~~ y8

But when I click on the "Standardized estimates" option in Output options, I receive the following error message. "This analysis terminated unexpectedly, Error in x$[[<-(i, value): Did not get a vector or list as column..

Stack trace
withCallingHandlers(expr = analysis(jaspResults = jaspResults, dataset = dataset, options = options), error = .addStackTrace)

analysis(jaspResults = jaspResults, dataset = dataset, options = options)

.semParameters(modelContainer, dataset, options, ready)

.semParameterTables(modelContainer[['results']][['object']][[1]], NULL, params, options, ready, modelContainer, dataset)

[[<-(*tmp*, 'std.nox', value = NULL)

[[<-.jaspTableR(*tmp*, 'std.nox', value = NULL)

x$.enclos_env$private$setField(field, value)

[[<-(*tmp*, field, value = NULL)

.local(x, i, j, ..., value = value)

x$[[<-(i, value)"

I don't know what this means.

Expected Behaviour

It should include the standardized estimates in the output.

Steps to Reproduce

Error disappears when I unclick "Standardized Estimates" and it reappears when I click on "standardized estimates"

Log (if any)

@aazaragc thanks for reporting the issue. I tried this out now in a development version of JASP, and I cannot reproduce your error. This means this will be fixed in the upcoming release (a few weeks from now). If you dont want to wait you can try a development nightly version that contains the latest changes from here https://static.jasp-stats.org/Nightlies/
