Clean fluids are fundamental to reliable system operation. Many companies know this and place value on fluid conditioning, fluid analysis and filling with clean oil. What cleanliness requirements are there? Condition-based maintenance and system components that work flawlessly and are the cornerstones for high productivity. With fluid monitoring, you can detect damage early on and avoid system downtime. Find out more now! How condition monitoring works: Start video now. It puts your hydraulic system and lubrication system at risk! Contamination in your fluids leads to devastating component damage and unscheduled system downtime. Inadequate lubrication increases wear in your system's parts and results in high costs. But be careful: there are two types of contamination that you need to keep an eye on.

Sustainable production Using materials and fluids efficiently enables more sustainable production. Reload to refresh your session.

TL;DR: If all you need is taking a look at a working example, please scroll down to the last code snippet of this article. ViewHelpers are nifty little functions for your Fluid Template helping you to render data into your HTML offering if-then-else-comparisons, localising labels, counting, formatting, debugging, and a lot more. Now imagine you want to render a sweet JavaScript element slider, but only if there are at least two items to slide available. In short you need to nest your Fluid ViewHelpers when you want something to be done with the output of another function that also took its input from some other function. In the example above the function f:format. Now the parameterValue is a function call itself with its own parameters.

Any newcomer to fluid soon discovers that the fluid way of doing things requires a completely new approach to development. In particular, simple things that you might have taken for granted in the classic interface now prove to be a real challenge in fluid. A perfect example is having to display more than one field on the same line. To understand why this can be a challenge, set up four fields on a fluid page and then view the page in the browser. Regardless of how the fields appear in App Designer — whether they are listed under each other or listed side-by-side or scattered all over the page — the resulting fluid display will look something like this:. The default style of fluid is to display all fields one-under-the-other in a single column. The first field shows the Employee ID, while the second field shows the employee name. By custom, PeopleSoft classic pages show both fields on the same line. Your users might be keen to follow the same approach in fluid. To see how this problem is resolved, we will take a systematic approach.

Use the dot. ViewHelpers are special tags in the template which provide more complex functionality such as loops or generating links. The "f" namespace is already defined, but can be explicitly specified to improve IDE autocompletion. Here, we are using a custom ViewHelper within the namespace "blog". The namespace must be registered explicitly, see the next section. Each of the rows will result in a blank line. Multiple import statements can go into a single or multiple lines. Fluid allows to register global namespaces. Therefore they are always available via the f namespace. Custom ViewHelpers, for example for a site package, can be registered the same way.

Solid Solutions in a Fluid Environment. Would you like to detect wear in gearboxes and drivetrains early on? A Renderable is a cross between a ViewHelper and template variable: but rather than parse the template and detect a ViewHelper class to initialize and render, you control the prepared object instance that gets rendered and assign that instance to the template. Median Dynamic Viscosity - Parameter 1. You signed in with another tab or window. Steps are described in detail in the support article Updating sensor configuration. Minimum Operating Temperature C Use with care - caveat emptor! Our systems make predictive maintenance possible. MathExpressionNode called before any conditions New issue.

Brand Bucher. Shop Storefront. RenderableInterface - render Objects directly in f:render NamelessCoder commented Dec 5, Fluid has "if" and "else" behaviors, but it also does "else-if" which can be used to add a condition to an "else" node, making Fluid continue evaluating until an "else" is matched or a final "else" without condition is found. Different ways of importing Namespaces This example is VERY small; the bigger and more costly the rendering is, the more sense it makes to use this trick. That's not possible for Layouts. When you expand the expression to use nodes, those get parsed but not evaluated until the ViewHelper starts rendering. Benefit 4 : Most obviously though, this strategy makes the rest of the template far cleaner to read since most of it will simply be dealing with f:if and f:render to output or pass your assigned variables. The "Export" button will automatically triggered. Will close this issue as "works as intended, by design". There is however a way to avoid it: by assigning intermediate variables and whenever possible, passing content as child node instead of using a named argument.
